Great News...
I finally got the games working( at least for now) :)
Here's what i did:
- I've got 2 cd-rom (CDR and DVDrom), they were both connected to the PSU by the same wire that supplied the power to the 9500 pro fan, i removed those wires from the cdrom's and leave it only supplying power to the 9500 pro fan. The games stopped freezing, i played MOHAA, UT2003 and Halo and the PC it's goin' fine at about 2 hours... i'm a happy man lol
Give it a try if you're having probs and feed back...
Thx for all the help ppl, if something happens i will post again...
Cheers...
