Weird problem powering my pc

[sketchytom]

Ok so i push the power button and you can hear the hard drives reading. after this the pc just stops all power goes.

yet if i unplug the power to the motherboard and then replug it in ... asif by magic it works again?

so i tested the power on a asus f1a55 m le with a a6 3500 in it and it works perfect no issues even if i shut down then power back on

my pc specs are

asus f1a75 v pro
amd a8 3870k
amd 1600mhz performance ram
HD6670
some age old qtec 650 psu that has been used since my first pc

sweet if its just the psu no problem since on payday im buying a new psu and pc case since my case is like an oven

ive seen a bargain cooler master elite 334 case with a cooler master 460w psu for cheaps i may snap up since it is only 60 quid. that should be more than enough to power my set up.

well it is a classic psu i swear it about 9 years old. i did not want to use it but the psu i had running my a6 3500 just did not cut it when i added the 6670

psu will have to wait untill i get paid so hope the computer dont burn out within 2 weeks lol.

it weird cause once its on it works great although that psu is getting noisy and it was like a dyson before anyways

but as i said when it was on the a6 3500 with the f1a55 m le it worked a treat without this issue only since getting this mobo and cpu combo
