Hi there, I have in my possession a Dell Dimension E520. I had an older computer with a hard drive/operating system on it and I moved it over to the new computer. I thought I had done this succesfully, I had uninstalled all of the original drivers, reinstalled all of the new chipset, graphics, audio, etc.. And I even ran the Windows XP repair program from the original install disk. The computer itself runs just fine with no problems, aside from the random crashing that occurs. I have had many different blue screen errors, and every single time we get one, we address the problem, but it's always a different error. I can post some of the screen shots when more of them happen. I know you're always supposed to do a clean install of windows and all that for a new computer, but this computer is a pharmacy workstation and there are loads of confidential files that need to be preserved and CANNOT be lost. It is very important that this computer gets running normally. Any help would be VERY MUCH appreciated!

If you get many different random errors you might have bad memory. Test it with something like Memtest86.
I've ran Memtest86 many times before and every single time I ran it, it cleared and passed without any problems.
