I have built several PCs for family, friends and myself and i just finished a small work station for my den. However it seems to be having a grounding problem that i have not been able to pin point.
I bench tested all hardware before i put it into the case. Motherboard, CPU, Hard drive, PSU, DVD all worked 100% and i installed windows 7 pro 64 bit . I put everything into the case and attached 3 addition hard drives and 2 fans as well as the case USB and Audio. I have checked for misplaced mounting posts, as well as all the connections to everything on the motherboard and components. I can't see anything that would be grounding the mother board.
I have taken everything out of the case, retested, and reinstalled and it still is being grounded somewhere.
I am using an Antec 300 case, MSI Micro ATX Motherboard.
Any ideas suggestions would be great, i am fresh out and this is DRIVING ME CRAZY!
