Turned Off Monitor And Can't Turn It On Again?

Nov 11, 2012

I installed the win 8 upgrade on my desktop yesterday. I have two monitors connected but only one of them was working, even though I upgraded the drivers for the graphicscard, I wasn't able to enable the other monitor. This is, however, not my problem.. As part of me trying to figure it out, I hit the "Devices" button in the menu and disabled the only monitor on there. I thought it was the one which wasn't working, but it turned out to be the one already working, so now none of the monitors are on and how to get them working again.

I'm guess that I'm looking for some sort of a keyboard shortcut to enable the monitor again.

Monitor Stopped Responding After Being Turned Off

Aug 11, 2013

Recently my monitor stopped responding after being turned off (after 15 minutes). It didn't happen before. I don't know what to do. Should I disable turning off the monitor altogether? I lose all my work when this happens because the only way to get the laptop working again is to press the power button which restarts the computer although the settings are actually that it should go into hibernation when I press the power button, which it does if the display is working, but if it stops responding it restarts the laptop. No other keys work or do anything when this happens.

Windows 8.1 - Startup Apps Won't Start If Monitor / TV Is Turned Off

Sep 22, 2013

My system os is windows 8.1. I connect to this system remotely regularly. When it is off, I turn it on remotely with WOL and it autologins into windows.

This computer is connected to a LG LED TV through HDMI port.

My issue is, whenever the TV is off, and I turn on the computer (remotely or locally), system boots up fine but the start up apps (those that I have put in Windows startup folder) won't start. As soon as I turn on the TV, windows will start running those start up apps. Needless to say that if the TV is on and I boot into wondows, start up apps start normally with no problem.

Whatever I tried has failed on me. I even tried to turn off windows 8 Fast Startup in power options but it didn't work. I originally had this issue in windows 8. So I installed windows 8.1 hoping that this issue would be gone but it has not. I tried windows server 2012. In server 2012, this issue does not exist and I have no problem with startup apps.

Graphic Cards :: Monitor Shows Black Screen After Been Turned Off Manually

Jun 27, 2013

i installed windows 8 on my new pc who includes Shappire 7870 xt boost and monitor Samsung T220. whether i turned off the monitor manually or it turns off automatic by power saver, sometimes the monitor shows only black screen. The monitor does turns on, it's light turn on, but all i get is black screen.

i also have I5 4570 and Gigabyte GA-B85M-D3H.after i installed windows, i installed the motherboard drivers, includes Intel HD Graphics 4600. Could it conflicts with the ATI's driver?

also, when i connect the monitor to the motherboard it works fine (so far at least). but games doesn't run smoothly.

Monitor Won't Turn On?

Jun 25, 2014

My system (Windows 8) was shut down during a power outage, and now when I try to restart, I hear the CPU go through what sounds like the normal process, but there is nothing on my monitor. I've tried the CPU with another monitor, same issue. I can access the shared folders from another computer on the network, so it looks like everything starts up OK. Before I run down to the local repair shop, is there anything I can try?

Monitor Doesn't Turn Off

Dec 23, 2012

I have it set up just like I did with Win7. Screen saver set for 10 minutes, monitor power off set for 15 minutes. The problem is, the monitor doesn't turn off! To be more accurate, it DOES turn off at the 15 minute mark, for about 1 minute. Then it turns back on and the lock screen shows. Then after 1 minute, the display fades out to black, but the monitor itself is still on.

even disabling the lock screen, but nothing works. I've never been able to get the monitor to turn off for more than 1 minute.

Extended Monitor And Laptop Monitor Not Working

Aug 21, 2013

Today I plugged an hdmi to vga cable into my Win 8 sony vaio, and I plugged the other VGA side of the cable into an acee 22" monitor. I then chose from the right hand windows 8 panel to "extend to monitor", the laptop screen went black, the monitor screen remained without signal (extended screen did not show on monitor) and now the laptop screen is black.

I am now stuck and both laptop and monitor screen not working.

I tried unplugging cable, pressing fn and all the f1 to f12, shift, windows button but nothing is working.

I pressed off button then switched laptop back on and it showed the sony vaio logo on laptop then the screen went black again.

how could I return my laptop screen to work and stop the screen extension which is not working and which I am sure is the case.

Any buttons on keyboard to click at all?

Security :: How To Tell If Encryption Is Turned On In Windows 8.1

Dec 7, 2013

I just purchased a Dell Ultrabook that came with Window 8. I went to the Windows store and did the upgrade to 8.1. I've read a number of articles saying that encryption is turned on by default on a clean install of 8.1 but not necessarily on an upgrade. From some of the articles I've read, I should be able to see whether my device is encrypted on the PC Info page (see attached). I do not believe it is encrypted but I don't know for sure.

I've always used TrueCrypt on my previous devices but won't bother if my new device is already encrypted.

Security :: Windows Defender Turned Off

Oct 19, 2013

It says it's been turned off and it's not monitoring the computer, I can't turn it on either unless I'm not doing something right. McAfee internet security suite was on the laptop when I brought, is it because of that? Should I just remove it?

Is windows defender good security on it's own or do I need more than just that? I've downloaded malwarebytes anti-malware?

Windows 8 Machine - No Display When Turned On

Jan 9, 2013

I've noticed sometimes when I first powerup my windows 8 machine, it turns on, but I get no display on my monitor (has happened with 2 monitors). I am using the latest beta ATI drivers for my card. The weird thing is, pressing delete i dont even get the bios to appear, just a black/dark monitor screen. I am wondering if repairing the bootloader could fix this? How to repair the bootloader? I won't loose any of my data, will I?

After turning off, turning on the computer a few times, I finally get display and can get into windows 8, but it's annoying.

MB is an ASUS P8z68V/gen3

When Turned On Lenovo Y410p - Got A Blue Screen?

Jan 25, 2014

When I turned on my Lenovo y410p today I got a blue screen saying:

Recovery

Your PC needs to be repaired

The Booth Configuration Data file is missing some required information.

File: BCD
Error code: 0x000000d

You'll need to use the recovery tools on your installation media. If you don't have any installation media (like a disc or USB device), contact your system administrator or PC manufacturer.

The only option I have is: Press Esc for UEFI Firmware Settings

I have 64bit Windows 8. I have a Fat32 external hard drive I might be able to use to recover it - but what should I download? Also, can I try to do something in the UEFI settings to fix it?

Sep 15, 2014

I'm using Lenovo Z570 laptop. (Broadcom 802.11n Network Adapter)

Problem:- Can't switch on wifi. The on/off switch is grayed out. While troubleshooting, it says, " wireless capability is turned off".

Solutions Tried:- Re-installed drivers provided by lenovo's website.
Re-installed drivers by windows update.
Reset settings in Bios to default values.
Yes the physical switch is on and the indicator light is glowing.
Fn+ F5 just toggles on/off airplane mode.
Disabled the option so that power management doesn't switches off wifi to save battery.
Other numerous solutions on internet.

The wifi worked flawlessly in windows 7. I even used it as a hotspot (via cmd method).

Maintenance :: System Restore Gets Turned Off Unexpectedly

Oct 25, 2013

Reloaded my computer and downloaded apps...and 2 times I received a different redirect virus and the first thing it does is turn off the system restore and wipe out any restore points. Then, I am screwed...

I always uncheck all the extra stuff like toolbars apps like to get you to download. The last app that did this was the weather channel app.

My question is, how can I configure system restore to require a password to disable it which a virus may not look for? Or anything to keep system restore intact ?

It is too easy for these virus' to keep folks from restoring.

Some Desktop Icons Turned Into A Default Icon

Nov 9, 2013

I got a nasty Malware program "WeCare" from the Imgburn Install (I think) and ran Malwarebytes Anti-Malware to get rid of all the stuff it put in the registry. That seemed to work. I also ran CCleaner a couple of times. Again that seemed to work. However, now SOME of the shortcuts that I created for standalone programs - IBT, HWinfo, Prime95, SSDLife, and RegEdit show as a blank page with the upper right corner folded. I have also run into this issue on a W7 system but managed to force Windows to pick up an Icon from a different source. What file can I delete that would cause Windows to rebuild the Desktop Icons?

I found a .bat file that deletes the Icon Cache and rebuilds it. That solves my immediate issue...but...still curious on who or what caused specific Icons to go to default or whatever.

Turned On Laptop - Cannot See Apps Screen Or Desktop

May 19, 2013

Today when I turned on my laptop the screen was black, not showing a thing. With no options to solve this I rebooted the laptop by pressing the power button for a few seconds.

When I restarted the laptop it started and shown the username/password screen. I input my password and then a pop up window appeared with an error related to explorer.exe

I cannot see the apps screen or the desktop. The desktop is just a black screen with a grey bar. I can access windows explorer by clicking "windows key + E" but I cannot do anything else.

Now every time I start my laptop, the error does not come up, I input my password and I don't see apps screen or desktop.

No Taskbar Nor Metro View When Computer Turned On

Sep 29, 2013

Suddenly i turned on my computer and wrote the password of my user then screen just turned black and nothing came up (not desktop view nor the metro view). Then i moved the mouse and i could see the pointer on the screen so i thought maybe i am on the desktop view (i still guess that's it) but the taskbar from below doesn't show up. I clicked on my keyboard "Windows" button which makes my laptop go to Metro View but it did nothing. All i can do is move the pointer around and use the task manager. Throught the task manager i can open folders, apps etc... but obviously my windows is broken and i dont know how to fix it.

I tried to create a new task (in task manager) "explorer.exe" that did not work.
