Hi all, We've got a well maintained p4 2.4ghz system with 512mb of ram and an 80 gb hd running xp pro sp1 with all updates that are possible without going to sp2 and for no apparent reason while on the web, the pc scrren will go black with a message requiring us to cold boot the pc to get it running again. I'm looking at the issue but would appreciate any tips. I have not yet looked at the recovery process to see if the system is shutting down or attempting to shut down rather than doing some auto recovery. Thanks!
