Monitor not receiving signal from MB

Hello everyone,

I recently bought components to build my first tower on my own. Other than a few minor hiccups, and nothing happened like static from what I could tell, i was compulsive about grounding myself on the PSU. After testing it out for Fan operation I decided to hook it up to my monitor to hopefully work on installing Windows. So far almost every power-up has begun with a 2-second power-up, quick shut-down, followed by another power-up that stays powered on.

I can't get a signal to my monitor. I know my monitor works because I am using it on my older PC, but when I plug either the VGA cable or a DVI cable into my new comp's MB the monitor goes to sleep...

I have looked at multiple FAQs and guides regarding installation and normal troubleshooting solutions for this kind of problem but to no avail. One thing I have to fix when I get home is the Mount for the heatsink and fan, I turned the clips (or whatever they are called) the wrong direction... but I don't see how that would explain this problem...

Another concern I had was the SATA cables from the SSD HDD, and DVD drives being in the right ports, but I also don't think that would explain this problem...

The only other things I can think of are my video card not being in correctly, being in the wrong PCI slot, not being compatible with my MB, or I fried an important component at some point.

Please I have spent a lot of time trying to figure this out and would love some help. Also I tried taking out one and both RAM sticks...

it really dosent care what port your sata drives are plugged into

my first guess, have you tried both your gfx card and your onboard gfx?

ok from my limited wealth of knowledge I believe it is my gfx card. I was able to get it to BIOS and install windows with the gfx card out... and also with it in and only 1 6 pin power cable...(a bad idea?) when both 6 pins are in, I cannot get a signal to my monitor though...

Should I try a different slot? I think I have 3 available...

yes try a different slot, and make sure there both labeled PCI-E just in case

Ok so what I did was leave it in its slot, in BIOS I went to advanced mode and under Onboard Devices Config I was able to change PCI Express X16_3 slot (Black) bandwidth from Auto mode, to X1 mode, which occording to the MB manual is the only mode which enables all slots...

My card is plugged into slot 1... does this mean its getting reduced performance? After doing this change though, I was able to plug in the second 6 pin power cord, and get it to load with the DVI cable in the video card port! Yay!

I finally determined that in BIOS I needed to set my PCIe3 slot to X1 instead of auto... according to the manual Auto and X4 for this PCI slot mean that PCIe1 and 2 are disabled. The manual recommends though for a VGA card of x16 to be placed in the PCIe1 slot... but from what I can tell this means I am not getting full speed since there seems to be a discrepancy in the manual regarding the slot to use for optimal performance.

And Ironically the Black slot that would solve this problem is too close to the bottom of my motherboard so my graphics card cannot fit in that slot... Is there a way to tell if I am getting reduced performance from the slot its in?

2 x PCIe 3.0/2.0 x16 (x16 or dual x8) *1
1 x PCIe 2.0 x16 (x4 mode, black) *2

according to this the top two are pci-e 3.0
that may be the issue

can you elaborate? That whole thing confused me and I'm not sure how to determine which my gfx card should be or is compatible with...

hmm, well i was thinking that because the top 2 pci-e ports are 3.0 it might cause complications but that dosent seem to be the case... is it possible for you mobo to be mounted higher?
