Motherboard not posting

[brollybrom]

Just got a system that wont show any signal.

Q6600
PT573
4GB DDR2
R9 255 2GB GD5

2 of my monitors say no signale, the GPU Fans are not spinning (Only for like 0.2 sec) only when i insert the 24 pin not correctly, than they spin 100% The GPU fans do spin fine when tested on a other motherboard. Also the Onboard VGA isnt working but im also not shure if the Mobo has iGPU. I cant get into the bios at all. The PSU working fine probally. I already tried removing the CMOS Battery, no luck.

Is this your MB? https://microdream.co.uk/asus-pts73-packard-bell-stingray-socket-lga775-core-2-quad-motherboard.html

So the problem may be from the Q6600 or the memory, or evne the MB is not good. 1) The MB can only support cpu with or up to 95W TDP, but the Q6600 has 105W TDP https://ark.intel.com/products/29765/Intel-Core2-Quad-Processor-Q6600-8M-Cache-2_40-GHz-1066-MHz-FSB 2) Aslo the MB may or may not have the right BIOS. 3) the MB ( pt573) can only support up to 4GB RAM, that means the RAM size will be 2GB each, if youe RAM is 4GB single stick, the MB will not boot.

You may try remove the RAM to boot the PC to see it can boot or not, by the way, that MB has onboard iGPU, which is the NVIDIA GeForce 7050 GPU.
