Help: Is my motherboard or PSU broken?

post #1 of 8
Thread Starter 
Hi,

I've been experiencing a lot of trouble in the last year. I had a faulty power supply which produced a high pitched sound. When one of my hard drives died, I blamed it and changed the power supply. A few months later, the other hard drive (Raptor 150) also died. Over this time, my system has started refusing to cold boot more and more, since reaching the point that most of the times it does not boot. I have to boot, listen to the motherboard beeping like there's no graphic card plugged and then reset. Then it boots. That was until last week, where the system wouldn't even resume from suspended state (I got a BSOD every time), and the hard drives were slower than usual (both are almost new).

I blamed the radeon, but after days of testing it in another computer, I see no problems at all.

The problem I have is that I don't know how to be 100% certain that the motherboard is the faulty component. I know it's not the GPU, memtest86+ reports no error, and the system is prime stable.

The only idea I've got left to try is completely erase the nvram and flash again.

What do you think? What can I do?

PS: Will rep any useful comment.

I've noticed you mentioned the system is prime stable, do you have your CPU overclocked? I can almost guarantee it's an unstable overclock. I'd go ahead and revert all of your settings to default and see if these issues stop. That way you can definitely rule out your overclock.

Have you tried clearing the CMOS? That might help, if not then I fear that it is your motherboard considering you have tested everything else.

Flash it and if that doesn't work I would say the mobo is toast.

I'm going to go with this, you seem to have tested every other component... the only thing other than that is making sure your motherboard power connectors are properly fastened.

I've tried reverting back to stock (in fact I've been running OC for only about 6 months) and same problems.

Yes, I have cleared it like 5 times

I even changed the ATX 12V 4 pin connector to 8-pin EPS 12V just in case

I think I found the cause. I plugged in my old (and supposedly faulty) Tagan power supply, and the system booted 5 times in a row. I went back to the Antec TP New 550, and only booted 1 times over 6 attemps. I powered off the UPS before every attempt.

It's ironic, considering that I bought this PSU to prevent more damage to my system (as I think it killed one of my hdds), and another one died few months after installing the new PSU.

Now I found that the Anted power supply will boot if I disconnect the dvd recorder... I don't know if that's the cause, or another symptom.

Can this be moved to power supplies?

Edit: I've attached a sound that comes from the PSU when I run an application at really high FPS (like the menu of a game). I don't know what's going on.
