Hi. I have a compaq evo n1020V, Windows XP pro, Sp3, 1gb RAM My computer restarts itself. I wouldnt say it is random though. Prior to today i wouldve said it only happens at certain times. It happens mainly if i'm watching a DVD and am moving between chapters etc. Its also happened the other day when i added a facebook interactive program. It does seem to be related with video/graphics. However I thought to myself i will re-install the OS. So i got my XP disk and used it to start up from so i could repair install. However it didnt even get to the menu screen. it just restarted itseld again. This kinda told me it might be a DVD drive fault but then i remembered it happened in facebook and the drive wasnt even being used.! Anyways..i ran AVG, adaawre,regcure..all that..still problem. So after it restarts i have to take out all cd/dvds and any usb devices otherwise the ...LAst good config..start windows normally screen appears ...if i dont remove devices the computer will continue to say this screen and not start up. I've run Diagnostics for windows in control panel.....all clear. re-installed all the latest drivers from compaq website. I am lost.....anyone help????..Is it a buggered video/graphics card...I have run VideoCardStabilityTest and it crashes. Is there anyway i can know for sure the video/graphics is working or not? Cheers guys !
