I've had this desktop computer for maybe 6 years and the performance has been merely okay but something has been amiss the whole time, I am quite certain. I have begun finally to get an inkling of the source of the problem. Sometimes it takes 45 or more seconds for a simple text file to open. But it always finally does open! Sometimes my machine makes whirring noises, like the hard drive is overworked or something else is laboring. Now I finally see what I believe to be the root of these danged problems. Looking at Task Manager there are of course many many entries for "svchost". But how can I differentiate what each one's function is? ONE of those entries is hogging CPU at an alarming rate, using about 50% capacity nearly ALL the time! ...and it is hogging immeasurable memory too: often more than a gigabyte!! PLEASE: can someone help me to determine the matter. I honestly don't think this is caused by any malware, or I would see other troubles. I can instruct Task Manager to End the offending Process, but that leads to an inability to retrieve my email, and the process doesn't actually get off the list AND the huge memory allotment is NOT freed up either. If only I know what precise service this offender represents, and I could disable it in MSConfig or something. I will supply more info on subsequent posts. Kindly offer me insight. The PC is an HP SR5510F AMD Athlon 64x2 dual core 5000+ 2.60 GHz with 2.87 GB and 32-bit Operating system. More to come when if needed. THANK YOU!
