Help my pc won't post.

[LordofDeath98]

I just upgraded my CPU from a i3 2100 to an i5 3470 and now my Pc won't boot. It just powers on and stays like that. It dosent output to any displays on either my igpu or dgpu. It doesn't even power my keyboard. Is this a dead Cpu or have I broken my motherbord as it was working fine before. 

All of the fans power up and the hard drive light stayes on for about 13 seconds before turning off.

 

Edit: My motherbord is a Biostar H61MLV3 v8.0

Try clearing CMOS?

If you have a 6 series chipset, you need to update the BIOS to support Ivy Lake processors if you haven't already.

Yep. Try updating the bios. I had to do that with my z87 board. Which I had to purchase a cheap cpu to do mine.

I've done that also the motherbord has the latest BIOS version.

If plugging in the Sandy Bridge processor allows the system to run just fine, either the motherboard actually does not have Ivy Bridge compatibility, or the Ivy Bridge processor is bunk.

Try switching back and if it works, CPU is busted. If not then the MB probably bricked on the update

The motherbord does support Ivy Bridge as is is listed in the supported cpu section on biostars website. http://www.biostar.com.tw/app/en/mb/introduction.php?S_ID=724#download

 

Will reinstall the Sandy Bridge CPU tomorrow to validate it is the CPU. 

 

Good job the comany I brought it off ofers a 30 day warranty.

I updated the BIOS before I bought the Ivy Bridge processor as a precaution and it worked fine

The thread was moved to the Troubleshooting section

Yes, I'd say it's most likely the CPU at this point if the BIOS was upgraded and CMOS was reset and everything. Will know after you plug the i3 back in hopefully... you didn't change anything else in the system while you were upgrading the CPU did you?

Thank you all for your help. I have determined that the CPU is faulty. I will send the CPU back and buy another one, hopefully I will have better luck the second time round.
