No onboard video for first boot?Follow

I finally got the parts for my computer, and I thank everybody in that thread I posted for your help. I think I've put it all together correctly. The problem is, the motherboard I have doesn't have onboard video. I do have a video card, but when I boot I'm getting absolutely nothing out of my monitor. I currently have a slightly older monitor connect through a DVI->VGA adapter that came with the card.

It seems as though I have everything plugged in correctly. The cpu fan that is plugged into the motherboard is spinning, as is the fan on the video card. I'm pretty certain I have the card in the slot correctly, I've removed it and re-placed it twice now just to make sure (while making sure not to damage anything.) I'm really not sure what to do now.

double check everything is plugged in properly--especially slotted items. One big offender is the memory cards--even though you hear the locks click, sometimes they still aren't seated quite right, or there could be oxidation preventing a clean connection. Pulling them and putting them in again often magically fixes things. Also, make sure the video card is properly seated. Sometimes if the motherboard is just far enough from the edge, when you tighten the ***** to hold it in place, it makes the card shift slightly and some pins loose contact at the other end. Fixing this takes a little creative remounting sometimes--might have to bend the bracket slightly or something in the long run.

Other things to check for is jumper configurations for the motherboard--especially in regards to the CPU. If there is anything for selecting anything CPU specific, make sure it is set right according to what you are installing--this feature is getting more rarely used, but you never know. Also, depending on the CPU you have, you might need to connect a small 4 pin connector (two pairs of black and yellow wires if I remember right) to a motherboard connector near the CPU socket. A lot of people overlook this connection. Newer video cards may also have a similar looking power connector as well--but it will be laid out a little differently, so you won't be able to plug the wrong one in the wrong slot.

If all else fails, try resetting the BIOS. This should be covered clearly in the manual for the motherboard. It's usually a simple process of powering down completely, moving a jumper from pins 1-2 to 2-3 for a few seconds, then moving it back. That should set everything on the motherboard back to either auto-configure or the slower speed settings to make sure it boots with just about anything you may have in there, then you can go into the config and adjust it for your specific CPU and memory and such.

Woo, got it! While none of those things were explicitly the problem, I was reading through the manual again and realized that, while I had plugged in the 24 pin power, I hadn't plugged in the EATX 12v. Thank you for your help!
