my new rig gets a strange problem... CPU usage's always 100%... i thought it was caused by the virus, but the newest version virus software checked there were nothing. then i re-install the system winXP. through the installation, my computer worked so slow. setup win XP wasted me like 2.5 hours...it made me mad! i guess the CPU usage was also 100% during the intallation... i tried to change the hard drive and the memory, but the problem's still the same... does the video card cause the problem? or the cpu? the mobo??

i used the hard drive to install the system in my old rig and it worked nothing wrong... plz help me out...

ps: the first time i setup the window, it worked well. after i formated the hard drive and setuped the window again, the problem came... i press ctrl+alt+del, and check the cpu usage, the file"taskmgr.exe" always takes more than 25% cpu...

Wow, now that is really weird. Task manager is using up 39%...

Did you run memtest? It's always a start. Also, showing pagefile usage would be good. Did you install the soundcard drivers? Chipset drivers? ...can't think of anything else.
 
trying running some spyware program like ad-aware. there could be a bunch of reasons to whats going on, but sticking to basic things like checking for spyware is always worth a shot.
 
Your system process uses 50%, too. That's not normal. Was it idling when you take the image?
 
My roomates PC was doing something similar a while back, dont know if it is the samwe situaton here though. When you play music does it skip around if you try and open a program while its playing?
 
to PWMK2: i tried to change another memories, but problem's still the same... cpu usage is 100% during the installation of winxp i guess because it was too slow...and once it finish the setup and enter the window, i pressed ctrl+alt+del to check and i got those two pitcures above...so cpu used 100% without running any drivers or software...really weird...

to o0akoni0o: spyware? i tried ad-aware and got nothing wrong...i can really sure it's not virus because i change two hard drives and i formated both of them before install the window... if there is really virus problem, is there any virus can stay in the BIOS?? i setup different version of windows, during the installation, it ran really slow... wasted me like 4 hours to setup a window by x2 3800+ 2G memory??...i have no idea man...i check all the hardware except mobo, cpu and video card...

to vsrdan: "Was it idling when you take the image?" no... i pressed ctrl+alt+del and waited for a long time... then the manager appeared and i pressed the key"prtscn" from the keyboard to get the pic...

to Naldo: i really get no idea what happened to my computer... if it is the software problem, i think format the hard drive and re-install the system will solve the problem... but the problem still exists..."play music" i don't even want to run any software by my computer...'cause it is really slow...and everytime the computer enter the window, there will be a short music, right? by the cpu 100% problem, that short music skip around...
