Whenever my computer starts, i always wait for the red light in the CPU, which indicates the CPU is busy, to go off but it's taking too long. When i look at the task manager under the processes tab, The svchost.exe uses 99 percent of the CPU and it as the highest memory usage of all processes. What is the svchost for? And also, there are about 5 "svchost"s under thre processes tab in the task manager. I am using a pentium 4 PC with 512 mb of ram.
