I have a machine with Penti 4 and 512 ram. It is an HP-E-PC and every few hours it has a Stop error 0X0000008E on the blue screen of death and it has to be rebooted. No new hardware or software has been added. There is no information in Event Viewer and all the diags have been run. The hard drive has been taken out and put in a new system and it still has this issue. Any assistance you could offer would be great.
