I just got myself a Gigabyte Nvidia 9800GT (GV-N98TOC-1GH). Been experiencing problems ever since however.
When playing games like CoD5 and CoD4 at resolutions above 800x600, the game goes on smoothly for awhile, until which it eventually crashes and well.. I can't turn it back on until i switch of the wall socket for a while and turn it back on again. And this goes the same for other applications which have some graphic requirements.
I'm guessing it's the graphics card because I've never had any problems when using my 7600GS.
Gigabyte S-series 945G-DS3 (rev 2.0)
Intel Core 2 Duo E6300
2GB (2x1GB) Kingston DDR2 667
Gigabyte Nvidia 9800GT 1GB DDR3
Samsung Writemaster Speedplus 16xDVD writer and reader
BenQ DVD3 16x DVD writer and reader
Maxtor 160GB 7200 RPM 8MB SATA
CoolerMaster RealPower 550W
I'm just wondering if the problem is related to clock speeds because my motherboard uses PCI-e x16 while it says "Supports 2.0 PCI-E x16" on the website (2.0 PCI-E x16 being one of the key features)
