Hello,

My dad and I put everything together for my new PC and everything seems to be running fine. The H80i lights up and the fans come on, the graphics card's fans are spinning, the case LED's come on, but nothing comes on on the monitor. It just says "VGA - No Signal." I tried hooking it up via HDMI and via VGA and got the same result each time. I've tried reading through guides on how to fix that but they didn't seem to apply. I would definitely appreciate any help.

Thanks.

If your mobo supports integrated graphics and you have installed an add-on graphics card, make sure you're plugging in to the correct VGA or HDMI port: you need to plug into the one on your graphics card, not the one on the mobo.

If it posting some new mb have the mb ipgpu as the first boot device. Things that can cause no post but system has power. Old bios that has bios bug with the gpu...if there onboard video try pulling the gpu and posting.
Old bios and new CPU. The mb will be missing the boot code to post with the new CPU. Look at the mb CPU qal list check the needed bios rev to post and check to see if your mb has the newest bios rev. Some asus mb have USB bios updates that you can update the bios from a USB stick and stand by power. Check that the CMOS battery on tight and the CMOS clear jumper on the right pins. Try posting with one dimm and make sure the four or eight pin power plug on the mb edge is connected. Check for dead shorts, bent USB pins or missing a row of pins or placing the reset cable on wrong or having reset button stuck. Other issue can be mb io shield short or mb grounding out to mb tray do to missing standoffs or CPU heat sink back plate shorting to the tray or back of the mb.

Haha, I feel pretty dumb. Yeah, I plugged it into the MB. I tried HDMI on the graphics card originally and that didn't work, but that was because I couldn't change the monitor input at that point. By now I have everything hooked up and it looks great. Thanks for the help. :)
