    Hi, I just finished building my first computer. In a test boot when it was first finished I got some info across the monitor, but now when I have it all hooked up and ready to have Windows 7 installed on it, it decides to quit on me. When I turn on the computer and monitor, the computers LED's and fans work but the ASUS monitor just gives me the ASUS logo then says VGA No Signal. I get no info even though it worked in the test boot. I tried most of the tricks to get it working but none of then worked. I need advice as to wether it is internal, with my hookups, or the monitor etc. If anyone has seen this before please tell me what to do.

    Hi Zerple, Welcome to PCHF!

    Open up the computer and check all of the power cables that are connected to the motherboard and the video card. Make sure you have the extra 4 or 8 pin power cable connected to the motherboard. Does your computer have a system speaker hooked up to it? Do you hear any system beeps? Have you made sure that all your components are compatible?

    Does your motherboard include an integrated video card?

    Also please enter your System Details. It helps us in answering your questions, thanks.

    Thanks a ton Evan! This is a great forum!
    All my power cables are connected and I have just reset my CMOS. It seems that it still doesn't work. I have a graphics card installed. However, my motherboard has onboard graphics, so I guess I do have a integrated video card. My PC is for gaming so I knew I was buying a GPU and didn't care about the motherboards graphics. Components are compatible. It worked and displayed info when I first booted it up to test if it turned on. I did have some speakers hooked up the second time when the problem started and no beeps. The cables are all connected. My build is from KBMOD without an SSD. This is my build.( I also had some CoolerMaster thermal paste)

    CPU: Intel Core i7-3770K
    CPU Cooler: Cooler Master Hyper 212 Plus
    Motherboard: ASRock Z77 Extreme4 ATX LGA1155
    Memory: G.Skill Ares Series 8GB
    Storage: Seagate Barracuda 1TB 3.5?
    Video Card: EVGA GeForce GTX 770 2GB (Came with free game!)
    Case: NZXT Phantom (Black/Green) ATX Full Tower Case
    Power Supply: Corsair Professional 750W

    All parts are compatible. At first thought my BIOs was corrupted so I reset CMOS but the fans still spin at max speed and it looks like no change. It might be my GPU but I doubt it because a defective GPU would have affected the first boot. Thanks for all your help. This is my first build and I am not very experienced. Not even a teen yet, and this is really confusing stuff. Thanks again Evan!

    Have you taken out the GPU from your motherboard and plugged your monitor into your motherboards integrated video port to see if the computer boots up successfully?

    When you first tested the computer and you said that the machine worked, what other steps did you perform to finish setting up the machine?

    Well thanks for all the help, but I finally relented and got a professional to look at it. I messed up the wiring so now it should be good. Just about to install Windows 7. Thanks for all the help Evan!

    Your Welcome. Do you know what part of the wiring that you messed up when putting the computer together? This way you know what you did wrong and can learn from your mistakes.

    I am not sure which part I messed up. Turns out I needed a VGA to DVI adapter. But now I have the trojan.refroso virus so that sucks. I will post another thread on it.
