Motherboard/Video Help

The 3 things I gave him:

Asus A7N8X Deluxe
AMD Athlon XP "Barton" 2500
ATI Radeon 9800 Pro


I am upgrading my PC and and gave my friend my old CPU/Mobo and Video card while he ordered the monitor and the rest of the stuff. I used my PC earlier today and it worked perfectly fine. Once he puts the 3 items I gave him into his stuff, the PC will turn on but we get no video feed from the monitor at all.

We have tried 3 video cards ( with 1 PCI card) and 2 monitors and still can't get anything from the monitor. If we unplug the monitor we get the "no signal" from the monitor, and when its plugged back in it goes away just into standby, and when we turn on the PC it stays in standby. We've reseated the video card several times and changed some RAM slots as well. The PSU is a 430 PSU, but its pretty much a no-name, but the specs aren't that big.

Only thing I can think of is the motherboard is bad.

Any ideas?

1) Remove the motherboard from the case and lay it on cardboard outside of the case. This ensures that there is no possible short-circuit situation involving the case to complicate your troubleshooting efforts.

2) Unplug the power supply from the wall, remove the CMOS battery (round battery on motherboard surface), clear the CMOS for 30 seconds using the CLRTC jumper, then put the battery back in and plug the power supply into the wall. Page 21 of the A7N8X Deluxe manual shows the location and usage of this jumper, if you need that.

3) Check that the stepped end of the heatsink base is above the raised, solid-plastic end of the CPU socket, see the third and fourth photos on this page for illustration.

4) If that does not help, then test it with your power supply, the one that it worked with before.

5) When using the 9800 Pro, check that he has this cable plugged in.


Good luck, hope that helps

Thanks for the reply.

The problem ended up being the ram. One of the two sticks of 512 is bad.
