How do you turn off restore and your recycle bin on your computer?
Before you hide the recycle bin you need to know that its a bit of a saga to get it back.There are articles in Microsoft help and support worth readingclick start >help and support > search for - recycle bin does not show - and look in the microsoft knowledge base results down at the bottom of LHS column.System restore on off instructions are located in the system restore tab that is a tab on the properties screen of 'my computer'Note that once it is turned off, all your previous restore points disappear., but you have another recovery in safe mode that can be used if you need to.Click f8 while booting and select last known good configuration. This is a step up the ladder from system restore.
Core 2 Quadro Review
With the advent of the Intel Core architecture earlier this year, it became clear that Intel was back at the top as the performance king for the desktop processor market. Intel has shifted right away from clock-scaling and the Netburst architecture, and moved towards better performance-per-watt ratios and increasing the number of processing cores. The Intel Core series CPUs come in three main varieties:
Core Solo: Single core CPU, code named Yonah, designed for notebooks; there will soon be an Allendale version for desktops.
Core Duo: Dual core CPU, code named Yonah, designed for notebooks.
Core 2 Duo: Dual core CPU available for both notebooks (code named Merom) and desktops (code named Conroe for 4 MB cached chips and Allendale for 2MB cached chips).
Intel plans to release a quad-core edition of the Core CPU some time during Q4 2006, codenamed Kentsfield. This CPU is to be available in QX6600 and QX6700 varieties. Each will have four cores clocked at 2.4GHz and 2.66GHz respectively, and 8MB cache, 4MB per each pair of cores. The Kentsfield, to be called Core 2 Quadro upon release, is to be the first quad-core CPU available to the desktop market, giving unprecedented performance to everyday users.
Essentially this CPU is just two Core 2 Duos slabbed on one PCB. One of the things that disappointed us most was that the 8MB of cache was not shared between all four cores, but rather only 4MB is available to each pair of cores, limiting single threaded performance to the equivalent of that of the Core 2 Duo at equivalent clocks.
It seems that after the disappointment of Netburst, Intel is rushing to reclaim the performance crown by rushing out the Kentsfield by the end of 2006. It was originally planned for a Q2 2007 release. By producing it using their 65nm transistors rather than moving to 45nm transistors as originally planned, they are able to have it ready at the end of this year. This may potentially lead to heat concerns; while the Conroe didn't have any heat issues, Kentsfield, being essentially two Conroes, each having a TDP of 65W, leads the Kentsfield to have approximately 130W TDP. That is somewhat shy of the furnaces that were the dual core Netburst chips, but it still produces a rather worrying amount of heat, which may limit its overclock with conventional cooling methods.
Today we'll be looking at the Core 2 Quadro (Kentsfield). The sample we have is a QX6600, clocked by default to 2.4GHz per core, with a 1066MHz front side bus and a total of 8MB of cache.
Here is an image of our sample chip. The Core 2 Quadro is on the left, and a Core 2 Duo is on the right. They appear essentially the same, with no major differences other than the wording. As you can see our Quadro reads ES A4, indicating that it's an early engineering sample, while our Duo reads ES, indicating that it's intended to be identical to retail. Therefore, our chip may differ somewhat from retail Quadros.
Here is an image of the LGA (land-grid-array) of our two chips (Core 2 Quadro on the left and Core 2 Duo on the right). As you can see, the chip uses the standard LGA775 socket, which means that is should be drop-in compatible with most boards that run the Core 2 Duo. The most modification required should be a bios update, providing an exciting upgrade path for Core 2 Duo users.
We installed the CPU into our test setup, and quickly attempted to boot the board with success on the first run! The board posted correctly and the POST screen read: "Genuine Intel® CPU @ 2.66GHz Cores: 4". What surprised me was that it ran perfectly on our board with all cores being detected and with no need for a bios update.

How to Upgrade a Notebook
Many people know how to swap out their hard drives or install new memory in their desktops; you might even be able to build your own computer, but that is on the desktop platform. When it comes to notebook computers, people feel less at ease. Why is that?
It's because of the size you have to work with; everything is compacted into the size of a college text book. Another reason is that finding parts isn't as easy as for desktop counterparts. We will try to help all you nervous users with opening up your notebook computer and make upgrading it as easy as a desktop.
Before you crack open your computer, you need to figure out what is inside and what you want to upgrade. Compatibility is far worse for notebooks when compared to desktops. With desktops you can pretty much use any part you want and it will work, but with notebooks it's not that easy. It's better to first figure out what you have in it now, and what you wish to upgrade.
Upgrading the whole "guts" of a notebook is nearly impossible since each model differs in size and space. Some parts are going to be compatible across the board, but many will not. While it is best to buy directly from the manufacturer, this will more than likely result in a higher price tag than what you could buy at a third party web site.
CPU
CPUs aren't as tricky as you may think. A notebook CPU is very similar to its desktop counterpart. Mobile CPUs tend to clock slower, use a lot less power and put out less heat. The only thing to really worry about is to make sure it is supported by the chipset, and that a BIOS is available for it.
If the manufacturer sells the same model notebook with a higher CPU, it will more than likely work without problems. I would like to point out one thing as you pick out your new CPU: Pentium 4 Mobile is not the same as the Pentium Mobile! This will certainly not work no matter what you try, so don't try it.
Finding mobile processors will be harder than finding desktop CPUs. You can check out your local computer store, online retail stores or even eBay. From my experience online and brick and mortar stores will charge you insane prices for a processor. The best place to check is eBay; stick with very reputable users. I have seen CPUs that sell in stores for $200 go for as little as $40.
Memory
Picking out memory is fairly easy. All you need to do is check to see whether you need DDR or DDR2, as you would for a desktop, right? Well, yes, except you're looking for SO-DIMM memory. Both DDR and DDR2 use SO-DIMM, so picking out the notebook from the desktop shouldn't be that hard. This memory is competitively priced at online stores such as Newegg.
Today we will take a look at the Gateway 6000 series. The specific notebook model we'll use for our demonstration is the 6020GZ. It contains 512 MB RAM and a Celeron CPU. While this is usable, it isn't going to be very fast, and our goal today is to speed this fellow up some.
An important step you should take first is to see if there are any BIOS updates for your computer. Check your manufacturer's site for details. If you are installing a new CPU, the update may be required for the BIOS to work with the new CPU. If you realize this after the upgrade, you will need to reinstall the old CPU, flash it, and then redo everything. While looking at the Gateway site, I noticed that they have provided a useful PDF of many upgrades for this computer with pictures. This how-to will go over some that aren't given in the document.
The good thing about this computer is that it is very simple to get into. Other notebooks won't be so easy. I suggest reading the user's manual and any other documents on the manufacturer's site about the guts of the computer first.
The first thing you should do before touching your computer regardless of make of model is shut it down, unplug the power cord and remove the battery. Also, don't forget to ground yourself; one static shock to your computer could fry it beyond reasonable repair. Doing these few simple steps will make this upgrade successful and safe.
On my Dell Inspiron 6000, you need to practically take the whole computer apart to get to the guts of it. With the Gateway 6000 series, I only need to remove the bottom cover. There are a few screws that are holding the cover in place. Simply unscrewing them and removing the cover will expose the main parts of the computer. I have to give Gateway props for making this so easy. After you open it up you will see the big copper cooler and fan. To the right of these are the memory slots.
This one came with one 512 MB stick of memory, which left one slot unused. All you need to do is insert the other stick into the slot, make sure it is in, and then push it down until it pops or locks. This is fairly standard for all memory in most notebooks. Think of the pushing it down as using the clamps on a desktop board; it just helps to hold the memory in.
The next step is to pop a Pentium Mobile into this computer. First we need to remove the copper heatsink and fan. There are three screws holding it down. Unscrew these screws to access the CPU and graphics card. It is easier to unscrew all all at once as opposed to one at a time; it helps relieve the pressure from the components more slowly and evenly. It also helps you avoid putting force on a certain side of the cores, which may cause them to break.
After you remove the heatsink, unplug the fan wires from the motherboard. If you yank them out and break the fan power socket, it is going to be either a long night at your house or a costly trip to the repair store.
Popping the CPU out is fairly easy. You need a screwdriver and a little twist of the socket screw. This should allow the CPU to pop right up and be easily removed. Then it's an easy matter to pop the new CPU right in. After you have it in securely, the only thing left is to put it all back together. There is however one important thing you need to do first.
This part will drastically reduce the heat problems many notebooks face. Conversely, this may also explain why your computer's fan might be on all the time or how loud it gets. Many manufacturers use some rather crappy thermal pastes. Gateway is no different.
I removed what they call thermal paste from the Intel chipset/GPU, which was some stick pad (I don't know how great it is, but it clearly wasn't helping any) and anything left on the copper cooler. I used some rubbing alcohol and a razor blade on the copper cooler. Be careful not to scratch up the bottom of the copper cooler. I used Arctic Silver, which can be found for roughly $5- $8 online. This is one of the better thermal pastes out there. I applied a small coat to both cores, and then put the cooler back on. Again, I was very careful to slowly tighten both screws so not to apply too much pressure on one side at a time.
After all is well, you should remove it again and take off the cooler. This time make sure that the copper cooler has the dark silver imprint of the cores on it. If not, you should reapply the thermal paste and make sure it is seated correctly, maximizing the surface area to which the heat is transferred. If it isn't making complete contact, you are going to be trying to cool the core with only ½ of it being able to transfer heat. This is going to cause overheating or even kill the CPU!! When you're finished don't forget to plug the fan back into the motherboard. This is often forgotten and not good for the computer.
If everything is good at this point, you're basically done. You just have to put all the screws and covers back in. Make sure you don't have any thermal paste outside the cores. Also check to see that nothing is loose and that anything that doesn't belong is gone. After you've checked carefully, screw the cover back on. Now plug in the battery and power cord and you are ready to go!
I hope this little how-to has helped you understand that upgrading a notebook yourself isn't out to the question. While it will require more attention to detail, it is no different in principle than a desktop PC. As always take your time, be careful and it will turn out fine. Doing the few upgrades listed here has turned this run of the mill PC into a machine that is up to multitasking -- it runs cooler, too. If you have any questions or need help with any upgrades to your notebook, visit the Dev Hardware Forums where very knowledgeable members or myself can help you get your questions or problems answered.

How to increase virtual Memory on My computer?
Usually running out of virtual memory means that you are running too many applications at the same time for your system or one of them is attempting to use too much memory. Increasing virtual memory is one way of compensating for lack of RAM. However, it's optimum should be set at 1.5 times the amount of RAM on your computer. Virtual memory can be increased, but it comes with a risk if you increase it too much as it can eventually lead to hard drive damage.To increase VM on Windows XP (should be in similar locations for other versions) look in Control Panel: System, Advanced, Performance Settings, Advanced, Virtual Memory. You can see if your computer can handle more RAM at http://www.crucial.com/index.aspIt's important to note that everything takes RAM. Not only security products (such as active anti-spyware, anti-virus and firewall) eat up memory but your operating system, active browser windows, running applications (such as Word, Gaming, Messenger, Photoshop, etc) and malware all compete for system resources. The presence of Malware (viruses, spyware, etc) will particularly eat up your system resources so you may want to run your resident security products such as antispyware and antivirus applications to ensure that your system is clean.
