Display blinking to black on HD3850

The particulars:
Intel E8400 processor
Gigabyte GA-P35-DS3R motherboard with F10 bios
Two 1GB sticks of Corsair XMS2 PC6400 DDR2 ram
Windows XP Pro w/SP2
Visiontek HD3850 256MB video card
No overclocking whatsover!

Without rhyme or reason, the display will occasionally "blink" to black for a second, and then return to normal. It can happen under a full load, or under minimal load, without any apparent pattern. No particular program or task seems to affect the random nature of the occurrences. There is no artifacting under load, or anything else that seems to be wrong besides the blinking of the display. Any and all help is greatly appreciated!

It wasnt random but i did get an issue where my screen went to black while changing between apps or pages. It turned out to be driver related in my instance.

re-install vid card drivers, if that doesnt wrk then i would try the monitor with a diff pc, re seat gfx card and make sure monitor is plugged in properly lol

I am also having this issue with similar hardware:

Saphire HD 3650
Gigabyte ex38-ds4 Bios F3
Intel Xeon E3110 3 Ghz
2GB of Corsaire XMS2 PC6400
Windows XP SP2

I have tried reinstalling the card with the latest drivers, re seating the card, and reloading my PC. This is also completely random for me. The monitor works fine on any other PC. My next step will be to contact saphire and go from there. If I figure anything else out I will be sure to post it.
