Having trouble with my PC: running very slow and hot!

 

Two days ago I received a BSOD message ("IRQL Not Less or Equal") and somehow got rid of it by trying different suggestions I found here on the internet (which one helped I do not know).
 
Unfortunately, following this incident (after BSOD issue is solved) my Sony Vaio is not the same. It became extremely slow (to a point that using it becomes nearly impossible) and running very hot. CPU spikes to 100 % nearly all the time, even with no programs running (when nothing runs svchost.exe is the one responsible for spikes). 
 
Steps I have already taken with no result:
 
- I use an antivirus programme and I ran an additional check up
- I ran msconfig and disabled all the unnecessary programs running at start ups
- I updated all my drivers
- I did a clean boot
 
No changes. Will be thankful for your suggestions!

It might be a good idea to boot to safe mode and see if you have that problem there, while your in safe mode run a full scan with Malwarebytes.

 

Safe mode how to: windows XP through 7: Power off the machine, after powering on tap F8 on your keyboard until the boot menu appears, use your arrow keys to select "safe mode with networking"


If I am helping you with a problem and I have not responded within 48 hours please send me a PM.

Thank you for your reply! I tested your suggestion and the problem is not there when I run my PC in safe mode. What does that mean? What is the next step from there. Huge thanks!

If it seems ok in safe mode then it is likely a software issue. The process svchost.exe is responsible for many things in the OS, the next step would be to run a full Malwarebytes scan in safe mode, you can download that here: http://www.malwarebytes.org/mwb-download/

Install Malwarebytes and run a "Full Scan" then let us know what it finds. If you have not already dusted out your computer this would be a good idea as well. Buy some canned air and blown through the intake and exhause (where the fan blows out air and pulls air in). A good working computer should be able to run at nearly 100% load without blue screening or overheating.
