Tactical,

I believe my problem was the CPU. I called the Gigabyte Tech support and followed this procedure to find the problem.

I disconnected all connections with the exception of the power supply, heat sink, heat sink fan. (no connections to HDD, CD Drive, removed RAM, removed Video card, disconnected all system fans, sata cables ect....)

I then powered up the computer. It had the same power issue of starting and turning off, looped.

I then removed the Heat sink and CPU from the motherboard but kept the Heat sink fan connected. So I only had the motherboard, P/S and fan connected. Started the system. No power issues.

I cleaned the CPU and heat sink (took off old arctic silver) reapplied and reinstalled heat sink/cpu. Just in case the heat sink had shifted and was not cooling anymore previously. Started up system. Power issue was back. I called INTEL and I have sent CPU back for RMA. It was only six months old. Be aware that you are supposed to use the stock CPU cooler that intel gives you. Even though my Thermalright ULTIMA 90 is better. They say it can void the warranty if you use a non-stock cooler.

I will post when I get info on the new CPU and what Intel can tell me.

Hope this helps

Well,

Got the new CPU in.

Did not fix the problem. I will have to call GIGABYTE on Monday. I believe it is the motherboard but fault only shows up with a CPU installed.

I had a similar problem with a IBM notebook and it was the microprocessor that had failed and could not regulate the flow of power into the capacitors and resistor or something along those lines , anyways there is little chance of repairing that problem without replacing the Motherboard which i did do and hey presto was back to new , all same memory and CPU and bits just the bare board should revive it
On another note there is a lot of specifics i am not aware of about your problem and set up so dont go out and buy a new board, first of get yoursaelf a free estimate first and drop it into a computer store just to confirm they will have a mini pci slot adapter that can run some tests which will give error codes relating to the board if that be the case

You should try manually running the fan with a program. That works for me.

That is... if you can even login

No offense to no(will never hurt my peeps) but Gigabyte mobo's sucks.I had a really weird BIOS prob with a gigabyte mobo yesterday and boy was there alot of people struggling with the same prob operating on a gigabyte mobo

Yeh man, get a hamster or a mouse and do a wheel cage thingy and make sure u stick the cheese a bit far so mouse runs real fast. link the fan and u r sorted....lol

Jokes apart but we have had many troublesome gb boards, wont be surprised to see a hamster powered one on one of these.

good one.lol

Programs of such do exist <.<

Maybe you might be unaware, but even motherboard software can manually run fans if they aren't running themselves. Also adjusting speeds as well.

Dude i'm aware of what you meant and didnt mean no offence, it was just a light hearted humour man. We all need to keep things on the lighter side. Other than that we are all trying to help each other on here.

It can get real gloomy in these boards sometime so a joke or two wont hurt once a while....eh

Take it easy.
