Start by doing the following so we can rule out malware.

Are all drivers up to date? How old is this machine.


Please download Malwarebytes' Anti-Malware from here or here and save it to your desktop.
  • Double-click mbam-setup.exe and follow the prompts to install the program.
  • At the end, be sure a checkmark is placed next to
    • Update Malwarebytes' Anti-Malware
    • and Launch Malwarebytes' Anti-Malware
  • then click Finish.
  • If an update is found, it will download and install the latest version. Please keep updating until it says you have the latest version.
  • Once the program has loaded, select Perform quick scan, then click Scan.
  • When the scan is complete, click OK, then Show Results to view the results.
  • Be sure that everything is checked, and click Remove Selected.
  • A log will be saved automatically which you can access by clicking on the Logs tab within Malwarebytes' Anti-Malware

If for some reason Malwarebytes will not install or run please download and run Rkill.scr, Rkill.exe, or Rkill.com but DO NOT reboot the system and then try installing or running Malwarebytes. If Rkill (which is a black box) appears and then disappears right away or you get a message saying rkill is infected, keep trying to run rkill until it over powers the infection and temporarily kills it. Once a log appears on the screen, you can try running malwarebytes or downloading other programs.



Download the HijackThis installer from here.
Run the installer and choose Install, indicating that you accept the licence agreement. The installer will place a shortcut on your desktop and launch HijackThis.

Click Do a system scan and save a logfile

Most of what HijackThis lists will be harmless or even essential, don't fix anything yet.

Post the logfile that HijackThis produces along with the Malwarebytes Anti-Malware log
 
As you requested, here is the log files.

Ok, it doesn't seem like its malware related. Are all drivers up to date? One of the blue screens were caused by your antikeylogging software called keyscrambler.
 
sorry for the late reply john. Yes thats right, one of the errors was caused by the key logging software which has now been removed. I also ran disk check which has really calmed the random shut off's down. Now this is gonna sound real stupid: what is the best way to update the drivers and which drivers do I update? Is there a program around that will update drivers like the program secunia? Thanks for the help so far.
 
Is this a store bought or custom built computer? You should go to the manufacturers website to get the correct drivers. If custom built, I would need the make and model of motherboard. If store bought, would need model number.
 
Thanks for your help so far buddy. I thought I should as precaution run memtest and it turns out the the memory has some 1000 errors. So looks like the culprit has been found. I shall update.
