Windows 7 Constantly Reports Missing Files Which are Still There
Hi,
my computer for some reason has been behaving strangely. After format and reinstall, many of the windows features would not work, for example when I right click on "Computer" -> "Properties" and get to the System page, selecting "Remote Settings" "System Protection" or "Advanced System Settings" does not do anything.
it also prompts that many files are missing, it's immediately apparent when I try to eject a USB drive and i get the message that the hotplug.dll module is missing.
Here's a portion of the hijack this log:

The thing is, all the files are still there. Recently after clearing the BIOS and reinstalling, everything was perfectly normal. it stayed normal for about a month and now it's back to this state again. Sometimes my Network LAN card would stop working as well, had to reset BIOS to get it to work again. This is not the normal corrupt system files problem, I have never seen anything like this before, any ideas?
I have replaced the motherboard before, memtest (which was a prime suspect) was also cleared. could PSU cause such symptoms?
thank you
