No Signal When I turn on my computer the monitor says Acer and then it has a little box that says "No Signal". It then goes black.

There must be a connection problem from monitor to pc, check the pins to see if any are bent in the plug to the pc. If it is a seperate graphics card, check that it is seated correctly in the agp (brown) slot and not come loose. Try booting in safe mode (F8) on boot and select boot Windows in safe mode(this will run pc with normal vga driver and not the graphics driver), and see if it stays on, if it does it is a graphics card driver fault, so re install.

If there is no display on the monitor, then your computer is not sending a video signal to the monitor.
This could be caused by a bad video card or some other hardware problem. I would open the case and disconnect all the devices (hard drive, CD, etc. Leave only the CPU, memory, and video connected. You could leave the keyboard and mouse connected too.
If your computer then starts, you can start to add devices (after turning the computer off) one at a time.
If this doesn't work, then you are looking at replacing the motherboard or just the video card if that is possible.

Make sure the cable to the PC is secure by tightening the screws on each plug. If the problem still exists then you need to take it back to the shop where you bought it from. It could be a fault graphics card or connector.
