Motherboard/PSU/CPU Problem

[tomtwostep]

Today while I was playing a game my computer made a weird noise like the fan was slowing down or dying, then it shut off.

Then when I tried to turn it back on it will not turn on. It does show the green light on the motherboard, but will not power up. It starts to and all the lights turn on but then it dies.

Went to the store and bought a new PSU:

New PSU w/ Graphics card - just twitches fans.
New PSU w/ only mobo connectors works, but the heatsink fan on cpu does not spin.
Old PSU doesn't work at all.

I don't know what to do at this point?

It really sounds like a PSU gone bad, but if you have replaced the PSU that cannot be the problem.
Try removing the CMOS battery for 5 minutes and then replace it and power on the board.
Try powering on the board without the RAM installed. Once you have done this you should here a series of beeps. If this happens your motherboard is working but your RAM is bricked.
If none of the above works the old PSU could have broke the motherboard.

Most of that is downright innacurate if not just wrong...


Kingwin is garbage, until you replace the PSU with something reliable, you cant even begin to troubleshoot...
That being said, unless the original PSU was a very good brand, it likely had no overvolt protection and fried one or multiple parts as well when it died...
This may be a matter of a rebuild rather than a fix...
Do you have parts to swap out with?
or is this a case of buying 1 piece at a time to test with...

That is what i said! "If none of the above works the old PSU could have broke the motherboard."

Untrue, he replaced the PSU with another garbage PSU, he could be having the same issue.

Try removing the CMOS battery for 5 minutes and then replace it and power on the board.

That will likely do nothing, granted it wont hurt anything, but its basically a waste of time, and all you have to do is unplug the PSU, remove the battery and hit the power button once or twice, you don't have to wait 5 minutes...

Untrue, just because the board beeps without memory installed doesn't mean his board isn't damaged, and this test certainly doesn't tell you anything about the ram status...
