I am building a PC for the in house design team and have the following components.
P4E 3.0 1MB S478 800FSB
AOPEN S478 SiS655FX ATX A L Motherboard
GF FX5600 256MB DDR AGP RP Graphics card
2x512MB 184DIMM PC3200 NP CL3 RAM
The computer has been built, everything fires up i.e. Processor fan kicks in, HD ticks over and there are no beeps being emitted.
The problem is that the monitor does not come on.
Several different monitors have been tried, the RAM has been changed, the processor has been changed, the CMOS has been cleared with Jumpers and by removing the battery. The system has been set up outside of the Casing to check for shorting. A PCI graphics card has been put in instead of the AGP and still we have the same result…nothing. This is the second make of motherboard we have tried, the first had the same result. The AGP has been tested by the manufaturer and they say it works fine and have managed to run Apps through it.
So what is wrong? Am I just getting a run of bad motherboards or is the AGP burning them out?
