CPU problem

Hi folks, new to this site, no sure if i'm posting in the right place. Anyway, here goes. I have XP home edition on my laptop, about 2 weeks ago my laptop started having probs, the cpu usage kept shooting up to 100%. I figured it was some kind of virus and wiped the whole laptop (yes, i actually wiped it, not just created a new partition), and all seemed fine.

Last night, exactly the same thing started happening, when i turn the laptop on it takes ages to boot, the windows tune that plays on startup sounds all dodgy (no, it's not the speakers) and the cpu usage is a pain. When i booted up today the first thing i did was open task manager and check the cpu usage, it was at 100% without me even doing anything. It eventually went down to less than 10%, but if i open up explorer it shoots back up to 100% again. In task manager i prioritised the processes by CPU, and for some reason Sytem Idle Process was flickering between 98-99.

Can anyone help?

 

nope, after i wiped the laptop, the first thing i did was to get all the updates for windows

 

Sorry it's taken a while to respond, my internet is going extremely slow, another by product of my problem. Okay, i noted down which processes were doing what when i turned my laptop on, here they are...


svchost.exe 23,160 K

CCAPP.exe 16,172 K

yop.exe 18,968 K

explorer.exe 16,180 K

LUCOMS~1.exe 11,448 K

everything else is under 10,000 K

These were the worst ones, there were 56 processes in total. Bear in mind that all i had done here is turn my laptop on and opened task manager, so i don't get why things like explorer exe were running.

 

that's the thing, i'm not running two programs, i had to get rid of everything else to install norton protection centre, with came with bt total broadband, and since i did that i wiped my computer then reinstalled norton, so there shouldnt even be any traces of another anti virus prog.

 

is YOP.exe the same thing as YPO.exe? I don't have a process named YPO.exe. Do you think it could be Norton? I have heard about folk having problems with that.

 

Lol, no probs, i ended up wiping the laptop again, it was getting worse. When i reinstalled everything i kept norton off it and put on avast, comodo, and spybot, just have to wait and see if the problem stays away this time. Having probs getting it connected to the internet now but that's a whole diff kettle of fish lol. Maybe some day some one will invent a computer that actually works the way it is meant to!
