[I] started prime 95 and right away workers 1 & 4 quit with "hardware failure detected" the others workers 2 & 3 are still going as I am typeing this. Could someone explain what workers are and why only 2 of them quit?

actual error was "FATAL ERROR: rounding was 0.5, expected less then 0.4"

Actually if one quits nothing on the computer has quit but something needs more juice (voltage).

thanks for the reply would it be the CPU or one fo the bridges? Whats your best guess?

my best guess is u need to check it out u're self and the best way to do that is by increasing 1 thing at a time until u find what u're board and processor needs. let me tell u, u can burn things up real fast by giving it too much voltage. even increasing by a little makes the life shorter. I am running a ASUS board that eats mem by the month and all I have increased is the northbridge.
