Monitor wont display anything after installing my I7-3770k. I switched back to my old cpu and everything was working fine. Then I tried updating bios and clearing cmos by removing battery, still same results. Also tried removing graphics card and using the built in display but nothing works. I double checked and know the cpu is compatible with motherboard. Any help would be amazing.
 
What CPU did you replace the 3770K with? Are you sure the replacement is fully functional in another motherboard?
 
List your full system specs please.

I think it's dead. Just like when my Athlon T'bird 1.3 got damaged, because I rushed a heatsink installation, back in October, 2002. Mea culpa, for me!
The symptoms for me were the following: It would power up, but nothing else happens. (nothing other than fan, HDD spin and LEDs)

I5-2400 im kinda new to this pc stuff but I checked what socket my motherboard has and showed this core was compatible.

If you have a H61/H67/Z68 board, you need to get a BIOS update first to gain compatibility with Ivy Bridge CPUs, because the 6-series boards released with the Sandy Bridge (2000) CPUs. The two CPU families are pin compatible, but BIOS support needs to be there.

If the board maker's website says it's compatible, it probably means there is indeed a BIOS update for your board that provides compatibility with Ivy Bridge, you just have to flash the board with it.

If you have a prebuilt, chances could be that the OEM never made a compatible BIOS revision for your board, and it does not and will not support Ivy Bridge. That seems to be the case with the Dell XPS 8300 desktops. There was an experimental BIOS floating around for Ivy Bridge support, but it was never officially released by Dell.

Did you bend any pins in the socket the 3770K went into? Is it a Z77 mobo?

Dont think so and how can I tell what motherboard it is

I feel dumb asking this but idk where to find what board I have but I have a prebuilt optiplex 790 if that helps.
 
That has an Intel® Q65 Express Chipset. Not compatible with a 3770K and even if it was it'd be a total waste of time, money and effort because the Q65 isn't overclockable. You want a Z77 with a 3770K to get the most out of the CPU.

Yeah that's a prebuilt. Dell has internal identifiers for its boards but doesn't put the name on the board. Don't sweat the name, all the drivers and firmware are available here:

Support for OptiPlex 790 | Drivers & Downloads | Dell Canada

It looks like the latest is the A22 BIOS from 2018.

Unfortunately, there's a lot of threads out there stating that the Optiplex 790 can't take Ivy Bridge CPUs because of its Q65 chipset (a "professional"-grade chipset). Not sure how exactly Intel locked out that one, but that's the consensus. I'm afraid there's not much you can do except try to find an i7-2600.

Even if it supported Ivy Bridge, the 3770K is a bit redundant over the 3770. There's no overclocking available to you on that Optiplex.

Its fine, ill see if I can somehow return. Thanks for letting me know at least so im not wasting any more time on this.

Ill look into that z77 thanks.
 
Since you already have the 3770k I'd put a Z77 motherboard in it. Your best bang for the buck would be an ASRock Z77 Extreme4 (I have one still in use with a 3770k in it).

Would I have to worry about if it fits or no

The Z77 Extreme4 is a standard size ATX mobo. No idea what size the board in your OptiPlex is. You'll also likely have to change the PSU and the front panel connectors are different but easy to mod.
