Hello, I get bluescreen many times when I shut down my computer and I thought that somebody can help me.... It's not a rule but its annoing. Firstly I thought that it was because of overheating of some of my pc components because this error seems to appear when I use the computer for many hours.... I tried to play some games and to shut it down but the error didn't appeared.... Secondly, I tried to play games untill it was hot, than I left it a few minutes untill it cooled down and I shut it down and the error appeared again.. So I don't think it is because of the heat... Firstly, this error appeared just by shutting down of the computer, but in time it also appeared also while surfing the web, while playing, while killing an application, when putting on sleep or when shutting down... (when shutting or putting on sleep down lets say 1 in 5 times, the monitor goes black and the coputer stays open...) It appears more frequently when shutting down or putting on sleep... I checked the computer and it doesn't have dust in it and the drivers are up to date.... Now the last thing that I suspect is the software... (and I really hope that this is the problem ) My computer is a DELL PRECISION T5500, hex core processor XEON 5675, video card: Quadro 4000, 12GB RAM ECC, 1.5 TB HDD and Im running Windows 7-64 bit I have deamon tools indtalled and eset smart security system AV. (heared this may cause the problem but not sure...) As You can observe from the minidump files its not so stressfull and frequently that I cannot work on play on it but I would like to know what to do because my warranty wont last forever... Please help me.... I don't have other options and its really hard to ship it back to the warranty because it'll cost much... I'll upload all the minidump files below.. there are a few and pretty various... BSOD.rar Thank You very much!
