My computer screen is freezing once a day or so without any BSODs whatsoever. The funny thing is that everything else is running in the background, including the system clock, music from WMP, and even a video game CD I popped in when it was frozen, which launched like normal, but was unable to do anything because the mouse and keyboard were unresponsive.
When it freezes, I hit the power button once and it shuts down like normal too. Even when I put the computer to sleep during the freeze, it wakes up normally and it works just fine again!
All my drivers
are up to date, so what can the problem be? I also tested the hardware with Dell Support Center tools and everything checks out fine.
Remember, everything else is running in the background just as it should, including the clock which still keeps time correctly. The screen looks fine too with everything being displayed clearly and crisply, with no artifacts or lines or anything.
I was also working on a paper for class when it froze, and the funny thing is that when I hit the power button to shut my pc down, it was prevented from doing so because MS Word itself was asking me if I wanted to save the document, which means other processes were running, but I couldn't save because the mouse and keyboard were frozen, so I had to hold the power button until it shut off. Luckily I didn't lose much progress at all because I saved it just a few minutes before. This is a really perplexing situation...
What can be the problem here?
Thanks for your help.
