Hello all, I am unfortunetly having some troubles with a custom build rig of mine. I've had it built for about a year now and It's been working fine. I've recently upgraded the GPU and have had no problems with it either.

Unfortunetly, going back to college I think something may have happened to it. First, I used the wrong power cord that was for a monitor. I figured it would be no big deal as it should have worked. When I plugged everything in, my computer started acting weird. When I turn it on, it turns on for about a second, then turns right back off again. But, after it turns off it turns back on by itself after a second and doesn't sound so good. Also nothing is showing up on my monitor, which is hooked up via HDMI.

I can't really think of what the problem could be besides the PSU, but it's a weird issue seeing as how it turns off then on again.

For those interested, I have a Thermaltake TR2 RX 850W PSU.
