Something wrong with my psu?

post #1 of 5
Thread Starter 
Hey guys, Ok so due to my dad complaining about his energy bill i don't keep my processor at 4GHz 24/7, but yesterday i turned it up to 4GHz and ran F@H for about 10 hours. My computer was stable during that whole time and was stable afterwards, i then turned it off for the night.

Well this morning, when i woke up, i turned it back on, but something was wrong. The POST screen was loading very slowly, and then never got past the DDR3 Ram speed listing. i hit the reset switch a couple of times, but it still did the same thing. my G110 keyboard was not lighting up also, so i couldn't get into the bios if i wanted to, so i tried to reset my bios.

That Didn't work either, in fact when i turned it on again after that, the POST screen began to become corrupted (numbers were replaced with symbols, parts of text were blacked out, ect) so i figured "crap my board must be fried".

Then i tried one last thing. i flipped the switch on the back of my PSU, left it off for a good 10 seconds, and then turned it back on, and all was right as rain. the Post screen loaded like it was suppose to, my keyboard lit up and i was able to access the bios and it booted up just fine, and i'm typing this from it.

Since the only fix was to shut off the PSU, i'm Guessing that's what caused it. My PSU is a Corsair CMPSU-750TX 750W psu (i dont know if its their original design or the new one they updated it to, but there doesnt appear to be any revision such as "-C" on it). Running an i7 920, 9GBs ram, and an XFX 5870 on it.
So my question is, does this perhaps mean that there is something wrong with My power Supply?

My pc does a similar thing: After any sort of boot (cold or restart) it will *sometimes* shut itself off and pressing the power button will not power it up. Gotta flip the psu on and off to boot it up again. Guess what: this happened on 2 psu's. I wouldn't worry about it, I mean I thought about RMA'ing but its not worth it for how little it happens. Just a ghost in the board.
