Windows 7: Computer is shutting down randomly

With the computer cold, i.e. has not been used in 30 minutes, I would remove the panel on the side of the case to maximize airflow, disconnect the hard drive, then boot straight into the bios health status page and watch the temperatures listed there as they heat up. I normally do not jump to any conclusions about temperature but your earlier report of 75C really stands out because not only is that very unusual, if your cpu is that hot then the rest of your system is also too hot, and motherboards are far less tolerant of high temps than a cpu. If a cpu gets too hot it is most likely going to enter a thermal throttling state, and next most likely is that it simply freezes. For a system that keeps rebooting I would suspect the motherboard or power supply. Also check to see if your chipset heatsink is firmly attached.

ok people.
I am still troubleshooting this time following this document from Tom's hardware:
http://www.tomshardware.com/forum/30...shuts#r5136625
I am following BEST ANSWER in green.
So I tried this:
Breadboard with just motherboard, CPU & HSF, case speaker, and PSU.
When I turn the PC on I hear the beeps indicating there is no memory, (that is good I guess), but after about 25 seconds the computer will reboot itself on a loop.
Same problem.
This is the original reboot loop I had.
What does that mean??

I guess that means my HDD and Memory are not the problem, but what is the problem then?

Thanks a lot. I have like 3 more hours left for troubleshooting.

If the system reboots when it has no memory, that's probably just what the system does when it has no memory, not indicative of anything imo. Those links you found are good, so you might as well continue down the thread. Be aware that the beep patterns in the thread may not match your board.

Hi
Replaced memory and still boot loop. Sometimes faster, sometimes slower.
Sometimes it takes like 2 seconds to reboot.

Also I found this thread:
http://www.tomshardware.com/answers/...boot-loop.html

I tried his solution but I see no recovery screen as he sees.

Actually I saw anything on my screen after that.

I am lost. I had enough for today.
I will continue tomorrow.

Thnks a lot

is the beep pattern the same both with and without memory installed? The fact that the system reboots is not important if there is no video card running yet.

Can you boot to safe mode yet?? and the driver for your graphics is an Intel one - GA-Z77X-UD3H (rev. 1.0) | Motherboard - GIGABYTE
under VGA I would also do the chipset.

To save me wading back through the thread have you checked out the PSU??

Hi.
Not able to boot to Windows.

My mobo is Rev 1.1. All drivers up to date.

PSU is fine. Tested with a Multimeter.
