100 % CPU Utilization
I have 1 gig of memory installed, but when programs load or are being installed, the CPU utilization goes to 100 % and stays there for a long time. Would a memory upgrade to 2 gigs help? Or something else? Bob from Shalimar, Fl

- That CPU should perform well enough and the CPU utilization is not normal.
Open task manager (control-alt-delete). Commit Charge is show at the bottom. Look for the processes using the CPU resources. On the Performance tab look for the Total Physical Memory.
Peter - So you are saying the CPU utilization goes to 100% for a brief time (how long) when loading those programs?
I just loaded Word and the CPU (one core) went to 100% for about 1 second.
Actually, here is a thought! It might be that your disk controller is operating in PIO mode which takes CPU cycles. Normally, they operate in DMA mode which is done independently of the CPU. This only applies if you have IDE drives or are operating in an IDE compatible mode (I believe ... my SATA controllers do not have this mode).
Check in Device Manager (right click on My Computer and select Manage and then Device Manager) to see what modes you are operating in. Look under the properties of the controllers. Somewhere it tells you what transfer mode is in effect.
You never said what machine you have, so it is hard to know what hardware you actually have.
Also make sure the Policies for your HD in the Device Manager is set for "Optimize for Performance".

Check in task manager to see what is running and using the CPU. Also check to see how much of your memory is being used (Commit Charge). You can use more memory if Commit Charge is much greater than 1G.
You can use something like CPU-Z to check the actual clock rate the processor is running at to make sure it is what you expect.
