Why this CPU wont work on my mobo?

[deiu99]

Hi
I bought a brand new Intel Pentium Dual Core E5700 3.0ghz to replace my old Intel Pentium Dual Core E2140 1.6ghz, but if I put the E5700, it wont boot, the PC just starts including fans, video card, hard-drive, DVD-RW, but I get yellow led at screen, so the screen is black(system wont boot), but if I put back the old 2140, it works. From what I founded out from Asus site my mobo is compatible with E5700 but only with the BIOS updated to the latest version which I have(0214), so I dont know what might be the problem. I confirm that the CPU is functional, I tested it on my cousin`s pc

power suply: ANS ATX450W P4

You didn't mention if you did a cmos reset after replacing the cpu... that might do the trick.

i did it, many times actually, it didnt work

You positive the new BIOS took? Sounds 100% like incompatible chip to me. I have had to redo a BIOS update because the flash didn't take and the original one remained. Only happened once to me in the 100 or so boards I've flashed but you never know. Also you might want to pull the battery and leave the CMOS jumper on CLEAR for a half hour or so just to make sure it has cleared completely.

The only things I can think of, very bizarre.

Remove the tuner, one stick of ram and make sure you have the CPU power cable attached properly. Sometimes bare minimums helps.


The E5700 is compatible with the 0212 BIOS, straight from Asus website. The manual is probably outdated.

The manual would only have the chips that were supported at the time of the printing and with the original BIOS which did not support the e5700.

so, the motherboard should work with my new cpu, the bios flashed succesfully and I can see in bios version 0214.
I tried everything:
-I removed the tv tuner
-I removed one ram, than the other one, lefting just one I have a 2gb and a 512 one
-I changed the supply
-I tryied with another video card
-I did cmos(by removing battery and with jumper)
-I even tried to flash bios with just the mouse and keyboard and monitor plugged in

but nothing........... :(
