I had posted a thread in another section about how my computer starts bogging down real bad after I play a game that requires alot of resources or watching a movie on my pc. While playing games or watching movies there is no problems but as soon as I shut down everything becomes unbearably sluggish. I can do ANYTHING I want all day long and never have a problem as long as I dont do the aforementioned tasks. Task manager says explorer is eating 97% cpu after I do either of those and I used procxp to search a little more and found it was a ntdll.dll file. Under threads start address it reads exactly "ntdll.dll!RtlpUnWaitCriticalSection+02a" I have no idea what the hell that means but if I kill the thread explorer shuts down and I have to restart my computer. If anyone knows anything about this problem or can point me in the direction of where I can find some answers I'd appreciate it greatly. Thanks!!!!
