Computer turns on then off...ideas?

Okay so it turns out the copy of windows I had was counter-feited, which was aggravating, so I got another version of windows and while I was installing it, the computer restarted (as it normally does) and then the display wouldn't come back, so I restarted it and looked up what the issue was, as it turns out the RAM wasn't all the way seated, so I re seated the RAM and that's when things got ugly. I started the computer and the CPU and D_RAM LED lights started going off simultaneously and then the computer shut down, I tried the power button but no use, the only way to turn the thing on is by the switch in the back, if I plug it into a wall, or if I slap the case. I've tried re-seating the CPU and the RAM and I've gone through the sticky with no luck. Any ideas as to what it could be? Maybe static?
Update: Okay, so I installed the stand-offs and now the computer turns on, stays on, but shows no display. The RAM, CPU, VGA, and boot device LEDS all flash. Ive tried different graphics card and different sticks of RAM with the same issue. Ideas please?

  1. Your PSU is 100% complete junk. Replace it ASAP with a quality unit from antec, XFX, Corsair, Seasonic before it damages your computer.

    I picked it up last second from a newegg deal. Is that what's causing the issue?

    Thermaltake PSU are NOT good. Look at the brands I listed. Those are what to stick with.

    Your PSU is probably the issue.

    Alright, thanks for the input, I'm going to try re positioning the MoBo on the stand-offs and trying a different PSU. Will update.
