Windows Vista Upgrade to Win 7 crash no BSOD

[devildog4]

I recently upgraded my computer to windows 7 ultimate and it works a lot better from what I had, but since the upgrade my computer has been crashing a lot. I know that you'd usually get a BSOD with a error code of some sort but for some reason when it crashes I get this weird series of repetitive patterns on my screen. The crashes happen quite often but the weird thing is if I use Firefox or do anything on my computer it crashes in like 5 minutes, but if I play video games like Battlefield 2142 or Counterstrike soruce I can play for hours without it crashing, and once I get off of the game to do something it goes back to crashing again. Im not sure if I need anything for my computer, its pretty old. Here are the specs. If its the hardware it would be appreciated if you can recommend anything low budget for an upgrade . Thank you

Can you be more precise about what happens when it crashes? You see a "weird series of repetitive patterns." I'm guessing this persists until you reboot?

If you did an in-place upgrade (that is, not formatting but doing an upgrade install) you may need to update the drivers (specifically video driver). The hardware there obviously isn't high-end, but I'm assuming you don't have much put away for upgrades. Diagnostic tests are available for memory (ex, memtest86+) though memory issues would usually be more random.

Go to your mobo site and check first for athe latest BIOS update, and then for any and all hardware drivers that support Win7, mobo chipset, ethernet, sound, set...upgrade the BIOS then all drivers

A new problem just persisted when I start up. When it starts its extremely laggy, if I click anything explorer.exe basically fails on me, and like I said, if I do anything its guarenteed to crash. I check task manager and the highest thing taking up the memory is SCVHost at around 45,000k which is normal for my comp. When it crashes , uh lets say im on toms hardware, the website is white, when it crashes ill see a streak of white thats repeated like a pattern and it goes across my entire screen. I did a memory diagnostic test and it found no problems, I also updated my Nvidia driver and the problem persisted. The only way to basically use my computer is if im playing a game which is very weird. Also my internet wont even start up when its on normal mode, and half my services are stopped and wont restart.

Might want to do a safe boot with networking and download MalwareBytes (either the free or the trial version) install and run it, with updated drivers and all, sounds like possible malware
