Memory can actually hard lock a system? I thought it would usually cause a panic. At least some of the time. That's probably not a bad idea, but I gave up on the system and got another one. The new system is identical. I just pulled the hard drive out and plopped it in. This one runs fine, so there was some kind of hardware issue. I tried reseating everything but the old one would still hard lock. Just out of curiosity, have you seen a system where memory would consistently (within a short time period) hard lock it? Not just in memtest, but in Linux. Anyway, I definitely appreciate everyone's help and I get to eat humble pie about my KVM complaints. <> Jim > -----Original Message----- > >Thanks for all your help.
