Blender crash problem

I’m using Blender 2.41, and until just a little while ago (some days) it has worked fine. But now it is beginning to crash/freeze after approx. 15 minutes of work. It isn’t triggered by any specific thing i do (as far as i can tell).
The program just stops, and i can’t do anything in it. My PC works fine, other than that (except that it works quite slow)

I’ve tried to re-install Blender (downloaded a new installation-file), but it doesn’t help.

My specs are:
Microsoft Windows XP Home
Blender 2.41
Intel Celeron 2.6 GhZ
512 mb DDR ram

Do a virus scan most likely youve contracted something.

I’ve virus scanned, and it hasn’t helped a thing…

There isn’t any system in the time it takes, from startup until crash…
When it freezes/crashes, the CPU usage reads “100%”

Any other suggestions as to what i can do?

What’s your video card?

What do you have running in the background? Under the Ctrl-Alt-Del task manager.

ATI Radeon 9550GE (Asus)

and i have nothing running in the background

theres your trouble right there. do a search in Blender General for Radeon fixes, theres a few around, hopefully one will remedy your situation :smiley:
