Have just used Pcpitstop to run a tune up on my PC. It is OK apart from poor performence from my hard drive. IE:- Drive C has cached speed of 136.13 megabites /sec when benchmark is 222 mb/sec. Has anyone know how I can adjust this speed. I run win98snd, 40gb hd,1.4gb processor,512mb memory on a ASUS A7A266 board. I disabled virus checker (Panda Titanium) wilst running the tuneup program.
