PC turns on for split second then off when turning on the power supply!

[GustavEngvall]

So, 2 days ago I built my PC, it was working fine until yesterday night when I decided to plug in my HDD and un-plug my DVD (cause I only had 2 sata-cables). But now the PC won't turn on. The only time its on (for 10 milliseconds basically), is when I have plugged out the power supply, plug it in, and press the power supply power switch. Boom, it on for a short period of time (fans start, GPU lights up etc.) then it turns off. The power button on the PC doesn't work. Note that everything was working before I unplugged the DVD.


How can I fix this?

we have to find the problem first.
did you try with the DVD drive again?

I once had a bad HDD that would keep the system from powering up. it's not unheard of

Well yes, in fact I did plug in the DVD again. It still wasn't working :/

What I think it might be is that when I plugged out the DVD I think I've might "hit" some other cable in the PC that depending for the PC to work.

basic troubleshooting it is then. Ground yourself before working in the PC. try to boot after each step. reground before each step
1. reseat every cable in the case, unplug and plig back in
2. reseat the RAM
3. unplug the SATA cables
4 remove the RAM. listen for beep codes
