Bad PSU???

[Raku]

I looked through the faq and guides at the top and didnt see anything to really answer this.

Hooked my psu up to a cheapy tester; 20 pin and 4 pin main connectors check all green, 4 pin molex and fdd connectors check all green. SATA only shows green on 12v and 5v, the guide on the testor says that SATA should be green on 3.3 too. Is it wrong, or do i have a problem? Environmental test in sandra says 3.3v is only 2.0-2.3v and 12v is only 11.*v

The system(SFF 300w psu) has had problems with locking up and rebooting, and my tuner card is not working right( bad/no image or audio). After a few reboots windows will finally settle down long enough to get an error report that says bad device device driver, update to the newest driver or reduce acceleration on your video card. It has gotten this error with both a 6800gt and an old quadro dual display card.

After a few attemtps to repair/reinstall XP, it was rebooting during the installing devices section, everything seemed stable except the tuner card until I installed the critical updates. After that reboot the lockups started again.

Any thoughts on if this is a power issue or something else would be great thanks.

3.3 missing on the SATA connector isn't a problem; no 3.5" drive on the market uses it. What does a multimeter show for the +12 and +5 voltages?

havent looked at that yet. been busy setting up another system, testing components, and stress testing the system to see if anything fails. As soon as i can get everything pulled apart again to get to the power leads ill dig up a meter.

Still havent put a meter on it yet, but here is what i have found.

tuner card is dead, same problems in another system(maybe the cause of all this)

+5v is good from all soft readings, bios, sandra, solteks hw monitor, and speedfan. all show +/- 3% or less

+12, dunno, sandra and speedfan show it in the 10.8-11.3 range. bios and soltek hwm show 11.9-12.6

lockups mostly happen after a cold/re-boot. after 2 or 3 tries windows gets going with no other problems, although it didnt like me trying to reinstall the mobo drivers, took 3 tries.

and now the bad news, the error windows is reporting is our old friend "nv4disp.dll infinite loop". im not exactely motivated for that frustration right now.

Ill update when i have new info
