pc wont boot after slight overclock

[yugurt]

Hi when i tried overclocking today my pc turned of while running prime95. now it won't boot and my powersupply makes a little buzzing noise.

specs
amd phenom x6 1055t
x2 asus 6870
870A-g54
kingston hyper-x 1600 Mhz 4x2
silverback 620w


i ran prime95 for about 45 minutes before the crash and i was constantly checking temps and they maxed at 45 celsius.
my FSB was at 245 when the crash occured

When you say it won't boot: what exactly happens? Also did you tweak any voltages or anything or did you just adjust the clocks. The latter should be pretty much harmless.

nothing on the mobo lights up and no fans or anything start. and yes i just changed the clock

maybe a loose wire?
just do the usual checks... e.g check temps of other componants

my pc stayed at normal temps all through the test and i have tried disconnecting everything and then reconnecting it. will try clearing the cmos and also try running it with minimal components

fried PSU ?

Reset the CMOS.

Reset the CMOS.

I already did

Reset the CMOS.

That's the most generic response I have ever seen without proper explanation.

Since you aren't seeing any lights or fans spinning, it could be that your PSU is gone like FangedBeast mentioned.

ok this is how it is. i have rma the psu and thaey said there was nothing wrong with it. my mb needs a 24 atx cable and a 12v 8 pin connector to run. with the 8 pin plugged in nothing happens but without it the fans and mb lights up but nothing more. now i have 2 options either i buy a new rma my old one. what should i do? @Alen?

Disconnect all power to your pc, Including the little flat battery on the motherboard Leave your pc unplugged for an >Hour< When you reconnect your pc after that hour it will reset to factory settings (so no overclock nothing else will change)

As said i have already tried reseting the CMOS
