i have a p4 3.2. lately it has been rebooting on its own. when it restarts i get a window that says it cant find drvkej.dll, i cant find anything about this dll. then another window pops up and says that windows recovered from a serious error. when i tell it to send report it tells me that my video drive caused the reboot. i have updated the driver. that did not work so right now i have installed the driver put still have reboot problems and it still says video driver problem. and when i close the window out it pops up again. i cant get rid of it. i have run avg, have zonealarm. ad-aware,spy bot,Prevx1,windows defender, and maybe 1 or 2 other things. o and hjt. and i still have rebooting problems. some times every 5 min other time a day or so. so far nothing has worked. some help would be grateful. thank you.
