If after virus scans and other attempts at repairing, I'd just wipe the system and reinstall OS if you can. Good luck!
It occurs due an unhandled exception of Operating System. It may be due to a multiple reasons usually some virus of malware.
change your RAM position and than repair your window make sure a antivirus for your system when you use after repairing the window.
Well some time it hangs because of virus presence in system and another reason may be there is some logical error in hard drive. Some time it start to hang and then blue screen, some words like that "system recoverd from serious....." type message. It is hard drive error.
It can be due to a malware present in your system...You need to check it and system generally hangs due to the position of RAM as I was facing the same issue the other day...So do not take chances and get it repaired asap...!!
It can be due to so many reasons like malware/virus, recently installed non compatible or corrupted soft-wares/drivers, missing files and dusting is also a big problem for the Dump Screen(Blue Screen) and many more reasons... You need to troubleshoot the problem one by one...
Clean your ram sticks very easy to do first hold the inside of your computer case to ground off yourself turn off the computer remove the ram use your saliva (spit) on a cloth and wipe the gold metal part until clean pass the dry part of the cloth on it to remove any wetness put it back into your computer watch your computer work from there
It's not a good idea to use saliva to clean ram (or anything else in your computer). It's also very funny that everyone starts suggesting something and nobody thinks about asking the OP to give more information. "My computer sometime is hang and create blue screen. but why?" is not something someone can work with. All we know is that he might be using some sort of windows OS. Some basic information is generally needed, else every suggestion is just guessing. Also: then BSOD happens for a reason. You ever tried to READ what's on the bluescreen? You should, because there is an error code, which can help you resolve your problem.
check it out for viruses install the fresh operating system also check out either your system is heating or not
