Today I finally retired my trusty old Enermax 460W PSU, and upgraded to an OCZ GameXStream 700W. I removed the old Enermax from my case, plugged in the new OCZ PSU, and now my system won't POST. When I press the power button, all the fans start up, I can hear the hard drives powering up, and I can hear my optical drives looking for discs, but I get no video signal.
There is no way that the PSU could be underpowered because the system ran on a weaker one previously.
I plugged in the 20+4 pin main power, the 4+4 pin CPU power, 2 SATA power plugs for my optical drives, 1 SATA power plug and 1 molex plug for my 2 hard drives, and PCI-E plugs into the video cards.
What I've tried so far to no effect:
- removing my RAM sticks and trying them each on their own
- using each of my video cards one at a time, and in all 3 PCI-E slots
- reseating my video cards, PCI sound card, all IDE/SATA plugs, and all the power supply plugs
- plugged in my OLD power supply (Enermax 460W) that I had been using up until 2 hours ago
- using the CMOS clear jumper to reset my BIOS
- used an alternate video card that I had laying around (GeForce 7950GT PCI-E)
- 3 separate monitors plugged into each DVI port on all 3 of the video cards I've used
- reseating the CPU
Is there anything else that I have not tried that could be causing the problem? I'm open to any suggestion, even if it's something that only a "newbie" would forget.
I'm at my wit's end here, the only other thing I could imagine that would be causing this is that the motherboard died at some point during the switch of PSUs. I reach this conclusion because the computer will not POST even when my old power supply is reattached and the new one removed. Does anyone know what is going on?
I noticed that after I had initially installed the new PSU, when I went to plug the monitor cables into my computer, there were some extremely small static sparks. They were almost invisible so I didn't really pay them any mind.
I know that the fan in this power supply is supposed to have a bright blue glow, and I noticed that when I turn the computer on, the power supply fan doesn't glow very brightly at all. The fan spins at full speed, it's only the light that doesn't seem to be working properly. I don't know if this is relevant but I figured I'd mention it for the sake of completeness.
