    Does the screen come on for a few seconds and then go black? It could be the machine is failing to post which could indicate the motherboard is shot.

    I code C hash-tag .Net

    I think u check out your machine with any good computer expert. They solve out your problem.

    How would you know if your keyboard and mouse both aren't working if your screen is black?

    I have no idea if I'm insulting your intelligence here but have you tried a simple CMOS reset, removing any overclock set (CMOS reset will do that for you), removing all sticks of ram bar 1 just to test for a dodgy stick?

    If your screen doesn't turn black until you actually hit into Windows that it's most likely some sort of malware / virus, which in this case you may have to revert to a re-install.

    You could also try and RDP onto the machine through another machine to see if it's actually still alive or if it's actually frozen.

    If you could post back more precise information maybe I can help pinpoint your issue a little better.

    We have this problem with my wife's machine. Culprit is the video board: It draws enough power that it causes the power supply to go into overdrive mode.

    *SOMETIMES* this sequence happens late enough that the machine has booted and a brief overdrive is okay. Other times, the overdrive occurs too soon and the machine won't boot. Screen stays black.

    Verify if the keyboard is enabled to wake the computer out of sleep mode.

    a) Open the Keyboard control panel item, as described in Method 1.
    b) Click the Hardware tab, and then click Properties.
    c) Click the Change Settings button

    Note This step requires Administrator access
    d) Click the Power Management tab, and then verify that Allow this device to wake the computer is enabled.
    e) Click OK, and then click OK again.

    Else go to the website of your system and try to read out the their explanation regards mouse and keyboard care.

    The same problem happened for me also. I changed my keyboard and monitor once. Now again it started. That time they told it happening because of keeping key board guard during the winter season and rainy season. Then I removed. Daily I am using minimum 2 hour. Then also it happened again. I don't know the reason

    I'd be interested as well, I have a wireless combo, but don't know if it would be same correction, I am sure it must be a windows registry key as it was to make the IR Remote wake the PC,, just need to shut off the mouse as my kids always wake the PC and I always forget to shut off the mouse.

    I confirmed the problem. It was just about the failure of mother board i think so. So, If you change the motherboard then your problems will be get solved.

    I also have encountered that problem. Motherboard is the problem when I consult a computer technician.

    Despite the above... its almost ALWAYS a software problem though power supplies can be the culprit as well.
    You need to check if the machine is failing to rise from sleep or hibernation, if (and it probably is) hibernation, disconnect from the web, disable your AV, let the machine hibernate and see if it wakes then, if not do a search for sfc /scannow & reset your power settings to defaults in the control panel.


    At worst a fresh install will probably cure the problem, if not then indeed you may have a hardware problem... that said please note that 'its the motherboard' is often a technicians way of saying, `we don't know whats wrong`
    You should also test your RAM and Hard drive for errors, search for memtest and the appropriate testing tool for your hard drive (e.g. seagate seatools) before you go replacing your motherboard.

    May be it because of motherboard complaint. I had this same problem and I solved it by changing the motherboard
