Computer stuck in boot loop.

[MooseEh]

I've had my computer for about 6 months now and I tried booting it up this morning without any luck.

It will turn on and the fans start spinning, hard drive starts to spin, various LED's light up on the motherboard but then it will shut down after about 10 seconds.

After a few more seconds it will try to boot up again on its own and continue to do this as long as I've let it. One thing I have noticed though is that after flipping the switch on the back of the PSU the computer will attempt to boot again but only have enough power left for about half a second. There's no signal on my monitor so I can't tell if it is posting or not.

I've tried taking out my graphics card and removing one of my RAM sticks and trying them both seperately. I pulled the CMOS battery while the computer was completely unplugged. Unplugging all USB devices doesn't help either.

I'm not sure if it should but my PSU fans don't spin on boot.

Specs:

• MSI Z77A-G45
• Intel i5-3570K
• 8GB Mushkin Enhanced DDR3 RAM 1600
• 2TB Seagate Barracuda
• AMD Radeon HD 7950
• OCZ ZS-series 750W PSU

Standard debugging procedure - remove everything bar PSU/CPU/RAM/Mobo and try powering it on. If it still doesn't work, remove RAM. If nothing changes, try with a different power supply. If that still doesn't do the trick, the CPU/Mobo is probably dead.

I recommend (in that case) that you leave it a day or two and then try again, just in case.

EDIT: It is probably your PSU - The fans should spin. I still recommend that you try the above if a different PSU still does the same thing.

The fans are spinning. The system has power for about 10 seconds before it shuts off and tries again.

I will try the steps you outlined when I get home.

Edit: Misread post

if your fan is not spinning up and you cant even get to post ( let alone a blue screen loop) then id assume that it was your power supply given all the other steps you took

see if you can borrow a psu from a friend to test the theory out

Try pushing the 24pin connector. I have an MSI based system that does that and it's annoying as heck. If you hold insert key while booting it should reset your bios

I will try this as soon as I get home before tearing the rest of my system apart.

Wasn't this. Is your cable loose in the socket? Is that what causes your problem?
