Hello, I have a new problem after I solved my old ones. I bought a Asus A7N8X and finally got the thing up and running with an Athlon 1400+ and 1 gig of patriot DDR400. I was messing around in the bios and clocked the processor to 166 on the Memory Bus and when I went to restart there was no post. So I manually flipped off the power supply switch to go about resetting the board. After I cleared the bios, the computer would not turn on. The power Led on the motherboard was on, but the board would not turn on still. I tried another power supply from another computer and it turned the thing on just fine with post and everything. I put the old power supply back in and flipped the switch on and still no power up, but the power LED on the board was still on. Could anyone tell me how to get the power supply to turn back on the computer? Before I bought the thing I put it on my tester and it passed. The power supply is a A1 brand with 300 watts with 10 amps on the 12v and 2 amps on the +5vsb.
