Jerrye,

Have you updated your mobo's BIOS, drivers, etc, lately..? Is this your
mainboard..?
How about the video card drivers, updated them lately, what make or who is
the OEM ie..Chaintech, etc..?

Use the Everest home ver to id pertinent info/specs for your system..FREE

The video card might need the driver updated or reinstalled.. Get the manual
for your mobo from the DFI site and double check your connections , jumper
settings. bios info, FSB settings, timings, etc..
You can use Everest to paste selected info to posts or print for walkin tech
support..
Your PSU looks ok, Farly new.. How about temps, got enough fans to cool the
rig down, overheating can cause probs too..
The more info the better.
