ok the other night before i went to bed i just turned my pc off without turning the psu switch off.
next morning i woke up and tried to turn my pc on, it turns on for 3-6 seconds without showing anything on the monitor then shuts off.when the pc is on everything is working led, fans etc but just doesnt boot i suspected it was the psu so i went to buy a psu 0cz stealthxtreme 700w to replace my coolermaster 650w. however the problem still there. i think its the cpu but im not too sure i dont want to go buy a new cpu and realize it wasnt the cpu like my psu.
i know some people had some success in booting their pc by constantly turning it on but i dont want to do that incase it damages the whole pc. i havent had a successful booting since that morning and now i have to go to the internet cafe.

oh and i havent tried to remove my cpu yet cos i dont know how to cant seem to find a removal guide online for my heatsink as i think its the first thing i should remove.

i am willing to call in a guy to repair my pc but they cost so much £80 per hour exc VAT? lmao i dont mind if that includes cpu replacement too. i only have £100 left to spend.

There's locks look around. I suspect cpu overheating. Did u check the cpu temp in bios before. Do u hear any beeps. Try to remove ram and start the system.

it isnt the ram i removed them. i check the system bios in cou before it was running at 60. but if its the cpu wouldnt the pc stay on but not do anything?

i found a jumper cap at the3 bottom of my pc i looked at the cmos jumpers and theres already a cap there unless it goes onto the second row of pins/jumpers?

If cpu oveheat the system will start for a few second (no signal) and then shutdown itself to protect cpu. U didn't post the result, when u remove ram what happens? Beeps or still the system shutdown for a few seconds? Before buying new cpu, remove cpu heatsink clean it and apply new thermal paste and see what happens. I think Jumpers u found is for clearing bios, there's no need to clear the bios leave it.

Ok, try to remove heatsink (it's no that hard), make sure both heatsink and cpu surface are clean then apply small amount of new thermal paste on cpu surface.

"i check the system bios in cou before it was running at 60"

60C at idle? That's pretty hot, not overheating but definitely much hotter than is should be. The temp at idle *should* be under 40C.

well i remember i turned my my fans to the max and it was hovering around 45-55 and while in windows mode it was 60ish but i turned it down back to medium on the switch as it was making too much nosie and it was at 55-60 in bios. i dont know why i mean isnt my heatsink good enough?

I think the heatsink is fine but better clean it.
