Hi, hopefully someone could help me by shedding some light on a pc issue I have, I'll try to be brief....

ASUS M4N68t-M le V2 motherboard - 2.5 yrs old

AMD Phenom 2 x2 555 proc 3200MHz - 2.5 yrs old

Nvidia graphics - 2.5 yrs old

Seagate Barracuda 7200.10 500gb hd - 7 yrs old

Power supply - 2.5 yrs old

No optical drive

Grub2 dual boot Win 7 (50 gb) and Debian 7.4 (70 gb) - very recent installs with no issues.

Over the last few weeks I've noticed the bios screen being erratic, sometimes it doesn't show or appears only for a second or so, and other times shows longer than it's usual few seconds - I'm not sure if this is related to the problem.

The other day I reformatted the hd and reinstalled Windows and Linux. Yesterday I made a bootable usb of Vector Linux with PowerISO (Rufus wouldn't do it), and re-booted the pc with it in, the bios screen flashed on for an instant and the pc went into a 10 second loop - Num lock boot light flashes, then the 3 keyboard lights together, then Num lock again, ad infinitum...I've not seen the bios setup screen since. The pc has never beeped either.

I can get into the setup by continually pressing Delete on startup, but changing the boot order has no effect (The only way I can 'boot' something is by unplugging the Sata hd and running Rescatux or Hirens Boot from USB).

When I open 'EZ Flash 2', in setup, with the hd connected, it shows C:System Reserved, containing a Boot dir with lang dirs inside, and D: - D: has some of my Windows C: drive directories in it...so EZ Flash can, at least, read some of my disk.

I was thinking it might be a bios problem or the Sata disk had died, but now I'm really confused. Would the hd be readable in this way if it wasn't working? And, why, if the drive is OK, won't it boot?

Thanks in advance.

Very well could be a HD starting to die, if it has bad sectors info will be lost and the system will not boot or freeze. The best way to check it would be to pull the HD and test if with the manufacturers software run from the other system (all manufacturers have free checking software on their web sight) several do have software that you can download and run from a CD or USB drive on the system the HD is installed on by booting to the CD or USB.
