Boot error, unknown origin, ideas to make this computer boot?

@gregrocker, ok thanks which exactly are the hardware tests?

Use Memtest86+ to Test RAM for 5-6 passes, and HD Maker's HD Diagnostic Extended CD scan followed by Disk Check from System Recovery Options Command Line.

Hmm, okay bit of an update.

I tried to run the mem test, it ran for a good few hours so that rules of the power supply being the problem. Showed 4 errors I think it was, I changed to ram to a different slot and blew the dust out etc. This seemed to make the installation run longer, but still crashed after copying files. I don't know if this is perhaps due to the computer not being able to restart itself? As it restarts after copying files when installing on a different computer?

The chkdsk check, just crashes the computer as soon as I run it?

Any ideas?

Check for a newer BIOS update on the computer or mobo maker's Support Downloads webpage. If none, Reset the BIOS to defaults: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS

Run the HD maker's HD Diagnostic extended CD scan to see if it will repair enough to run Disk Check from Command Line on DVD System Recovery Options. You can also Check File System (same thing) using free Partition Wizard bootable CD which is the most important tool we use here.

You also need to run the memtest enough to know if the problem is with sticks or slots. The tutorial shows you how.

You may need to clear the boot sector of code using Diskpart Clean Command
from DVD using DISKPART At PC Startup
