After 4 years of owning a Dell Dimension 8100 I came into the computer this morning and noticed that I had received the above titled subject line. *** Hardware Malfunction *** NMI - Parity Check / Memory Parity Error The system has halted.

Being that this was the first time anything like this has ever happened to my little box I wanted to go ahead and find a proggie to check my modules since I guess one or two of the modules are either going bad or something is wrong. Does any one know of a good testing or diagnostic program to test your rdram or might you have another idea for me to check? Maybe reseat all the modules and or check to see if they are in good enough?

The only think that I have done internally the last few month is about  4 months ago install the powerleap and a 2.4 processor...

Thanks...
