Computer turns on, Monitor receives "no signal"

[Known Scone]

Hey, I'm a first-time PC builder. As the title says; my newly-built PC turns on and stays on just fine. Yet, the monitor I have securely plugged into the Video Card's DVI-D slot simply receives no signal when the computer is on, thus sending the monitor into power-saving mode. Before my in-case build, my computer was displaying just fine on a out-of-case build.

I've tried multiple things:
- Resetting the CMOS by taking the battery out for 5 minutes.
- Reseating the Video Card.
- Unplugging all of the plugs that weren't included in the out-of-case build.
- Checking all of the plugs on the motherboard.
- Trying two monitors, with both DVI-D and HDMI.

I've also had other problems, which may or may not relate to this problem:
- LEDs do not light up on the front of the case, where I assume they are supposed to.
- Reset button (I've tried twice) does not appear to work either.

did you also plugin a 2nd cable from the psu into the motherboard? take the video card out & plug a working monitor into 1 of the onboard video ports.

What do you mean the 2nd cable from the PSU to the motherboard, I assume you mean either one of the two cables I plugged in, the 24 pin one and the 4x4 pin one (in the top-left corner.) Regarding taking the video card out and using the mobo ports for the monitor, that didn't seem to work.

Any other suggestions ;D?

yes on those 2 cables. disconnect all cables to drives. remove all ram except for 1 stick & reseat it. remove all cards including video card & use onboard video. disconnect the power cord from back of computer, reset the cmos again & reconnect the power cord. turn on the computer if still no post then try another psu for testing purposes to see if yours is good or bad.

I found the... problem? I dunno, maybe it's just one of the problems?

That's strange, the problem that I found should've been causing a short this whole time. Yet, only today the computer started shorting, restarting over and over, I searched all over for the cause, finally checking the CPU. And boom, the pins are bent, which is the strangest possible problem in my circumstance, since the only time I've ever put the CPU in/out was at the start of the out-of-case build (out-of-case-build was displaying) and right now (when I've found the problem.) I'm now starting to think that bent pins aren't the only problem my system has, needless to say- I'm getting a new motherboard.

One question: do you have any possible guess to why this may have happened sometime in between builds please (too much pressure when putting on heat sink fan)?

I hope I don't find this problem come up again, maybe it will remain if I keep the same PSU/CPU- needless to say, I'm in need of a new motherboard.

is not to much pressure by the heatsink as those bent pins are not in 1 are but scattered over the socket. if you did not touch those pins at all then when you bought that board, the pins where already bent. the store I get my computer stuff checks for bent pins before the board leaves the store.

I ordered mine from amazon, so I'm not sure about any quality-checking policy. Just wondering, do you think I'll be able to get a replacement through a warranty on my motherboard?

 

[ffg7]

try it.
