Is this a PSU issue?

Installed a second gtx280 about a week and a half ago, and everything was working fine for about a week.

Then, this past weekend, I get a blue screen on startup - just after the windows logo, before the logon screen. I restarted the computer and it starts up fine. A day goes by and I restart my computer again, but this time it takes 5 restarts to boot up without a blue screen (same part of startup every time).

I have stress-tested my system (after these issues), and had no trouble with either video card stress tests or processor tests. My temperatures are all still low, and once the computer is started up, I don't have any issues.

The only thing that I can think of at this point would be that I have a power supply issue (since I've had friends that had issues with PSU's and they manifested primarily on startup).
 
What happens if you try and boot with only one video card? Do you still have the problem?

It seems odd that the problem would only occur at startup and not during a stress test of the video cards. If your power supply couldn't feed both cards you would think a stress test would duplicate the problem.
 
I'm going to try booting with each card (disabling each of the PCIe slots with the jumper on the mobo one at a time) this evening... I didn't have the chance to do it over the weekend.

I would suggest that you physically remove the cards instead.
 
didn't get a chance to test tonight, going to do it tomorrow... I'll physically remove the cards, but do you recommend testing them both in PCIe slot 1 when I try them one at a time?

Temps are normal for 280's... 50 or so idle, 65-70 gaming, 75-85 during stress testing
 
I don't think the slot will matter, but just in case, I would try both in the same slot.
 
okay, i'll test it out tomorrow... the one 280 has been running fine for me for over a year and a half now (a couple months in its current slot in this computer too), so I'd be surprised if it was the culprit... the other one... who knows...
 
turns out, it was a driver issue... re-installed the 196.21 drivers and all is well again.
