My system is very slow on copy paste.it takes 3-4 minutes to small data. In windows if i copy paste, it is ok. but in ms office, autoCAD e.t.c if copy any thing from one file to other file it takes 3-4 minutes. any thing from ram takes time. I think ram is not matching with processor. processing shows 100% but result nothing. Please help!!! my system is as under.
