    Windows 8.1 Startup problems: no signal/freezes


    Hello everyone. I'm having problems with my PC. When I try to start the pc, most of the times the monitor shows 'no signal', but the pc is running (all the fans are running and the lights are on), but the lights on my keyboard (Caps Lock) and Mouse (I have a mouse with a light indicating the current 'mouse speed') are off. All I can do then is turning the pc off manually (by holding the power button a couple of seconds). Other times, when this doesn't happen, Windows freezes on startup (black screen, or while showing the windows logo) and sometimes it shows the windows loading screen, and then loses signal afterwards. Sometimes, it restarts automatically while having no signal, but then the same problems occur again. Other times, it loads the startup repair. In startup repair, when I click 'Continue to Windows', the same problems occur. When I eventually get it working (by manually restarting numerous time until it works), a lot of times it also freezes (and sometimes random restarts) while already using Windows (for instance, watching a video file, watching youtube, playing a game or whatever).


    A friend of mine built this system for me in April this year. At that time, I installed Windows 8.1 on it, but I got about the same problems then. When I installed Windows 7 instead, it worked without any problems. I bought an SSD last month, and I installed Windows 8.1 on it, but now I get these errors. Because of this, I think it has someting to do with Windows 8.1 (maybe compatibility issues with my hardware?) but I'm not sure. I really like Windows 8.1 and I'd like to (try to) fix this, and have the Windows 7 install as a last resort solution.


    Also, sometimes the programs I'm running (when I'm able to start the pc normally and not crashing, which is maybe 5% of the time) are not responding. At those times, I can move the mouse freely, but the programs show 'not responding', and the desktop isn't responsive as well. I would think that a system like mine would be able to run without such flaws.


    I also have a watercooler installed (Corsair H80i), but it makes a lot of noise. I've managed to reduce that noise by using the 'Quiet Mode', but when I start the pc, it still makes a tremendous amount of noise, because it is testing the fans (Power On Self Test?). Is there a way to disable this? This question is just a small one and has less priority than the problems of my pc!


    I hope someone can help me with my problems, because I really want to use my computer to its fullest without any problems, since I paid a lot of money (>1.000EU, which is a lot for me) for this pc. I've had a lot of problems since I had it, and to be honest, I'm getting pretty worn out.
    For anyone responding to this thread, thanks in advance!


    Here are my system specifications:
    MSI 990FXA-GD65 Motherboard
    G.Skill SNIPER Series 8 GB RAM
    Seagate Barracuda ST2000DM001 2TB HDD
    MSI R9 270X GAMING 4G GPU
    AMD Black Edition - AMD FX 6350 CPU
    Samsung 840 EVO Basic 250GB SDD


    tl;dr
    Problems with pc: no signal monitor on startup, freeze on startup, freeze while using, random restart while using. Maybe it is caused by Windows 8.1 compatibility. Help needed.

    Can you restart your computer whilst holding down SHIFT?
    This should give you the Option Menu.
    Click on Troubleshoot, then Advanced Options, then Command Prompt.
    Type in sfc /scannow
    This should clear up any problems or at least indicate if there are any.

    Thanks for your reply.
    I ran sfc /scannow a couple of days ago, but that was in the command prompt in windows itself (and not in the Troubleshoot/Options Menu). It showed no errors. Now when I enter the Options Menu like you said and go to the command prompt, the pc restarts (is it supposed to do this?). And then it opens the command prompt ("Preparing Command Prompt"). But when I type sfc /scannow, it says:
    "There is a system repair pending which requires reboot to complete. Restart Windows and run sfc again."
    I've tried restarting and retrying it, but it shows this message everytime. Sometimes the screen loses signal or freezes, so I have to start my pc again and enter Options Menu again.

    In Admin Command Prompt type dism /online /cleanup-image /restorehealth
    You can cut and paste the above.

    If you have no signal to your monitor, and your keyboard, mouse, or anything isn't initializing correctly, I'm suspecting a bad motherboard.

    How many RAM sticks do you have?

    One thing I do first to test for a faulty motherboard, is to remove all ram sticks. When the RAM sticks are out, the Motherboard will beep right when you turn it on.

    If the motherboard beeps, hold the power button to shut it off, and insert one of your RAM sticks. Try to boot the computer. If it boots normally after a few boots, take the stick out and test the other one, if that one works and has no problems, then its running fine in Single Channel Mode. Then insert both RAM sticks in the machine. Make sure the RAM sticks are in the right slots to enable dual channel mode. If the computer doesn't boot or doesn't post, then there is a possible faulty motherboard, as it won't run both sticks.

    Now if it has problems even with one stick of RAM, it could also be bad RAM sticks.

    I thinking its either faulty RAM or a bad Motherboard.

    Turn power OFF completely when changing any parts like RAM etc. MB receives power even if shut off at the Start button. Failure to do tha may ruin components and/or MB !!!!

    Result: "The restore operation completed successfully. The component store corruption was repaired. The operation completed successfully.
    But after this, the problem was still there. Here is a screenshot:

    I have 2 RAM sticks. I removed all the RAM sticks and started my pc, but the motherboard didn't beep.
    I inserted each RAM stick individually, and both of the times, it worked. But when I insert them both, it works as well. My problem is not that it has no signal all the time, just most of the time. Sometimes it still works and I can still start my pc normally (but then, most of the time, it freezes afterwards).

    Thanks for the heads up, I turned off the power by switching the power button of my pc (the one on the back, with the 0 and 1) and removed the power cable. After that , I removed the RAM sticks etc.

    It could be any number of different hardware problems such as a loose connection etc. though the fact that W7 works perfectly suggest otherwise
    As a matter of interest what anti-virus are you using?
    The reason I ask is recently I could not open Internet Explorer using either the latest paid for or the free version of AVG.
    On uninstalling AVG everything returned to normal.

    When I built the pc (april last year) reinstalling W7 made everything run fine, but now when I install W7 it has the same problems as mentioned.
    I recently did a clean install of W8 (couple of days ago), so it doesn't have an antivirus.
