Z50 - 70 - black screen start (démarrage écran noir)

Q: Z50 - 70 - black screen start (démarrage écran noir)

Hello,

I have a problem with my LENOVO Z50-70 processor I7.

State before the problem:
There was a system update just before this problem, if I recall correctly,
I used much less my PC than before (unloading the battery often thoroughly ...)

Symptoms during ignition:
- The LEDs mains and batteries are green on the front edge of the PC,
- The SHIFT keys do not light up,
- the screen remains black,
- there is no beep whatever emitted by the PC,
- the screen remains black,
- Hard Disk seems to be turning,
- the fan of the Graphics Card and the Processor turns a little at startup,

I tried :
- Ignition with or without battery,
- The ignition with or without mains connection (connection and disconnection that emit a powerful beep that I did not have before)
- Once the battery is removed, press the start button momentarily, nothing happens,
- Press the NOVO button momentarily, nothing happens,
- Once the battery is removed, press NOVO, nothing happens,
- interchange RAM cards,

I have not tried yet:
- hard drive-free boot and hard drive testing in an external case,

I heard :
- Replacing the motherboard battery?
- Replacing the motherboard?

What might be the other solutions to my problem? I am currently out of warranty.

Thank you in advance for your help.

Bonjour,

Je rencontre un problme avec mon LENOVO Z50-70 processeur I7.

Etat avant le problme :
Il y a eu une mise jour systme juste avant ce problme, si je me souviens bien,
J'utilisait beaucoup moins mon PC qu'avant (dchargement de la batterie souvent fond...)

Symptomes l'allumage :
- Les leds secteur et batteries sont vertes sur la tranche avant du PC,
- Les touches MAJ NUM ne s'allument pas,
- l'cran reste noir,
- il n'y a aucun bip quelquonque emis par le PC,
- l'cran reste noir,
- le Disque Dur semble tourner,
- le ventilateur de la Carte Graphique et du Processeur tourne un peu au dmarrage,

J'ai essay :
- L'allumage avec ou sans batterie,
- L'allumage avec ou hors branchement secteur (branchement et dbranchement qui emettent d'ailleurs un BIP puissant que je n'avais pas avant)
- Une fois la batterie retire, d'appuyer lomgtemps sur le bouton dmarrer, rien ne se passe,
- D'appuyer lomgtemps sur le bouton NOVO, rien ne se passe,
- Une fois la batterie retire, d'appuyer NOVO, rien ne se passe,
- d'interchanger les cartes de RAM,

Je n'ai pas encore essay :
- le dmarrage sans Disque Dur et essai du disque dur dans un boitier externe,

J'ai entendu parler de :
- Remplacement de la pile de la carte mre ?
- Remplacement de la carte mre ?

Quelles pourraient tre les autres solutions mon problme ? Je suis actuellement hors garantie.

Merci d'avance pour votre aide.

Hi,

Can someone please help me? I'm a first-time forum user

I've got an Acer Aspire laptop here that has decided to stop loading/starting up.

When I turn the power button on:
- I can see the Acer logo screen (and also get into setup if I press F2)
- The cursor (_) blinks once or twice
- Then the screen just goes black/blank and stays that way

Twice (when I have left power on at the black screen), I have eventually seen this Windows Boot Manager message (maybe after 5 minutes each time):

Windows failed to start. A recent hardware of software change might be the cause. To fix the problem:

1.Insert your Windows installation disc and restart the computer.
2.Choose your language settings, and then click "Next".
3.Click "Repair your computer."

If you do not have this disc, contact your system administrator or computer manufacturer for assistance.

Status: 0xc000000f

Info: The boot selection failed because a required device is inaccessible.
Unfortunately, I do not have the Windows installation disk.

I have tried using a System Repair Disk (on DVD, burnt from another laptop with same OS)....but got stuck when the broken laptop didn't detect or couldn't read the disk.

I also tried the Alt+F10 system recovery, but after 20 minutes on the "Please wait a moment..." screen, I gave up and turned the power off.

Please help. Thanks.

A:Acer won't start, Black screen / Windows failed to start

Hello noob and welcome to Seven Forums.

Can you get into Safe Mode via the Advanced Boot Options menu? If yes, you can check for damaged or corrupt system files by running a system file checker scan from an elevated command prompt (option two in the SFC tutorial.) If problems are found, run the scan 3 times and reboot the computer after each scan.

Safe Mode

SFC /SCANNOW Command - System File Checker

Another possibility from Safe Mode is to try rolling back your computer to a date/time prior to this problem occuring using a system restore point.

System Restore

A:Blue screen & now won't start in safe mode, screen goes black

I'm writing from my husband's laptop because my desktop is completely dead.

We were out of town for several days and when we returned my desktop was running very slow so I attempted to restart it. It locked up, I pressed/held the power button and when it restarted it attempted to run a disk check. The disk check locked up and I had to press/hold the power button again. When it restarted I got a blue screen ~ stop: C0000218 unknown hard error.

Sometimes when I attempt to restart it I get: checking file system on C:
file system = NTFS

When I attempt to restart it in safe mode, safe mode with networking or starting in last known good configuration I get . . .

multi(0)disk(0)rdisk(0)partition(2)\windows\appPatch\drvmain.sdb
multi(0)disk(0)rdisk(0)partition(2)\windows\system32\drivers\ . . . (various items)

Now it won't start, not even in safe mode. Everything I try ~ I just get a black screen.

** I just tried to restart AGAIN and it ran disk scan, said it had completed disk scan and would restart, the screen went black when it attempted to restart and the screen is still black and it won't restart.

What can I do to get my computer back?

Any help will be greatly appreciated!

A friend of mine asked me to look at his old XP machine because it simply will not fully startup. It does make it through the initial boot routine and the "Windows XP" splash screen appears but, shortly after that, the screen goes black. All you can see is a black screen with a white cursor in the middle of it. The system does not respond to mouse or keyboard input.

I used a Hiren's Boot CD boot disk to look around his system. He has about 40% free space left on the hard drive which seems to function correctly. I am presently running a virus scan (via the Hiren's Boot CD).

I've never seen an XP machine do this so I'm not sure what is going on. I believe he is running SP3 but I'm not certain of this because I can get it fully loaded to check.

Any help would be appreciated.

Background: A week ago on vacation, I opened my HP Pavilion dv7-2173cl (a laptop running Vista Home Premium SP2) and suddenly, green and black lines began forming across its screen. I was later told this was a pressure crack, although that is not what I'm posting about. Freaked out, that day I turned the computer off and on several times using only the power button, once foolishly interrupting a "Startup Repair" process.

Problem: When I got home I hooked up the laptop to my TV so I could see what was going on. After attempting to turn it on many times, I eventually got the BSOD with a STOP:0x0000c1f5 error. I couldn't access the Recovery Module (even to backup) or Safe Mode. Going into personally uncharted territory, I booted from a Linux System Rescue CD to delete the $TxfLog file that was apparently the cause of the problem. I no longer get the BSOD, I get a black screen (KSOD?) (sometimes w/mouse, sometimes w/o) after the "yellow bar" loading screen. I still can't get into Safe Mode but I was able to use a Vista repair CD I downloaded to (finally) backup onto an external hard drive.

What I've Done So Far: I've run chkdsk, checked the memory and hard disk from BIOS options, and run Startup repair. I did the kind of Windows backup where everything goes to one file.

I'd prefer not to start from scratch if I can avoid it. Thanks so much for any and all help guys, I appreciate it a lot.

A:Vista won't start up, black screen before login screen.

I couldn't access the Recovery Module...Do you have a Recovery CD, Windows Vista CD, or Recovery Drive (partition)?What happened when you tried to access it?------------------------------------------------------------You said that you were able to backup onto an external harddrive, so important data is safe.The best option right now would probably be to re-format.

Hey,

This morning my comp downloaded a security update for IE;

Cumulative Security Update for Internet Explorer 8 for Windows XP (KB978207)

Security issues have been identified that could allow an attacker to compromise a system that is running Microsoft Internet Explorer and gain control over it. You can help protect your system by installing this update from Microsoft. After you install this item, you may have to restart your computer.

Since it was installed whenever I turn my PC on it sticks at a black screen for a few mins before re-booting and loading properly.

It says I can remove this update if I want, but I'm not sure I should.

Help please?

A:Black Screen on start up.

mmm, after downloading this update my "each day" account reported that it was corrupt. I went in to my admin account, decided to do an Acronis disk image first and then tried my other account again - this time it worked. Have you tried your admin account, or even safe mode? If so do they load properly. Personally I'm not sure removing the update would be a good idea as it apparently plugs a vast hole in IE.

Hello,

I have a Gateway laptop with Vista. Before today it never really caused me any problems and there was no critical warning signs.

My problem is upon starting my computer the screen is black and nothing happens. I can hear the fan running but at a lower volume then usual. The keyboard does not respond at all so pressing F8 or any other commands is useless. The CDrom does respond if I press eject on the side.
There are two things that I did today that I normally never do. First, I ran a disk clean up and I also had a USB "F Drive" SanDisk inserted into my computer because ironically I was seeing if I could use it to back up all my work and notes but I had no success.

After turning off my computer, this problem occurred maybe 20 mins later after I turned it back on. Also, there is no cursor on the screen it just a blacks screen with nothing else on it so it doesnt even look like that my monitor is on. I tried plugging my laptop into another monitor to see if that was the issue but it wasn't.

If I find a recovery disk to use will I be able to recover my work? Any ideas?

Go with starting up with the recovery disk.

One of my computers crashed yesterday when the circuits blew. It needs to be fixed.

So, I hooked up my other computer, Windows XP Media Center 2005, and upon starting the computer, I see the typical loading screen, but then when my desktop is due to show up, all I see is a tiny strip of my desktop at the top of the screen (or what I assume is such, because the strip is purple like my desktop). The cursor doesn't show up, and pressing Escape, Windows (by the Ctrl button) and the like, doesn't do anything. I even hooked up my other monitor, and the same thing happens.

The Windows XP was working fine in my old residence, if it is of importance. There have been no issues with either computer until the circuits blew yesterday. Everything is tightly connected, and I just can't figure this out with my manuals.

I am using my sister's computer to ask this, so thank you for being patient with my reply. I will be checking in periodically to see if anyone has a good answer. Thank you very much to anyone that can help.

Also, the Windows Xp 2005 was NOT hooked up at the time of circuit blow

Time for some bench testing, look in the hardware section of the forum.
Have you observed anti-static measures? Try disabling some items and boot each time. If you have 2 ram boards, remove one at a time.
If you just moved, reseat everything carefully. Did you jar it or drop it when moving?

My problem is: -I press the power button on my tower; it lights up and the ?hp? logo briefly flashes on the monitor. The monitor goes then blank/black.I press and hold the power button on the tower. The power light goes out, and the monitor THEN indicates ?no signal?, as it should.I repress the power button on the tower, and everything boots up, as it should ? most of the time.Also, I cannot get my tower to wake up from sleep ? I have to force a shutdown, by pressing down and holding the power button on the tower.I am hoping someone out there has a SIMPLE solution. Please note, this is new computer with windows 10 pre installed.

Hi, I hope some of you can be of assistance to me.

This morning when I started my laptop I got the always pleasant black screen treatment...

It is an Asus F7SE, about two years old.

The computer starts, fans are running, lights for power and "on" working, the initial sound/beeps and the "ASUS" letters at the very beginning. Then black screen. I get no BIOS Post (info at the start) and Vista is not starting.

Have anyone experienced something similar or have any idea what I can do?

I have looked around on the net but not found anything helpful so far. I am not what you would call a computer expert but have some knowledge at a beginner/intermediate level.

Any helpful answers are much appreciated.

I have a Dell XPS 8500 Desktop. I have been running Win 10 (With Problems) . I downloaded an update for Kaspersky and needed to reboot. When I tried to reboot it came back to the start page without rebooting. I then shut down. When I restarted I got an error message stating System_Thread_Exception_Not_Handled. It also gave options to troubleshoot the problem. I choose Dell. After going through several steps It Froze. I shut down. I have nothing but a Black screen ever since. Help!

Dell dimension e520

Start it and it goes directly to a black screen.

There are no flash drives or external anythings connected to it.

Next tried tapping F8 for safe mode..the screen comes up and I select safe mode then it goes to the black screen again.

I am running XP and for some reason whenever i reset my computer it continously shows a black screen with nothing but "Enter password" on it. I know the password and once I enter it everything works fine but i was curious how might i get rid of it if its possible.

A:Black Start-up screen

That is probably a BIOS password you have set. Go into BIOS and see if you have set something up by mistake.

Sorry I don't have the specs for this computer as I am offsite but, when we start the computer it won't get to the Windows screen. After the normal initial screen it just goes black with the blinking cursor and never advances further. Weirdly if I opt to boot via the CD drive (even if there is nothing in the CD drive), it will advance and load Windows and function completely normally. The glitch is only apparent when booting up.
 

A:Black screen on start up

Go into the BIOS setup screen and then set the CD drive first in the boot order and then save the change and exit.
See if that helps.

What's the brand name and model name and complete model number of that computer?

I've a Packard Bell desktop PC running Vista Home Premium. Have had it for a couple of years. Have kept up to date with all relevant updates.
On Sunday when I turned on my PC and screen the screen did not display (remained black). Windows loaded and I then turned the screen off and turned it back on again and lo-and-behold the display was OK and remained OK thereafter. The same happened on Monday so I did a system restore to last Friday (when all was working OK). Today (tuesday) the same - black screen on start-up - occured. I had not added any software between Friday and Sunday, I do not use any 'hibernation' type functionality.
If I do a restart the screen displays OK.
Help I'm a bit lost as to what may be causing this behaviour ?
Any advice greatly received
Thanks

I think a good place to start is by doing a clean boot:
