Z77 mpower replaced, black screen after post.

Ok so I've loved my setup for a year solid, until the other day when my Z77 Mpower started smoking from under one of the heatspreaders. I'm all set for an RMA, but in the meantime I had to buy another Mpower board. This is my work PC, and I cannot wait the 2+ weeks for a replacement. So I bought another mobo of the same model and just got done swapping everything out. Now I get post fine, but when loading windows I just get a black screen.
I've:
Updated bios to latest
Taken out all but one stick of RAM
Tried both on-board and discreet GPU
Tried safe mode (stops at "please wait" and doesn't go any further)
Tried startup repair (black screen)
Tried reinstalling windows (freezes after "Windows is loading files..." at the "Starting Windows" screen.
My drives and such all show up fine in bios. No errors on the board. I don't hear the windows chime when trying to boot windows normally.
4 or 8gb ddr3, MSI 670GTX, mushkin 240gb SSD(boot), 640gb WD HD(data)
Please help, as this PC is my Iivelyhood and sanity.
Matt

Update: after clean memtest and trying everything under the sun including a new PSU, I've finally made a discovery. I can finally boot to OS if I enable only 1 core of the procesor. This is under CPU features of the overclock menu.
Now I'll reseat the CPU, check for bent pins, etc. If this changes nothing, do I assume that my CPU is damaged or there's something wrong with the new board? I guess the only way to know for sure is to have another CPU or board, of which I have neither at this time.

Black screen after post

I have a Dell PE 2950 server that was booting fine a few weeks ago. Today I installed it in our rack and plugged in 4 new hard drives (in addition to the two that were in there). System would post but then go black and the LSI raid controller never came up and the system didn't boot into Windows.
So, I powered off the server and removed the extra drives. Powered on and same thing happened.
Next, I tried removing the network cable and the first two drives to try to minimize the configuration. CD/DVD tray was empty, no hard drives, no mouse, one USB keyboard connected (no PS/2 ports available) and a VGA monitor.
Same thing happened, in fact, it started happening even earlier in the boot process. The Dell splash screen and the loading bar show up and the bar doesn't even get halfway done before the screen goes black.
Finally, I tried removing the CMOS battery, waiting for several seconds, and putting it back in, then booting. Same results.
Any idea what could be wrong?

Bhenson1,
Let us try make use of full minimum to POST components with the following requirements just in case there happens to a problem with another component.
System board
Processor (with heat sink) in socket 1
Two sticks of memory in memory slots 1 and 2 ( Try also rotating out different DIMMs)
1 power supply
Control panel (to turn on system)
Side plane
Reseat both PCI risers; PCI-e in center slot, (PCI-e or PCI-X) in left slot. If there are any PCI Cards, then remove all
Remove the CD/DVD tray
Remove power cable to the backplane
Ensure no USB devices are attached.
Let us know if this works for you.

Lenovo G560 - Issue with won't boot and black screen after HDD upgrade

Lenovo G560 - Issue with won't boot and black screen after HDD upgrade.
What happen: My laptop was working fine, no blue screen issue, no funny business at all. I bought a new SSD Intel 120 GB and thought it would be a good idea to replace the HDD. I shutdown and disconnected the power adapter, waited a couple of minutes and removed the battery. I opened up the back case and replaced the HDD. And put all the screws back and put the battery back in.
Problem: The very first time I turned the power on, nothing happens besides a black screen. I pressed the dvd drive it works and opens up and closes. I waited for about 30 mins and still has blac screen. When I mean black screen, no bios menu, no logo, just a black screen with the fan sound on.
I have tried these:
1. Unplugged everything - battery, adapter, and pressed the power on button for about 60 seconds, nothing, the laptop turns on with the LED display on for both on and battery LED's. But nothing but black screen, no sound of windows loading just the fan and black screen.
2. I tried putting back my old 2.5" and nothing but black screen.
Thoughts and suggestions?
Solved!

Black screen after windows auto update

New laptop in use for 3 weeks. After Windows auto update restart I get to splash screen and am able to enter Windows password to log onto desktop. After successfully entering password I am not able to view my desktop; I get the black screen with cursor function; cursor disappears when moved within an inch of left or right of screen (seems to go behind something). I believe I am at the desktop but just not able to view it, because I receive app popups on the black screen (need to update McAfee, etc).
In safe mode I restored to pre auto update date; manually installed all Windows updates; worked fine until NEXT auto update, same problem.
Graphics Card: Stock Intel HD Graphics
Monitor: Generic PnP
Why would it be fine with the manual update and not after auto update?
I do not have an external monitor to attach this laptop for diagnosis. I have run windows partition checks and hard drive partition checks with no issues to resolve.
I did get an error message once when running a diagnosis (can't remember which) : Windows Update Error 0x80070490
No real luck finding anyway for me (the average Joe) to resolve this issue.
If this is a harddrive issue I don't want to keep pussyfooting around while my warranty window shrinks.
I have downloaded driver updates from HP, but cannot get the Synaptics Touchpad driver to download. I don't think this is my issue though.
I am going to manually update all my drivers then manually update Windows. We will see what happens on the next auto update.
Please advise if this is an issue I need to just give up on and return this laptop for replacement. It seems like this is not a completely unheard of issue, but I'm shocked at what we are asked to do to attempt to resolve it. Out of my depth.

Hi @Justanothermom
Welcome to the HP Support Forums!
I understand that you are having troubles with a black screen after an update. I am happy to help you with this.
Firstly, there is nothing wrong with modifiying your update settings. I was going to suggest it myself as I read through your post, and then saw you ask the question. Sometimes updates can have unintended results by the creator. With all the different combinations of hardware, and the fact that updates come from different sources, it is one of those things that is hard to completely control.
Please see the following for how to make adjustments to your update settings.
Turn automatic updating on or off - windows.microsoft.com
Or if you know which update seems to be causing the issue you can take a look at this page:
win 8.1 August 12 updates - black screen after 2nd reboot - answers.microsoft.com

270X Gaming - Black screen after driver install

I just recently purchased an MSI R9 270X Twin Frozr Gaming.
I physically installed the board and booted my PC. Windows started fine, albeit in VGA mode. I then proceeded to install the latest AMD drivers for the card (13.11 Beta). I made it through installation and then rebooted. When I rebooted, I got a blank, black screen after the "Starting Windows" screen. I was unable to boot windows, so I restored to last known configuration and tried again with different drivers (13.9) with the same result.
Does anyone know why windows hangs when it loads the display driver? Any help would be much appreciated.
Thanks

Hi everyone. I just wanted to give you an update. It seems I have resolved the problem.
After attempting other fixes (fresh Windows install, MB BIOS update, etc), flashing the BIOS of the video card fixed the problem. I used the BIOS version
015.040.000.000.002887. I believe the BIOS the card shipped with is 015.039.000.000.002887. Anyway, there are no problems now. I was able to install Catalyst 13.11 Beta 9.5 with no problems and no black screens.
I got the BIOS and ATIWinflash from TechPowerUp. I'd post links, but I am too new to the board.
Thanks guys.

[SOLVED] Black screen after GRUB

Hello everyone
I was setting up a machine with E17 and was trying various DM's since none seemed to work. After attempting to use LightDM, I get a black screen after GRUB. I was trying to read the various logs at /var/log/ but I cannot understand them properly. I tried reinstalling entrance and LightDM with no luck. I even tried editing grub's entry appending '1' or 's' and still no dice. Any help would be appreciated.

Hi tnx for both answers.
I missed something important in Xorg.log. As you can see, fbdev and modesetting aren't loading as usual. I didn't check grub stuff, I don't think it's related, since loading in level 3 (text mode) I get a black screen but I can login as root and turn off the computer blindlessly.

No, I can't get it to work changing DM's. I'm not sure if I pacman -Syu before changing DM's another time. Maybe it wasn't LightDM's fault afterall.

Black Screen after logging in locally to Windows 7 that previously had an open RDP session.

Here is what happens. I leave my home computer on (running Windows 7 Ultimate) and sometimes I will remote to it from another location (work, friends house, or wherever). When I return home, I will go to login, the screen then goes blank (no mouse cursor
or anything). I have to do a cold boot to get back into Windows. This only happens if I ever RDP into it sometimes during the day. It seems random. I've tried logging off the RDP session, just closing it without logging off, nothing seems to be the answer
in that regard. It seems very random at times. I'll go a week and I can come home and it will login fine with no problems. Then the next week it starts giving me the black screen after I come home and login locally. I've seen several black screen issues here,
but usually they are getting it before logon. Anyone have a clue what might be causing this?

[Solved] Amilo XI 2550 - Black screen after fresh install

Dear archlinux users,
I have been reading the archlinux wiki and forums since I started using arch several years ago. It was always possible to solve the problems I ran into by consulting these webpages, therefore a big thanks to the community for the provided help.
Two weeks ago I installed arch on a Fujitsu Siemens Amilo XI 2550. The first problem I ran into was that booting the live-cd resulted in a black screen and I could not even start with installing arch. This problem was solved with the kernel parameter 'nomodeset'.
The first boot of the freshly installed arch also resulted in a black screen after the GRUB menu which was perfectly displayed. After some searching (here and here and ...) I plugged in an external monitor and it showed the login screen. I then installed KDE because I thaught the problem might not show up with X and KDE running. After the login to KDE I realized that the brightness of the laptop display is nearly black but not totally. It seems as if the brightness is at a very low level, but brightness cannot be controlled with the Fn+F8 or Fn+F9 commands. But I see a OSD that indicates that the controls are used but without effect. So at the moment it is only possible to work on the laptop with another display connected to it.
Maybe of use:

and others I just cannot remember.
Masking backlight
systemctl mask systemd-backlight@backlight:acpi_video0.service
systemctl mask systemd-backlight@backlight:radeon_bl0.service
Setting bl_power
echo 1 > /sys/class/backlight/acpi_video0/bl_power
echo 1 > /sys/class/backlight/radeon_bl0/bl_power
Nothing of the above was improving the situation.
Your help on the problem would be highly appreciated.

Hello Trilby,
thanks for the reply.
Trilby wrote:If nomodeset worked with the installation medium, why haven't you tried that for the same problem on your installed system?
The kernel parameter 'nomodeset' results in a working display but without X support, due to the fact that with 'nomodeset' there is no KMS support and therefore no X. But nevertheless I tried it and as expected X did not start.
Trilby wrote:Could you also post information about your graphics card and what drivers you've installed.
The graphics card is a Radeon HD 2700 and according to the above dmesg log it is recognized as RV 630. The radeon module is loaded via /etc/mkinitcpio.conf and xf86-video-ati (1:7.5.0-1) is installed.
I hope the provided information is what you asked for, thanks for your help.

GTX670 - Signal lost/black screen after windows loading icon

Hello,
I hope I am posting this in the correct forum area. If not I do apologize.
Here are my specs:
Board: MSI Z97-G45 Gaming
Bios: ?? whatever pre-installed on mobo
VGA: MSI GTX670 OC
PSU: Corsair HX750 750W
Intel Core i7-4790K
MEM: 12 GB Kingston HyperX DDR3 1600 2x 4GB, 2x 2GB sticks
HDD: SSD Kingston 120 GB (Win7), HDD 1 TB WD 7200 RPM (Win7), HDD 1.5 TB WD 7200 RPM (storage)
COOLER: Corsair Hydro Series H60 Water Cooler
OC: no overclocking done by me..default settings
OS: Windows 7 64bit Professional
So to keep this as direct and as short as humanly possible here is my situation.
Had a gtx670 card that I had to send back to MSI under RMA. They sent me what looks like a new gtx670 card (no dust) that I received yesterday (4 Aug). Last night I removed temporary old card (9800gt) and plugged in new 670gtx. Things seemed to be ok, reinstalled driver after card was recognized. Played one round of Battlefield 4 for testing purposes and all seemed good.
Upon exiting the game things went south in a hurry. Moving the mouse cursor around was extremely slow and choppy. Mouse clicks were not recognized. I could not bring up ctrl-alt-del to get to task manager. At this point the cursor turned to spinning circle as if things were happening. However, after 5+ minutes of nothing changing I did a hard boot.
Restarted and after the windows loading screen the signal appeared to be lost to the monitor and I was left with black screen. This was with the SSD. I then attempted to load into the HDD windows OS that I hadn't logged into yet with this card and was greeted with the same issue.
I can load into Safe Mode with no issues. In safe mode I removed all nvidia drivers and was then able to load into windows normally using basic windows vga drivers. The moment I load the Nvidia drivers and restart the computer I then have the issue again. This happens with both drives.
I have reset the video card in the PCI-Ex16 slot and still received the problem. I have tried a different PCI-Ex16 slot and still had the issue. I put the old 9800gt card back in and windows loaded perfectly and without issues on both drives. I put the 670gt in and try to load into normal windows and I lose signal and get black screen after the windows loading screen.
I'm at a loss at the moment. I think it's the drivers, but could it be the card?
Doing some research I've come across some people saying there may be issues with the nvidia HD audio drivers that are installed with the video drivers. Could it be as simple as uninstalling or unchecking that particular driver?

Flashed the BIOS last night to the latest version and attempted to launch windows with the GTX670 card. I still experienced the same issue where as soon as windows finishes it's loading animation (with Nvidia drivers) and it goes to the login screen, the monitors cut out.
At this point I feel like it has to be the card. The moment I install the video drivers and restart, I have the problem of losing the signal/black screen.
What I have done:
1) Completely wiped any/all video related drivers from the computer and started from scratch. No success.
2) Ran Memtestx86 to see if it's a problem with my memory sticks. No problems found.
3) Put the card in a different PCI-Ex16 slot to see if there was a problem with the slot. No success.
4) Flash updated the BIOS on the motherboard to the latest version. No success.
I have a dual boot computer with Windows 7 64-bit installed on an SSD and a HDD. The problem happens on both drives. Yet, the moment I install my old 9800GT the problem disappears and I can login to Windows just fine.
I will be sending the card back today on another RMA.

Again getting black screen after Exiting Safe Mode in Windows 8 as suggested by hp

I'm again getting black screen after entering safe mode after upgrade to Windows and exiting from safe mode but after exiting my laptop display was of 8.b but after some time it again went back to same black screen problem .I disabled Intel and amd hd 86graphics driver in safe mode.please help .

Hi there ,
Thank you for visiting the HP Support Forums and Welcome! I have looked into the issue you are having with your display Turning Black after entering Safe Mode. I found a document for you called Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot. It would be very helpful for me to know what has been done already so that I can narrow down what troubleshooting would be best for you. You mentioned in your post "again". Is it an intermittent issue? Please follow these provided troubleshooting steps, re-post with the results of the steps in the document, and any other troubleshooting steps you had tried and the results. Have a great day!

Black screen after BIOS update

Hi there,
After updating BIOS with regular HP software (i forgot the name now), the computer shut down and from that moment when i turn it on the screen stays black (with computer apparently running). I read so many posts with similar problems and i tried few things but without success. I know that i am very close to solve the problem but from all the suggestions i am now simply confused. I would like to ask, if someone can guide me through step-by-step procedure, i figured out that i need to install a BIOS version on USB-stick, but exact details i am obviously missing.
I have HP Pavilion dv 6700 Entertainment PC and new HDD inside without HP_TOOLS on it.
Thank you veeeeeryyyy much!

Black screen after windows logo problem

Hi people, i have the HP Probook 4530s LH306EA and i have been using it for 3 years without any problems but this week after i did a restart on my laptop i got a black screen after the windows logo.
The problem is whenever i install the AMD Display driver it says that there were some errors during the install and the pc freezes and restarts into a black screen...

Windows 8.1 64bit
Is there any solution to this or some other drivers?

you wouldn't by chance be attempting to use a Sandforce controller using SSD?
please list your components >>Posting Guide<<!

[Solved]Black screen after "waiting for udev uevents to be processed"

Hello friends,
Starting from late Dec., my laptop goes black screen after "waiting for udev uevents to be processed", after updating kernel to 2.26.32.*. The strange thing is that even the screen is black, the keyboard is working. For example, I can turn on/off the status lights of capslock and others. I guess something might be wrong with udev uevents configuration with regard to the latest kernel. I've noticed that in the new kernel, there are two drivers for intel integrated graphics. My laptop has a 855G, which is supposed to be functional by both drivers, at least according to the kernel description. Maybe because the udev is configured to use the second driver (for newer graphic chips), rather than the first driver, which caused the problem?
Regards,
Wen

Black Screen After Windows 8 64-bit Upgrade (Clean Install) on TouchSmart IQ508A (IQ500 series)

Hi there,
Just installed Windows 8 and am getting a black screen after booting up like many others. I currently have disabled the graphics driver and this has solved the black screen issue but I can no longer use my web cam for Skype (although web cam works for W8 Camera App oddly).
To date I have tried the following:
Loading up the latest Nvidia drivers from the Nvidia website
Attempting to use the drivers for Windows 7 both in compatability mode and normally. I unzipped SP44488 to get this working
I know many others are having this problem so I really would like someone from HP to respond and state whether a Windows 8 display driver for the Nvidia GE Force 9300M GS is being developed.
I ran the compatability wizard prior to the clean install and it came up with no issues so I am very disappointed I am having these problems.
I've found out that HP have a customised version of the above card so that explains why the Nvidia drivers dont work so I believe HP is therefore obligated to provide a driver.
If anyone else is having similar issues please respond as this will hopefully lead to more action.
cheers
Steve

I'm in the same boat. On my IQ804, the Nvidia GE Force 9300M GS card crashes when I use NVidia's latest Windows 8 driver and Microsoft's LIVE UPDATE drivers. I have to resort to the Standard VGA driver in order for the pc not to crash into a black screen.
I read on another forum you can try installing a July 2012 version of the driver from NVidia and that should solve the problem. I tried it once. Using the July 2012 version, the screen would stay on longer, but eventually it crashes into a black screen...but definitely more usable than the latest from NVidia and Microsoft.
I too have heard that HP used a customized version of the graphics card and that's why neither HP nor NVidia's drivers work.
I also tried installing the Nvidia GE Force 9300M GS drivers for Windows 7 that I downloaded from the HP website. It didn't work either. It actually failed to install altogether, saying my system is incompatible.
As is, the pc works fine. But videos and games that require motion is noticably choppy.
Any help from HP??

Black screen after login while on battery with graphics switching enabled

Getting a black screen after entering my password while logging into my account while on battery with graphics switching enabled. Everything is up and running, I just can't see it.
I can log into the guest account on battery
I can log into my account while plugged into power
I can log into my account on battery if graphics switching is disabled
I believe something that is starting up in my account is causing the system to switch from integrated to discrete graphics on login, and that switch isn't working correctly on battery power.
As a work around for now, I can run with graphics switching disabled, but I'd like to solve this so I get longer battery life.

I had the same issue and managed to reslove it.
Shut down your machine.
Power it back on while holding the 'shift' key (left or right, doesn't matter)
You will see a greay progress bar go across the screen while you boot in to 'safe boot'
Once booted, login, and go to Energy Saver and turn on 'Automatic Graphics Switching'.
Reboot back in to normal mode, and you should be able to log back in and see again.
I did this without being plugged into AC power.
Hope it helps!
Cheers!
