Laptop Running In Slow Motion?

I've been having this problem recently with my laptop running in kind of like slow motion. The problem starts when it takes my laptop an extra long time to boot up and then afterwards my windows minimize and maximize very slowly and my games kind of run in slow motion. This happens 1 out of 10 reboots and a restart usually fixes the problem.I've done memtest, chckdsk, hard drive tests with seagate tools, scans with malwarebytes and avira, temperature readings with speedfan but nothing has been found. The only thing was with the chckdsk finding space mark as allocated that was free but I believe that problem was fixed in subsequent chckdsks.I have noticed these two error messages in my event log though: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.digital delivery service has terminated unexpectedly. it has done this (1) times.
