My power supply seems to provide voltages slightly on the high side, and I'm worried that it may be what is causing the instability on my computer (ie: random reboots without bluescreens). I don't think its my memory because I havent gotten memtest86 to fail yet (though I haven't let it run to completion). I've read about people who have increased the output voltages by putting a potentiometer between the 3.3v sense wire and ground, but is there a way to decrese voltages rather than increase? I was thinking if I somehow attached the pot to a voltage rather than ground, so the PSU thinks its supplying too much voltage, the voltage could be adjusted down. Is this in the realm of possiblity?

Obviously the easy solution would be to get a decent power supply, but that wouldn't be any fun would it?

Well, two things:

I thought you could change your PSU voltages through your BIOS, but that may not necessarily be the case.

Also, you have run memtest, but it hasn't completed? Whenever I run it, I let it go about 8-10 times through....

[Of course, there was that once that it returned 700,000 errors after running through once, but that was special ]

Well, I get through several tests without errors, so I get impatient.

Also, no. I can change the chipset, ram, cpu, and maybe other voltages in the bios. But in general, I think this particular motherboard must be flakey.

Yeah you definetly can't change PSU voltages in the BIOS.

How high is "slightly high"? I'm assuming you measured with a voltmeter correct? I wouldn't be worried if you're only running 3-5% over, but if it's like 10%, then that's pretty bad.

you can only monitor voltages in power supplies.. thats why its called a 'regulated' power supply... its regulated to a certain voltage.
