We, my son-in-law, grandson, and myself are trying to build a gaming machine. So far we have assembled the following: CPU is intel Pentium 4 3.0G (800Mhz) Mobo is Aopen AX4C Max, Intel 875P Chipset Ultra ATA133 ATX Form FActor w/1AGP98X), 5xPCI + a lot of other stuff RAM is Crucial / Micron 512MB PC3200 400Mhz CL3 DDR DIMM (1 stick) Vid card is ATI | Radeon 9800 Pro 128M 8X RTL Harddrive is WD Caviar 205 BA 20.5gegs connected to mobo with 80 wire flat cable, just formatted for fresh install Monitor is a 17 inch KDS Visual Sensations 19" and has been working flawlessly for a while. 3.5" A drive Nothing else When it is switched on the fans start working, an LED on the mobo flashes once and another comes on steady, nothing on the monitor except it's on self test which comes on if nothing else comes on, and a squeky scratchy voice on the pc speaker which sounds like it's saying "CPU idi" or "CPU edi" or maybe "CPUvdi" or no telling what. The mobo and cpu were ordered as a compatable unit from mwave.com but not assembled. The cpu had an intel inside label on the flat side that mounts to the fan heat sink. That label was removed. The ram was ordered seperate. The monitor and HDD were on a previously owned computer and working fine. Can anyone suggest a solution or advice on the compatability of these parts. thx Tommy Mathis
