Response ends. Help please

Hi i'm new that forum. Thakns for your posts already.

My system info is like that:
MB: Gigabyte GA-8SG800
CPU: Intel Pentium 4 (Northwood) 2.4 GHz
VGA: ATI Radeon X1650 AVIVO AGP 8x
RAM: 1,5 GB DDR 333 MHz
AUD: Creative Audigy Value 24 Bit

My system has eaten 3 power supplies and a HDD. The HDD burned. I mean really burned!
Now when copying pasting some files from somewhere to another, my computer stops responding. I can't close the browser (ie, total commander, etc.). Some time later then, computer completely stops responding. The only way i can do is reset when this occurs. Anyway, after reset, computer works more slowly when exploring folders.

Also yeterday i was playing a game, but suddenly computer reset itself. It was interestring that the message shown when booting. I've never seen this Bios Post Message before, and that was the last. It was like that:

"The 80 pin Ide cable coneccted."

Thank you again.
Have a good day/night/whatever...

Note: HDDs are new.
IDE cables are new.
HDDs get really high temperature
