Hi, I'm trying to figure out what's causing my friends evil IBM desktop computer to suddenly slow to the point it takes over 2 minutes to perform anything you ask it, whether opening the start menu or a programme, anything, it has an enormous lag, so bad you begin to think it has frozen completely, mouse cursor is the only thing that seems normal, the problem has cleared and her comp has started working normally a couple of times but only for a short periods (10 minutes or so). Start up seems normal, no errors, XP pro loads a little slowly but after that it's all downhill, it has had the HD replaced a couple of months back with a new WD 250GB, with XP PRO installed by a technician, RAM was also replaced with a new 512mb stick and the comp has CA Security Suite loaded and all up to date, all was working fine n dandy up until a couple of days ago when it just started going so slow it is almost went backwards! tried swapping out the PSU in case it was that but no change, no yellow!'s in hardware manager, no errors reported in system info, no overheating, no new software added recently ..any ideas what might be the cause? I'd be grateful for any help!!!
