    Not sure if your problem is related to a monitor, video driver issue or something on the motherboard.

    By the way, I also get a "NO SIGNAL" message on my monitor LCD panel when I shut down the PC and leave my monitor still turned on. Before I boot up the laptop, I also turn on the monitor first and it also shows this same message. After the laptop boots up, the LCD message, of course, is replaced by the standard video information (horizontal, vertical refresh frequencies, etc.).

    Follow up the consensus seem to blame video card. So I opened the computer, then opened fan an heat sink cover,and to my surprise heat sink fell out.Plastic mount was broken.To test if that was problem I laid tower on it's side and placed heat sink in so it couldn't fall out turned on computer and every thing worked fine.I guess that was cause Waiting for new mount. Thanks for your help.

    Glad to hear that. Remember that heat is the worst enemy of your computer (yes, even worse than malware). ;)
