I keep all my drivers up to date. My m/b is Foxconn P9657AB-8EKRS2H. I know it's an old board but have you heard of any problems like this? So far I've checked for problems with everything I can think of: drives, cables, power, cards, RAM, ventilation, drivers, programs.
I just thought of something: I have my old rig set up elsewhere. I'll be out there in a couple of weeks. I'll see if I can make them work on it. If not, then 86. Like I said it's more a curiosity.
