My system switches on and fans spin, but it goes no further than that, so it's not posting fully... After lots of testing i've narrowed it down.. I just need your opinions as to what part i need..

I'm not too sure what the voltages are supposed to be before the system posts, but i tested psu with a multi meter and the voltages were roughly (2v)(5v) (11v)

I have brand new memory, so it's not that... I tried my graphics card in my mates pc and that worked fine and i don't have anything else plugged in !

So that leaves m/b, psu or cpu ?

Just before it conked i noticed the small chipset fan wasn't spinning cos it was caked in dust, so maybe the chipset got fried ? I put my money on the m/b, what you reckon ?

Thanks guys
 
Was the pc working after you put the new memory in?

I would have thought the pc would be blue screening or rebooting if the chipset was getting hot before it fried.
 
I actually was getting random blue screens, but then they gradually got worse... Then sometimes the system wouldn't post until i rebooted it a few times, which is when i started to investigate and after investigation it wouldn't post at all lol :)
 
Arent his voltages down? 2v and 11v doesnt seem right to me, and thats with a multimeter, if his 3.3v is down to 2.9(and it could be lower as he said it was 2.something) somethings amiss in the PSU isnt it?

Well that's what i thought at first, but i checked my mates Dell XPS with same multi meter and his was reading 10v on the 12 and 1v on the 3.3v at the boot stage, so i just presumed they don't put out the full power until in windows etc :confused:

and i can't get a totally accurate reading cos the multi meter unfortunately only measures whole numbers

Odd going off mine, it stays around 3.35v and the 12 v at 12.15 v on a multimeter from switching on to going into windows, the only time i get a very slight drop is when i full load the GPU and everything else, never below 3.3 or 12.1 though even full under load.
But thats just my experience could be totally wrong.
Thats with the OCZ 600w mod xstream psu, so same brand.

Well i have no idea to be honest :confused:

I think i need a better multimeter to get a more accurate reading, but like i said my mates XPS was showing lower voltages than mine and booted up no problem :confused:

Oh i dunno, it's driving me nuts :(

Thanks for your reply
 
Problem solved :D

It was the m/b, i got the Asrock 785G and it now boots up a treat :) i'm just installing windows now :)

Thanks
