Hi, I recently purchased a new computer right before Christmas from Dell. The first several weeks, it worked flawlessly. Lately, however it has been freezing at least once if not twice or more a day. CRTL+DEL does not work, and the only way to fix this is to restart the computer. The other problem that I've been having is that the mouse just disappears. I have to unplug it, and then plug it back in twice in order for Windows to recognize it again. It is a standard USB mouse that came with the computer. The system is as follows: Core2Duo E6700 4GB RAM Windows XP SP2 I recently installed Windows One Care appx. two weeks ago. My computer updates as needed on an automatic basis. These are the only things that I could think of that have been added/updated recently. I use Adobe CS2, Lightroom, Quickbooks and Microsoft Office (as well as Mozilla Firefox for Internet Browsing) on a daily basis. I do not run any messaging programs or Norton. I use my computer everyday and cannot stand to keep losing my work due to this. Any thoughts or solutions would be greatly appreciated!
