HP G7000 G7096EA Won't boot, no post/bios, blank grey screen

My HP G7000 G7096EA Won't boot, no post/bios, blank grey screen - It does appear to get into windows after return is pressed, albeit with blank grey screen.
I've reseated the RAM/harddisk, tried the power button reset method. Left it overnight with power battery/power.
I'm at a loss now with what to try. It does look to be a dead graphics chip, which is a shame and will probably put me off HP for life!

Ok, I've stripped it down to diagnose. Due to the piss poor cooling on the graphics chip, it's fried itself and melted the solder underneath.
This was actually the second laptop I had off HP as the first broke within a very short time.
Needless to say, I'll be buying from Dell in the future! What a crock of **bleep** HP are.
Oh yeah! And HP wanted £16 + vat just to speak to some outsourced crappy call centre!

20" imac won't start up-flashes between blank grey screen and black screen

20" imac
2GHz Intel Core 2 Duo
Was running system 10.5.8 just fine. Worked great.
But then I wanted to give the imac to a relative. And so, I tried to boot from the original grey mac install dvd to wipe the hardrive and set the imac back to factory specs.
But it wouldn't boot off the dvd. All It would do at restart was to flash slowly back and forth between blank grey screen and black screen. So, I tried the Leopard update dvd. Same results. So I zapped the pram and tried again. Same results.
If I just pushed the start button tho.. the imac would start right up and run fine. However, I didn't want to give it to someone else with all our information on it.
I finally restarted it and held the "T" key to turn it into a giant firewire drive, hooked it up to our other 20" imac, and used the disk utility from the second imac to erase the drive of the first imac. Then I inserted the grey install dvd into the second imac and selected the drive of the first imac and ran the install process.
Now, the first imac won't start up at all. Just a continual grey screen for a bit, than a couple of buzz sounds in the machine and then the black screen... than back again.
It ran great before I erased the drive and re-installed OS 10.5
What's wrong? How do I get the machine to either boot off the install cd?

So, I've figured out a little more on the first machine. It's a 20" 2.6 GHz Intel Core 2 Duo running 10.5.8.
It ran great. But, I wanted to erase the hard drive and reinstall the OS system before giving it to a relative.
I found that although the optical drive would read and write to normal cds and dvds, the machine would NOT boot from the grey start-up disks I had on hand. ( I have two imacs, and I tried both sets of dvds without success.)
I zapped the PRAM, and used disk utilities via firewire connection from my other 20" imac to check the hardrive and make repairs. Disk Utilities couldn't find any problems. So, using disk utilities from the other imac, I erased the first imac's harddrive and then used the install dvds on the second imac to install the original OS to the hard drive of the first imac.
(looking on the hard drive of the first imac, I can see all the contents)
However, the first machine will not start up. It just switches from grey....to black..... then grey..... and then black again.... over and over
Why won't it boot from the newly installed OS on it's own hard drive?
And Why won't it boot from the original install dvds?
How can I get it to start up again?

My mac won't boot up, just has a white screen with a blinking ? mark, any suggestions?

my mac won't boot up, just has a white screen with a blinking ? mark, any suggestions?

this usually means the software and hardware can't find each other for whatever reason the following article addresses this issue:
http://support.apple.com/kb/TS1440
can also do apple hardware test, following article on that:
http://support.apple.com/kb/HT1509
if you can't access the apple hardware test in the above article you can also do fsck command to check the hardware as well, following article tells how to do that:

hopefully one of these articles helps w/ resolution!!

Macbook won't boot...kirr kirr sound with blank grey screen

Hi everyone,
I am visiting a remote part of the world with no mac support at all. I have no install discs either . All of a sudden my mac froze and so after a while I restarted. Since then, it won't boot. I could hear a kirr kirr sound somwhere close to slot drive...I tried to restart xp from bootcamp partition but besides blank grey screen it won't go further (not even ugly question mark or rotating circle)..I hope my hard drive has not crashed because i have my entire life on my computer with no backup either.. it tried restarting in verbose mode (cmd+v?) but effect to that either..Someone please suggest something..I have winxp cd and other random cds and dvds...
Help

Hi Gregory,
Thanks for such a quick response. I think my luck ran out. I did a lot of work while I was away and couldn't back up. I figured out that weird sound (sounds like a termite) comes from the hard drive. It took the hard disk out and the noise is gone and question mark (which probably symbolizes hard disk not found) is back.
Now that I am almost sure it is a damaged disk problem, I just worry whether is would be possible to retrieve data in future. I am going to find a external enclosure (i might be able to find it here) and try it on a pc with macdrive. I don't have much hope because this kirr kirr sound gives me the feeling that the disk won't be detectable. Any ray of hope. I will buy any piece of software that gives some hope.

Thank you

The following support article is somewhat outdated. Where it refers to booting from an installation disc, you should boot from your recovery partition (if running 10.7 or later) by holding down the key combination command-R at the chime.
Mac OS X: Gray screen appears during startup

My G4 Apple PowerBook will not boot further than pale blue/grey screen displaying "flashing file symbol / flashing ?"

My G4 Apple PowerBook will not boot further than pale blue/grey screen displaying "flashing file symbol / flashing ?"
Last previous action: Used Firewire cable and "Target Mode" to copy files from G4 eMac to the PowerBook.
I worked from the eMac to the PowerBook, making the PowerBook the "Target". Files seemed to transfer OK. Won't boot from InstallDisc. Holding down T on startup results in Target mode screen. I have a G4 iMac and a G4 eMac. Can I use either of these with Firewire cable to boot-up my PowerBook ?
I'm new to using this Communities & Forums Help. Can someone please help me to get going again ! ! Thanks for your time. Graflood

Hello,
It sounds to me like the PowerBook is stuck in target disk mode.
It's expecting the iMac/eMac to be there when booting. Seeming it's not attached, it will show a flashing folder.
If your PowerBook internal drive is bootable, then simply hold down the option key when booting and select it's internal hard drive. That should boot your PowerBook into Mac OS X.

Sounds like you may have a harddrive issue. You are probably going to need to get that changed out and then install the OS X again to get it going.

Mac OS X: Gray screen appears during startup - Apple Support

My MacBook pro will not startup. I get a blank grey screen no logo appears so I can't chooseadiffer t drive nor boot from DVD. Safe mode and verbose mode also don't change blank screen.

It was running slow with the colored spining appearing often. This started happening weeks ago with Yosemite so I formatted the disk with the DVDs that came with the mid 2011 MacBook pro, 10.6.8. I then installed Yosemite on an external drive and this morning i was booted from the external hd with Yosemite and it stopped recognizong mouse clicks so I forced a restart and now I'm stuck with the blank grey screen. Safe mode and verbose mode also do not work.

Lao Bo,
yes, you can locate and copy a file from your HD to a USB key using UNIX commands. If you know the exact name of the file which you’re trying to locate, try this:
find / -iname filename -print
This command will search your entire internal disk for the particular filename. If you know that it’s within a particular user account, then you can save search time with this variation:
find /Users/username -iname filename -print
Either variation of this command will print all files found which have the given filename. Presuming that you’re able to identify the correct file, you can copy it to a USB key using the command
cp -p filename_returned_by_find /Volumes/USB_volume
If you’re not sure which volume name your USB key has, this command will show you what the possibilities are:
ls /Volumes
Please let me know if you have any trouble with these commands.

My system won't boot past POST after I plugged in my new SATA drive. (SATA noob

I have a MSI K8n Neo 2 Platinum mobo with a Athlon64 +3500 and 1gig dual channel DDR 400. I currently have 2 drives set up a IDE primary (MAxtor 6Y120) and a IDE slave (Maxtor 6L080).
I recently purchased a Maxtor DiamondMax 10 6L300S0 300GB Serial ATA 7200RPM Hard Drive w/16MB Buffer.
It is my first SATA drive ever so non the less I am a newb. I want to use it as a non Raid media storage device while my primary IDE remains my boot OS drive.
I plugged the SATA in to the sata one port and powered it. I enabled the SATA in the bios with RAID disabled. When the system boots up it does the memory chech and lists all the IDE devices. Then it says "Detecting IDE drives..." and just hangs there. The new drive spins so it definatly has power but occasionaly it make occasional clicking sounds.
Once it actually booted up and windows detected it. I decided to reboot it just to play it safe but it never would get past post screen again. I can boot up the system normally when I unplug the SATA cable.
Please help I need to know if I am doing something wrong or I should RMA the drive. THANK YOU!

Boot stalls in bios at Raid setup. Tried enable raid with no drives enable , system booted twice, turned off overnight, then failed to start the next day. Will only restart with a cold reboot. Hot reboot produces a long BEEEEEP & power is on but nothing happens no post nothing.

Pavillion dv9580us turns on, but won't boot or POST

I have an HP dv9580us that I bought about 2 years ago. It had been working well until a few days ago. Now when I turn it on the lights come on, the fan turns, but nothing happens. A few seconds later everything turn off, then the lights come back on again, and it just stays like that. No beeps, no blinking lights (they turn on but don't blink), no sounds, the screen completely blank all the time.
So, I think the BIOS is not even making it to POST at all. I already tried re-seating the RAM, took the battery off, took the CD drive off, re-seated the HD, and reset the bios.
Any ideas on what may be the problem? I suspect the motherboard, but on most cases I read about the system does boot or POST.

According to the result of your tests, you arer pretty sure that there is a CPU or Motherboard failure.
Not easy to say which one fails. Maybe both!
If your computer is under warranty, don't hesitate!
You can extract the HDD and make a backup of it before you send the computer.
I would recommend using a USB adapter that can connect your internal hdd (now external!) to the USB of to another computer.
Modern USB adapters for HDD can do SATA and (P)ATA. They are even shipped with an external power supply so that you can power on your hdd.
If your computer is not covered by any warranty, well, that's harder. You could try to extract the CPU and replace it to see if anything goes better.
Or you could just purchase a new computer and transfer your current data to your newer computer.
There are even some tools that allow you to transfer the data AND the system+applications directly to your new computer so that when you power it on for the first time with the transferred configuration, it can boot enough of Windows to detect the new hardware.
I used to use Qualystem ubiboot to do so but now that Qualystem has been acquired it seems that this tool is not available anymore (or with a larger/more expensive package). There was a company from New Zealand that had a similar tool...
Good luck

My dv2000 won't boot or POST.

My HP Pavilion dv2000 won’t boot… on powering up button all LED indicators remain solid on (blue), including the QuickPlay, the wireless indicator is orange of course. Cannot access the BIOS. Also the hear the cranking noise by the CD drive… and that is it. Nothing else happen. The screens remain dark. I tried a hard reset: nothing. I tested the memory modules, had drive and cd drive with another laptop and they all seem to work fine. Lastly I took them way and powered on; I still got the same result. I have no idea what is going on. Any help?
HP Pavilion dv2000 - Window Vista – no longer under warranty

Hi !
Seems that there is possible failure in the motherboard already because you can't even boot into BIOS.
Try a Hard Reset first. Remove the battery and unplug the charger. Then press and hold the Power Button for about 15 secs. Put the battery and charger in, then try to power on.
You can also try to reset the BIOS by removing the RTC battery, wait for about 10-15 secs then put it back again then power on the notebook.
If none of these would work, I'm sorry to tell but the notebook needs to be serviced.

My 27" imac won't boot in normal mode. The screen stays white. I have upgraded to Yosemite. However, the computer does boot in safe mode. Could this be a virus related issue or possibly a video card issue?

My 27" iMac will not boot in normal mode. The screen stays white. The computer will boot in safe mode. Could this be virus related or is it possibly an issue with my video card. Before this happened, my computer screen was flashing weird things and the computer would unexpectedly power down.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

My iMac won't boot up it has a gray screen and makes a steady beeping sound

My iMac won't boot up it makes a steady beeping sound and has a gray screen, occasionally it shows a picture of a file with a question mark blinking in the center, can anyone help

The blinking question mark indicates that the firmware could not find a valid Operating System on your machine.
Your harddrive may have failed. Your filesystem may have bcome corrupted.

IMac won't boot from HDD - stays at gray screen

Quite simply, the iMac that we have in the house won't boot. It just gets stuck at the gray screen with the apple and the loading wheel (which is moving, so it's still not "frozen" per sey, but it sits there for going on 20 minutes). We have tried booting it in Safe Mode, which only succeeds in displaying the loading bar, but the computer still gets stuck. Single-User Mode works, but the fsck -fy command says that there are no errors. Booting from a Disk also does not work - we got it to get to the Setup Manager, but choosing the disk just freezes the computer. So we can't get into the Disk Utility. Loading in Verbose mode, the commands stop in the middle of "Running fsck on the boot volume", specifically "Launchcti: dubios permissions on file (skipping): /etc/mach_init.d"
The operating system is 10.6 something we believe, but we can't find out because we can't start up the computer. It is at least 10.6, if not newer.
Any ideas what's wrong and what could be done to fix it? We don't know a huge amount about Macs (although my brother knows a bit more about unix-based systems than I do). Any help would be appreciated!

Are you saying you haven't been backing up? If so and you have performed all the steps in the letter and reached the final step that says to do an erase and install then yeah you will lose all your data!
If you have not been backing up I hate to say it but this will be an extremely valuable lesson on why you should. That being said I'd also recommend bookmarking and reading the following 3 MacWorld articles on backing up, IMHO the common thread is not only should you be backing up but that you should do redundant backups.
Backup Plan I
Backup Plan II
Backup Plan III
Personally I use Time Machine and Super Duper on 2 seperate EHDs to backup daily.
