I recently bought a new HDD 300 GB Maxtor. Installed it and installed winxp professional.. I use some graphics programs, e.g. Corel Draw, Photoshop, etc. Everything is fine, but every now and then, it will stop responding. I can click away on all the icons, but it won't do anything.. and then maybe after a minute or 2 it will start responding. There's no particular pattern to it, nor there is any particular program responsible. I have 1GB RAM, there's another physical HDD present (my old HDD), one CD-RW and one DVD-RW. It's Pentium 3.8 GHz clone pc. any help would be greatly appreciated. thanks.
