Hey everyone, I recently built a new computer (yesterday) and it was working OK, but I noticed a couple things. First off, the PC would sometimes boot, shut down, and reboot again. When I mean boot I mean all fans spin to max and then power off at about 5 seconds. I thought that was weird, but I installed windows and everything seemed OK. However, today it seems as though it won't want to POST! The PC turns on, all lights, fans, etc, and after about 5 seconds shuts down and keeps repeating the cycle.

I tried new ram, From Gskill to Corsair RAM. I tried removing ALL ram and still did not get any beeping error for no ram. I removed video card, I even reset CMOS by disconnecting CMOS battery and re seating. However, nothing works with no input to screen and it won't go into BIOS! I disconnected hard drives, disk drives, fans (except CPU FAN, obviously) and its still cycling! What is going on?

I have heard about the PSU but I doubt it is it. I unplugged the 4pin CPU power on the MOBO and it still boots but shuts down much quicker with no fans spinning up, so I think the CPU is still functional since this change occurs. Also, I have used that CPU in my previous computer for months with no issues what so ever. I put a 4670k in my old one and put the 4570 into the build in question.

So what can it be? I have heard MOBO shorts could be an issue, but nothing is contacting the MOBO from underneath and I have unplugged all cables except essential power switch and Power connectors. Could the motherboard possible be faulty? Again, it did act a little weird even when I first booted up.

ALSO! BEFORE YOU LEAVE! I have a bitfenix prodigy iTX case. I screwed it directly into the case, on the little INBUILT standoffs. Is that wrong? Some cases need separate screws.
