My monitor loses signal sparatically and screen just goes black. Now normally if I disconnect the VGA cable it would state "No Signal" on my HDTV, this is not occurring. I have checked power options in bios and in Windows XP SP3. Now it mainly seems to occurr when browsing the web with IE7. So far I have tried a different drivers, even a backup video card (7600GS) and did not eleviate the problem. So that can also rule out a possibility of a problem with the power supply too. Quick google search brought up overheating and driver issues. Coretemp currently shows 33C idle and about 51C load on stock. Video card is ok, idle temp 34C load 61C.
