computer won't turn on

[Underpowered]

my roughly 4 year old computer began turning itself off randomly. did this about 5 times, and the 5th time it bit the dust and refuses to turn back on.

Thinking the PSU was bad, i replaced it today with a new Thermaltake PSU.

still nothing. I get a very brief flash of the case lights but otherwise nothing. Attempted to cross the case power button leads and still nothing. Then saw somewhere you could start it manually by grounding the Green wire on teh 24 pin MB connector. Grounding it gets me the same ever so brief light flash and nothing more.


THoughts or ideas? is it junk?

Test the old psu in a different computer, or pull it out of the case and get a paper clip stick it in the green and a black wires, It could be your hard drive, but sounds like your motherboard.

I assume the Thermaltake is new? I would remove all hardware except one stick of RAM and see if it boots. If not try another stick of RAM.

Sound like your motherboard took a dump. 4 years ain't long but for some mobos you're lucky to get 5 out of it.

it was an MSI mobo, don't recall model exactly.

thermaltake is brand new. dont have any computers to test the old power supply in.

going to try to pull the RAM and see if it will boot.
