My mates pc shows 100% cpu processes and the graph shows 100% also, hes running windows xp, sp3, ran all the scans in safe mode, i.e. malware bytes S.A.D, super anti spyware, AVG and nothing is found. Any ideas.

nozzer

Is he running anti-virus ?

Quite a few of them are very good at running the processor at 100%

Take a look in the task manager and find out which task is hogging the processor.

bash213001

not got 2 antivirus proggy's running mate has he,also could be a driver conflict,remove graphics driver and reinstall it,had that once

thomasjcat

He's running AVG only, had his pc wiped recently, could it be the driver for the graphics card.

RAB - P

has he got virgin PCguard running on his machine somtimes that kick in an takes all the processor power

Click on CPU column header to sort (might have to click twice to sort correctly high to low)
what ones are using the highest % (apart from system idle)

thomasjcat

In task manager, system idle 50%, task manager 50%, total cpu usage at the bottom is 100%, the graph is 100%.

Strange, System Idle usually doesn't contribute towards the graph or processor load. It System idle is 50% then I would expect the processor to be only 50% busy.

Task manager using 50% is an indication of something seriously wrong in Kernel mode. Very likely a driver is sitting in a loop or something similar. This could be down to all kinds of problems from damaged drivers to mis-configured or spurious interrupts.

Last time I saw this was when WMP11 was trying to add an incomplete Divx movie to the list of shares, the thing hogs your CPU endlessly until you remove the dodgy file.
