This is regarding an old Dell Dimension 8200 PC with 512MB RAM, Pentium 4 processor, 1.5Ghz speed, 40GB Hard Drive with Windows XP Pro SP3. It was running great up till a few months ago when, one night, (whilst the computer had been shut down but stilled plugged in to the mains as per usual) something inside went bang and there may have been some smoke. Ever since, the computer boots up to the desktop screen, portions of which are distorted and pixellated, and eventually stalls.
I connected it to a different monitor and power supply to see if it made a difference.
The results can be seen here:
Obviously this is not my main PC but it would be nice to have it running again.
So I would be grateful for any and all advise to fix it back to full health.
