Prior to making this change everything worked fine. I checked the specs of the motherboard for front-side bus compatibility...that is fine. Without disrupting ANYTHING else on the motherboard, I removed the fan/heatsink & old CPU (2GHz Celeron, and replaced it with a 3.06GHz Celeron. After seating CPU in the socket properly, and putting the fan/heatsink back in place...I booted up, but got no post beep & no output to the monitor. Any idea what could the problem? >> Stay informed about: No post beep or monitor output after changing CPU.

Your new processor is incompatible with your motherboard. Or there are improper settings. See if there is a BIOS upgrade that allows support of the new processor. >> Stay informed about: No post beep or monitor output after changing CPU.

If u read my initial message, I checked ALL specs for the motherboard & CPU....it IS compatible. I'm no new jack to computer building, this is just a unique situation I have never run across b4. >> Stay informed about: No post beep or monitor output after changing CPU.

Without that information, it's a bit hard to track down the issue. PPS: You may want to try reaseating the memory and power connectors. One of them may have come loose while fiddling with that Pain in the Ass P4 heatsink. >> Stay informed about: No post beep or monitor output after changing CPU.

Did you try it a second or third time? Often a system will need a 2nd or 3rd attempt, the first time it can't boot because it's trying to use the old settings then on subsequent attempts it has adjusted them. The alternative is to clear the CMOS first, by jumper or removing battery for several minutes while AC is disconnected from the PSU. You checked FSB compatibility but what about CPU family compatibility? Why are we not given details of the specific motherboard, since it's a pretty important factor? Did you check (is there a) manufacturer's compatibility chart that specifically shows this CPU or at least one in the same family (not just Celeron or same FSB) working? You might try putting the old CPU back in and flashing the board to most recent bios if you hadn't already. >> Stay informed about: No post beep or monitor output after changing CPU.

So you aren't, for example, placing a 90nm processor, in a motherboard that only supports 0.13u processors ? That is known to result in a black screen and no beep, due to the BOOTSELECT pin. An old S478 motherboard grounds BOOTSELECT, and a new processor knows not to run in an older motherboard as a result. Paul >> Stay informed about: No post beep or monitor output after changing CPU.
