Hi, I'm running Vista Home Premium 64 bit. I use this PC almost exclusivly to run Flight Simulator X and when running FSX I'm getting a stutter about every 2 seconds. After some research I downloaded Process Explorer to find out what was causing the problem. I discovered that it is a SVCHost and specifically a RPCRT4.dll that is the culprit.
This dll is in the same svchost as dcomlaunch and plugnplay. Every time it starts it comes up to 1.52 CPU usage. I am running ESET NOD 32 AV and I have run it many times with no results looking for a infection. I know that dcom and PnP cannot be disabled but I'm hoping that some one here can help me with this problem. I have downloaded GMER but I'm not sure what to do with it.
