Hi i'm new here, and im in need of help. For a few weeks now explorer.exe has been misbehaving. It does not do it after bootup but it always starts using 10-15% of my i7-2600 devided over several threads/cores after i have played a game of league of legends. I have tried the folowing: - turning of all 3rd party shell extensions, using shellexview. - reinstaling league of legends. - used procesexplorer to try and pinpoint the misbehaving entry, and it just shows explorer.exe. - reinstaling graphic drivers (i got new ones for a new graphics card just before this started). - runing any other game or graphics application does not produce this problem. - killing explorer.exe, when its down my cpu drops to normal usage, when i restart it using taskmanager it starts to consume alot of cpu again. -tried killing explorer.exe before/during gaming and restarting after gaming, did not work. A few details about my system: - Asus desktop CM6730 (dont know wich motherboard it has). - Windows home premium service pack 1. - Intel core i7-2600. - EVGA gtx 660 ti (now using the nvidia drives, before using the EVGA drivers). - 8gb of ddr3 1333mhz memorie. - 600 PSU (should be/is enough). - Trend micro titanium maximum security antivirus. A few details about the problem: - If i leave my computer be and dont do anything the cpu will after some time drop to normal levels and every so often spike up to 10-15% again and then go back down and continue to increase and discrease. - If i move my mouse my cpu will instantly climb up to 10-15% and stay there, and will only drop a while after i stoped moving my mouse. - If i kill explorer.exe moving my mouse does not provide the cpu increase. I would like to fix this without the need of restoring to a previous point. So i hope that there is someone that is willing to help me with this, i can send .dpm files and such if needed. Sincerely Mark.
