Problem with Acer-X203H monitor

[jon the noob]

Hello, I'm having a problem with my monitor. When I boot my PC, I see the bios screen along with other various load up stuff. I see the windows logo flash as the operating system loads (telling me that the screen is receiving signals from the HDD and motherboard) but once the computer begins to log me into my username, the screen turns off. If I try to turn it on, it says "No signal" and then shuts itself off again.

This is a problem that developed suddenly (overnight, actually). Any ideas?
