My computer keeps freezing

[computer1337]

Hello guys, I have been strugling with this problem for about 6 months now and I really cant stand this anymore. My pc freezes at random times, may it be when i turn on my pc or maybe when its idle or when im on it, my point is it is random. So I had a computer guy come over and check it for me. After 2 hours of checking all the hardware he said nothing is wrong with the hardware, and so he proceeded to blaming it on the software. Now this is where things get tricky, he told me that it was my out of date bios drivers. So we updated that and well the problem was gone for the day, or was I lucky. But it still is a problem I encounter daily. Please people help me because I am hopeless at the moment :/ Anything I can install to check for crash reports? Basically the freezing is like this that mostly everything stops working, I can move my mouse around for most of the time but everything is frozen, music pauses and plays randomly and well it unfreezes after 10 or so seconds and keeps doing this for about 2 minutes at random times and then everything comes back to normal. I got a asus z87-c motherboard, 8gb ram, geforce gtx 760 windforce and a power supply of 1000Watts.
So I also check event logs and I have stumbled upon this error:
Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected.

Could this be the cause of these freezes and stuff? If yes how can I fix it, considering without reinstalling windows ??

This problem is generally caused if you use the removewat crack for non genuine windows. If you're using it, you know what to do. Else replace removes at with windows loader crack. Google it.
The second cause can be RAM. This will be the problem if your PC is old and you tried to install a software or basically an OS that your RAM cannot sustain.
Thirdly, delete malicious non trustworthy softwares. They run certain progrs in the background which increases load on your CPU, hence causing the system to freeze.
