Hi there, I am new to this, but as I was searching for an answer to my (similar) problem I came across this page and I am hoping that you may be able to help me...
My computer is also freezing on me, periodically, and I have no idea why.
The only new thing which I had done to it recently before the freezing began, was to install, then immediately roll-back from, Windows Media Player 11. I have done this half successfully- I now have Windows Media Player 10 in use, but the Windows Media Format 11 Runtime cannot uninstall as the folders required to do so have been deleted. But I don't think this is the problem.
Right, onto where you come in... you mentioned a "brown out" and whether or not Yield22 had had one, well I HAVE!! I came home from being away for a couple of weeks, and we were currently experiencing a brown out, but as I'd been away for a while, and wasn't 'used' to the lighting back at home, it just seemed a little odd, but I thought nothing of it and went ahead and booted up my PC... but alas! It kept restarting itself constantly sometimes getting to the stage where I would enter my password to get into Windows, most of the time not making it past the flash screen with all the BIOS info etc... This went on for a good hour to 2 hours, until eventually there was a sort of power 'surge' if you like and normal power was resumed. The PC then kicked into life and booted up, and promptly froze, nothing worked at all, mouse and keyboard all gone, nothing but a hard reset would do. Since then, every time the computer is on, it will randomly freeze, doing anything from web browsing to listening to music, to just typing in word. Quite often it will freeze very quickly after being booted, but it can do it at any time. Sometimes it will remain fine for upto 2 hours, but far too frequently it just freezes.
I have looked at it being a thermal problem, but all temps are fine, there are two large fans in the CPU and they are both working well.
Any help would be hugely appreciated, I really need my PC up and running again. Any info you need, just let me know and I will happily provide it.
Thank you for any help big or small,
