Hi there all. First post so I immensely appreciate any help you can give :) I've looked for the solution on other answered posts, but no luck.

I thought after being on PCs for 23 years and owning many I would know what to do here, but I'm totally stumped. I'm getting a BSOD computer reset everyday for the past two weeks (if I can recall). It usually happens once or twice a day after a long day of having the laptop on, and usually right at a very inopportune moment such as working on music/doing University work etc. I've owned the laptop for about 5 months and had no issues before this. I could usually leave it on for days at a time and it would never shutdown.

I was concerned it was maybe an overloaded memory problem, because sometimes I would run Google Chrome and the memory usage would sometimes spiral out of control, and I would also usually be using VLC Player and other things as well. I ran a few memory tests and it doesn't appear to be affecting anything.

I was then thinking that maybe the laptop was overheating in it's current position, so I elevated the area where the fans are and had a portable fan running underneath it to cool it down. It made no difference.
I also want to point out the BSOD can happen when I'm not even running anything, all browsers closed down and me not even touching the laptop.

So I found Bluescreen Viewer and ran that. The highlighted issues that are causing the BSODs are ntoskrnl.exe and PCTSD64.sys. I knew what PCTSD4.sys was, so I completely erased PC Tools Spyware Doctor to see if that helped. I cannot find a way to fix ntoskrnl.exe through Googling, I'm completely stuck. According to the net I should run Driver Verifier so I did and it was causing a BSOD on bootup, but I do not know which driver it is that is faulty.

System Specs:
Alienware M17x Windows 7 Home Premium x64 OEM (OS came preinstalled. 5 month old system)
Intel Core i7-2630QM @2.00Ghz 2.00Ghz
RAM: 6gb

Attached Zip File.
Thank you for your help.

Hi,
Thanks for getting back to me. Like I mentioned, I had already removed all traces of PC Tools after that last minidump. I have now installed Microsoft Security Essentials like you instructed. Looks like a nice little spyware program without the need for PC Tools anymore.
What can I do next?
Thanks

I've given it a few days and since deleting PC Tools I haven't had a single problem so far. So thank you for confirming that PC Tools was definitely at fault here, and thanks for recommending Security Essentials. It looks like a decent program and I wasn't really that keen on PC Tools anyway.

Merry Xmas.
