My pc was sitting there on desktop and i happened to notice it reboot itself in front of me. Now, it doesn't post, the only real thing ive tried is clearing the CMOS. I think it may be the power supply because its a cheap piece of crap, and btw the fan on it is REVING hardcore on startup. MY proc is O.C. to 3.6 ghz 450 fbs x 8 but i got a tuniq on it and it averages 55 load. So i dont think its the proc its just a possibility. Would anyone like to help me figure out why my computer is all the sudden so instable?

specs:
Asus P5B Deluxe
e6600 intel core 2 duo
Gskill HZ 1gigx2
maxtor 200gig SATA 150
nVidea 7950GT <-- i think is known to be a power hog if i'm not mistaken
sound blaster audigy 4
a Full tower case with 4 120MM fans (inc tuniq) and 2 80MM fans
suspected issue: coolmax v-500 500W power supply

well i havnt tested anything out but i gota strong hunch the psu is the problem, mainly cuz its brand name, cheapness and its lack of ability to keep its fan going without killing itself with the fan blades.... so if i gota like get another one i was thinking this seasonic 500W

although, i was thinking about getting an 8800 equivalent card when DX10 games come out... plz recommend a nice psu for around 100-150 bucks with enough wattage to supply an 8800 equivalent. what are the chances of a local store having a good psu

Have you tried running the CPU at stock speeds to see if the problem continues?

Anyway, here's a 700watt unit that is highly recommended by DFI/DIY Street for $10 less after mail in rebate.

i would personally take my cpu back down to stock clock speeds and try to boot, if that doesnt work, then i would take the psu out and use a spare one. im sure u have more than one comp in the house.

Jaggar

yea the thing is, i guess its like not.... its showing nothing on the screen when i turn it on. and clearing the cmos will return the speeds back to normal which i've done through jumpers.

btw theres no link i could see dryadsoul to that 700 watter

new update analysis, power to both my mouse and keyboard are negative. Case Fans are all on and turning, video card fan going. No response from PC says monitor. Does this further indicate a psu issue? or could it still be anything

Hi.

I would start troubleshooting by testing the PSU, or better yet try another PSU. Do you know someone that has a unit that you could borrow for a little while?

Eliminating the PSU as the culprit will be a definitive step.

and just now i do remember seeing a.. what looks to be a power plug icon in the bottom right hand corner, and that started to happen about 3 days ago when we lost power.

Do you have a UPS on this? If so, that power plug could be Windows Power applet from the Control Panel.
