Hi.

It all started from computer restarting itself. It first I thought it was CMOS battery that was causing it because the system time was all the time wrong. I changed the CMOS battery and all I got was fixed system time but the restarts remained.
My mate told me that I might have some problems with HDD. So following his advice I ran checkdisk on the faulty HDD and during the 40 minute process it remapped like 5 bad sectors and on the fifth step: "verifying free space" it just fails. (Video below) After that I have to restart and the whole checkdisk thing goes on again. It's like a loop. (My PC still restarted if I managed to get to windows)

So what are your suggestions? I need urgently HELP!Test hard drive with manufacturer's diagnostic tools:  http://www.tacktech.com/display.cfm?ttid=287Okay. So I went to that webpage and downloaded the bootable ISO file. (It was the only thing I could choose because my computer does not have a floppy drive.) I followed every instruction, I burnt a bootable CD which worked fine in my computer, but it didn't WORK in the broken computer. It spun the CD in the cd drive but nothing happened. So I decided to swap HDDs so I could boot the CD in my computer and then CHECK the HDD I needed to.

But here's the problem:

What else can I do?Don't know why the bootable CD didn't work in only one of the computers.  Maybe you didn't set Boot Order to CD 1st?
Your good computer doesn't have an IDE (PATA) port?
I ALREADY got it and ran Seagate tools on that broken HDD. even seagate tools failed an important diagnostics test and it found like 100 bad spots while performing a long test.
