BSOD problem, to do with ntoskrnl.exe

Hi,

I am new to this forum and am not very computer savvy. I started having problems with BSOD on my PC last week. It became so frequent that I decided to backup my files and do a system restore in hopes that this would get rid of the problem.

This was not the case however and I am still having BSOD problems, at first I had this problem when running multiple applications, like having mozilla and skype open at the same time, but if I leave my PC on longer the crashes become more frequent, so that even opening up mozilla or chrome can cause it to crash.

I ran a bluescreen viewer report after a couple of the crashes and each time it showed that the problem was with ntoskrnl.exeI've attached the SF diagnostics file. I'd be grateful for any help or advice.

I am also having problems with doing windows updates, everytime I try it says that configuration has failed, not sure if this is related or a different issue.

   Tip

• Pay close attention to part 3 of the tutorial "If you have errors"
• Test the RAM with Memtest86+ for at least 7-10 passes. It may take up to 22 passes to find problems. Make sure to run it once after the system has been on for a few hours and is warm, and then also run it again when the system has been off for a few hours and is cold.

Monitor hardware temperature with system monitoring software like Speccy or HWMonitor:
