Reinstalling SP3 has seemed to of resolved the initial issue. I once again got at startup "hard disk failure is immanent. Back up all your data."
Event viewer does not look to clever
All fans are running and MBAM come back negative.
Okay, you say you "once again" get this message but this is the first mention of the HD issue in this thread. Again, check your connections inside the box to and from the HD - you might have knocked a connection loose. Otherwise, it appears that your hd is about to fail and you need to backup all critical data immediately
You can then run hd diagnostics, but I'd be prepared to replace it:
Hard Drive Diagnostics:http://www.tacktech.com/display.cfm?ttid=287
Make sure, you select tool, which is appropriate for the brand of your hard drive.
Depending on the program, it'll create bootable floppy, or bootable CD.
If downloaded file is of .iso
type, use ImgBurn
to burn .iso
file to a CD (select "Write image file to disc" option), to make the CD bootable.
