Hello, 775VM800 Pro-DDR2 As Rock M/B run all fans but doesn't boot, no deep sound and no video
Regards,
You didn't post enough info. Please list your CPU, RAM, & power supply. Are you 100% sure the CPU is supported? Is the heatsink/fan installed correctly & thermal paste applied properly? If they're done wrong, the system will not boot. It's an old board & not particularly a good one.
