Thread: Windows 7 svchost.exe high CPU usage

After running anything that requires any CPU power ( Youtube, flashgames, Java, ANY pc game like Counter Strike, Left 4 dead etc) svchost.exe uses a lot of my CPU ( 50% +) and stays like it even after closing whatever I was running, I always have to reboot. This has only happened in the last few weeks.
OS: Windows 7 Ultimate 32-bit
Browser: Firefox

Things I've tried:
Downloading processor explorer and checked what is hogging the CPU under svchost, it turned out to be critical services I cannot end. (Picture below)

Scanned with Malware Bytes & Microsoft SE ( Both updated, showed clean, multiple times)

Defragged my HDD, cleaned my registry, Windows is up to date expect for 1 Windows Update that will not install (When it configures after I reboot it fails and reverts changes, every time)

Scanned with Hijackthis (Log below)

No luck.
