This is a Dell Inspiron 9400 with Intel T2250 @1.73 GHz and 0.99GB RAM that belongs to my wife. It's running Windows XP Media Center Edition Service Pack 3.
She's been complaining for the longest time that there's a delay between the keystroke and when the type appears onscreen. It's extremely aggravating when trying to type.
I don't know if there's a tweak that I can use to improve things to where there's no lag at all or if it's a hardware issue. It seems to be intermittent, also, not constant.
Tell me where to start and I'll gladly get back to you.
Many thanks in advance
