Hi All; In a recent clean install of Windows XP SP2 Home Edition after a month I am seeing in Event Viewer, System- 8 instances of Application Popup: MachineCheck: alternating with MachineCheck: Regs This is from a cold boot. If I pause in the BIOS it does not occur, nor if I restart. It starts first at say 1:37:35PM and all 8 are at the same time. The Event Log is reported starting at 1:37:45PM and the remainder is normal. It does not seem to cause any problems. I have searched here before posting, and other forums with no helpful solution. It is Event ID 26 and the Microsoft Help and Support Center states the error is a driver problem. I have not added any devices, or made changes that I am aware of, and as I said, all is running normally. I certainly would like to stop it and hope that someone has an answer. Thanks in advance for any help. Roger a.k.a. Hikerbear PS I'm shown as logged in, but when I preview I get a msg that says I am not logged in. Howcome?
