Jun 12, 2012My first guess was that since we have an electrical instability in our home, perhaps the uneven flows of power would sometimes send a false signal to the power unit of the computer and trigger a start-up (quite often the lights in our home will briefly, and sometimes violently, wave up and down, especially at night).

Jan 1, 2013Okay, so a while ago I finished building my new Pc. It was working fine for about 3 days but then it would randomly go black and show the message, "Please select a proper boot device and press a key". Prior to this I had accidently been turning off the power to my computer (it was in a weird position, so when i stretched i would kick the cable). Could having turn off the power caused this? I only did this twiceI also tried connecting it to different sata ports and nothing
View 7 Replies View RelatedComputer Turns On Back When Hibernate
May 6, 2011I am having a problem with a new installation of Windows 7 Home Premium. I have always liked the Hibernate feature and used it extensively when I was running Windows Vista Ultimate. Since installing Windows 7, whenever I run Hibernate the computer turns back on. When I used Hibernate in Windows Vista Ultimate I knew that the programs that I left open would be where I left off when I restarted the computer from Hibernate. Now, it just seems to turn on when it wants to. I am sure it is a setting in the Power Settings category in Control Panel. I'm just not sure how to set.

View 6 Replies View RelatedComputer Won't Shut Down, Screen Just Turns Off
Nov 20, 2011Turns out all my problems were an aged battery, according to the tech shop who reinstalled windows after some deeprooted viruses. But now my laptop won't shut down all the way, but the screen turns off. The keyboard's LEDs stay on, and the fan keeps blowing. It stayed that way for at least five minutes, between me getting a snack and coming back. I don't know if they reinstalled from the disc that shipped with the laptop or gave me a knew windows 7, but this particular issue only started when they reinstalled the OS.

Nov 21, 2011I thought this was a problem only when I had my monitor switched to 120hz because it turned off alot back when I had it on, so I had been playing with 60hz for a while and tried my luck turning it back to 120hz, worked for a few days but now it seems it cant handle it, even in 60hz. It's a newly built PC!I have checked graphics card with Furmark and no problems there, ran memtest overnight, passed tests. I cant upload any minidump files because it is empty.

Jul 3, 2012Just got myself this (old) new computer, that I was going to use for a media center. But it randomly crashes, and i can't seem to figure out why. I formated it yesterday, so I doubt it would be a virus.Sometimes it goes black, and picture returns within a few seconds, but other times it freezes up completely. When I restart it (with the power button) I cant get pasted the BIOS screen, but if I unplug the power supply, and hit the power button a few times and then plug in the power, it starts up like normal. (does that make it a RAM issue?)Freezes have happened doing the following: Using XBMC (both in menus and while watching a video), while Internet Download Manager was running. While file transfer was running, and a few times while i wasnt at the computer.Specs:Windows 7 Ultimate x64ATI Radeon HD 5670Intel Core i3 CPU6GB RAMPhillips TV (Connected with HDMI)

Aug 31, 2012My computer will randomly turn off. Only if I am using it. I can turn it on and it will sit forever, but if I use it.Shuts completely off with no warning, no error, nothing. I need to power it back on by pressing the power button. I went to CMOS and turned on restart on system failure and it does not restart. Don't think it's running hot.. at least, my gcard is only doing 48 C which is low. Idk if it's a software issue or hardware?I ran a scan of my computer using ESET NOD32 Smart Security = nothing found.

Mar 7, 2012I was playing around with Task Scheduler to turn on laptop at specific time, it works great. However, while the system starts up just fine, the screen remains black until I touch the mousepad.Now that doesn't seem like a big deal, but what I was experimenting with is having the computer turn on so I could use TeamViewer app on my phone to access my desktop when I'm not home. Problem is, TeamViewer won't access desktop if screen is black and if I am not physically present, I can't tap the mousepad
View 1 Replies View RelatedComputer Screen Turns Off After The 'Starting Windows' Animation
Jul 23, 2012I have an MSI a6205 laptop, and have recently reformatted my computer to reset everything in it. My problem is this: Ever since I re-installed Windows 7 my computer has been starting up, getting to the little 'Starting Windows' animation, then the screen turns off completely, with no back light (the fans and LEDs still function perfectly). The way I have been getting it to work is by turning it on, waiting for the screen to turn off, then tapping the power button and putting it to sleep, after a few seconds I hit the power button again to awake it, and the screen turns on and functions perfectly.
I know this isn't a hardware issue, because I also have Ubuntu 12.04 installed on the machine, and it works perfectly. It's just Windows 7 that is giving me this problem.
