I pencilled the wrong bridges on my Duron 600, now (even after I erase the lead) nothing happens when I boot. System gets power etc. But the monitor says "no signal". I get the same thing when I remove the CPU completely.
QUESTION; Which part did I kill? Motherboard (Abit KT7) or CPU? What I need to know is does a sytem "boot" and display "no cpu" or something when there is no CPU or does posting such a message on screen require the CPU?
The system will not come up without a cpu. My guess is that it is the cpu, but of course you should try and borrow one from somewhere else to test that theorey.
I have the same "no signal" problem with my comp. I'm afraid maybe I broke the processor when installing the heatsink on my 1 Ghz Tbird? Is this easy to do? By the way, what does pencilled wrong bridges mean
You may have some residual pencil graphite stuck in the small cracks keeping your bridges connected. Try cleaning the CPU out of the case with rubbing alcohol. (Soapy water might work but dry the processor thoroughly after trying this).
Before you do either of these try booting in failsafe mode as one other user described using the <b>insert key</b>. (You need to disconnect the powersupply from AC first with a switch or just disconnecting the plug). You can also <b>reset the CMOS</b> using a jumper on the motherboard. I forget the name of the jumper but just more it (with the power off) to the alternate setting for 10 seconds then put it back. Boot the computer.
I don't know about the Abit KT7...
But my Asus A7V beeps when the CPU fails, or when there is no CPU. If I remember correctly, the beep was a continuous tone.
