Dell Dimension B110(purchased approx. 7/2006)
Pentium 4 Celeron Processor(2.53Ghz)
512 MB RAM
D-Link Wireless Router
1. About 2 weeks ago I had been running an antivirus software on my C drive and when the software finished scanning the hard drive it asked me if I wanted to scan the memory which I chose to do and retired for the evening. Don't know if the scan had anything to do with the subsequent problems but thought I'd mention it as that immediately preceeded what came next.
2. The next morning I found a black screen and a black screen when I rebooted. Coincidentally, we had a Comcast cable technician coming to the house that day to inspect/replace our cable modem we'd had problems with and he volunteered to look at my computer. After looking at it he recommended that I reformat the hard drive and reinstall the Windows XP Pro OS. I did this and was able to reboot successfully and bring the PC back to its desktop BUT with continuing problems.
3. I can successfully log on to the internet but at dialup or slower speeds
4. Anything on the screen appears as though it's being viewed through a magnifying glass. Attempts to go to Control Panel-->Display-->Settings and increase the screen resolution setting failed as the little ticker that you move to the right WILL NOT move at all. Color Quality is also stuck at 16 bits.
5. So I went to look at my processor performance and using Control/Alt/ Delete brought up my Windows Task Manager and clicked the performance tab and found out the CPU is pegged at 100%. Ordinarily, it would be in the 8-10% range.
6. So I thought my memory might be corrupted or damaged in some way and after indentifying the appropriate type, I replaced the memory with a new 512 MB RAM stick. The CPU usage is still pegged at 100% and the resoution settings are inoperable.
7. Next I thought maybe my CPU is overheating and causing the problem so I downloaded some software that monitors fan speed and temperature. CPU temp is 33C.
8. So that's where I am right now. By virtue of the process of elimination, it seems to be down to either the processor or the motherboard. Seems to this layperson/amateur that if the motherboard was damaged I couldn't access the internet even at the glacial speeds I'm able to now. I've had a mobo crash before and that computer wouldn't do anything.
9. Am I missing anything here? Is there something else I should have done or checked? Please help my pitifully sick computer.
