I've had a Gateway M-1631U laptop with Vista SP1 for about a year and a half. Not sure if it's related, but the cooling fan has always been loud.
Recently (within the last month), my wife has complained that it would shut down on her after about 10-15 minutes of use. Additionally, she's said that the bottom is very hot when in use.

This weekend, I was letting my daughter use it for some educational on-line games and we noticed that after about 20 minutes the computer would completely turn without warning. When we'd turn it back on, a screen would appear asking if we want to start normally or diagnose the problem (not sure of exact wording). If we picked the option to diagnose the problem, it would go to another screen that said it was fixing errors and may shut down a few times during this process. Sometimes it would die during this process and I'd turn it back on and find the same thing. Sometimes it would make through this scan and ask me to reboot. When I rebooted, I'd see a BSOD appear quickly and the computer would come back to the same "restart normally or diagnose screen". If I try the restart normally option, it will power off immediately.

The only success that I've had in getting it to reappear is to let the computer sit for about an hour. I can normally get another 10 minutes out of it and then the whole process begins again.

I captured the BSOD message and have it pasted below.

As one final twist, I decided to check into the loud cooling fan and hot machine. I took off the cover over the fan and saw a minimal amount of dust. However, I did not put the cover back on and the computer hasn't turned off for about 25 minutes and the fan is running a bit more quiet.

I don't know if the crashes were related to heat and the BSOD is related to a process not ending because of the overheating..I'm stumped.

Here's the BSOD information from Windows:

To determine if it's overheating, which would cause the computer to shutdown automatically, try measuring the temperature of your system with software such as HWMonitor.

Sounds like your computer is overheating. What MIGHT help is leaving it alone for a day, let it cool and try again the next day. It might be of use to buy some cooling pads from a shop that sells all the technology stuff. Laptops have a very big problem with overheating (including mine) so you have to let your computer cool quite a lot and never download too much software at once. Yes, games can do that to your computer, especially if you play large sized once (please don't blame your daughter for this, its not her fault)
I hope that helped.

I would open it up and clean the heatsink fins and fan, it may be plugged with dust and fuzz (especially if you own a cat, sometimes it looks like half a cat in there)
