I'm new to computers but for the life of me I can't figure out how to get my graphics card to work again.
I bought all of the components for a gaming build computer (new) about a month ago and started assembling the other day. After I put everything together, I installed Windows 7 and shut my computer off after setup finished. Next time I tried to reboot, I get "no display" to HDMI, VGA, or DVI displays.
At first I took the whole computer apart to inspect for damages and loose wires. When nothing was visibly wrong with the motherboard/processor, I reconnected the RAM, GPU, and PSU cables to the motherboard. After searching the forums online for hours on end, I still couldn't find the problem. Next, I took out the video card and let the computer boot with the onboard video card and everything worked just fine. I messed with the CMOS and BIOS settings to allow my computer to detect every kind of card but it still wouldnt detect my GPU. My PSU is 500W, enough to support the motherboard, fans, and GPU no problem. HDD turns on at boot and cd drives work just fine. I highly doubt the GPU is faulty, it worked for the initial boot but refuses to give any signal since then.
Since then I have installed the drivers for the video card I'm using and still no luck. Fans work on the GPU and everything! Just don't get a signal =( Any help/suggestions? I already tried just about every troubleshooter online..
Got a new graphics card and it still does not work. Mobo lights stay on until 4 seconds after POST beep then shut off like before. I've been using the desktop I assembled for over a few weeks now and nothing really SEEMS to be wrong..
