I had a virus (browser redirect) trhat was masquerading as c:\windows\system32\dmload.sys - used AVG rescue CD to kill it

Can be corrupted by disk defragmentation, causing a hell of a mission to get your pc back to normal! Copy it from another PC, boot with a bootable CD, and overwrite the file before trying to re-install Windows after a Defrag crash.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem.
