Computer slows down over time?  SLi problem or motherboard?

I would try updating the game to the current patch.  It sounds like there is a memory leak, because you are not the only person to have these problems.  Here is the current patch http://battlefield.ea.com/battlefield/bf/BF2142_News_112406.aspx  Don't forget to check the official site frequently to get any more.\n\nYou can also try deleting your video cache and let the game reoptimize it.  Just in case, the location is "&#92;My Documents&#92;Battlefield 2142&#92;mods&#92;bf2142&#92;cache", just delete everything in this folder then start the game and load a map in single player. Dont move the mouse while it is loading/optimizing, just let it do its thing until the map loads up.

1. Check the fan, if the cooling system is bad the processor will automatically step down its speed\n2. Remove all spyware and viruses by installing a good antivirus software\n3. Make sure you un install all software that you dont need. Any thing that runs in the back ground such as database services etc.\n4. Check how much RAM is currently being utilised and which processes are taking max cpu time. That might give you an indication which program is slowing it down.\n5. Check memory for consistency by doing a memchk from command prompt. Also check that CMOS setup detects the right amount of memory installed (2GB in your case)\n6. Try using Firefox browser. Its more resilient to spyware etc.

I don't believe you have a RAM  issue, I believe you're overtaxing your processor.  Depending on the type of processor you have, you can only accomplish so many tasks at one time.  You also might have too many background programs running at one time, on top of the programs that you initiate.  Download the program I have supplied a link for below, and find out exactly what's running on your system.  Turn off anything that's not system critical this should free up some processor time.

You need a new motherboard. With that, you'll need to reinstall Windows due to the change. It's not a simple deal. Since the sockets arent the same with the old pin configuration to the new 939 socket that the X2 runs on, you need a new motherboard. Pick a good SLi board, you'll be glad you did.

The most likely cause is faulty memory. Make sure that the dimms are correctly seated and if you have more than one try using them one at a time to find which is faulty. Also make sure that you are not overclocking your PC.

Its possible your graphics chip is overheating.  Check the fan.

I also have a self-built system.  Generally if your problems occur after starting a game its going to be one of two problems.  Heat or Video Drivers.  Because you're having problems on all games and not just one or two in particular, I would guess that its a heat issue.  Generally an outdated driver won't affect all games in the same manner.  However, playing games are usually the most resource intensive applications and generate more heat on the CPU and GPU.  One way to test the heat issue is to open the case and find a big portable house fan and blow it directly on the computer and see if you can play for longer.  Also verify all the case fans are running properly and are installed properly.  Since you built the computer yourself verify that you have at least two intake fans in the front of the case pulling cool air in and two exhaust fans blowing out the back.

Its probably ur motherboard's that causing the slow down. Try reinstalling ur drivers for ur pc (graphics card, sound etc.). If it doesnt work, reinstalling SP2 might help, most of the time, its just a rare one-time error

Your computer is probably slowing the operation not the usb bus. Install windows defender, and avg free. Run both scans and then make sure that you have all the windows updates installed. If the PC is still slow you may need more RAM.

This Problem has two sides to check out\n1. hardware related.\n2. software related.\n\n1.hardward related.\nIf you think you own an old computer it's time to upgrade some parts .. mainly think of adding some extra RAM memory nd if possible change your processor (but refer to some expert to get you a processor that fit your mainboard.\n\n2. software related\nthis has various possiblities \na. delete TMP files.\nb. delete BAK files.\nc. Run an anti virus scan with an updated antivirus software\nd. run a scan to detect and delet spyware files.\ne. run disk defragment on the system partition.\nf. empty at least 700 MB's in your system partition.\ng. uninstal any unused softwares.\n\nThose should aid your computer and if you wish to remove the operating system and install a fresh new copy that will help too -- but you better backup your important files and system state before continuing with the fresh installation plan.

If this is a problem that started out of the blue without you touching any of your settings, chances are there is a problem with either your motherboard, graphics card or processor. I had this same problem and it turned out that my motherboard had burnt out.\n\nI don't know how old your computer is but if it is more than 3 years old, chances are it is burnt out and you will need to replace your base unit.

i would also check for spyware, do a scandisk/defrag this should help

This is most likely a hardware issue.  Have you installed any new hardware recently (right before the problem started)?\n\nPossible solutions:\nCheck for new drivers for your motherboard.\nCheck for new drivers for your video card.\nCheck for BIOS upgrades.\nIf you bought your computer from an OEM (e.g. Dell, Gateway, etc.), try going to the vendor's website and see if they released any new driver packages.

A) run defrag  (if you cant find it search your computer for it through start -> search\nB) Try deleting stuff that you don't use.\nC) Buy more RAM\nD) Buy a better graphics card (it has its own memory s well)

It might be the battery on the mother board might need to be replaced. Do that first.

Try having a qualified technician check the wiring inside the computer between the hard disk and the controller on the motherboard.  This can be particularly flakey with SATA drives.
