Hello all!
About 2 weeks ago, I decided I was spending too much on electricity and decided to power-down my computer overnight and while I was at work. Normally, I leave my computer on 24/7 running UD (distributed computing). Upon returning home, I was unable to boot the computer.
I heard a "buzz" sound coming from the psu, and upon closer inspection, when I pushed the power switch (after unplugging and checking the cord, then plugging back in) the fan in the psu "twitched" while the psu made an electrical buzzing sound. The fan did not complete a full revolution.
System specs:
AMD Athlon64 3200+ 1.8ghz cpu
480W Thermaltake Silent X Purepower PSU
2x 512mb Crucial ddr-400
2x 120gb Western Digital 7200rpm IDE drives
2x SLI-Express nVidia 6600GT's
A8N-SLI Deluxe mobo
DVD-R/DVD-RW from Liteon
I just installed a brand-new Thermaltake 700w Toughpower psu, thinking it was a bad power supply. I got the same problem. The "buzz," the fan 'twitching' and nothing else working.
The lights on my mobo are glowing, so I know there's power going to it. I have disconnected all power adapters except the ones going to the motherboard, trying to get at least a POST beep, but nothing.
I followed
this guide and got down to the part that says: "Try drive in test pc." I have to skip this step tonight, because my spare computer is at my parents' house.
For a few months prior to this happening (and yes, this probably is the cause of the problem), whenever I would shut down the pc, I would get two long "beep - beep" sounds from the mobo, and then I'd have to shut down manually. Is this an indicator of a dead mobo? I have looked in the manual for the mobo but haven't found anything on the beep codes, and online documentation is spotty at best.
Thanks all for reading, and I hope someone can shed light onto my problem! Having just sunk $164 on a new psu only to have it "fail" too...I'd like to figure this out before my RMA period ends!
