Computer Won't Turn On

[InfinityHardware]

This is a bit of an outside chance but check all front panel connections all the way to the switches. I had this issue a few years back were the on switch was shorting out and causing my computer just to shut down randomly, took me about a week to figure out lol

Have you tried powering up the PC by shorting the pins on the board?

Ok I will have my friend try that.

Check that all your psu power cables are plugged in properly and all your motherboard standoffs are installed properly. There could be a short on the motherboard causing the computer to turn off.

do a once over the power connectors to make sure they're all plugged in correctly and haven't fallen out.

try to boot it with one memory stick at a time moving channels to see if maybe the memory or channel is dead, with that you'll be able to see which one is defective.

if none of those work try testing his psu with this method:

(universal for all psu's, not just corsair)

​i'd do the psu test first to avoid having to boot the system many times with a defective psu :)

Pease get back to us with results

maybe, doubt it though

Power supply by the sounds of it.

Yeh even tho its not pulling the full 650Watt, this paticular PSU does not have a good rep, some work some dont. By power hungry I meant not a basic build (duel core with no video card ect ect)

The problem has developed into something else. His computer can turn on and will stay on for a few days but will randomly trun of and then stay off for a while. I plan to check the PSU soon. Anything else thatI should check?
