Here is some of the page info, to read the rest go here XP Dell Dimension 2400 Physical Memory Dump Error
I worked on a dell dimension 2400 that had lost the onboard video, Start Menu, Task Bar, internet and it only had PCI slots no AGP or PCI express slots. I work on family and friends computers for free, so I looked around the basement and came up with an old PCI 3dfx Voodoo 3 card, I really wondered if XP the OS on the computer would even have drivers for it. I put it in the number one PCI slot, that slot is always reserved for a video card and hooked the monitor cable to it and it worked. I tried booting the computer and was able to get into the BIOS. I was going to disable the onboard video but it only gave me the option for Auto or Onboard, so it got set to Auto. So now I had a monitor to see what was going on with the computer. The owner said she had no Start Menu or Task Bar and could not get online, that she kept getting error messages, the first one I got was a IPmon.exe error message. I did a search on Google and most sites indicated it was a malicious Trojan. I rebooted into Safe Mode and download Malwarebytes on my flash drive and then dragged it onto the wounded computers Desktop. It installed but gave a message error when I tried to open it.
