Newly built computer, installation went well, no problems. Once the computer has been boot up into windows, it is only a matter of time (maybe 5-10 minutes MAX) before the computer locks up. It has even done it before I logged in. It's a hard lock, I can't ctrl alt del or anything like that. Frozen pointer. Only way out is a hard reset. Your expertise is greatly appreciated. EDIT: Safe mode does not hang (with networking, has been on for at least an hour now and no hang) I believe the error is from "DistributedCOM" of event ID 10005 although I'm not sure There are many errors in my event list, mostly duplicates though.
