I have bought an 'ordinary' Asus P5E3 motherboard and an Intel Q9450 Quad core processor. But there is no POST when we turn on the compuetr - that is: the monitor stays blank although all the fans turn and motherboard LED lights up. We have put 2GB of DDR3 Ocz 1333MHz memory in all configurations and-nothing! We tried the memory in a Gigabyte board and it's fine. Then we tried the processor in the Gigabyte board and it would not POST. The graphics card is a Gigabyte PCIe x16 but there are no signs of rejection. Is it possible that I need DDR3 Graphics card? or is the processor faulty?

this mainboard is intened for use with XP or Vista only OS and Intel Socket 775 Core™2 Quad/Core™2 Extreme/Core™2 Duo/Pentium® D/Pentium® 4/Celeron Processors Compatible with Intel® 05B/05A/06 processors ONLY
if the computer powers on w/o video , it could be heat issue with the CPU, --turn off the computer, remove battery and rear case - remove the heatsink fan and apply new thermal paste on the CPU- then put heatsink fan back , battery -- and turn on computer --if the issue persists, its bad onboard video card
1 - Test the memory in another pc; if it's at fault change it completely. 2 - That 8 pin connector is there to provide extra power to the processor sources - either one or more of them are fried = replace motherboard or the processor itself is gone = test it in another pc and replace it if necessary.
i have a ecs g31t-m with a pentium e5200 dual core. i bought the board from ebay and the bios needed to be flashed before it would reconize the processor. after flashing the bios i still had the same problem. i found that in the user manual there is a list of "qualified" ram. before looking at this list i tried some ram that was not on the list and it wouldn't boot. after changing the ram to one that was on the list it finally booted up. however, after getting it to boot and reloading win xp, i cant get any drivers to load for the onboard equipment. so now i'm stuck. i hope this helps and if someone can give me direction on the drivers i'd be in good shape.
