- Motherboard: MSI MS7529 v1.1
- Mem: System Memory: 4GB
- CPU: Intel Core2 Duo E8400 (3.00 GHz)
- HDD: Seagate 500 GB SATA Drive
- Video Card: NVidia GeForce GT240
GT 240 recently replaced my old 9800GTX which failed when I shipped my PC cross country and the clumsy baggage handlers apparently fondled it inappropriately. I replaced the video card and installed Windows Vista Home Premium from my friend's OEM disc and everything worked fine for a short while. I installed the LAN drivers from my friend's flash drive then just downloaded the rest of the drivers myself. Most of them Windows Vista took care of automatically. Then, one day, I accidentally interrupted the installation of an apparently critical Vista update and my computer has not worked properly since.
Next time I booted it, it seemed to be stuck in an infinite loop of attempting to roll back and then reinstall the update that I had interrupted. After leaving it for several hours, it returned to normalcy. Until I noticed severe framerate problems in games that had previously worked flawlessly, namely World of Warcraft and Call of Duty MW2. Virtually anything that requires even moderately intensive GPU calculations will experience terrible framerates. I've tried reinstalling the video card drivers over and over. My friend recently tried expanding the pagefile to see if it was a memory problem but that just resulted in severe artifacting in World of Warcraft. However, it wasn't artifacting in the sort of way when a video card is about to die, but hinted more at a video ram error as it appeared in a definite, repeating pattern.
If anybody can suggest anything to fix this issue, I'd greatly appreciate it. I'll be checking the post frequently today as I need the computer to complete a homework assignment I've been working on for months.
