[melonade300]

Hello everyone, I leaved my computer overnight then in the morning i move and press the space bar for the display to wake up but it didn't. I already set my computer to never sleep and the power option to high performance. Then I restarted my computer in hoping for the problem be fix but it didn't show any display, it just booted up with the windows 7 start sounds. I remotely controlled my computer using remote desktop connection and check the video card and other PC parts but it didn't show any problem and I open GPU-z then I notice that some of the values are marked "unknown" the device manager even says that my video card is working fine. Please help. Sorry for my bad English.

have your tried boot the computer into safe mode?

Earlier this day I successfully booted the computer with the display on with the monitor plugged in to the video card output and i restarted the computer to boot to safe mode and it didn't show any problem. Then after that I decided to play basketball so I basically turned the computer off then when I get back and turn the computer on, the problem happen again. I then again check the computer remotely since it didn't give any display at all, it shows the video card working properly.
