Recently in the past couple of weeks my computer has been freezing at random internals with absolutely no warning or prompting at all. It's not a case of me opening a specific program, or making it perform memory-intensive tasks -it will just completely freeze up out of the blue. This morning, all I did was turn it on and by the time I came back from making my cup of tea it had frozen itself. The other day I was typing a sentence onto a word document with no other programs open and it froze. The entire laptop becomes unresponsive -the capslock key doesn't respond, although interestingly enough my graphics tablet seemed to still be responsive (the lights would change colour like normal when I use my pen on it). The only option I have is to do a hard reboot.
This has been happening intermittently for the past couple of months (perhaps starting around June?), but it's only recently starting to get worse. Before it happened once a week, and now it's starting to happen about once a day. I've run a virus check, registry clean and deleted some of my most recently installed programs but neither of them have helped.
The computer runs fine otherwise -no excessive slowing down, no crashing programs... it's rather frustrating because I find it impossible to isolate the problem. Any help would be much appreciated!
