have recently got a system assembled with the following configuration: AMD 64bit 2800+ processor/ASUS K8VX Mother board/40 GB SATA HDD/LG combo/64 MB XFX NVIDIA graphics card/256MB-400 HZ Hynix RAM. I am facing following problems: 1. The speed of the PC is increadbly slow when reading CD.. 2.LG combo sometimes reads the CD I insert...sometimes it doesn't. 3. Unable to make a data disc using Nero...While wriring It says"insert disc" while the disc is inside it...(I even tried using different discs). 4. cant open anything when A: drive is reading 5. My Computer often says (not responding.) 6. Task Manager takes ages to open. 7. Often my system hangs even if task manager says 2% CPU usage. Please suggest remedial measures.
