  1. I have a ASUS A7S333 mobo and the processor is 1ghz AMD and I am going to replace it with a 2ghz processor amd and I did check the specs and the processor will work . I did replace that now I just get a blank screen then I put in my old 1ghz processor back in and still get nothing but a black screen.The steps I took,#1 Took everything out and seated it back in #2 took the cmos and put it back #3 make sure that my monitor is plug in right .Now when I boot it up I have to use the power botton in the back before it was the front one and my cd-rw light keeps flashing and making a knocking noise every second no beeps though.So it boots up the light on the mobo (led) lights up ,cpu fan working,hd working .I guess everything else is working cause I hear no beeps.But still no picture. Before I added the new processor everything work with no problem. Any help would be great.

    Could you give us the rest of your system specs please? Specifically the type and wattage of your power supply......sounds like it could be on the weak side. Also (I'm not familiar with your motherboard) does it take the extra 4 pin 12V plug to the motherboard and it that plugged in as well?

    "took the cmos and put it back" :confused:

    What you should do is power-off the machine, unplug the PSU, set the Clear_CMOS jumper to 1, wait a few seconds, set it back to 0, then plug the PSU back in & power it on.

    You can also try keeping the INSERT key pressed down while powering up, some boards use that to reset the BIOS to default values.

    You can also try powering on the mainboard without any CPU & see if it does beep.

    Which CPU is it ?

    If it's a 2400+ ( 2GHZ ), there are two versions : Thoroughbred & Thorton ( crippled Barton ). The Thorton is only supported with boards revision 1.03 so make sure you have a Thoroughbred or that your board is recent enough.

    So if I take out the cpu and start it up and it doesn't beep is it the motherboard ?

    Well if the mainboard doesn't beep without a CPU installed, it is either the mainboard or the PSU not powering the mainboard.

    Is the VGA card nicelly fitted ? Try reseating it, as well the RAm ( that can't hurt ).

    Check to see if the mainboard isn't shorted somewhere. If not, it would seem like the board is the culprit. Is it still under warranty ?

    Well I took out the memory and the cpu at the same time and it didn't beep.It should beep if there is nothing in the slots right?
