I Have a 2yr old Dell Dimension 4550 with win xp, pentium 2.4g processor, 256meg ram, 60gig hd, cd burner,& dvd rom. It got to a point it would take 20 min. to boot up, then run at a snails pace. I ran spybot, adaware, and McAfee virus scan and no change. I ran hijack this and found no problems there. I installed new hd and ide cable and fresh install of xp and no change. from there I changed out the ram and no change. I disconected all the cd, dvd, floppy, removed the modem, sound card, reinstalled xp with no drivers for the cards, still no change. At this point I replaced the power supply, removed from another running computer. Each time I made a change I checked in task manager and found the CPU usage to be 20 to 30% with no programs running. the tasks that are consuming the CPU are the taskmgr.exe and explorer.exe. at this point I even upgraded the bios and still no change. Does anyone have any other ideas.
