Sadly I can't do a remote login here, this PC is not on a network. I'll leave the memtest running eventually, but I never had this problem running windows since I bought it, and it has been about 2 years. I didn't try to insert a CD, but I will next time. The CD autorun is not making the unit light flash ever.
I assume you are running the generic "vesa" driver? That seems to help for me.
On mine I see the disk light flash when there is no cd installed. Not sure about when a cd is inserted if it stops. But I guess if music keeps playing after lock that indicates no crash too.
Someone below mentioned going with fc3. Possibly it fixes these type of problems. Guess I had hoped fc2 whould become stable like fc1 was reported. Maybe I will move to fc3 when I get a chance. Hopefully a clean install would not be required?
