My father has a Desktop PC, and recently i have updated it. It had Win XP and 500 MB RAM and now i did put additional 3 GB RAM and Win 7 Pro 32BIT.
The problem is that it runs slow and whenever i tend to open an app, surfing the net, or watch a video online, it runs even more slower and eventually it blocks and needs restart.
The problem appeared from the beginning when i formatted the HDD and installed win, so there are no viruses involved.
Even in idle mode, the CPU usage fluctuates from 40% to 70%(or even more), on and on again, without any apps open. The CPU temp seems to be fine 50-53 Celsius Degrees.
While CPU usage shows high rates, the RAM memory remains aprox constant between 900 MB and 1,2 GB (all the time).
There are no suspect services running in background and those which are, don't consume the entire CPU at all (according to the TaskManager-Processes tab).
Intel Pentium 4 531 Socket 775 LGA - 3GHz
Motherboard: AsRock ConRoe865PE
RAM: 3,5 GB DDR400
Video NVIDIA GeForce 6200
It may be the CPU just too old for this OS?
