ASUS A7N8X won't post

[RMSistight]

The computer would start, but no video would come on, and then it would shut off by itself after like 10 seconds.

Tested RAM, CPU, and cleared CMOS. No luck.

Mobo fried? What do you think?

My A7N8X did that last week but pulling the CMOS battery, moving jumper back and forth, reseating battery did the trick for me. If it hadn't, my next guess was going to be psu but that's just because I'm running a simple psu that came with the case. Do you have another psu you can try before you rip out the board?

Check your heatsink installation against my photo guide here. Third and fourth photos should be pretty self-explanatory

If that's not the issue, then post full specs in detail, including brand & model of the power supply and the RAM.
