|I have had a couple of system crashes out of the blue over the past few days. It's not even the Blue Screen of Death, just a blank screen, followed after a few seconds by the BIOS booting up from scratch. The crashes happened under fairly low-load conditions without having many heavy apps open or anything otherwise exceptional happening with the system.|
The system is XP SP3 on an HP Pavilion, Intel Pentium 4, 3.2 GHz, 2GB RAM.
After the reboot the MS diagnostics conclude "clkdvr.sys has stopped working properly" as a reason for the problem.
I have searched the entire system and failed to find an instance of clkdvr.sys anywhere (YES, I did of course include system files and hidden files in the search).
Also I cannot see "clkdvr" or anything remotely similar among the running processes in Task Manager.
I do have MSN Messenger installed but I don't use it a lot, it is not started on boot and it was not running when the crashes happened.
The resident Avira antivirus (free version) and Webroot Spy Sweeper did not detect anything suspicious in connection with the crashes, before or after.
Does this ring a bell with anyone ? Any suggestions on further troubleshooting steps?
