I posted this in others forums last week, but it still doesnt work. Here's the msg:

I replaced my Duron 800 with a Duron 1GHZ on my Asus A7V Rev. 1.02 today. All went well until I booted up for the time. At first, there was like 3 seconds of nothing (the fans and drives worked, but nothing on the screen), then beeps started to occur. They were long-short-long-short endlessly. I turned my pc off and turned it on again. This time, I waited to see how long it would last. Like after 10 seconds, my pc just shut down and wouldnt boot up again afterwards. I made sure everything was connected correctly and tried some different ram, but no luck. I thought the cpu was dead so I went back to my old one. Same problem. Wont boot up. When I press the power button, nothing happens. I tried different ram, a different vid card, took out the soundcard and modem, unplugged all the drives, and still wont boot up. It worked perfectly fine before. Anyone know what's wrong? I really need the pc for tomorrow..

Oh yeah, the board's green LED still lights up...

Since then, I've tried clearing the CMOS (touched the 2 metal dots with a screwdriver), trying three dif cpus (Duron 650, 800, 1000), used the jumpers for the multipier settings. Since the board's green LED board still lights up, i dont think the board is the problem. But I tried 3 durons and all dont work... I made sure the cpu fan is in the correct spot too... Anyone know what's wrong?


Oh, and here are my pc specs:

400W PSU
Asus A7V Rev. 1.02
512MB PC133 Ram
30GB HD
Aureal Vortex Soundcard
56k PCI Modem
Apollo Radeon 8500 LE

Everything worked great before I replaced the cpus..

I think you have accidently fried the motherboard and/or the CPU... Something was wrong the first time you tried to bootup... Those beeps you heard were error codes and was the motherboard trying to tell you what's wrong...

The fact that the motherboard's LED still comes up only means it's getting power, doesnt mean that it's OK...

Sorry dude...

Be sure to unplug the AC power before you apply the screwdriver to the solder pads when resetting the CMOS otherwise nothing is reset.

Check your pin setting for reset and power on switch,also reset your memory seems when people take out CPU,s due to the hard clips to hold it it on it is easy to unseat a memory stick,or crack a trace in the motherboard,so start out with nothing but your Hard Drive,Video card.good luck
