Hi folks, any suggestions for dealing with the following would be greatly appreciated:
I have a Dell Dimsneion desktop running Windows XP pro 2002, SP3, with Intel Core2 Quad CPU and 2 GB RAM. Total free space on the hard drive is at 80% (373 GB).
Last week while working on the PC, switching between MS Outlook, MS Word and Mozilla Firefox windows, I noticed letters and then entire words missing from the screen. This got progressively worse until I could see no letters at all and only images remaiing on any web page. I thought this might be a virus so I decided to save what I had and shut everything down. Saving proved impossible because I got a pop-up system message stating “Error: Insufficient system resources exist to complete the requested service” each time I tried to save my document and unfinished emails.
I shut down manually, then rebooted and scanned with Avast and MBAM - no threat showed up at all. I ran CCleaner and Puran Defrag and rebooted. After that all was well until today, when the same shenanigans started again. Again, no threat detected with the scanners.
I have found on some on-line forums that this was an occasional problem with XP SP2 a few years ago, and apparently until a patch was released it could recur every 2 to 10 days.
I did not have anything open that would cause a big draw on memory; I have in the past been able to run several bigger programs at once without issue (e.g. AutoCad, Google Earth, and Photoshop plus MS Office programmes could run together very happily once upon a time), so why does it happen now when I only have a web browser, word doc and emails open?
I’d be obliged if anyone can help me identify what actually causes this and how I might avoid it happening again. Thanks everyone.
