New cpu, computer won't even post.

[ZebastianAnd]

So I have this old desktop with a Asus P8H61-M LE/USB3 motherboard with bios version 0803 and a Intel Pentium G630, powered by a Chieftec iARENA GPA-350S 350W powersupply. It has successfully been running ubuntu server for the past year or so. I decided to upgrade the old cpu to a "new" from ebay, Intel Core i3-3240. Recived the new cpu and installed to the motherboard and tried turning it on. The fans spun up, power led on the front also turned on, about 2-3 seconds after first pushing the start button everything stops for another 3 seconds before starting all over again. Going through this cycel until i pull out the power cord.

 

I've tried reinstalling the old Pentium, then it works fine. Anyone that has a clue of what I could try would be very appreciated! Thanks.

Put the old Pentium back in. Download the latest BIOS for the board from Asus which is 4601 and it'll work. 3240 isn't supported until BIOS v3605 and 4104 depending on the revision.

You need at least BIOS 3605 or 4104 depending on board revision. Update your BIOS to the newest with the old working CPU then try installing the new CPU.

your board doesn't have support for that cpu until at least bios version 3605 , update the bios

Edit: other people were right only certain BIOS versions supported this CPU. That's what happens when I view a support page from my phone. I miss the BIOS version area XD
