Hi there Viper,

I am not too sure what to recommend as you did not tell us anything about your system specifications. What operating system, processor, RAM type etc. There are quite a few diagnostics proggies out there but no point in suggesting one that won't work on your box?

I have another thought though What is your hard drive, and its specifications.

In recent years hard drives have got bigger, so their associated cache has grown as well. Processors have also become much faster, FSBs and so on. Now, when your HDD shuts down, the HDD cache should be written to the drive....but sometimes the system can shut down too quickly for that to happen, giving you data corruption.

There is actually a Microsoft fix for this, that basically inserts a pause in the Windows shut down sequence to let the HDD complete its shut down! Once again, I would like to know a little more about what you are running.

EDIT: Sorry, what do you mean by "corruption"? what exactly do you notice.

Cheers
