OS won't start after PRAM reset

I was having problems with my battery, so I tried to reset the PRAM to see if that would help, but now I have a whole new issue...When I try to start up my computer, I get a circle with a slash through it (a symbol that usually means 'no'). This shows up right after the apple logo when I try to start up my laptop.
I used disk utility on my installation cd to check if there was a problem with my hard drive, but it said it was ok.
What did I do? Do I have to reinstall my OS, will that even help?
Thanks for you help.

TS3694 MY PHONE WON'T START AFTER A RESET

My phone won't work after i reset all contents

Try DFU Mode Restore. Open iTunes on computer. Connect iPhone to computer with USB cable. Hold both Home and Power button, after exactly 10 seconds release the Power Button, keep holding the Home button until iTunes recognizes iPhone in Recovery Mode, usually about 20 seconds time. If the iPhone screen is black, blank this is DFU Mode. Click the Restore button of iTunes. DFU Mode can be difficult to enter sometimes, just keep trying. DFU Mode is a black, blank screen with iTunes saying Recovery Mode.

Mac Mini won't boot after PRAM reset

My mac mini has been running very slow, VERY VERY SLOW, then it would seem it would catch up with itself and run fine for a few minutes, then slow down again. It got to the point where I would have to do hard resets, but it still wouldn't work all that great. So I read on here to do a PRAM reset, which I did by holding down controloption+PR, and i got a gray screen with a status bar. But now the mac won't even boot up, even when I try safe mode. I turn it on, and i hear the start up tone, and get to the gray screen with status bar, but then it just shuts off. Does anyone have any suggestions?

From your user guide:
1 Disconnect all external devices from your Mac mini, except the keyboard and mouse.
If you have an Ethernet cable connected, disconnect it.
2 Restart your Mac mini while holding down the D key.
3 When the Apple Hardware Test chooser screen appears, select the language you want
to use.
4 Press the Return key or click the right arrow button.
5 When the Apple Hardware Test main screen appears (after about 45 seconds), follow
the onscreen instructions.
6 If Apple Hardware Test detects a problem, it displays an error code. Make a note of the
error code before pursuing support options. If Apple Hardware Test doesn’t detect a
hardware failure, the problem may be software-related.
If this procedure doesn’t work, you can insert the Applications Install DVD that came
with your Mac mini to use Apple Hardware Test. For more information, see the Apple
Hardware Test Read Me file on the Applications Install DVD.
When prompted, choose the extended test.

G5 WON'T START AFTER SMU RESET

Hi!
my G5 won't start... tried a lot of stuff to make it run - i.e. swop feed cable (a big trouble to get one like it); rest SMU; connect it to another mac via firewire -, but nothing. only the start_up light is on.
any ideas?
thanks,
strawb

Unless your G5 is one of the dual cores you have a PMU not an SMU. To reset follow the directions here:

IPod won't start after hard reset - help appreciated

I had a problem with syncing my iPod with iTunes. I connected and it strated syncing alright. After a couple of seconds everything froze. Smart as I am I thought there might be some errors on any of my disks the syncing process is reading from. Couldn't find anyhting though. My secodn guess would that I just bought a new external hard drive to which I transferred my library (maybe the iPod didn't knwo where to look).
So my best guess was to perform a hard reset and re-sync everything. So I hooked up the iPod and quickly pressed the stop syncing button before nayhting could freeze. That worked well. You probably can guess what happened when performed the hard reset.....everything froze. And now.....my iPod is trying to restart, but at a certain point I hear the drive disconnect and starting up again. This keeps repeating over and over again. Hooking it up to my macbook has no avail. Any suggestions?

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

It is very ikely that there is no way to recover any data from the iPod

" I tried getting the solution online and it said, reset your pc and I did."
Just what solution was that and where was it? Stating that a solution was online is a truly broad statement as it encompasses the entire internet that is accessible to you.
If you made the mistake of using the Windows 8 refresh utility, then your data is gone.
Provide some specific information so we can try to help you.

E5 won't start after multitasking freeze

hi,
my E5 is shut itself afer using Opera Web + music + Palringo
i can't turn it on after, i need to wait for about 4 hours or more before starting it = it as soft reseted alone but how can i accelerate the process if i can't even turn it back on !
ps : nokia review advice for nokia E5 don't buy it ... go to Blackberry if you can !

December 21, 2010
To whom it may concern:
/t5/Eseries-and-Communicators/E5-won-t-start-after-multitasking-freeze/m-p/840827
The thread looks familiar to me. I just came from Nokia Care Center a while ago and left my Nokia E5-00 phone there with the same problem as everyone else on the thread.
I am from the Philippines and my Nokia E5-00 was made in Korea, sent to Hong Kong, and then sold here in the Philippines. That is a lot of cost saving activities to do.
I previously had my first Nokia E5-00 a week ago, Monday. It felt like I am the happiest man in the Philippines. You know, the "I have a Smartphone!" proud feeling of a young man.
But all excitements turned into saddening experience. My contacts are not accessible from theMenu and the Shortcut (default: right selection key) making it inconvenient to create a message or call a contact.
That was a different issue. So I made my phone replaced and last Sunday, 2 days ago, I had my new Nokia E5-00 unit.
Yey!
The contacts were good as all other applications were.
Then, I started having problems as everyone else in the thread experienced. The phone had a bad restart habit and it was, in fact, irritating. It was tolerable at first. Not bad for a replacement phone. I was not much bothered with the restarts.
Then, I was able to start utilizing GPS, like I would get lost. It was an amazing experience for someone here in the Philippines. I was proud to have a good working GPS in my phone!
But, unluckily, 30 minutes after the fun. I set my phone to go back to work and WALAH! My phone shuts down after transferring some files. Good thing my Nokia E5-00 finished all transfers before dying out.
It was not quite the Nokia Smartphone I expected. And, that was really disappointing. Thank you im_mobile for the term.
I did not expect to see these much people complaining problem with Nokia E5-00. Same as everyone else experienced.
How should Nokia fix this? I am not in the position to say this, but Nokia should (1) recall these defective Nokia E5-00 products (Thanks magnum_jon) and (2) replace all defective units from unsatisfied customers.
I think Nokia will not get hurt from returned phones. In fact, they will have the benefit of immediately finding out what the problem is and they will be able to fix this immediately if they get all of our defective Nokia E5-00 units. They can (1) isolate the problem, (2) test as many phones as they want, (3) find out the problem and (4) make a happy customer.
These much claims is not tolerable. This is degrading Nokia. I believe Nokia has seen much already, and I am hoping that by the time they read my post, it would be the last.
And the next reply to this thread would be a happy customer with a newly replaced, non-defective, Nokia device.
Thanks,
Eljun Pacomios.

C3-01 won't start after charging

I'm so angry right now but I will try and be cool about this!
I bought C3-01 mobile phone about four months ago and it is already causing me problems.
The mobile phone simply won’t start after charging. Last time i charged it, it miraculously came to life only, and only after annoying me for about hour and a half. Now I fear it is completely dead!
Battery was not completely empty so the phone should still start even if the wall socket is broken. Which is not, wall socket works perfectly.
Nothing helps! I tried removing the battery and then restart. Removing the battery then removing the sim card, memory card and that piece of “advanced technology” simply won’t start!
I didn’t buy my new phone so that I can use my old Motorola mobile, which btw., still works after 4 years of intense usage.
I will never buy Nokia again!

Hi,
Sorry to hear that your phone is not starting after charging.
I would suggest one more thing, which maybe helps. If you have another battery, please try.
If not, i would recommend to visit Nokia Care Point in your area.
To find your nearest Nokia Care Point, visit http://www.nokia.com/support and select the Repair page.

Mac Mini won't start after installing OS X 10.6.3

My Mac Mini won't start after installing Mac OS X Snow Leopard 10.6.3. When I turn it on, the Apple logo appears and the initialization line starts to fill, but it suddenly stops. It does that again and stops at the same point, but this time it shuts down. What should I do?

If you are coming from 10.5.8, hopefully you backed up your important data first. Your mini will need at minimum, 1 GB of RAM to install Snow Leopard and at least 5 GB of storage remaining on your boot drive.
I treat 10.6.3 as a fresh, full install over a 10.5.8 system. That means I choose Disk Utility from the Installer's menu and repartition the boot drive as a single partition, Mac OS X Extended (Journaled) format, and use the GUID partition scheme from the options button. At this point, while still in Disk Utility, I would verify the drive under First Aid.
Then I turn the installer loose, and reboot into a working 10.6.3 system, ready for the software updates that take the machine to 10.6.8.
So, following the above guidelines, reinstall 10.6.3.

Hi All,

Exe in "target" as shown in the following picture, then press "Ok" 3- Open Firefox, and then choose "options" from the list of "tools" 4- Select the tab "general", and in the list "when Firefox starts" then select "show my homepage" and in the box "homepage" then enter any other link and then press "OK"
