A few months ago, I encountered a system freeze and had major troubles getting into Windows 7 again. Once I did, I tried Prime 95, Samsung ES Tool and Memtest86, which all came up fine.
After another month or so, the system freeze happened again and I had a problem where I could get into Windows and move the mouse, but when I did, I got the following blue highlight below:
I was able to use the keyboard and move the mouse, but wasn't able to load up anything with the mouse, the L/R/M buttons had no effect. I couldn't get rid of the problem, so re-installed Windows and all was fine until last night, when playing a flash game (Firefox 4), the system froze again and the same problems happened again, even in safe mode, nothing worked until I repaired Windows from the installation disc and it's all good again.
I've run ES Tool again and this passed, so the hard drive seems fine. I've also run Spybot and a few Chrome/IE entries were found and deleted. I also ran an Avast scan with no problems.
I'm not sure if this is a hardware/Windows problem and would appreciate any help.
