No warning, machine quits

Hi Everyone

I'm running a HP Pavillion (751n) with XP Professional (upgraded from XP Home).

If I run any utility (chkdisk, Full Norton Antivirus Scan) or run any game (e.g. Age of Empires) the computer will *snap* and down it goes. No warning, just instant shut down. It even happens when running PC Certify diagnostics from the A: drive.

Nothing of any import shows up in application or system event viewer. Dr. Watson doesn't record anything.

When I start the machine up, I don't get any dire messages (like "the system has recovered from a serious error")

I've updated the SiS board drivers, but still the same.

Anybody have any ideas?

Just a guess, but if the psu is the oem version, I would take a look at that first. The psu weakens with age, and a failing psu can cause many problems.
You really can't have too much power, only too little.

I use this computer for work, so its on all the time running Visual Studio. It's also stable when I do graphics stuff on it. I don't think its the power supply or it would show up more randomly.

The only time it drops like a stone is when it plays certain games or I run utilities like chkdisk or Norton.

There's your clue.

Since it fails when you make it do work, the higher current draw points to heat or power issues. The heat issue is easy to find. Remove the case cover and point a fan at the internals. Better? Good, now find what/why its too hot.

The power issue is simple too. Fit a new PSU with 100 more Watt capability and see if the issue vanishes.

Shame on me! I pulled the cover on the machine and found a nice thick (and insulating) layer of dust. A little compressed air cured the problem.
Ran Norton all the way through without a hitch.

Thanks to both you guys. Got to start paying attention to routine maintenance.
