Computer powers on for a split second then powers off - PSU problem? - Page 2

post #11 of 17
Booting the GPU's without external power won't damage them, I'm sure of that.
I've had to do it multiple times when debugging thumb.gif

Unplugged one, then both, no progress. Before I tried that though I tried starting it again considering it had been left switched off at the PSU for a while and it tried booting again, but didn't get to the BIOS this time. Just lit up for maybe 10 seconds then died again.

I've had this happen when I accidentally used the modular cables from a different PSU. It'd just click on, and right back off. Problem solved when I realized what I did and put the right power cable on..never mix and match PSU modular cables.

Reset the CMOS with them both unplugged, no difference. I'll have to dig around my case to unplug everything from the PSU so I can try it isolated so I'll do that tomorrow when I have better light.

PSU's dead. Isolated it and tried turning it on only for it to kick off again. I don't imagine it could've but hopefully it didn't take anything with it.
