Why is my game crashing??
 

Computer: HP Pavillion Laptop, standard good stuff on there, all the windows updates

Game: Diablo II expansion running with a no-CD patch, over a LAN

Problem: whole computer locks up and has to be rebooted about every thrity minutes.

Solution: Is this an issue with windows/DiabloII/my computer or do I need to buy another CD off of E-bay?

Any patches for this on the Blizzard website?

Which pavilion? How much RAM? Which OS?

Have you checked temperatures? My old ze5170 will get hot and crash if it's run full-tilt without airflow assistance.

Its a zd7160us, though I think we've figured out the problem... I had the exact same experience on my old computer ever since Sage and I started playing Diablo II together, and it turns out (I think) that it was the copied CD I was using (and then later the patched .exe) that was somehow causing the whole computer to lock up (but only sometimes) when the game would check to see if I had the game CD in the drive.

Bought a new one, hasn't crashed since.
