CPU usage 50% after exiting a game

[Heksmeester]

Hello all

Whenever I exit a game after playing it for a while, my CPU usage will sit at 50-60% on idle and the PC becomes very unresponsive. The only way to fix this is by restarting. At first I thought it was a cooling problem, so I blew all the dust and other crap out of the heatsink and applied some new thermal paste. Worked fine for a few days but now the problem reappeared. What could be wrong here? :erm:

CTRL+ALT+DEL and see whats using your CPU?

explorer.exe. It's impossible to tell. I've killed it and restarted but that didn't help either. :/

Explorer will be your general desktop loading up. Hows your ram? Or maybe you got windows search and indexing services runnig?

Ram's doing fine and levels are normal. Why would the indexing service only start after exiting a game? That's the only time the CPU does this.

Run behind maybe. It's designed to utilise your CPU when its not being utilised by a app in the forefront. A game will be a cpu hog. I'm just shooting in the dark here, check in your process list for the index and other services but normally if I exit out of anything my CPU may burst for a bit regarding getting the desktop environment back but seconds later it idles at sub 1%.

Use Process Explorer from SysInternals to view the CPU usage, HDD utilization and memory usage. I would suggest that you enable the CPU & I/O history columns, so that you have a graphs for each process.

If you have like 2GB of RAM and Windows 7, then it is most likely a RAM issue, because most games would require you to have like 3GB of RAM nowadays.

lol wut?. Examples of issues it can be though in my experience either a driver issue, svchost issue if you dont update your windoze, a virus or modded system files. Have a look on the interweb for the fixes for these problems but frankly I've found that its easier to reinstall most of the time for this sort of problem as its a pain to pinpoint what specific, process, program or driver's causing it.

Yay for fail interwebs.

Run "sfc /scannow" in command prompt just to make sure all system files are OK.
Run Msconfig and remove anything from the startup items that's not needed and reboot (in fact, I usually suggest just removing everything there).
Get a copy of Malwarebytes, update it and scan your PC, just in case.
Run Microsoft essentials virus scanner, just in case.
Make sure you have the latest display drivers. Even if you do, remove and reinstall them.
Get a copy of CCleaner and run a registry scan, remove all issues (maybe do this just after removing display drivers)
