My XP machine shuts down by itself after 1 or 2 minutes running. I replaced the Power Supply, cleaned the insides very well, and made sure the 2 fans were running ok. Next I removed the old hard drive and I am in the process of installing the xp operating system to a new hard drive. However I now cannot complete this task as the machine keeps shutting down before finishing. Strangely however the machine will run very well when I insert the Linux Ubuntu CD and run off it and it does not shutdown. It has been running for several hours now without any problems. I am at a loss as to what to try next so will appreciate any and all suggestions! Sincere Thanks: Richard

probably a motherboard failure - maybe faulty capacitor(s)

during windows setup the routine makes pretty heavy interrogation - and power - demands on the board, which could push it over the edge
Running a Linux "live" CD does not seem to cause the same problems

Its worth downloading memory test software such as this http://technet.microsoft.com/en-us/magazine/2008.09.utilityspotlight.aspx
just to eliminate memory errors, but its probably the motherboard

what make/model of board is it? what make of machine?

and just as a PS -- if it has a separate graphics card, make sure you eliminate that as a cause: try a different card, or run with the m/b onboard graphics instead
