Thank you for the quick reply.

My system is a Sam460LE with a X1950 XT GPU. I ran the memtest with the extensive flag for about 20 minutes, no errors so far. SFSDoctor says "Filesystem structure is correct" on all 3 partitions!

Edit: I also ran memtest with the vmem flag and the system crashed. During the test, the screen got black and then white (guess that's normal for a video memory test) and when the desktop appeared again, everything but the mouse freezed.

Edit2: Did run the vmem test a few more times. No more crashes...
