Hi and welcome to SF
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
