1: Are you saying that when you run a program the CPU use jumps to 100% and then stays at that level for as long as the program is running, or does it eventually subside?
2: Registry cleaners are largely worthless programs. They save, at most, maybe a few kilobytes of memory, and they have the very real risk of wiping out some very important bit of data. They offer no real benefits in regards to system performance or stability.
I have a Windows XP Professional computer. My question is about the 100% CPU usage it shows in Task Manager whenever I run any program. No matter what the program is.
It is a 3.40 Ghz Intel Pentium 4 with Hyper threading and I have 3GB of RAM. I do have the processor turned on and that has seemed to help a little bit. What really disturbs me and maybe it's just because I don't understand this computer, but as an example if I'm running Nero, the CPU will be at 100% but the memory it will be using is less than a GB around 700 to 750 MB. I do not understand why this computer is not using its memory more efficiently. Anyone have suggestions? It sits at idle and only uses from 0 to 8% CPU but as soon as I use a program the CPU spikes to 100%. There seems to be no spy ware or viruses on it and I run registry cleaner regularly. I'm stumped?
