Satellite A60-672 hangs and will not boot up properly

Hi,
I have a Toshiba Laptop A60-672 it had been running slow but now when I turn the laptop it goes straight into the option screen where I choose safe mode or last known good configuration, every option I choose goes into the windows screen as if xp is loading up the blue bar runs across the bottom of the screen then you get a quick click of a blue screen then it reboots back to the screen of safe mode and last know good config ??
Can anyone advise me
Thanks and Regards

Hi
The same happens on my brothers notebook because the files and sectors on the HDD were corrupted. This is happened after trying changing the partitions size.
I have booted from the original Microsoft Windows booting CD and went to the reparation console. I think you have to press the R to start the reparation in the Windows setup.
Then in the reparation console I have used the chkdsk /r option to solve this problem.
And I was successful try it!

Satellite L300D-13S crashed and will not boot up

I received an alert on my Toshiba L300D -13S via the Toshiba Tempro alerts to download the latest BIOS update. I downloaded the update and started the install, during the install the PC crashed and froze for about 30 seconds the lost power completely.
Since this the laptop will not boot up, there is power to it as the battery and plug lights are on also when I press the power button the fan starts and the keyboard lights flash but then nothing. The laptop does nothing the fan runs for a short while and then powers off.
I'm no expert but in my opinion there must be something seriously wrong with it, any advice would be greatly appreciated. The laptop is still under warranty so as soon as I get some kind of confirmation that this a serious problem I can send it off for repair.

I contacted Toshiba's helpline and spoke to some one in the tech department, they said that the BIOS was corrupted during the update hence the problem with the start up.
Apparently this is not good and could result in a new motherboard if the BIOS cannot be flashed back to a non-corrupt state. I'm not overly technical when it comes to PC's, fortunately my laptop is still under warranty and is in the Toshiba repair centre as week speak. I did however research possible repairs for this fault and from reading forum posts as searched for on Google there are some things that you can try although they can be risky in terms of causing further damage.
The most eligible possible fix that I seemed to come across was to download a DOS boot file, the relevant BIOS file and a flash program, burn them to a CD then boot the laptop into DOS and run the flash program, re-flashing the BIOS.
**Again as stated before I'm no expert so please don't take the above as gospel, I'd look into it and make sure you get expert advice before going down this road.**

Imac crashed and will not boot up

So my iMac crashed and will not boot. The power will come on and when it switches to the boot sequence it powers off. I bought Black Tie protection at Best Buy but when I took it to them they shipped it to Apple. The problem was never fixed. Apple said it was a software issue to reload the OS. Well i did that and not even a day went by and it is doing the same thing. Any suggestions would be helpful...

I agree with BGreg that you should run Apple Hardware Test , however run it in Extended Mode. If no errors turn up run it several times. It's a lengthy test so be patient. Also here is what Apple says about your symptoms in Gray progress bar appears under Apple logo during startup.
I hope you have been backing up your system, if not then if you can boot into Safe Mode as suggested you should immediately backup using either a clone or Time Machine. That should be the #1 priority to preserve your data.

== This happened ==
A few times a week
== Not sure when it statrted

Hi.
When this happens, please press CTRL+SHIFT+ESC and see how much RAM and CPU Firefox is using. If they're sky high, then... Well, that kind of issues are, unfortunately, more common and the we'd like. Thankfully, 99% of the cases are very easy to solve. However, you do need to diagnose what your exact problem is. Do this:
#run Firefox in safe-mode to disable all extensions and plugins. If this fixes your issues, be them with RAM or CPU usage, then you know it's a problem with plugins or extensions. Proceed to number 2. If safe-mode doesn't fix the issues, then read bellow, after this list;
#update all extensions and plugins in your Firefox. If this doesn't solve the issues, proceed to the following number;
#disable all extensions and plugins in your Firefox (not running safe-mode). Being certain that, as in safe-mode, the problems you're having have gone away, enable one plugin at a time. You should be certain that you WANT that plugin to be enabled, so keep your overall number of plugins as low as possible. When you encounter the problems, you know you've found a problematic plugin, so disable it for good. Keep enabling all plugins (except problematic ones) until you've gone through them all.
#enable one extension at a time. Again, be certain that you WANT that extension to be enabled, so keep your overall number of extensions as low as possible. When you encounter the problems, you know you've found a problematic extension, so disable it for good. Keep enabling all your extensions (except problematic ones) until you've gone through them all;
#you're done! You've fixed your problems with problematic add-ons.
Ok, if disabling all extensions and plugins through safe-mode didn't work to bring Firefox's CPU and RAM usage to good levels, then you have different issue. The most likely scenario is that you have a third party software running on your computer that is messing with Firefox. Do as follows:
#do a virus/malware check on your computer. If this doesn't fix it, proceed;
#disable all software running in the background that you don't want to have running in the background (in windows, this is done by pressing WINDOWS+R in your keyboard, typing "msconfig" (without the commas) and pressing enter. Now, under the "Startup" tab, you can uncheck the software you don't want, and reboot your system for changes to take effect. If you're unsure of what software you want running, ask someone with more experience). If this doesn't fix you issues with Firefox, proceed;
#check your firewall/antivirus/security suite for enabled functions/features that you don't want and/or may be conflicting with Firefox. You'll find that these features are most likely tied to Internet Security features, such as link scanners or URL checkers and the like. If you're not sure they are conflicting with Firefox, simply try to disable to see whether or not that's true. As long as you don't browse the web with your antivirus completely off and your firewall completely turned off, there should be no problems. If this doesn't solve the issues, proceed to the following number;
#check your operating system security options, mainly advanced options that are not configured by default. While it's very unlikely that this may be the cause of the problem (after all, it's the last item on the list), it's remotely possible. If this doesn't do it, I'm out of ideas. Except make sure you've followed my instructions correctly.

Why does my Logic Icon have a question mark over it and will not boot up??

Why does my Logic Icon have a question mark over it and will not boot up??

Because it was moved, renamed, or deleted, and needs to be put back or reinstalled.

My home imac has crashed and will not boot up.

Hi
My home imac has crashed and will not boot up and I'm not sure where to start.
It wouldn't shut down properly so I turned off the power, and now it won't go beyond the apple logo and timeer when I try to restart it.
It is an imac (4 years old), Intel, running OS X, not sure which version, but probably the latest.
Thanks
Carol

I would first reset the SMC:
Shut down and unplug the Mac.
Keep the Mac unplugged for at least fifteen seconds.
Plug the Mac back in and do not turn it back on for at least five seconds.
Press the power button to turn the Mac back on.
Then I would reset the PRAM by rebooting the iMac while simultaneously holding the Command-Option-P-R keys until the machine restarts a second time.
Let us know if these two procedures don't solve the problems.
Hope this helps

Pavilion g7 laptop screen flashes colors and will not boot

When I power up my laptop, the screen flashes different colors and will not boot up

The service manual is for the G7 series notebook and is not exclusive to the g7-1368dx model. Different models within the G7 family uses different hardware and supports different hardware upgrade paths. This means that an item listed in the service manual is not necessarily supported for every model in the G7 family.
Is the notebook's product number A7A46UA?
If so, the motherboard this unit came with is the 649948-001 as listed in the service guide. All the parts for this unit can be found here.
I searched HP PartSurfer for the part number 669690-001, the A8 processor, and expanded the note at the bottom of the result page to see what units came with this processors. I reviewed three different models and each had the motherboard 649950-001.
The units that shipped with the A8 processor had a different motherboard than what the units that shipped with the A6 processor.
Due to A8 units having a different motherboard than the A6 units, I suspect that the motherboard your unit has does not actually support the A8 processor. Sorry.

My Airport, even after a Factory default reset, just has a rapidly flashing white light and will not boot up. What should I do?

Thanks for you response! I have had it for about 5-6 years ... don't know if that is "vintage" or not. I just got back from our local Geneis Bar and they declared it "DOA." So, I've got a new one and getting ready to install. Thanks, again!

When I turn on my ipad the cursor keeping circling and will not boot up

Pavilion DV6 1320sl stopped working and will not boot

Pavillion DV6 1320 was beiing used. Had been running hot - fan was on all the time. The left mouse pad button was pushed and the screen went black with a blinking cursor. It will not boot. There have been no software or hardware changes, a nd it hasn't been dropped. Win 7 64 bit is installed and it has run OK since new in 2009. There are no error messages. Turning off the machine is with i single depress of the power button.
Turning machine on disk=plays BIOS message to sel esc to enter BIOS. From BIOS, system check of memory, hard disk and hard disk SMART have been run. All passed.
No other BIOS function works - ie f9, f8 ,or f11 all do nothing.
I ran the hard reset to no avail. The buttons glow but the screen remains black with blinking cursor. I followed the HP guideline for trouble shooting a black screen with glowing buttons. Didn't help. swapped each memory bank and tried each possible bank configuration. Didn't help. Replaced the RTC battery and reset BIOS to default. Didn't help. Hooked up another monitor but that didn't help either.
I did not try system restore, but f11 doesn't work and booting from cd was unclear as to results - I didn't have a boot disk so I used disk 1 of the restore set. Nothing happened.
I used canned air to blow out the cooling holes but they didn't seem clogged (although the fan was on much of the time these past few months).
I'd appreciate any ideas. Perhaps a component has been burned. What would be the visible symptoms of a CPU failure? What about the chip set - if the Northbridge fails, what would it look like?
I don't think it has actually loaded and is a video chip failure but who knows? I'm open to suggestions.
Rob

Thank you and yes it is an Airport Express.
Reset router; could not locate the unit using the Airport Utility.....took back for an exchange under warranty as it was only a week old....no problems at store - exchanged for a new one

Macbook Pro will not load OS and will not boot from Install Disk

When I try to turn on my macbook pro it goes to the gray logo screen with the spinning gear however it does not progress from there and then after several minutes it proceeds to restart itself and the same process repeats itself. I have tried to boot into single user mode with success and have run /sbin/fsck -fy and that has returned that the volume appears to be ok. However, when I hit reboot it returns to the same process of the gray screen and spinning gear to black screen which repeats. When I boot into verbose mode it progresses to AppleYukon2: RxRingSize <= 1024, TxRingSize 256, RXMAXLE 1024, TXMAXLE 768, STMAXLE 3328 then it stalls for several minutes and then it shows continuing
synchronizing disks... Killing processes
then it says some other stuff to fast to read.
When I try to boot from the install disk it will not boot from holding the c key it goes through the same aforementioned cycle. When using option to boot I can see the Disk then when I select it the cycle happens again.
Also I have XP installed and I am able to boot into that successfully. Any help would be greatly appreciated.
Not sure if I left anything out

Welcome to Apple Discussions.
Do you have multiple Accounts defined on that system? The last time you successfully were running, did you run from the Account with Administrator privileges?
Do you have another computer from which you could boot and connect the Macbook Pro in Target Disk Mode to take a look at the drive from your working machine? Perhaps you can run Disk Utility from the working machine and point to the hard disk on the failing Macbook Pro.

Mac Pro Processor heating and will not boot

Hi All
I have a 2009 Mac Pro with dual processors, this has been a great system until recently it started to shut itself down after around 20 minutes of use, I tracked this to a processsor getting too hot and shutting down. I air dusted the unit and replaced increased the fan speeds. Now the mac pro will not boot. As soon as I insert the power the motherboard flashes red and will not power up the system. Is there something I can do myself? Can I clear the mac bios? Any thoughts or advice would be appreaciated.
Cheers

thanks Hatter, I appreciate your advice.
The system is running 10.6.2, or was running.
I tried the SMC reset:
SMC Reset using "unplug, hold power for 5, release, plug in
SMC Reset using "unplug, hold power button, plug in, release
No change either way.
What happens is, watching with the case open, when I plug the power cord in and two red lights flash on the motherboard "CPU A" and CPU B". And nothing happens from there, no fans, nothing.
I wil try to remove the heatsink if I can find the right tool.
Do you have any other thoughts?
