After this I put the hdd in this computer ran norton to see if any viruses we're infecting it, there were 3 which I wiped off and since reinstalling windows the computer started but froze while detecting the Hdd and Cdd's.
So, I tried the hdd, sound card, eithernet card and graphics card all worked, all worked in mine, and all worked in his expect the graphics card.
Completly lost at what is and whats not working.
