I realize that they're incompatible, and I know that you need to be able to have the right processor for the computer to work, but my question is, if my monitor is not getting a signal from the computer, but the computer is powered on... is it because I don't have a processor that is compatible inside? I realize that it wouldn't work in the first place, but is that what I should expect when I don't have a working processor inside?

LGA 1155/ LGA 1150 are diff
1. 1155/1150 are the names of the compatible Chip-set you will need the mobo to have, so make sure your mobo is compatible to the cpu's Chip-set
ex. mobo GA z87x UD4H is compatible with 1150 Haswell cpu's (i3/i5/i7) but not to the Sandy Bridge Cpu's!

I don't think you've given us enough specific information about your system to be able to help much.

What specific brand and model are your motherboard, memory, CPU, and graphics card?

Not necessarily. No monitor signal could be a number of things. Video card related, monitor settings related, among other things. Assuming you have compatible motherboard/processor, your best course of action would be to test the parts in a known-working computer. Swap the video card into a different computer and see if it will give you video. Use a different monitor and see if that produces an image. Etc. Etc.

MSI Z87-G45 Gaming LGA 1150 Intel Z87, Cooler Master Hyper 212 EVO
GTX geforce 760
i5 quad 3.1 ghz LGA 1155 Ivy
750 W PSU
10 gb RAM

The thing is, when I didn't realize they weren't compatible, I had it in the socket, and the PC DID have power and the fans ran etc, but the monitor had no signal, I just want to know if that's what could have been the reason for my monitor not having a signal, and I think rgd1101 has confirmed that for me.

man, if you somehow forced an 1155 cpu into the motherboard, that cpu is likely ruined due to broken/bent pins... and possibly motherboard damaged as well


you need a new cpu and motherboard, and make sure they're the same socket this time.
