GX Won't boot, no display.

We left the house during 4th of July weekend. When we got back, my GX has stopped working. When I turn it on, the HD light turns on, and stays on, but I can't hear it wind up at all. The display shows nothing, not even a flicker of life. The cooling fan does come on, though. The touch panel lights and LEDS all come on, but it isn't even trying to boot. Can someone walk me through some troubleshooting so I can at least diagnose this?

Well, I removed the HDD, the GPU and all but one stick of RAM, and still nothing. Something must of fried, but I'd like to know what so I can replace it. Unit is not under warranty. I would try yanking out the CMOS battery, but I can't find the dang thing, perhaps the battery is dead, but that shouldn't prevent it from even getting to the POST screen would it? I have a hunch it may be the CPU, it was a little dark underneath the heat sink, where what was left of the cooling paste was, just wish I knew for sure before I go start buying random computer parts I may not need. Any thoughts?

Won't boot - no display, solid white light. Fans spin up and gets loud.

Hi Everyone,
I have a Core Duo 20" that won't boot. The display won't light up, and the white light stays on the whole time. No chime. Fans start slow, but then gradually gets very loud after over the course of a few seconds.
I've began taking it apart. One suspect area is the DC/DC Inverter board. The POWER_GOOD line is only showing 0.16V. Most power supplies uses signaling between 3V and 5V so I'm suspecious of this 0.16V POWER_GOOD signal.
Can someone help chime in (no pun intended), or verify the POWER_GOOD signal voltage of an early 2006 iMac Core Duo (2105)?
THANK YOU!

By the way, I've done AppleOption+PR (from my LCII days!), and have removed the logic board battery, waited, reinserted and retired without success. Thanks!

X2100 won't boot (no display)

I bought a new X2100. Out of the box it ran fine. I just powered it on at my data center and it appears to not post. The fans never calm down, there's no video, and no console output.
The motherboard shows C1 which is normal, I reset the CMOS and it showed C3 which is the bios coming from the compressed nvram image.
The system does nothing with C1 displayed on the motherboard led. I'm at a loss. The machine won't boot.
The primary nic never lights up etc...
The system shows a Green 'OK'. I have tried disconnecting the peripherals with no success.
Any help would be appreciated.

Hello Aaron,
the system is under warranty. Why not open a service case with Sun or your reseller ?
These forums are user-to-user and (at the moment) there is not much experience/expertise with these system. I sure in a few month this will have changed.

Intel D2700DC + Arch won't boot without display

I've faced really wierd (to me) problem running Arch as mini webserver on the Intel D2700DC mini-ITX board with Atom D2700 integrated and NM10 Express chipset.
I successfully installed the system, configured network and started sshd to continue setting up other services remotely via ssh console. Then I disconnected the keyboard and display from the case and put it under the table. After that I was quiet surprised that the system was not starting up anymore.
After some investigation I've found that the system is not booting if no display is attached to the DVI port of the motherboard. If I start the system with display disconnected, I can hear one beep that notifies about successful BIOS POST, HDD led blinks 2-3 times, and then just nothing happens. System isn't booting up. If I attach the display right after that - nothing is seen on the screen, and display is immediately falling into sleep mode. Keyboard is still active though, and if I press ctrl+alt+del - the system is restarting, and, if display was just connected, it boots ok then. Also it boots fine from the cold state if the display was attached to the DVI port at the time of powering on.
As I can assume from the timings and HDD led blinking, the boot process stops right after GRUB is loaded. There's nothing in system log, cause it seems that boot hangs just before the kernel is loaded by GRUB. I'm really stuck and don't know how to work around this situation, because if the display was disconnected when system was powered on - then there's no way to see anything on the screen until next reboot, and if the display was connected - then the system boots OK.
One more thing to notice:
There was an old CentOS installation on the HDD, to which I installed Arch Linux. I've tried to boot it once or twice before installing Arch, and, as I could remember, it could boot up without display connected, on the very same hardware. So I suppose it's definitely something in Arch that is preventing the system to boot without the display.
I guess that when no display is connected at boot time, NM10 chipset completely disables onboard video, and because of this we can't see anything on the display until the system is restarted. But this somehow affects Arch, so it can't boot without any video hardware present.

I'm afraid there's no such option, but it looks like arch isn't booting just because no graphics card is detected in the system when display it disabled during powering up.
There is a couple of similar topics about some other linux distros can't boot without video card inserted ([1], [2]) with some recommendations on what to do in such a case.
I've followed them - including enabling serial console in /etc/inittab, setting nomodeset in kernel line in grub's menu.lst, checking for enabled splash-screens... but that didn't help.
Does anyone know what options should be tuned in order to boot Arch without any active graphics card present in the system hardware?

Ideacenter B540 Won't boot no display with black screen

Hello,
I bought an Ideacentre B540 two years ago and today all of sudden compuer would not boot.
When I press the power button, the only LED comes on is the one on the far right corner at the bottom of the screen.
There is no display of any kind whatsoever.
The system's power goes off only when I hold down the power button for about 3 seconds.
Is there something wrong with the motherboard or the power supply?

Hi paradisehi,

MacBook Pro Retina 15" mid-2012 won't boot in clamshell mode with an external display attached

I have a 15" MBPr mid-2012 running OS X 10.10.1. The system won't boot in clamshell mode (power is connected, lid shut) with an external display attached via an Apple Thunderbolt->DVI adapter. it boots fine if the lid is open. It isn't the adapter or the display since my 15" MBPr mid-2014 boots up just fine connected to the same adapter and monitor. And this system used to boot like this just fine some while ago (probably before it was upgraded to Yosemite). I've reset the NVRAM (twice) to no avail.
Has anyone encounter this? Anyone have a solution? Should I try an SMC reset (always a bit nervous about that)? Might it be a driver issue in Yosemite?
Thanks.

Won't boot with external display connected

My MacBook Pro (circa 1997) won't boot with the external display connected. I can connect the external display (20in flat planel) after it has started, and it works just fine.
I have tried two different DVI cables (one of which I think is a DVI-A cable) and the DVI-to-VGA cable. The result is the same.
During the boot phase I get the tone, the apple logo and the progress wheel. After 30 seconds to one minute those disappear to be replaced by an empty blue screen.

In case anyone wonders, my "solution" was to change to a WB Elements Desktop 3TB (only USB 2.0 is currently available for this model). I miss the speed of USB 3.0, but it's much nicer to not have to remember to unplug and plug in the hard drive each time I boot.
Still hoping to see a proper solution to this (since I don't have the WB My Book anymore, I can't test adaher's suggestion).

Fuzzy Display - PC Won't Boot

Hi there,
I have a friend who was using her PC (a Pavilion a1000 running XP3) when it suddenly gave the BSoD. She hard re-booted, now it gives a fuzzy display and won't boot past the HP logo screen. I can't get into the BIOS setup, or safe mode. It won't get beyond the logo. There are no error codes or beeps. Just freezes at the logo with the fuzzy display.
Before I do anything else, does this sound like something obvious to anyone? Any input is appreciated. And if more information is needed, just let me know and I'll gladly supply. Thank you in advance.

GTifeld, welcome to the forum.
Without the full model number I can't be specific. However, from the models in that series it appears that the computer is 8 years old.
My first thought when I see these symptoms with older computers is a failing/failed power supply unit (PSU). Here is a guide to help you troubleshoot the PSU.
If it appears to be okay, then, check to assure that the memory is seated properly. Over time the memory can shift. Also, it could have failed, as well. While you are at it, check all of the other components and clean inside of the case.

Why won't my Intel iMac boot up, either from the internal hard drive or the DVD drive? It just displays a light grey screen, without any other icons, etc. The fact that it won't boot from the original system DVD is what baffles me the most. Any ideas?

If the C key for Install Disc or R Command for OS X Recovery startup commands are not working, try holding the Option key for the Startup Manager.
see > Startup Manager: How to select a startup volume
If that does not work and you using a wireless keyboard, it may have become unpaired and you need to dig up a USB keyboard to invoke the startup commands.

Bootcamp won't boot when Apple Display is disconnected

When I connect my MBP to my 24" cinema display everything works perfectly on windows xp through bootcamp, however, when I turn my computer off and turn it back on without the display connected, windows won't boot and just switches itself off.
In other words: If the cinema display is not connected, bootcamp wont boot. This is slightly annoying as now I can only use windows on my desk where the display is.

Hatter - I was hoping you'd find this thread. Thanks for your help.
More info: Currently there is nothing on the second drive. I'm not trying to install Windows on it, I just want it for fast access storage, available to Windows programs.   I've re-formatted it a couple of times to see if that fixed the problem, but no luck.
Obviously, I need to read up on what GUID and MBR are.    Do you think it would work best if I put Windows on the second drive instead?
If so, is this the way to do it: I use Super-Duper to make a bootable copy of my main HDD reguIarly, so no big issue there. I've bought Winclone to make a copy of the Bootcamp partition. Can I then reformat the primary drive to FAT to accomplish the same thing as unplugging it? (It would sure be a lot easier than dis-assembling the iMac again).   Then install Windows on the secondary HDD using the optical drive and Windows DVD. Then go back and restore both drives.
I guess once everything's restored, I would use the secondary HDD to run Windows, and use the NTFS partition on the primary drive for my storage.

Startup Manager displays Mac HD but won't boot to it

I have a 2008 MacPro (2x2.66 GHz Dual-Core Intel Xeon) that has been successfully running Bootcamp for a couple years with a Windows XP partition and a Mac 10.5~ partition (actually I can't remember if it was 10.6 or 10.5). We recently made a new partition for Windows 7. (This is in a classroom full of identicle MacPros, but noteably, the problem machine is the teacher's station).
As of today, the MacPro no longer boots into the Mac OS partition. It boots, by default, into Windows XP every time. Holding down option on start up brings up the Startup Manager, and the Mac HD is visible, and you can click on it or tab to select it, but then nothing happens. We tried a bootable external hard drive, but had the same problem with the Startup Manager and an inability to select anything (the keyboard and mouse both seem to work) but nothing happens when you click on your selection.
Once booted into XP, you can see the "Mac HD" option in the Boot Camp Control Panel. You can select it, but then the computer boots back into XP.
I did get the computer to start up off a Mac OS Snow Leopard install CD by holding "C" on start up. I ran "Repair Disk" using Disk Utility and found no problems. I tried repairing the disk permissions, and although they seemed fine.
I tried zapping the PRAM but there was no effect (booted into XP).
I unplugged the computer for a few minutes to reset the "NVRAM". No effect.
I tried different key combinations to attempt to boo in Safe Mode, Single User Mode, Verbose Mode, and none of those things worked, the computer booted straight into Windows XP every time.
I tried holding "d" for a hardware test, but nothing happened. Do you need to be on the internet for this? Because, I also tried, based on some suggestions I saw online, unplugging all peripherals (like our bootable firewire drive) and ethernet cables and not using a third party mouse. No effect.
Finally, I let the Snow Leopar install CD install, and although it seemed successful this had absouletly no effect. It still boots straight into Windows XP. Granted, I did not delete everything for a clean install, as I'm not sure the files are backed up anywhere.

""To update anyone watching this, we tried putting the hard drive in a different machine and still had the same boot issues,""
Are you saying that the questionable HD was put in another computer and THAT computer had the same issue as the Professors?
If so I would just backup and erase the hard drive, reformat and reinstall everything as something buggered up the Boot Manager and your going to take more time figuring it out as to redo everything.
I don't think the HD is going out but you MAY have some bad sectors on the Mac partition, if that's the problem then the bad sector might be in the bootable part and thats why it can't boot. If you want to save the HD have a disk utility do a Surface Scan to make sure.
As far as not being able to boot into Safe mode, etc, if it had a bad sector it won't be able to read the boot part which is why you can still boot into the Install DVD.
You know, looking back at your original post if you can't boot into safe mode while pressing the Shift Key after the bong, can't boot from an external HD or any of the other ways, then I would say it's a hardware problem.
Like I mentioned before, if you can put in another Dual boot HD from another machine into the Professors machine and it still won't boot into both OS's then you have confirmed it's a hardware problem.
Good luck...

Satellite m300 won't boot! please help!

Hi,
I've got a bit of an issue here.. I have a Satellite m300.. a white one..
and it won't boot... I've had this very issue before but it turned out to be an external USB HDD that stopped it from booting up but now even with everything removed it still won't boot.
And it was fine until yesterday, it just gave up.. I am away from home for work so I have all the work stuff and unfortunately without my recovery cd, but my guess is that it won't even read it..
So this is what happens..
turn on..
all light come on.. including power and all the white lights around the keypad..
and then maybe 5 sedconds later caplock and numlock(?) green lights flash..
then it's a dead still.. no HDD activities or sound.. just dead quite..
the screen remains black blank through out..
it seems to get stuck here before reaching the post screen.
i thought the power button usually took more than just a push to turn off? it instantly swithces off with a single push of the power button..
I think this laptop is like on sleep or something and can't seem to wak up.. maybe?
And it has vista.
Please help.. I have some important work files I need to recover at least before formatting..
and that has to wait till I get home which won't be for a month or so..
which also lets me take it back for warranty as well..
any help appreciated!!!
cheers,
Min

Assemble PSU connectors ,only one DIMM module and graphics card and turn it on and se if you get a post .
Just removed all components. I reset the CMOS. I then reconnected the 20pin and 4pin, 1 stick ram, and the video card (no ide devices, no mouse, keyboard cd drives) and the monitor doesn't show up. I also tried another monitor so it isn't the monitor.
Could it have a bad AGP port?
Any other suggestions? I am thouroughly stumped. Also the power and reset buttons don't work no matter what configuaration I put the front panel connectors in. The Power LED is lit up and it doesn't work and the reset light is off and it doesn't work.
Also noticed one of my fans connected to one of the two other fan pins on the motherboard isn't working.
What a nightmare.

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!

MacPro won't boot-up...I think it's hardware related

Sorry, this is detailed, but I figured I had to explain everything I've done so far and the issues I've had. Thanks much!
My MacPro won't boot up. Initially I thought it was a software problem, and went through this thread looking for help. After a while, I came to think it wasn't the OS but a hardware problem. Here's why:
The initial problem was that I couldn't login to OS X (Lion). It started with the screen flickering, and freezing up. One time I logged in, and there were these uniform dots across my screen, and a black border overlaying the screen. I restarted, and that was when I couldn't login at all. It would go the gray screen with the dark gray Apple logo. The sundial would appear below...and then suddenly freeze. At that point, nothing.
I tried to boot into Safe Mode, but this also didn't work. The same result.
I then decided I'd do a clean install from the Install DVD and overwrite my boot drive (everything is saved onto a RAID Array). However, I couldn't load the OS installer.
I then thought maybe it was the HDD itself (the boot drive), so I bought a new one and tried to format and install. Again, the same thing. The DVD drive would activate, the gray screen would appear, and then it would freeze at the sundial. But this time, the dark gray overlay would come on screen, with the small box that told me to hold down power key (the one in mutliple languages).
So I then began to suspect the problem was deeper. I ran the Apple Hardware Diagnostic test. (I disconnected everything except the keyboard and the display.) The quick version showed everything was fine, but the extended version came back with some varying results.
First, my specs.
This is a MacPro 3,1.
24 GB RAM (8GB installed by vendor, 16 GB recently installed by me)
Bay 1 - Unformatted new HDD
Bay 2 - Slice 1 of RAID Array
Bay 3 - Slice 2 of RAID Array
Bay 4 - Formatted HDD for Storage
When I ran the first test, it was as above. Here is the error message I received:
4MEM/62/40000005: 0x79600ff18
This made me think it was a memory issue. So I took out the new RAM I had recently installed and ran the test again. I got this:
4MEM/60/40000005: 0x79650d18
So I took the old RAM out and put the new RAM back in. I also put the original, formatted HDD with OS X back into Bay 1. Here's what I got this time:
4SNS/3/4000000: TMOP-128.000
The new kind of error led me to think the problem was the old HDD and old RAM (after all, when I used only the new RAM, I put the old boot drive back in). When I ran the test, with the unformatted HDD in Bay 1 and the new RAM, I got...no error message!
So I restarted my system, hoping I could load the Install DVD now and install Mac OS X on the new HDD in Bay 1. But...nothing. Same as the original result. Gray screen with a freeze on the sundial, and then gray overlay telling me to shut down. Aaargh!!!
Someone suggested trying to login to Single User mode. I was tried and was able to do that. But, what do I do from there?
So I rebooted, and then tried to login when holding down the option key. It came up with the option to load the Install DVD. I said yes, and of course, same result as before.
So, as a last step, I put my old HDD back in and started the system holding the option key. This disc is a dual boot drive with Windows 7 on another partition. It gave me the following options:
Mac OS X HDD (my Lion install)
Windows 7
Recovery HD
Install Mac OS X (DVD)
For kicks, I chose Windows 7 to see what would happen. It actually logged me in! ... but it was like I was in an old safe mode in this sense: the screen size was the smallest available (that is, all the icons were big).
This makes me think that maybe (again, maybe) the problem is the video card. (Nvidia GeForce 8800 GT) This might explain the flickering and freezing I initially had when I could actually login. But...really, I'm at a loss and don't know if I should take the time and money to get a new video card.
Any suggestions???
Thanks!
Naveen

Windows 7 DVD has a decent memtest and you are in Safe Mode probably due to Windows didn't shutdown gracefully.
You can also use chkdsk or WD Lifeguard to certify all the disk sectors are mapped out if they need be.
8800GT: you have heard of the 10 minutes in over for 350*?
But you might want a new card anyway.
Vendors and RAM. Well it was working but buying RAM esp FBDIMMs and my guess is you have some 4GB DIMMs. Also mixing sets or brands can work most of the time, but not always.
RAM probllems result in dirty files and other errrors so fix the problem, make sure you have a good pair and no errors. Or more. And then try clean install.
Windows 7 w/ AppleHFS.sys and AppleMNT.sys does not like an Apple array to be present. MacDrive gets around that and allows mounting - and avoiding BSODs.
Cheap as I have found, highest quality though, 667MHz so they run 4% slower is all, if you need one good set:
2x2GB FBDIMM DDR2 667MHz
http://www.amazon.com/BUFFERED-PC2-5300-FB-DIMM-APPLE-Memory/dp/B002ORUUAC/
Lion Recovery Disk Repair? you did or didn't?
Lion installer: hopefully you kept the ESD package for later re-install (without having to download and all that bother).
Some people play musical chairs with the Risers and DIMMs and DIMM slots. Or just RMA and get new sets but I would try with just half the 24GB or less, then test with half the 16GB set. To have one set it would be one DIMM in A1 and B1.
And of course reset the SMC - hitting power button 10 seconds while unplugged (and no devices or cables connected).

GX Won't boot, no display.
