Computer Locks Up for no apparent reason.
Posted on 2007-08-01
I have a Dell PC, Optiplex, P 2.8GHz, 2.0GB Ram, XP Pro SP2. In the last week or so, the computer has started to lock up for no apparent reason. I am not getting any kind of error message and I ran a test of the memory which showed no errors.
The only other "symptom" which happens frequently and I've never been able to get a diagnosis on is that for about 3 or 4 months, I noticed that whatever I happen to be working on, whatever application is "in focus", (this could be anything from OE or IE to notepad), the application will appear to "refresh". This happens about every 10 to 15 minutes. By "refresh", I mean you can see the dark blue of the title bar change to light blue, the cursor temporarily disappears and then it all comes back.
I have no idea why this started happening or how to fix it or if it is related to the lock ups I'm getting now. When the computer does lock up, I have no option but to power off and restart. The lock ups were happening about once ever couple days and today it happened twice in the span of about 6 hours.
Your help is greatly appreciated.
