First off, this is my first post on this website, it was recommended to me by a friend. Sorry if I'm in the wrong section, or don't provide enough information.
My computer is a HP Pavilion, and my monitors are a HPw2408h and a Phillips 170B (I'm not sure if this is relevant)
Quad core GHz processor,
The problems started about a week ago, I booted up my computer like normal, but it didn't come on. I could hear a loud whirring sound, and my monitors couldn't detect a video input. I performed a hard shut-down, then rebooted it. This time, only one of the monitors came on. The resolution was far lower than usual, and all the aero features were off. I had a look round the computer, and in the device manager section it said 'this device is not working properly' next to the graphics card.
I checked online for solutions, and decided to uninstall then reinstall the driver. The uninstalling went fine, so did downloading the driver again. However, it said I needed to restart my computer. I did this, and the same thing that happened earlier happened again, a loud whirring sound and no video input detected. Now whenever I turn the computer on I have two options:
Launch Windows Startup Repair (which doesn't know how to fix it)
Start Windows normally (which leads to the whirring sound and no video input)
I'm at a loss, I'm usually half decent with a computer, but I'm totally out of my depth.
Any help would be highly appreciated, and again I'm sorry if this is in the wrong section.
