is my PSU dying?

post #1 of 3
Thread Starter 
i have 4 SATA hdds + 1 SATA DVD drive, 2 x 260GTXs, 850W PSU. Asus M2N32 and Phenom 925.

Everything was alright for about 2 years. I think back then i had only 2 hdds + DVD. I gamed a lot and never had any issues.

About 6 months ago i added more hard disks. I think everything was still okay, but i'm not sure cause at that point i stopped using the computer regularly, and stopped gaming completely.

Recently, i've ran into a following problem:

It has become very hard to turn on the PC. I push the power on button and it's as if it powers on only half way or something. THe psu and mobo/cpu fans are all spinning, and have light but it seems like they're spinning slower, cause the audible noise is a lot less then what would be normal at idle. Maybe only some fan come on, not sure. When this happens, the PC doesnt post.

FOr a while, i was still able to get it to come to life by pushing the power button AND HOLDING IT IN until the whole PC came alive. As oppposed to quickly pushing and releasing. I've gamed a few times since then with no problems.

Today, i turn it on, copied some files from external disk, the PC became extremly slow and poorly responsive. I figured a reboot would breath some life into it. Reboot and bios reports it cant read the boot hdd, "press ctrl-alt-del". ok, i took out the boot hdd, but im still having power on issues, in fact, it has become very difficult to turn the PC on, the push-and-hold trick doesnt seem to work anymore. It freezes during the POST now. I put the removed hdd into a toaster and was able to connect it to laptop with no probs.

At this point I had to go to work, so i didnt have time to start pulling out components one by one, but i'm thinking its either the psu or more likely the mobo that's almost dead.

Opinions?

Thx.

Sounds like motherboard problems. HDDs barely use any power, upgrading those wouldn't really affect it.

I suspect the board because it is in charge of the power control, and turning a single momentary press into a continuous circuit on the PSU power cable (the psu requires a continuous short across the green and ground wires to stay on, rather than a temporary one). Also, a PSU problem would not cause the freezes and software glitches you were experiencing.

Try it with a different motherboard, then replace the PSU if that does not work.
