I've been getting the machine go unresponsive for long periods of time and lately lock up hard with the circular cursor. I installed the MS hotfix for the interrupt lockup and that seems to help, and I found the thread on "Windows freezes periodically with protection on" and followed the advice and disabled things till the lockups seemed to go away, but HIPS, the ESET firewall and auto start of real time protection are down. I'm running with minimal protections currently. ESET's firewall was already off because I have a hardware firewall and cannot play World of Warcraft with ESET's firewall even with a rule allowing wow.exe (it helps to have the rule but doesnt fix the massive lag spike issues). MS Firewall seems to be ok once you add the rule for wow.exe. So I guess my question is are there any other options besides hoping MS fixes things?
