Specs: Windows vista home premium, celeron 256mb
I am looking at my friends PC which keeps shutting down.
Mobo - GeForce 6100sm-m 2 gb Ram
It is running windows vista home premium. Lately it has been shutting down after 10-20 mins of normal use (internet etc). It has slowly started to shut down sooner and sooner. Now it gets as far as loading vista (green bar moving left to right) and it shuts down. I thought it must be overheating so ive reseated the CPU with new thermal grease and the BIOS tells me the temp ok (40c). If i try and run the vista setup disc the exact same thing happens.

I am able to run tools to test the memory and the hard drive and theres no problems with either of them. The memory tests have run for an hour or so with no shutdown. I have even tried an XP setup disc, and this again works fine and takes me up as far the screen which allows me to create / remove partitions before installing. I hope this makes sense because I am at a loss at the moment. Any ideas????

To rule out if it is a Software issue, swap his drive with yours and see if it boots with your Windows Install.

And, see if his drive boots on your system,

If you attempt to swap the hard drive from system A to system B, it won't work because Windows is configured for system A. And if you make any changes to try to get it to work in system B, then change it back, it will no longer work in system A. You're gonna end up with two systems that don't work.

Where and how did you check the temperatures? If you checked in the BIOS that is at system idle. Under load the temps can go up.

If you are using Vista tools to check the memory it may not to a thorough job.

Download memtest86 and run it from a boot disk run the full program. Takes more than one hour, depending on the amount of RAM.

Desktop computers get pretty dusty inside the case. Open it up and look. Use canned or compressed air to blow it out. DO NOT use a vacuum cleaner. Will be messy, may want to move to a different location to blow.

While you are in the case you may as well re-seat all the cables, cards and memory. Snap the RAM stick in and out 4 or 5 times each to burnish the contacts.

All the above is good maintenance. If the computer still shuts down then install a temperature monitor like Speedfan to see if the temps are the problem or not.

Not true, all you have to do is hit no to the Found New Hard Ware plug and play pop ups when the system boots. Besides I am not asking him to log in just to see if they boot.

So what Jam said is kinda true only if you allow the system to install new drivers.

Beside, even if it does just F8 boot and boot to last know good configuration.
