AMD PC shows black screen when stressed

post #1 of 4
Thread Starter 
Hi!
I got Amd x2 4200+(toledo), asrock 939dual-vsta, asus silent square.

When I stress CPU with SuperPi, then monitor screen goes black, but stays working(doesn't go stand-by). PC keeps working aswell.
I have to shut PC down from button in order to get screen working again.


Temps: Core 1 - 45C, Core 2 - 51C

*** is going on?

Hmm, everest shows that voltage is bit more then needed(12V is 12.8V etc.)
And 400W should be more then enough for this PC
I put tester between power plug and monitor, speaker and pc wires. It said 140-220W(220W was while running Counter Strike Source and SuperPi)

This problem has occured in past 2 weeks.
I've had this PC for approx. 8 months.

Edit: Seems that you were right!
I removed TV-card and the screen didnt go off

But now I got different problem.
Everest shows VBAT Battery as 0.53V. It should be 3V or what?

the MB batt should be 3v+ and if it was weak you would have issues booting or saving BIOS settings. I don't see how it would have any effect once your in the OS.
