my 3d games suddenly stopped working after i tried an OC. I went from 100 to 126, and set the divider to 4 to get 2.27GHz with 32/63 pci/agp. the memory ratio was 2.0=252 (normally 2.66)

about 5 seconds into 3d games, i get a BSOD or it crashes and quits to the desktop.

shouldn't it work? the only thing i can think of is my power supply, which is rated for just 320 watts (brand ATNG). the system is below.
