Just did a clean install of Windows XP Pro SP3 on an older HP laptop...it's got at least a 2GHz P4 and less than 512MB of RAM (will have to post back with the exact amount). Nevertheless, I was able to reduce memory usage by disabling non-critical services, and it runs great until the svchost process suddenly overloads the CPU and I have to terminate it in task manager. I understand svchost is a service host process, which leads me to wonder if tweaking the services is what created the problem in the first place. It's weird though, because I've done it on a dozen machines with great results and never once had this problem. Is there a way to see which particular service is causing this CPU overload, or a fix that I'm unaware of?
