I have recently bought some pc parts in order to built a complete system.After putting all items together (reset the bios) and press the power on switch.Although all the items seemed to work fine (fans cpu etc) nothing came up on the screen...I tested the cpu, memory, and graphics card on the system i am using now (having MB: ASUS P4P800) and everything work fine. The system has: P4@3GHz, ASUS P4P800 E-Deluxe, 256MB ABIT Radeon 9600XT, 1GB PC3200 Memory Module, HDD:160GB Maxtor ,Plextor DVD-RW Can anyone please tell me what is wrong?HELP
