Computer wont start. Fan comes on

Fan runs really fast. I used it 3 days ago and did the shut down after update. It hasnt worked since. Grrrr I hope it gets better

Recommendation for your consideration:
Sounds like a thermal issue: i.e. Overheating of CPU/GPU and/or harddrive.
Do you have any of the free temp. monitoring s/w? Pse advise.
The fan running really fast also tends to indicate thermal problems...but after 3 days?
Have 3 mo. old 17" MBP and fan only has accelerated less than half a dozen times.
Let 'er rip and...
cheers.

MSI Z87-G45 Gaming- computer wont start after bios update

Hello!
I just updated my bios to 1.6 --> computer wont start now but the fans are spinning, and the power led are black...
I took out the cmos battery for 30 min and shortened the JBAT1..
Can someone help me?

Well, as the G45 does not offer a backup bios your board seems to be bricked. You can try the recovery tips here: https://forum-en.msi.com/index.php?topic=174985.0
If no help rma it.

My computer wont start!

My computer wont start and i dont know why!

If a SMC reset fails to bring life to the MBP, make an appointment at an Apple store genius bar for a free diagnosis.

I assume you have a functioning power adapter attached to your MBP.
Ciao.

Computer wont start up

So today I went to start working on my LR and FCPX projects and when I got to the office for no reason at all my computer wont start up.
I've tried holding the "shift", "command" & "V" key from what I read to do, and now I get a black screen which pretty much said what the grey screen said.
This is the strangest thing.

According to your profile your Mac has v10.8 installed.
Startup your Mac while holding down the Command + R keys so you can access the built in utilities in OS X Recovery
From there you can repair the startup disk if necessary or restore OS X.
Hopefully you had all your important files backed up in advance just in case.

Computer wont start in any mode

my windows xp computer was just working this past week till i restarted it and it said that i needed to download a antivirus and i have one it just wont open up in safe mode or the regular mode so now the computer wont start at all and now i was wondering if i could get a new computer tower and plug in my netgear wireless G router into this new computer tower and have internet and everything

plugging in a new tower should work. its like a whole new computer with the same screen and stuff as before. mine just got a bad virus and it wont start either. might have to do the same thing.

i upgraded to yosemite last week, now my computer wont start. it stops at white screen with apple logo. what do i do?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

Hello!
I tried to write a full system specifikation.
Hope i got everything in it.
mm not yet read Moan Guide give memory spec, PSU +12V ampere stats...
and remaining hardware installed in your system.
ensure power cable from PSU to VGA is plugged in.
if no change try with better and decent PSU which can handle your newest VGA, with high amperes on +12V

Computer Wont Start Up Completley

Hope Im in the right forum here....... I turn on the computer, and the desktop comes up, but the little rainbow circle keeps spinning and spinning and spinning and spinning and......NOTHING else happens! No icons appear on the desktop, everything is just frozen. I tried disconnecting all peripherals but that didnt help either. Help! Please (I used Mac G5 dual)

rolesh79:
Before you attempt to re-install:
Repair Disk Permissions
While booted from your internal HDD
Go to (Applications > Utilities > Disk Utility.
Select your HDD (manufacturer ID) in left column and First Aid in main column.
Click Repair Disk Permissions at bottom left.
If that does not help go to Home > Library > Preferences
locate com.apple.iMovie.plist
Select and drag to the desktop
Restart and test.
Do the same for iDVD.
If removing the .plist does not help please report back.
Good luck.

Installed new ram, computer wont start up

I installed 1gb of hynix ram. I tried setting it in different ways, but each time when i start up the computer it doesnt even get to the chime sound, the screen doesnt come on, my fan just runs loud and fast and nothing happens, but it starts up fine with out the ram. is there any hope of installing this ram?

Generally if your computer won't start up after you have installed new RAM, either you have purchased the wrong type of RAM, or it is a bad module.
As long as you are able to start up normally after removing the new RAM, and it is supported, it might just be a bad module. Contact Hynix to arrange for a replacement.

HELP !! Computer wont start after i change from 133 to 166 on my FSB

Hi...
I have a K7N2G. I changed the my fsb from 133 to 166. Afterward, I have not been able to start or boot my computer (my fans are on, but monitor is not geting any output).
Thank you and greatly appreciated to anyone that can help me.
Yoge

Hahaha yoge i fell yr pain man cos i did the same thing 3 weeks ago!! I just got my computer back from the shop on Tuesday. What happened was i managed to kill some chip on the mother board and the chip had to be replaced.
This is the story:
Amd XP 2400+,
MSI K7n2g-ilsr
400watt coolermaster
USING THE ONBOARD VGA!!!! (im a dumb F**K, i noe this now)
dual channel 2*256mb sticks (transcend & Kingston value)
I had just installed the latest bios so the kinston is
supported.
High performance settings
FSB/DRAM Ratio 1:1
The only values i had for the FSB were 100, 133 & 166Mhz so i put to 166, i pressed F10 to save and then black screen.
The power was on, the monitor was on, but the hard drive shut down shuted down. So i took a look at the back to check the 4 LED's, 1,3,4 were RED and 2 was GREEN which meant the memory module was damaged, or so it said in the manual.
Apparantly ur not supposed to overclock with the onboard VGA and it even says that in the manual (i must have skipped pass that, duh)
So yoge your gonna have to take ur computer back to the shop to get it fixed sorry to say.
I cost me $35 AUD + $55 for service charge but they oly charged me $35 for the sevice fee cos i am a regular customer.
Also when i got back my computer this week, i opened up the case and do u guys know what i found, a GeForce4 440MX graphic card!!! They gave me a free graphic card!! Woohoo
Well now my computer runs fine with no problems yet and my cpu runs at 25 degrees where as before it ran at 51 degrees.

HELPPP! COMPUTER WONT START!

so last night I went to put something in my trash on my black macbook and it froze so I held down the start button then my comptuer made a ticking noise then it stopped doing that so when I turn on my computer it makes the noise that supposed to come on then the screen stays blue and this a file with a question mark appears and flashes and that's it it doesn't go any farther! What should I do!

My MacBook is also showing a blank screen with the folder with the question mark on it - how do you get it off?! My computer doesn't load! It's not even that old! If it is a drive crash, how much do they cost to replace?

Computer wont start after apple logo shows up..

I have a friend who owns a MBP 13 Late 2012, and suddenly he explains computer after he shut it down, the gray screen shows up and apple logo too, but never enter to the OS.
I have had this problem with a 2009 iMac in the past and they told me it was a problem of humidity and or dust, and so they had to change the Motherboard.
Have any one experienced this ?
I even did the PRam reset several times with no luck, actuallu It wanted to start (get into the OS) but MBP kept with little spinning circle.
Any thoughts?

So I received the MBP, and did the Command R to get to recovery mode, and after the World spinning, I got this Message: www.apple.com/support and then -5010F ... (image 1)
Power it off and reboot it with OPTION key, and selected Macintosh, and after that the Apple logo shows up with the little circle spinning infinitely.
What do you think? Doesnt go any further than this: (image 2)
