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.

Installed new RAM now computer wont start up

I just installed 2GB of RAM in my iMac and removed the 512mb card it had originally.when i pressed the power button it beeps fast a few time then the fan starts working really fast. The screen doesnt turn on only the sleep light blinks as the fan runs. I replaced one of the new cards with the original 512mb card and it starts but when i check the memory the slot where the new 1GB card appears "empty" why could this be? did i install incorrectly?

When you install new RAM you have to push much harder than you think you should. You won't damage the RAM, but you have t give a mighty push to seat it, make sure you hear a click.

New ram - computer does not start up

Hi all,
I have a first gen iMac G5 (1.8 Ghz, 250 GB Hard drive, 1 G Ram). This RAM was installed:
DIMM0/J4000:
Size: 1 GB
Type: DDR SDRAM
Speed: PC2700U-25330
Status: OK
I wanted to upgrade to 2 GB, so I checked around, everywhere it says I should have PC3200 RAM sticks, even on the Apple website. Same at the store (a kind of mall specializing in Apple stuff), they sold me 2 GB of DDR SDRAM PC3200. When I installed them, the computer would start up but get stuck on the little gear wheel, until the screen went gray and a message appeared in 4 languages saying that I have to restart the computer.
So then I put the old RAM stick back in, but same thing happens - computer would start up, get stuck on the little gear wheel, until the screen went gray and a message appeared in 4 languages saying that I have to restart the computer.
Any ideas what I could do? Or did I kill the computer for good?
Any help is much appreciated.

Hi again,
so, after a bit of struggle (mainly with the hard drive casing), I managed to switch out the hard drive for a new one and installed the new ram. Everything seems to work fine so far. Only difference so far is that the fans don't seem to come nearly as much as before. Things seem warm, but not worrisome hot, so I wanted to check if these temps are ok or if I need to be concerned:
HD 52C/126F
CPU 65C/153F
Hard Drive 49C/121F
Both Disk Utility and Disk Warrior report no problems.
If these temps are too high, how can I rev up the fans a bit?
Thanks for the help!

4 hrs later - Computer shut down after installing new RAM (mid 2007 Imac)

Mid 2007 imac and I installed new Ram. It worked for 4 hrs then the Imac shutdown. The pressed power button but no power. Unplugged and replugged the power cord and 3 beeps sounded. I am wondering if it worked for 4 hrs or so, then why did it would it fail 4 hrs later?
I am running the correct ram because in system profiler under memory - it said that everything was ok.
Any ideas?

or maybe the back tray wasn't tight enough?
I re-installed it now and so far so good.... I pressed tight and in an upwards motion. We'll see what happens

Computer wont start. three beeps in a row

Re: Brand new Pavilion 13 wont start

My computer wont start. What do I do? Besides reading instuctions on how to ask questions.
Also I tried using the chat but my computer was not mentioned when I typed its code which is why I tried this.
Horrible horrible service. Imagine buying a brand new computer that refuses to start up and several days later after asking for help and instuctions on what to do next...you receive guidelines on how to ask questions.
Thanks Hewlett Packard! Anything else I can do? Any suggestions on how to go out of my way for a faulty product? Would you like me to bend over now?

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.

Mac crashes regularly after installing new RAM

My laptop crashes at least once a day ever since installing new RAM. It seems to be triggered by quitting programs, usually Firefox, Logic or Spotify. There was nothing else connected to the Mac that brought about the latest crash but I do use an Mbox 2 on a regular basis.
Below is the last crash report and also the RAM profile. It's Kingston brand if that means anything.

It's almost impossible to trace back the panic report to a specific cause, but it's highly suspicious that you started experiencing problems after installing new RAM.
It's also strange that your RAM has no stated VendorID, Part Number or Serial Number.
I would return this memory poste haste.
Alternatively, if the DIMMs are from Kingston's ValueRAM range, just dump them in the garbage because that's where they belong. While you're there, look for any other RAM that someone else has thrown away - chances are its ValueRAM, too (hint: I have never seen a single ValueRAM DIMM work in any of my systems, so I avoid them like the plague - shame, since Kingston used to have such a good reputation).

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.

Checking & installing new RAM

Hi,
I have a Pavilion dv7 product number VG420AV notebook with 4 GB DDR3 system memory (2 DIMM).
I am wanting to upgrade the memory to 8 GB.
Hp told me to buy a 4GB, 1600Mhz, PC3-12800 memory module (SHARED).
I am not sure if I need one stick or two.
How do I check to see if I have an avilable slot to install new RAM ,& how do I install new RAM in my notebook?
Thanks fo the help.

That is a dv7t-3100 model. 2 ways to find out about the RAM. 1. Download and install CPU-Z and look at the memory tab; or, 2. Just pull the back cover off and look.
Here is the Service Manual:
Manual
Page 4-17
And you do say you have 2 DIMM(s) which is all the slots available so to upgrade you are going to have to remove and replace existing memory.
