hey, i recently formatted my hd, when i re-installed windows (xp) i noticed that the longer the pc was runing my mouse started to lag every 2 secs for a period of 4 secs at a time, upon looking at my processes in the task manager, i noticed my cpu usage was going to 100% for 4 secs then back to between 20% and 40% for 2 secs, it does this repetedly and all i have running is msn messenger, but it does it when nothing is running too ;/ i realy cant do a thing with my PC, as in play games, which i need to do as i run a clan for RTCW. ive reinstalled and re-formnatted 3 times, and still the same. i installed diff video and sound drivers every time and always made sure that i installed the chipset driver first b4 anything else, i have a friend who is very good at this stuff, and even he is stumped, anyone got any ideas? pleeeeease

PS. please view the attached jpeg of my cpu usage to understand what im jibbering on about

Go to the processes tab (of the window you posted) and list the top few processes that are eating up all the CPU.

Also, do you have one of the new Pentium 4s with Hyper-Threading technology? (Actually, nevermind ... if you did, it would be displayed as 2 CPUs)

That's odd.

Processes tab, yes. Do you have SP1 installed?

By the looks of it your CPU has a very fast pulse rate.

(The graph looked like a cardiogram... )

Whatever this process is, it must be doing something big every couple of seconds. Are you networked or anything, perhaps acting as a server for user roaming?

[ Post deleted that was above here ]

Erm, I hasten to point out that the RPC service doesn't appear to be failing here. Otherwise the computer would reboot, not just slow down.

Hi, thanx for the quick response ppl, the thing thats using the cpu is DLLHOST.EXE means nothing to me, but maybe you guys will know.

NO i dont have sp1 installed, i was warned about it, so i never got it, basicly, i have audio and video drivers, msn and rtcw (return to castle wolfenstein) installed.
