Hi, I recently encountered a problem with my computer involving 'blue screen of death'. I realised this when everything was running smoothly, whilst playing World of Warcraft, my computer crashed and up came the blue screen. The first time it said something about drivers, so I assumed my drivers were a little rusty and tried to load the game up again. Five minutes into playing the same thing occured, but it said nothing about drivers. The third time it happened was after 30 minutes of not loading the game to see if it only had an effect on the game. I load it up and the blue screen appeared again, showing my thoughts were correct. When I re-booted a message appeared saying KernelDrv.exe has encountered a problem etc. I searched the name and came accross this thread. techspot.com/vb/topic97552 . ( Sorry won't allow links ) I followed the instructions, however nothing appeared in my task manager. I then found it in C:\windows\system32 and thought I'd cracked it so went on to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run, nothing appeared there so I ran a full Ad-Aware scan (as advised on the thread). Half way through the scan a message appeared saying KernelDrv.exe has encountered a problem and has stopped running...again. The scan deleted 2 critical items and I re-started the computer. As I knew the file seemed to only have an effect on World of Warcraft I loaded it straight away, with no luck the blue screen appeared again. Sorry for the length of the thread. As general information goes, the computer is well used and is roughly 6 years old. What should I do now the other instructions didn't work? Any replies appreciated.
