URGENT: Dead CPU?

post #1 of 13
Thread Starter 
OK, i just built my mates computer. have built plenty before so was like, "yeah man, no worries, i'll do it".

hes got a Q6600 G0, ASUS P5K, HD 3870, 2x 1gb Team Xtreem PC6400 DDR2, 600w Silverstone Strider PSU, 1x 320gb HDD etc etc...

so i connected everything ok, did have a little struggle with the stock cpu cooler (hate those f*kn things..why dont ppl just buy aftermarket straight away? lol) but its seated as good as you get without cracking the bloody motherboard.

all cables were done correctly, everything was sweet, so we turned the power on. the computer comes on, all lights/LEDs light up, even hear the hard drive spin.

then all of a sudden, it just gives up? switches off. i never heard a post beep. i've reseated the CPU like 3 times, even cleaned off the stock thermal paste and applied my own. i removed both ram stick, tried them on their own, in different slots, all that. the PC doesnt sorta like, click or anything when it shuts down, it just gives up. almost like it loses power. cant be with a 600w PSU though.

i have a bad feeling, that SOMEHOW, i've killed the CPU. i would like to know how though?

just to further my fears its the CPU, i tried turning on the computer without the vid card plugged in... didnt even beep at me. just booted, all fans span, all lights came on, then it gave up and turned off. then it tries to turn back on again.

help a brother out? any help much appreciated.

If it was a bad CPU I would think that it would just sit there and not keep cutting off.

Try Unplugging everything from the MB HD, mice etc. Then take the MB, PS, VC out of the case and hook all of them up on a piece of Cardboard. This is to rule out all accessories malfunctioning as well as the case stand-offs being in the incorrect place.(I know that sounds crazy but I have seen it twice with ppl who would have bet me $100 that none of them were in the wrong place.)

If this does not work I would try another PS.

I was thinking the same thing. I had a friend's computer do the same thing, start up and suddenly switch off. Try testing the psu.

i did read about that somewhere. has never happened to me before but i'll check. i didnt drop any screws at any time though. if its shorting out or i've somehow shorted it out, is it ***d? i would rather buy him a new mobo than a new quad core anyway lol.

thanks ill check it out.

yeah i did all that. my first thought was the PSU, i just didnt wanna admit that it was, since its a good, strong PSU, more than enough for his system. i've never had the unfortunate result of a bad PSU out of the box, but i guess my mate could be the first for me haha.

the ONLY thing i have not done yet, is remove and re-install the motherboard..maybe one of the stands is in the wrong place? i would be one of those betting you $100 lol coz i cant see how i got that wrong..but i'll look into it.

cheers.

If you think it's the cpu. Try using cpu on other mobo to see if it boots. If it does then at less you know its not the cpu. Good luck

I would vote PSU. If it were the cpu, i'm sure you would get some beeps. No beeps generally means no power or a bad mobo (Knowing ASUS at the moment somewhat likely)
Swap out the PSU for one you know works. If still no luck, you might want to look further at the mobo.

I reversed a USB connector once and it displayed the same symptoms.

Could be the power button. Turn the motherboard on with the screwdriver.

ok. so wait, you mean you had them in the wrong way and your PC wouldnt boot? i dont understand how. surely that would just mean the USB ports would fry if something was plugged in..ill check that too then.

hmm. no coz it powers up, stays on for about 5 seconds? then just fails, like its struggling to maintain power. hence my initial blaming of the PSU. but i could see how it might be the mobo cutting out.

when it turns on, i dont hear any beeps and it never posts. i mean, i turned on the machine with the vid card deliberately unplugged and it didnt even beep at me.

oh and yes, the PC speaker is plugged in haha.

i feel like such a noob. this is my first fail. Mission: Fail.
