[SOLVED] Why won't my pc POST ?

[NolanB]

Recently I upgraded to lga 1150 with and i7 4790. However I've tried numerous fixes but the pc won't post. In contrast when I try the older cpu(i3 4130) the pc boots normally. I also replaced the 4790 for a new one with the problem persisting.

CPU:i7 4790
GPU:Rx 480 8gb
MOBO:H81m-e Asus
Windows 10 64 bit
8gb ddr3 1600mhz
2 wd blue Hdd: 360gb, 1tb
PSU:Thermaltake litepower 650w, 80+ bronze

It needs BIOS version 0808 or higher to support that cpu

More information needed:

Operating System

Disk drive(s)
PSU

When boot fails: any beeps, diagnostic LED's

Does the following link provide the User Manual applicable to your Motherboard?

[Verify that I found the correct User Manual.]

Refer the to User manual to:

Post was edited, thank you for the notice. no beeps, led's work, fans spin. all components in theory should be supported, everything is correctly installed. i will double check that the bios is properly configured.

Remove gpu, remove the hd that does not have os on it, use only one stick of ram if you have two or more sticks, then try to post to at least bios.

Found this--------> *Before using the new Intel 4th Gen Core processors, we suggest that you first download the BIOS updater for new Intel 4th Gen Core Processors and then update the BIOS using this tool to 0703.

When the motherboard has a BIOS chip, it may peel off over time due to thermal expansion and cause the computer to issue an erratic POST.

Did you update the bios with the old CPU I3 in place?
