Computer wont boot after installing new cpu.

[Zackiz]

So I installed a new cpu and the computer wont boot. It starts, the cpu fan sounds like it goes up to max for a few seconds, then goes back down and the computer is on, but it doesnt do anything after that. It wont even get as far so that I can get into BIOS. I can then swap back to my old cpu and everything works as it should. I have updated my BIOS when I had the old cpu installed. I have checked and doubblechecked that is was correctly installed.

 

What should I do next? I'm out of ideas at this point.

 

New cpu: Intel Core i5 4690k

Old cpu: Intel Pentium G3220

Motherboard: Asus B85M-G

Put the pentium back in and update to the latest BIOS found on the ASUS website. 

 

To further explain, the 4690k is actually a Haswell refresh chip, so some B85 boards need a BIOS update to support them.

CPU may be dead if everything works with old CPU and your bios is upto date. Did you buy it new?

weird, i bought an ASUS b85 board a few years ago and dropped a 4th gen i7 into it with no issues, not BIOS update needed. I'll be surprised if you do need a bios update unless your board was sat on a shelf for years before you bought it. Do you have another LGA1150 system to test the i5 in ?

@Zackiz Make sure to close or unplug the PSU and to reset the CMOS, either with the jumper or by removing the battery for >10 seconds.

Thank you for the answers.

I have now:

-reset the CMOS by removing the battery, no change.

-followed that helpthread linked

 

I'm going to look into the BIOS again but if that doesn't work. Should I consider the cpu busted?

 

I bought it new btw, as the answer to a question above.

Sorry to dig up an old thread but i'm doing the same(ish) but with a used CPU. Same board a B85M-G trying to put the same i5-4690k from an I3-4130 (which if you put back in works fine). Updated BIOS, Cleared CMOS, still no sign of life from the processor. All fans spin up, board is fine.

so what version is your bios now?
