HP 8660C - PIII600 freezes intermittantly. Totally random - has happened at various different times . The following items have been replaced or exchanged - memory ; hard drive ; added video card ; 2 different OS's - win 2000 pro and XP Pro. Not much left except the MB or CPU and neither of these seem to be readily available anymore. Someone said the HP's use a proprietary MB so I cannot install a regular ATX board. Any ideas other than to give it the "Office Space" treatment??
