Upgraded, now PC turns on and off...

post #1 of 7
Thread Starter 
Okay, I'm not sure if this is a PSU issue, but it's most likely so I'm posting it here.

I just finished upgrading my rig with the following:

1. Corsair TXV2 750w -> Corsair AX 1200w
2. Added a second GTX 580 for SLI
3. 2 additional sticks of 2x4GB RAM for 16GB total

Plugged everything back in, go to turn the PC on, it turns on, but nothing shows up on my monitor and after about 10 seconds or so it completely shuts down, then a second or two later it reboots itself. It keeps doing this until I manually unplug it or switch the PSU off in the back.

What can I do to possibly troubleshoot this?

Any help is appreciated!

clear CMOS and try again.. it's most likely a memory issue.. but it can also be a defective PSU.

How do you clear CMOS?

Depends on the mobo, some higher end models have a button on the back, most have a jumper, and the old school way is to unplug all power to the board and remove the battery for a half hour or so

Sounds like a faulty PSU

Check out my threads; different PSU, but very similar problems-

I would swap it out or borrow one to verify though...

Nope, it was the RAM. I took out the two sticks I added and it boots up and runs fine.

On second glance the added RAM looked funky. Now I notice if I try to added them no matter how hard I press it won't click in right and they don't match up... weird.. it's the same exact RAM..
