Turned on my pc last night for the 1st time in around 2/3 months and it didn't boot up.:(

It's a home made job around 4 years old all based on MSI K8N Neo Platinum 754 socket amd motherboard.

All that happens is it stops after around 5 seconds.It doesn't far enough to boot up to bios settings.

It does have sort of diagnostics board that shows 4 leds that go green if everything is ok or red if there is a problem,but i can't seem to find anywhere that explains the coding for this.

Any ideas would be appreciated.

Have a look at the mobo for bulging or leaking capacitors.

If there are any replace them, preferably all the caps of the same type if you can, and it will probably be ok

This sounds like your Mobo - Check the CPU first just to make sure.

I would suggest looking at the capacitors or the battery on the mobo - If any are looking abnormal or leaking then change them.

Goodluck.

Cheers.Will check motherboard.

I have done a little more digging regarding the leds and have found 2 things that it could be via the combination of the lights.

It could be something to do with the wireless keyboard i have.

Will take corded one home from work and try that.

Yes... could be capacitors, or also cpu heat problem if the heatsink has been knocked

Try msi website and d/l the manual (pdf) should have notes in there

If it hasn't been powered on for some time the BIOS might have lost power and corrupted - try a jumper CMOS reset.

Are you happy pulling it apart?

Sometimes memory needs to be reseated. Take it out and out it back in.

Further problems unplug everything (memory, CPU, drives) and put it back together one bit at a time booting in between.

Should help narrow down where the fault is.

Cheers everyone just got pc working again.

Cleared CMOS and plug in corded keyboard and everything is back to normal.
