PSINAflt.sys is part of Panda Cloud AV. If I remove PCAV and put the computer to sleep, when I wake it up, everything is fine. With it installed, it will get the BSOD very quickly after waking. If I set PCAV to not scan just before I put it to sleep, then when I wake it up (and turn scanning back on), the OS will limp along with odd errors here and there until eventually it gets a BSOD. If I log out before putting the computer to sleep, when I wake it up and try to log in, it will get a BSOD almost immediatly. I'm fairly certain PCAV is the problem.
In the PCAV forum there are countless threads on PSINAflt.sys causing BSODs though none are related to waking. I will post a thread there and see where that goes. When I know something I will update this thread with what I find.
I find it odd that it worked fine with the old CPU? I think I will also swap out the CPUs again and see if the problem persists.
As part of my testing I uninstalled PCAV and reinstalled several times using the absolute latest copy possible (that is not in beta).
While I wait for a response in the PCAV forum, I will run memtest from an Ubuntu 10.10 live CD. I expect to find no errors at all, but you never know.
I really don't want to lose PCAV (in favor of something like MSEssentials). If that seems odd, take a look at PC Magazines review of the best free AV products (not sure if I can post a link here, so just google that).
