Hi all, I was wondering if you could help me. Im having alot of problems with my pc recently, besicaly what happens is i can use my pc for a certain amount of time (roughly a few hours sometimes less) until it comes under some serious slow down and ultimately cuts off.

Now i keep an eye on the cpu usage and its up and down like god knows what. It can be 4% one second and then 88% another without me even doing anything to it such as opening applications. I have noticed that msn likes to take up alot of cpu usage at times and is around 80k when only having like 2 windows open :S

It might not have anything to do with the cpu usage but its becoming a consistant problem and is realy annoying!!! Another thing, iv checked the fans in the system and all of them stil work (3 of them, one on the graphics card), so it cant be tht.

Can anyone help me with this problem? Any help at all would be appreciated thanks alot Mozza

Ps bare in mind im a pc newbie

A few details regarding your system specs would be useful. Have you made any software changes that could be effecting the system, sometimes antivirus scans and spyware scans can be very processor greedy. My MCAFEE can use over 80% of CPU. monitor your task manager and look in the list to see what is using the most. Right click on the blank area within the task bar and select task manager click on the process tab this will list all currently running processors. If you only have a small amount of RAM in your system it could run slow when scanning with security software, you could try adding more RAM, its a cheap and easy way of increasing a systems speed. RAM is now very cheap, I have just fitted a 1Gb stick for only £60.

The main thing which uses up cpu usage is msn (50-80k) and internet tabs (50+k)

Im starting to think its more to do with the weather as its very hot at the moment.

If the problem stil persists when the temporature has dropped i will try RAM and see if that makes the difference.......i hope so.

Thanks for the help
