Hi and welcome to SF

Usual causes: Insufficient disk space, Device driver, Video card, BIOS, Breakpoint with no debugger attached, Hardware incompatibility, Faulty system service, Memory, 3rd party remote control,
Are you using Mcafee antivirus software? If so, please remove it completely, then install MIcrosoft Security Essential Instead to protect your computer. The reason is simple, third party AV is known for causing BSOD in some system and the symptom you describe is possible that Mcafee cause it, as the system run it when you activate the computer from sleeping <--Uninstall Instruction <---MSE

Update these drivers:
