Can you try changing the drive letters and see if it makes a difference?

Ok. I am lost on this one. Hopefully, someone with more knowledge than me will see this thread and have an answer for you :).

When you restart the pc, do the drives appear in the bios list?

Go to Start | Run and type in sfc /scannow and hit the Ok button. Insert your CD if/when requested.

Go to Start | Run and type in chkdsk /r and hit ok.
This will check for any errors and repair any found. It may take a while.

Do you have your XP OS CD?

Go in to the Device Manager and under disc drives and also DVD drives, locate the drives that are giving problems and double click on them.
Go to the driver Tab and select 'uninstall' driver.
When...

If I understand correctly, when you restart windows, the other hard drive and DVD drive do not show in the drive list?
Have you tried uninstalling the drives, then reboot and have them re-detected?...

You made it appear that all was well.

Please explain exactly the problem. Which drives are they? What is on them?

That may, unfortunately, be the case.

Are your graphics drivers up-to-date? That would be my next move. See if you can boot into safe mode after updating.
Let me know if your graphics card works ok.

I have uploaded that file for you. You need to copy it to the g:\windows\system32\drivers folder.

Let me know how you go and how the pc is after a reboot.

That is a good question :). Logs can be overly long and contain information that one does not want to advertise :).

Best not to use it then.
