Jacqui Too Posted January 31, 2010 Share Posted January 31, 2010 I've been having trouble with my PC for a little time now, its only about 2 years old, so it's not clapped out yet!After it has been on maybe 1/2 hour it starts to run slow (or fast which ever way you see it!) The CPU's rise to 80-100% and stay there making it almost impossible to do anything with it, the internal fan comes on and whizzes like a mad thing for minutes on end, I have looked at the task manager and can see that the main culprit in the rise of CPU's is a process called 'Percentage of time the processor is idle' which runs at between 40-83% most of the time, the only way out of this is to do a restart.Can anyone help or does anyone recognise this problem and what can I do about it?

Alex H Posted January 31, 2010 Share Posted January 31, 2010 Quote from liutilities website "the System Idle Process is not aprocess, more a counter which is displayed in WinTasks used formeasuring how much idle time the CPU is having at any particular time.This counter will display how much CPU Resources, as a percentage are'idle' and available for use. Cannot be killed"So if system idle process is showing 100% it means that nothing isusing any cpu power and it is all available for use. This is completelynormal.However, the rest of it needs a look at - have you done a full virus scan? Link to comment Share on other sites More sharing options...

When this is running so high the PC will crash if I ask it to do to much and v.slow if it can cope at all. Link to comment Share on other sites More sharing options...

Jacqui Too Posted January 31, 2010 Author Share Posted January 31, 2010 Well if I click on CPU it changes so quick I cant read the processes[:-))] but if I look at processes the CPU still change a lot but this is how it waswhen it is whizzing:IE around 14Side bar around18 Google chrome up to 35Task manager up to 25mcci+Mccitray app 10Avg residence shield service 10Host process for Windows services 10[8-)]Edit : its taking so long to reply that I think I will do a restart Link to comment Share on other sites More sharing options...
Nell Posted January 31, 2010 Share Posted January 31, 2010 Is it a laptop or a desktop?? May sound a bit daft, but try running the vacum over the fan vents, or try blowing the dust out of the fan casing. If the fans get clogged with dust, they run more, heat the computer parts more and this can really slow things down.... Link to comment Share on other sites More sharing options...
Jacqui Too Posted January 31, 2010 Author Share Posted January 31, 2010 Not daft at all Nell, but I already did that a few weeks ago and it didn't help, I'm really flummoxed over this and now the little bugger has been as good as gold all afternoon since I did a restart![:-))]Edit: Desk-Top Link to comment Share on other sites More sharing options...
