In fact they call any hour of day or night because THEY NEED THEIR COMPUTER BACK!!!
I received another such call this morning with a common problem of this last year - the svchost.exe bug that takes over your CPU. Symptoms include the PC seeming to be "almost" locked up, not able to open a program or it takes a very long time and your Hard Drive light flickering indicating its working without any obvious programs running.

If you have this problem you will see svchost.exe running at 90%+ CPU usage when viewed under processes in Windows Task Manager, accessed via the Three Fingered Salute (control-alt-delete). If it happens to you, here is how to fix it step by step:
