Dell M5510 - Unable to boot - display works, no bios or boot screen

Q: Dell M5510 - Unable to boot - display works, no bios or boot screen

This morning I went to use my laptop and it is no longer booting. The power will come on and the power button lights up, the keyboard lights up. If I let it sit it will stop running after around 30 seconds to 1 minute.
If I click the power button after it started, I can hear the fans spin up then the system shut down. I have ran the LCD test and it works. Their is no boot screen at all or dell screen.
I updated the bios last week and I had run it since. I also took the whole thing apart today to remove the bios battery for 1 minute and put it back together but it still does not run.
Is their a way to diagnose motherboard issues? why would it not boot or is their more steps to look at?Thank you

Preferred Solution: Dell M5510 - Unable to boot - display works, no bios or boot screen

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


I am having problems with direct booting into Windows 8 installed into a VHDX file.
This is a four-partition UEFI boot on a GPT drive. EFI files are residing on a second partition of disk 0 (the ESP partition) in the EFI folder. The boot virtual disk is residing on the fourth partition of that disk 0.
When I turn on the PC, it shows black screen after the BIOS POST screen. No Windows 8 boot menu, no other information is displayed. However, if I press Shift+F12 (or F12) to start Dell BIOS Boot Menu and choose Windows Boot Manager from the UEFI part of
the boot menu, Windows 8 starts to boot without difficulties.
How do I make Windows to boot automatically without having to select Windows Boot Manager in DELL BIOS boot menu?
I believe I messed up with boot sector somehow... What needs to be fixed provided that Windows 8 will boot into VHDX file?
Thank you.

Well this is the world we live in And these are the hands we're given...

I have an XPS 8700 desktop all stock bought a little over a year ago. Last night I turned it off when I went to bed. Today I turned it on and it will not go past the first dell loading screen. It freezes and I'm unable to press any buttons (F2, F12 etc) I put it a different hard drive to see if that was the problem but it still continued. HELP PLEASE??

A:Dell XPS 8700 Desktop, Freezes at dell loading screen unable to boot up.

Hi Mattmazz
Thanks for writing to us. 
Please disconnect all the connectors and then hold down the power button for 15 secs, now remove the memory modules and put them back one by one and observe for any changes. 
If possible please try another set of memory modules. If there is a separate graphics card, remove that as well and try the onboard.

I have issues booting my desktop. It shows the initial Intel chipset screen (F10 for BIOS, F2 for boot order) and then screen turns black for 2 seconds and computer reboots back to the Intel screen.

Configuration of my PC:
intel core [email protected] GHz.
DIMM (4 slots) with 4 GB memory each - total 16 GB
OS: Windows 7 professional
Graphics Card: GTX 560 Ti

Steps Performed so far:
1. I can go into BIOS but cannot boot the PC.
2. I tried reseating all memory modules and used 1 memory stick one at a time. No success. 3. Removed graphics card and connected monitor to integrated video port on mobo - no success. 4. reseated HDD connections - no success. HDD, 5. RAM are getting detected in BIOS.
6. Unable to boot to safe mode.
7. Tried reinstalling the OS using CD. Stuck at Windows is loading file. The bar moves for 5 seconds and then stops.
None of the above worked

Before this happened, my PC got BSoD and was giving memory dumps. I did a Hard Boot and now its not coming up.

Hi everyone:

I have a Dell Inspiron 1720 with Vista. Days ago I remember downloading something that made my laptop reboot. Upon rebooting, I still can't get past the bios screen. (Actually I do, but only to a black screen with a blinking cursor.) I've pressed F12 to change the boot order to CD Drive. Ive inserted a vista bootable disk in and heard it spinning and working. Seconds later, I get an error along the lines of, "Not a bootable disk, press X to retry". I've tried the test that is available in the F12 setup, but no errors were detected.

Any help would be greatly appreciated.

Thanks, Dala

Got my Precision m5510 last week. Was on bios 1.2.0. Screen was flawless, and premiercolor is amazing.
Yesterday I upgraded to the new 1.2.10 bios. Amazingly, after I installed this new bios, I started getting intermittent screen flickering on lower brightness settings. It wasn't a pulsing or regular flickering. It was instead like seeing micro flashes to a higher or lower brightness. Couldn't find a regular pattern in the flickering, completely random.
Most visible on lower brightnesses, but I even noticed it flickering a little on the higher brightnesses too.
I downgraded my bios back to 1.2.0, and the issue has gone away!!! I'm pretty sure there's something wrong with the 1.2.10 bios. It says its supposed to fix screen flickering (and Issue I never had in the first place), but instead, the new bios gave my computer flickering issues.
I currently have a Service Request in with Dell about the issue, but I wanted to see if other are reporting similar issues.

Hi everyone,
I have a Dell XPS 17 L702x that I was prepping to sell.  The basic specs are:
Intel i7-2760QM
16GB of RAM (4GB x4)
NVIDIA GeForce GT 555M with 1080p 3D screen
500GB 7200 RPM HDD x2
Windows 10 Pro
Like I said, I was prepping to sell the laptop.  The laptop was functioning properly.  I had wiped the HDDs clean and was in the middle of performing a clean install of Windows 10 pro from a USB drive.  I have done this before and never had a problem.  The install started correctly. I selected the drive that I wanted, and the installer wrote the files to the drive.  The laptop then restarted.  The power came back on, the fan started up, and I could hear the optical drive and HDDs spin up.  However, the screen stayed blank/black, and the Dell splash screen never appeared.  The activity light on the USB drive never comes on.  The normal functions keys do nothing.
Here are some troubleshooting things that I have tried:
I removed the RAM and HDDs.  I get the typical 2 beeps from not having any RAM.  Motherboard seem ok.
I have tested the RAM in my work Latitude E6430.  The E6430 will boot with the RAM from the L702x.  The RAM seems ok.
I have tested each stick of RAM one at a time in various slots in the L702x.  Same problem, blank screen, and no beeps.
I have connected the HDDs to the E6430 with a SATA to USB cable.  I can format and read/write from/to the HDDs.  The HDDs seem ok.

I have had several Dell Laptops (D630, D830, E6410, E6510, Precision M4500), and with the D630 and E6410 Dell was VERY helpful after the warranty expired (in one case by 5 months).. even replaced a system board or 2 since tons of people were reporting issues similar to mine on the D and E series.

on my Precision M4500, I called Dell 1 day (24 hours) after the warranty expired.

Issue: The system would REFUSE to boot past the dell BIOS splash screen.
It would finally boot after 10 or so power cycle attempts.

Dell refused to "help" me but did give me some advice
now ... 1 month after the warranty expired - the issue is back

System Info:
Dell M4500
16GB DDR3 RAM (Dell Certified) - issue remains when I use the 8gb in my e6410
bluray drive (I also tried to boot using the dvd drive in my e6410, issue remains)
intel 6250 wifi/wimax card
gobi 2000 card
i7 cpu
NVidia FX 880 gpu
bios level a15
os: dual boot via GRUB - Ubuntu 13.10 and windows 7 ultimate (both 64 bit)

when it does finally boot, I get a message about intel management engine booting the factory image or something to that effect

it will NEVER boot past the bios splash screen on battery only (even with a new battery)
once booted, I can unplug and get about 2 1/2 hours of usage from the pc

I can access the bios settings with no issues - even on the "no-boot" power ups

once it does boot, there are no other issues

after reading on the internet I found this to be a COMMON problem

I have an HP Pavilion dv6000 (Vista 32bit Home Edition) that has suddenly stopped fully booting. When the power button is pressed, the appropriate keyboard/disk lights come on and the fan starts. A black screen appears and then 5-7 seconds later it shuts down and restarts. There is NO mouse cursor or blinking line in the top-left corner as some of the other forums have described - just completely black and the computer continuously restarts.

I am unable to access the BIOS or any other system options at the startup. F10, F8, F2, the ESC key, etc all do NOT work. Although, the interesting thing is that F10 and the ESC keys are the only ones that allow the computer to stay running for longer than 5-7 seconds. When these keys are pressed at the startup, the empty black screen stays "lit" and the computer stays on (no restart). The fan increases in speed (high) after a few minutes, slows down again, and this process is repeated. A hard/forced shutdown is needed to turn the computer off.

I cannot change the boot order since I'm unable to access the BIOS. Thus, my recovery disks won't work. I feel completely stuck here. ANY help or advise is greatly appreciated - particularly concerning a way to change the boot order in this situation.

A:Vista fails to fully boot, restarts, black screen, unable to access bios

The fact that the F10 and ESC keys leave it going for a bit extra tells me this is fixable.
The F10 button allows you to enter the setup facility.
The ESC button is used to change the boot order.
There is also an F12 option for your laptop.

I have located the service manual, have a look at 2.3 Troubleshooting flowcharts.
If you require any more help let us know.

I have a Dell M5510. I previously had an issue withe battery swelling up which then caused a MB failure. I have since had dell replace the motherboard. This worked fine for around 2 months but recently I started to have an issue. If I left my computer over night when I came to use it the next day I noticed it was restarted.After further using the computer I found out that it would start to get black squares on the screen and then freeze. It can even do this on initial boot when it first enters windows. I have also got these black squares on the login page for windows. The squares are repetitive almost in a diagonal across the screen. I will capture a screenshot next time it happens.Once the black squares happen I have about 0-30 seconds before the whole system will freeze. I wanted to know if anyone can recommend a solution for this or tell me where the problem relies?I have tried to roll back drivers for the video card and various other items as well.Thank you

So i was playing Doom 3 and the game crashed so badly that i had to restart my computer (im running Vista 64bit by the way) and upon restarting it, it gets to the BIOS screen but after that it just goes black and nothing happens, i have tried the F8 thing but all that brings me to is this boot menu, but not advanced boot options, i have also tried pressing F8 or F5 after i selected hard disk from that boot menu, still nothing happens. So i cant access "restore to last good system configuration" because F8 doesnt take me to the right menu to do so. Also i dont have a vista install disk so am i SOL and have to just get another disk or upgrade to windows 7? or is there some other way to do this? Any help is appreciated!

Sorry first time poster. I wasn't too sure whether to post to the Windows forums or hardware forums. From what I can see, this seems like a hardware issue of some sort.

The problem I have is that during bootup my PC goes through all the normal things. It detects my CPU, detects RAM etc. gives me nice BIOS Post messages that appear normal and then goes to a black screen. It will then sit there for 50 seconds (i've timed this twice) and then proceed to go to the windows XP startup screen (which takes about another 10-20 seconds to load up windows).

I've attempted to log the bootups by using the Windows Boot logger (by pressing F8 before windows boots). The ntbtlog.txt file isn't very descriptive, and only lists that a whole lot of drivers have been loaded, and some that haven't (it doesn't list any errors).

I've also tried using BootVis to analyse the bootup. I found this a little hard to decode the information it gave me, but there doesn't seem to be anything untoward happening.
The last boot logger I tried was bootLog XP (by greatis software). According to bootlog XP, windows is only taking 19 seconds to load up.

Can anyone suggest any other ways to analyse the boot sequence and discover where my computer is stalling?

(specs are below.)

Thanks in advance,


CPU: AMD Sempron 3000+ Socket 754 (unsure whether it is Paris or Palermo core)
MBoard: Foxconn NF4K8AB-RS

Hey guys,

I've been searching the web for solutions for hours now and won't find anything that works for me. You are kinda like my last hope.

I have a Asus A54C Laptop here (it's my brother's), that won't boot. If I turn it on, it quickly shows the Logo screen and nothing else happens.
If I have a WIN7-DVD in the DVD-drive (created with downloaded ISO, it seems to be working on another laptop), the drive makes some noises but nothing else happens.
If I have a Ubuntu-Live-USB plugged in (worked on this Laptop before), nothing happens.
If I press F2 repeatedly after turning the Laotop on (it's the BIOS-key), nothing happens.

What I've tried
I tried several potential BIOS-keys, although I am 99% sure that F2 is the one.
I tried the turn off, deplug battery and cable, hit power-switch 20 times and for a minute thing.
I tried unplugging the Laptop while it was in the logo screen, hoping this would bring me to BIOS after starting it again.

How I got there
An Ubuntu system has been installed on the Laptop for a while. Now, my brother needed a windows and I wanted to create a dual boot system (what I had succesfully done before).
Some stupid mistakes later, I had a corrupted Win7 and wanted to overwrite it with a fresh install.
I tried to delete the 100MB system reserved partition (in the WIN7-installation menu) because I thought, a fresh install would create a new one. This took about 1 hour (for the 100 MBs) without any visible progress, I finally ... Read more

A:Laptop won't boot (Logo screen),can't boot from USB/DVD or access BIOS

Hello and welcome Joe mate the BIOS key is F2 and this is the manual for that model sorry but I can only access the English version - if you type in what you want to search for it automatically will go to that setting or instruction. https://www.manualowl.com/m/Asus/A54...261331?page=84

Now if you select the optical as the first boot device and it will not go then maybe it needs a new optical drive - very cheap these days and you may be lucky that it is held in with one screw on the underside of the laptop without any pics it is hard to tell - it possibly could be in that manual.

Now for the BSOD's please use these if you want to get them analysed

Hi, I have an unusual problem with a Dell Desktop. At the location where the computer is assigned (it's a work computer) the computer will not boot past the first Dell boot screen. it is on the screen where it says to Hit F2 for setup, F12 for boot options..etc.. There is a bar that fills up while booting, well this bar never fully fills up it just freezes on this screen.

If I take the computer to my location the computer boots and runs just fine. I know this other location has had power issues in the past and am thinking it is an issue with the power at the location but none of the other computers at the location are doing this. I have tried several other outlets at the location and same thing happens. Any ideas or has anybody seen anything like this before? thanks..

Prior to this, I was gaming and my screen froze with many blue and white vertical lines across. I held down the power button to restart, but it only loads till the Dell logo with the dots circling then the screen will flicker with some random lines across (see attached image) and then it goes completely black after.

I tried many times to start and in 1 out of 5 tries, sometimes the Dell logo appears with "Please Wait" at the bottom and there are options to Troubleshoot, I am able to enter the Safe Mode with Networking. 
I tried doing a system recovery to an earlier date in Safe Mode and it ran till the part when it had to restart with the Dell logo, the same screen with lines appear again or sometimes just a black screen after the logo.

Hi Folks

I am having trouble with a new computer:

Processor dual core Intel Pentium 4 3.0 GHz
kernel is
AMIBIOS ACPI BIOS Rev 0206 (American Megatrends)
BIOS Setup Utility v. 02.53 (American Megatrends)

I am unable to enter the American Megatrends BIOS Setup Utility menu. As soon as the POST menu appears I hit the Delete key, and when the Setup Utility menu appears the PS-2 keyboard (IBM KB-7953) is locked (with num-lock on) and no keys work. No beeps, no error messages, no nothing. Unplugging the keyboard and plugging it back in does not help. I reset the computer and if I let the POST finish and the computer boots, the keyboard and mouse work fine.

When the Setup menu comes up, the cursor is at Main, and the System Time, and hours are selected. As I mentioned above the keyboard is frozen and I can't navigate around or exit with the escape key.

I tried entering the Setup Utility with another keyboard (USB) and got the same result.

Any suggestions appreciated.


A:Keyboard freezes at BIOS Setup menu, but works when boot finishes

Well... you might wanna know that American Megatrends use the "F2" key, not the "Delete" key to go into the setup.

I have an Asus L2000B Laptop, and one day a friend was using it and found unconfortable to use the touchpad, and asked me if he could use one of the mice os another computer in the room, i said sure, why not?

Well, it was a ps2 mouse and he hot-pluged it!!! :S

Result: the laptopīs keyboard stoped working and so did that ps2 port and also the sole serial port , but not the touchpad.

Restarting, cleaning the plug and all that did not work.

Now when I boot, i get a 'no keybord present/keyboard error' at startup, however, it works fine in the BIOS and in DOS!?!

When Windows boots it lights Num Lock, Caps Lock, Scroll Lock an the keyboard no longer works

In Linux, No lights go on, but it doesn't wor either.

I'm certain that there is damage to the Serial ports/ PS2 ports chip but it's not all busted and probably just ignores any command and just gives outputs.

Now, I've been using a USB keyboard to 'make do' but its very annoying an not very portable.

Replacing the MoBo is out of the question as it costs more than the PC is worth.

I seek a way around the windows drivers, a simpler less demanding driver!

As you know, when the notebook is on AC power, the display uses maximum brightness. When it is on batteries, it uses a reduced brightness.

The problem that I observed is that If I start the laptop on batteries and plug in the AC Adapter while BIOS is loading, it does not change the brightness to maximum. Why ?

If I plug it in after the BIOS screen, it changes the brightness perfectly.

Please advice on how to correct this...

"Cannot Display This Video Mode " is not an uncomon error. However due to additional problem, the regualar fixing method will not be sufficent.

My graphics card "Nividia 8800 GT" was buged simply due to to software gliches. And so I reinstalled the driver to restore it. After that, I had to restart the computer as usual.

This is where the problem started to happen. When restarting windows, the proggress bar is shown as usual. But when it gets to the login the screen goes blank, and the message "Cannot Display This Video Mode" is displayed.

The usual repare is to boot up in "Safe mode" and change the display settings. Unfortunatly, I can not. When booting the computer in that mode, loading stops. I belive this may be caused from a missing windows file, but cant be certain.

I dont have another computer to conect my hard drive to so I cant access any files in it. How can I get around this? My only option I can see is is to change somthing in the BIOS. But having went through it already... I dont see what can be done with it.

I have a Packard Bell PC running AMI BIOS which won't boot from the HDD but displays no error. It will boot from CD fine. I've run FIXBOOT, FIXMBR and CHKDSK from recovery console, without success. Maxtor disk utility reports no problem with HDD. Probably Windows reinstall needed.

My question is how to display the POST text. During POST it just displays a "Packard Bell" splash screen. I want to see the details. Usually there is a BIOS setup option to display boot text rather than the splash screen, but I can't find one.

The BIOS version is 8IDMNF V1.0M

Thanks Phil.

I have two Dell XPS 9343. I also have two Dell MST Monitors, and for my other laptop, an MST Splitter hooked up to two monitors. Both BIOSes are running the latest BIOS firmware.

In both setups, if I turn my computer off and perform a cold boot with both the Power Supply and the MST displays plugged in, the machine doesn't boot, but instead sounds some sort of BIOS alarm (loud buzzing sound, short pause, loud buzzing sound, short pause) until I turn it off again.

In the case of this alarm sounding, I also noticed that the battery light flashes orange and white very rapidly.

In the case that this happens, turning off and turning on again after removing the power or the Displayport cable connected to the MST devices causes the laptop to boot correctly. I then plug the removed cable back in after it has passed the DELL screen.
What is it? How can I fix it?

After about 2hrs of searching, I was unable to find a post the worked for my particular problem.

Earlier I was trying to fix a DCP latency issue and latencymon suggested I update my BIOS. I got the BIOS from Asrock directly. During the update I was given a BSoD and memory dump. The dump froze at 15 and I eventually turned off the computer. Upon rebooting I was unable to get a display.

So far I have reset the cmos, switched between gpu and integrated graphics, removed the gpu and other adaptors, let the computer stay off for 30min; all of which has not worked. When resting the cmos I used both the jumper switch, quick clear, and battery removal.

My power supply blew up a few weeks ago, finally got round to ordering a new PSU, it worked briefly but couldn't power my CPU fan enough so PC kept cutting off. So I returned that and got my new PSU today.

Plugged it all in and everything lights up in the right places and appears to kick in but I get no display, no beeps, no bios.

I took the hard drive out and put it into a caddy and works fine, can browse the operating system files okay. Not sure what else to try and test, don't have spare motherboard/graphics card/CPU to try them.

Graphics card fan is powered up and spinning away fine.

Am getting absolutely no beeps whatsoever when the pc is turned on.

Any suggestions would be great, am losing the will to live with it now...

A:Solved: PC Won't Boot Up. No Beeps No Display No Bios

Read other 6 answers


I plan to have two installations of windows 7, on each harddrive. I don't want a dual boot setup in the traditional sense, where Windows adds it to startup options, and the boot files are all placed on one drive, if that makes sense.

What I am after are two totally independant systems that are not aware of each other, by installing one first, then unplugging that drive, then installing the other.

The only way to boot these is via F12 boot menu, where you would select to boot from a drive, usb, or cd.

My question is, would it be possible to set in BIOS options, to always display this F12 boot menu on startup, rather than having to quickly time hitting the F12 key?

I guess this is dependant on the motherboard bios itself (Gigabyte Z87) but I have no idea what this option would be called or if it exists.

Any help would be appreciated.


A:How to display Bios boot menu on startup?

Not possible as far as I know. I have not seen any option in the BIOS to do that. The best you can do is set the drive with the OS you use most often as the first boot device. Then use F12 to switch to the other drive when need be.

Hi all
First time I've posted here. Nice to meet ya'll. Thanks in advance for any help you may be able to provide.

I'm having an issue with my Compaq 5108US (AMD 1.3 Ghz, 80 GB, 512 MB RAM) not booting up properly. Once powering up, nothing displays on the monitor. At first, I thought that it was my video card (ATI Radeon 9600). But given that the card is relatively new (1 1/2 yr old or so) it didn't seem like the issue. I tested a few things but to no avail. Still nothing on the monitor.

I also thought that it may be the monitor, but hooked it up to my laptop and no issues at all. Monitor works fine. I've also tried to hit F10 to get into the BIOS setup and also tried to boot from a recovery CD, but nothing works.

After trying a few other things that didn't work, I took a step back and tried to think of what else might be causing the problem. I rebooted once more and noticed that the lights on the keyboard don't ever flash and listening to the computer it doesn't seem like it's fully booting up. Given that the keyboard lights don't flash it seems like it's not booting properly through the BIOS.

At this point, I'm stuck. I have no idea what's wrong or how to fix it. I've had nothing but problems with this poor computer and am about two steps away from junking it, stripping it of any salvagable parts and buying something new. However, I can't understand why it just died on me. It was working... Read more

A:Boot Up Problem -- No Display -- Possible Bios Issue

Hello Atbennet

I would disconnect all drives and see, if you can get post ( power on self test ) if you are not able to get that then it's pretty hard to go any further.

Check your cables make sure they are attached firmly and no pins are broken or bent.

When was the last time you checked the power supply unit and I have heard of video cards failing in 6 months.

You could try unpluging everything from the board, except / cpu, ram / keyboard/ to see if this works. Then you can add devices one by one. Theirs a good chance your pc hangs up after a certain point after bootup, which could be caused by your hard disk drive.

Hope this helps.

For the last few days I have been trying to access into BIOS or Display Boot Options with tapping the keys with " DEL " for BIOS and " F12 " for Display Boot Options. Even pressing down both keys at a time on my keyboard and go through in normal boot with Windows 10 logo screen then type in password. I am sure that you know this desktop is not supported UEFI settings. I did try with Settings\Update and Security \ Advanced Options \ then have 6 names on the double column but I am not sure which one to pick to fix the problem. Here are the 6 names below: System RestoreSystem Image RecoveryStartup RepairCommand PromptStartup SettingsGo back to the previous build All I wan tis to fix two things with pressing the ekys for BIOS and Display Boot Options.

In order to boot from a CD (which I know works in other PCs), I tried the following changes in the BIOS (v. 1.26 N1XET48W, 2017-12-12, ME firmware v. on my new Thinkpad L570:  Restart-menu ? ? - OS Optimized Defaults? ? DisableStartup-menu ? UEFI/Legacy ? ?Legacy only?Security-menu ? Secure Boot ? Secure Boot ? Disable I found those recommendations here on the Lenovo website.  The result was that I got a boot-menu, but NON of the items on the menu could actually boot the laptop... So I had to change everything back again in the BIOS to be able to boot at all...!  My L570 User Guide mentions using a program called "Thinkpad Setup" to configure booting, but there is no such program on my L570! I tried running "Lenovo Settings" and Lenovo Vantage", but it didn't contain anything relevant. This is NOT satisfactory!

I'm not able to use an external display during the boot process + Bitlocker Screen. T480s on a USB-C 40AF Dock. This functionality exists with T470s and the 40A2 Ultra Dock. There is the proper Display On Dock BIOS setting avaible. This funcitionality exists with the P52s and the USB-C 40AC Dock. It seems like the T480s is missing this functionality, and I want to know if there is a planned BIOS update to fix this issue. I've tried every other possible BIOS configuration, and both USB-C ports on the T480s, there is no way to get an external montior to display during boot when that external display is plugged into a USB-C dock. Please let me know. Thanks!

I have a new Dell XPS 15 9550, which I recently did a clean install of Windows 10 64 bit on.  The laptop has two display adapters:- Intel HD Graphics 530- NVIDIA GeForce GTX 960M
I've been struggling with a black screen issue for several days.   When I boot up the laptop, if I hurry I can get past the Windows login screen.  Within 15 seconds after that, the screen goes black, and it appears that the computer is hung.  The keyboard keys still light up if I push them, but there is no mouse.  Plugging in an external monitor doesn't help.  Control + Alt + Delete does nothing.  I am forced to hold the power button to shut down the computer.
Using safe mode, I am able to disable either of the two display adapters.  Then I don't have the black screen problem.  I have also discovered that I can leave both display adapters enabled if I leave a DA200 USB-C adapter plugged in to the laptop (with nothing plugged into it).  If I unplug the DA200, the black screen comes within seconds.  This is the opposite of what I would expect if there was a problem with the DA200.
I have installed all of the latest drivers from Dell's website - some of them multiple times.
Does anyone have any suggestions?  I am getting quite frustrated...
Thank you.

I clicked on the top 1 (which is to perofrm a new instalation, as i read there will be an option to repair rather than format). However, there is a problem, the box on the screen which shows your partitions says that it cannot access the media I have never ever seen this before!!! what can i do!! its as if it wont even detect my HDD which has my XP installation on it. Will i have to use the repair control panel? if so can someone help?, ive never used it.

Hi and Welcome,
Normally if the hard drive goes out you don't get past POST. I know that you say it won't boot up, but try going into safemode. After rebooting keep hitting F8 until you get the screen that says safemode, safemode with command prompt, etc.

Having an issue with all Dell 7510's and associated docks we've deployed to new users at my employer. The external keyboard won't work at the Bitlocker prompt. These PC's are imaged for Win10.
I've sifted through the BIOS settings and have had no luck getting it to work. One thread I found said to make sure the Post Behavior -> Fast Boot setting is set to Thorough. Verified that is the case.
Note: if I undock and dock the PC the external keyboard will work that 1st time at the bitlocker prompt, but at next reboot it doesn't work.

Mother Board: Gigabyte 3.2GHZ
OS: Windows 8.1
Problem: When the computer is powered on it boots normally. However, all function keys or cmd keys to get into BIOS (F2), BOOT Menu (F8), Set up menu (F12) are disabled.
Possible Cause: Ransomware, I know for a fact my son installed a .exe file that put ransomware on his computer due to the HDD being locked and inaccessible. Also, when logging into his user he is prompted with the ransom log on by GoTLINKS.
Attempted Fixes: I've tried removing the HDD cables and booting in hopes of getting forced into the boot menu. However, no drives are detected and I am prompted to insert the OS Disk and hitting ENTER. Upon doing so all KBoard keys are disabled and computer must be restarted. At this point the computer will boot from the OS Disk and allow for a install of windows or windows repair. Upon trying to reinstall the OS (after plugging the HDD back in) the OS Key states it is not retrievable, even though it is on the tower of his desktop. This happens after the key is inserted. (The key has been registered prior to this all happening). When going into windows repair from the disk I am given 3 options. System Refresh, System Reset, and Advanced Options.
System Refresh: Error: A Valid OS must be selected. Please select a valid OS and restart your system. 
System Reset: Error: The disk drive is locked. Please unlock the disk drive in order to proceed.
Advanced Options: CMD pro... Read more

Hi all

I am having a weird issue, as the title says, I am unable to boot into BIOS when I have the external HDD connected via USB 3.0.

when i want to start it up and boot into windows it starts to load the windows installer which you would find like on a win 7 install disk but then stops.

- the external HDD is not loaded with any win 7 and is not setup as a bootable image, its just data
- the HDD is a Buffalo Drive Station 3 TB with USB 3.0

my current setup looks like this below, i suspect that something went wrong during the OS install despite not using this HDD for any installation but another USB dongle which was slip-streamed with the USB and Samsung nvme drivers necessary for install.

On my asus laptop i did not have this issue before just with this new built i just did.

i have to unplug the HDD so i can boot into bios and windows normally.

i cant see the boot order in BIOS as the drive is not live and visible even if i connect it in bios once unplugged previously.

any help appreciated or if more info is needed, thanks much
