Computer doesn't power up?
I just installed a new motherboard for my friend, but it doesn't boot up. :S The LED on the motherboard is only light up at half, it's like if there is not enough power, but the power supply is still a 300W for an ASUS K8V-X, it just doesn't power on. Even tough that I don't have any hard drive or CD-ROMs plug in. The specs:
No brand 300W PSU
Sempron 3000+ 64Bit
ATI Radeon 9200SE 128MB
Can someone help me on this one? I tough that it would be the additional 12V rail that I need to plug in into the motherboard but no, it's not that, I plugged it in, tried with the one directly from the PSU and with an adapter.
