Can PSU and or power spike damage mobo?
Can PSU and or power spike damage mobo? If so, how do you find out if it was PSU?
This computer's previous mobo worked for about 3 months then died. The new one, MSI KT6 Delta-L (MS-6590 v2.0) motherboard worked today then rebooted continuously (well it sounded like it) in quick succession, over and over. Please see previous post by me about 20 mins ago.

Could a bad plug or PSU be frying my computer ? Thanks.
I have Firsthand Witnessed 5 Brand new (Q-TEC 550 Gold) PSU's Destroy everything in the Case, CPU, VGA Card, Motherboard, and Both Memory Modules, and out of the 5 PSU's that Blew, 3 of them Actually Caught Fire ....If you have ANY Doubt about the Health of your PSU, Do NOT use the System until the PSU has been Checked, or Better yet, Purchase a New Quality Unit...........Sean REILLY875

I have a iPhone 3GS and the power connection prongs are damaged and it won't charge or sync. Is there any way to repair? Or, at least is there a way to charge so I can write down phone numbers and othe rinformation. My power charge is totally out right now.
If it will not turn on - you have zero chance of getting anything off the phone.

Are Laptops inherently Safe from Power Spikes and Failures?
Are laptops like the iBook or MacBook series inherently safe from power spikes and short power failures due to the fact that they essentially are running on battery power all the time anyway? Should one use a UPS for a laptop?
I have my iBook connected through a surge protector, but it is not connected to a UPS as well. Should it be? The reason I ask is that today, there was one of these split second power failures. I was not at the computer at the time, but noticed that the printer recycled. When I went to my iBook it was dead. I couldn't start it by pushing on the start button either with the power cord plugged or unplugged. I thought it had gotten zapped some how. But how?
Just for grins, I removed the battery and plugged in the power cord. It started up fine. I powered down, place the battery back in and it started fine on the battery as well. What do you suppose was going on here?
-BillBill,
No, it isn't. You can get power spikes through the AC power cord, the modem, the ethernet port, or any peripheral connected to the computer. A power conditioning UPS is your best bet for protecting it. Make sure that all other connections are also routed through the UPS, too.
It's likely that what happened was that the clamping voltage for the surge protector was too high/too slow to completely prevent a surge into your laptop - either on power down or on main power restoration. It wasn't enough to fry it, but was enough to trigger an overload. Removing the battery allowed it to reset and operate normally.
Since I live in Lightning Central every monsoon season, I can tell you from experience that it is far less expensive to replace a burnt out power-conditioning UPS (or UPS batteries) every few years than it is to replace a boatload of cheap surge protectors or non power-conditioning UPSes and attached hardware.

After reading and resetting everything with Keyboard I still get blank white screen on 2nd? page of boot. The only way I can boot to Mavericks is unplug power cord, push and hold power button while plugging power cord in. Fans run at full speed, machine boots then runs normal except the dvdrw will not . The mid 2011 IMAC had the same problem with LION. I changed hard drives, formatted, and installed a clean install of latest os x mavericks. Any help would be greatly appreciated.

Use the uninstaller provided with the Sophos software. You can uninstall CUDA via the preference pane. Be sure you remove the com.nvidia.CUDA extension which is located in the /System/Library/Extensions/ folder. Not sure if Fan Control has an uninstaller so you will have to do it manually:
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
1. AppZapper
2. AppDelete
3. Automaton
4. Hazel
5. AppCleaner
6. CleanApp
7. iTrash
8. Amnesia
9. Uninstaller
10. Spring Cleaning
For more information visit The XLab FAQs and read the FAQ on removing software.
Be sure to remove your two Login Items. Finally do this:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless. -
I have an iMac G4 PowerPC with OS 10.5.? After deleting 17G of music files to make room on the 74G drive, The iPhoto and iWeb updates seemed to load okay, but the OS 10.5.8 update failed - message opened said the computer encountered an error and must shut down. Now I get the blue screen. Startup with 'V' pressed shows multiple lines saying: error-can't find IntelCPU Power Manager. What now?? I reset PRAM, I think.....?????
I am concerned that you might have applied a system updated intended for an Intel iMac, while you have a PPC (non-Intel) iMac. Your PPC OS should not be looking for an "IntelCPU Power Manager."
Have you tried booting from the 10.5 install DVD/CD and repairing the hard drive, plus repairing permissions?
If you done the repairs mentioned above, and your problem still persists, you can also try doing a safe boot. (see http://support.apple.com/kb/HT1455 ) Then, if none of these things worked, if I were in your shoes (it's hard to diagnose these things without being there in person) I would first check that there is adequate disk space, then I would boot from the 10.5 DVD/CD install disk and reinstall the operating system. There is an option to do an archive and install preserving user files/settings, that would be the option you want, as it will save your files but install a new OS. Make sure you have a good backup of your files first. If you do not have one, use "target mode" to copy all your files before embarking on an new OS install. Assuming that you do succeed with this install, then use Software Update to get the right updates for your iMac. -
my iphone fell on the floor and the power botton wont work and also the screen went black i already tried to reset it throun itunes but the phone did not connect and i dont know what to do

TS1367 I have a new iMac and can't get it to turn? Can't find a power button?
Have new iMac and it won't start up. Can't find a power button?
Try to perform a HARD RESET on the printer first. Unplug the power cord from the printer, and leave it out for 30 seconds. Plug it back in, see if it aligns and finishes the job.
After alignment, try to print a test page from the printer or make a copy. This job is to make sure that the HARDWARE of the printer is working correctly.

Hi! I bought my iPhone from USA and the power button doesn't work. I have warranty. I will come to UK soon. I wanna learn; can i benefit my warranty in UK?
The warranty is not and has never been International. Warranty and support are only valid in the country of origin. The only exception is for devices sold in the EU where the EU is treated as one country for warranty and support purposes.

My Ipod nano touch is not charging, not showing in my PC or laptop. Last I saw an apple icon and low battery signal. There after the screen is black and no power not taking AC or PC charge. What Can I do?
If the Reset didn't work, you'll need to do a Restore.
From iTunes, select the iPad and then select the Summary tab. Follow directions for Restore. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finished, you will be asked if you wish the contents of iTunes to be copied to the iPad. -
I got my iPhone 5 a little over a year ago, and my power button recently quit working. Since ive had it for over a year, can i still get it fixed or replaced?
Wow that is so unlucky. If I was you I would try talking to someone at the Apple Store, explain your situation and don't be shy to shed a tear or too. Its just a shame 3 weeks after your phone getting hardware problems. I know people will say, oh buy Apple Care but I feel ya and I know adding that extra money in the beginning feels pointless and expensive.
Worst case scenarion like I said you will have to pay Apple 269 for them to swap phones. Or if you have any nerd friends have them fix it for you. Its a tedious repair the way the power button has some weird hinge that needs to snap on and ribbons are so thin. I do not advise for you to attempt to fix your self unless you don't care if you break it completely.
Alternatively you could just turn on Assisitive touch on accessibility and use that. That way you wont need to pay anything to fix your phone and wont need to take it apart either. -
So I forgot the password to my phone and my power button just broke so I can't dfu mode or anything. Please help!

Havig upgraded to OS X lion I have lost access to Power PC documents. Will iWork be able to open them?
Documents are not "PowerPC" or "Intel" or even "AMD"
Depending on what file format the documents are, you may find various programs that can open and edit them. But, without knowing what kind of documents they are, I'd have to guess if any of the iWork suite could open them. Pages can open Word .doc and .docx files. Numbers can open Excel .xls and .xlsx files. Keynote can open Powerpoint .ppt .pptx files. I don't know if they can open Appleworks documents, but I think I've seen positive remarks about that. -
ok my iphone 3g touch screen is not responding, i can recieve calls and it can charge and connect to itunes, but i cannot go any further than using the home button or the power button, it is only the slide feature and touch feature that has become non existent. Also, i have a f'ew cracks in my screen for a while now and it was running smoothly up until saturday when i sat on it applying large amounts of pressure to the phone screen. Is there a way i can fix this myself without having to recover my phone to factory settings or wasting 50 bucks to get it fixed??

You can use the adaptor that came with your device. They work in the UK. You will need a wall outlet plug adaptor, however. You can buy them at most AAA travel outlets, computer stores, or buy Apple's World Travel Kit.
