Recently I have been having problems with this computer that has led me to believe my video card failed. I ordered and replaced the system board and when I booted it up for the first time I discovered I still had the same issue that I began with, so I began to suspect a corrupted operating system. Every time I booted up I received an error message that referred to a winXP SP3 disk that I have never had, and I couldn't seem to download any new drivers or reinstall SP3 at all. In fact, the add/remove programs menu wouldn't even give me the option to remove SP3. After various troubleshooting efforts, I decided to perform a system restore to the earliest point I could find. The computer took a long time to shut down and I had to go to work before it finished. When I returned home I tried to turn the computer on and all it will do is have the power LED come on. Nothing comes on the screen, no activity occurs or anything. I take that back. With the Dell-supplied windows CD in the drive, the drive appears to try to access the CD, but then stops and nothing happens. If I don't shut the computer down, it will eventually start getting hot as if it were being used heavily. I have not gone back into the computer to check physical connections since it was working just fine before the system restore. Also, I had a full charge on the battery so I know the process wasn't interrupted during the restore process, at least not due to a power failure.
Any ideas on how I can get this machine running again?
