MMm sounds a bit strange indeed. I have had something like this happen only once. If you have an older PC or know someone who has a (at least) 300W PSU you can switch and see if it works fine .that way you will know for sure if it is the PSU or not, these things can be pricy. Other thing would be to check the motherboard (crack? check connectors) or the small motherboard battery (sometimes these need to be replaced) its the round flat battery.
Hope this helps
Keep me posted
ok so currently my specs are 450w psu, 3 gig ddr2 ram, 9800gt 512mb, an a triple core 2.1ghz processor an untill recently my pc was working just fine. Untill tonight whilst i was playing cod waw and it just turned itself off, i thought it was a bit strange so i turned it back on and it turned off while booting up.
I have tried most things i can think of ive checked all the wiring and taken the graphs card out to see if this was the problem but nothing worked. I also thought it might be the fact that the card was not fully connected but trying it without the card verified it was not the card.
Im hoping you guys will know, i think its my psu but theirs no point in buying something if im not sure, any help at all is very greatly apprecicated.
the annoying thing is i cant keep it on for longer than like 10 secs so i cant look at the bios or anything.
