I am running a fairly average PC with windows xp, 2.66Ghz celeron cpu 512RAM and Radion 9200LE graphics card. I recently took parts out of my system to troubleshoot a problem with another PC. These parts include RAM, CPU, PSU and graphics. All the parts have been replaced and double checked (for loose connections etc.) but there seems to be a problem. My PC is running very slow videos are jumpy and i can not open more than one program at any one time without it practically stopping. I run two ant-spyware programs and ad-aware also regfix and ccleaner and AVG. The hard disc does not need defragged and when i run SiW it tells me all my hardware is ok. Is there anything else i can try? Thanks for reading.
No, not under Memory usage - look under CPU see what the highest % usage is. Apart from System Idle Process near the bottom which is usually about 87% and which is normal, see if anything else has a reading in the 90-99% range - if there is such a reading then that is what is slowing the pc.
