HP Pavilion p6774y won't start, 1 short beep 1 long beep

My HP Pavilion p6774y now makes one short beep followed by one long beep repeatedly when I turn the power on. Nothing comes up on the screen. I've taken the RAM out, switched them around, cleaned out all of the fans including the one in the power supply, taken the video card out, unhooked all extra things like monitor, mouse etc, no luck..
It is a HP Pavilion p6774y PC

6gb DDR3 memory
1 TB harddrive
Windows 7 OS
ATI Radeon HD 5750 Graphics Card

Won't start up - 3 long beeps and 1 short beep repeated

As I was watching Netflix, the display went crazy and displayed horizontal lines and the computer froze.
I held the power switch down to shut it off.
After restarting, seemed to work fine for a few minutes, then same thing happened.
Reset again. Seemed to start up fine (heard the chime and the hard drive going) but no display output.
Reset again. Got the start up chime, a white screen with horizontal lines, and I get 3 long beeps and 1 short beep repeatedly.
Any ideas?
Thanks for your help in advance.

The beeps you're hearing means the system has no usable memory. You can try reseating the memory or swapping for other known working memory (pain as it is to open the mini up). Otherwise, typically that means it's new logic board time. See this Apple article: http://support.apple.com/kb/HT1547

27" iMac 3.2 i7 won't start. Emits 3 'beeps', pause, repeats.

My 27" iMac 3.2 i7, 20GB RAM won't start. Emits 3 beeps, pause, 3 beeps, pause.

Here's a link to an Apple support page that describes the possible Startup tones.
Mac computers: About startup tones - Apple Support
The short answer is here. Looks like your RAM is bad.
1 tone, repeating every 5 seconds: This indicates no RAM is installed.
3 successive tones, a 5 second pause (repeating): This indicates RAM does not pass a data integrity check.
1 long tone while holding down the power button: Indicates an EFI ROM update is in progress on a computer manufactured before 2012.
3 long tones, 3 short tones, 3 long tones: Indicates EFI ROM corruption is detected and the computer is in EFI ROM recovery mode.

HP Pavilion Entertainment won't start just shows blue screen

HP Pavilion Entertainment won't start just shows blue screen. Sometimes says missing operating system after changing boot order. I have seen error message 303. This happened after I couldn't stop coolncheap popups so I saved everything to another computer and did a complete restore. When I was in the process of getting it back to working order I allowed updates recommended and optional and then everything started.

Also pressing F11 won't take me to recovery

PowerBook G4 - Won't Start Up - 3 Strange Beeps then just LED flashes and sudden death - black screen.

PowerBook G4 - Won't Start Up - 3 Strange Beeps then just LED flashes and sudden death - black screen.
Prior that the powerbook also couldn't start but I could see the Apple logo, so via fire-wire (holding T at start up) I backed up the hard disk.
Check via DiskToolPro the structure, defragmented. Via DiskWarrior rebuild the directory
and finally not been able to access the drive I reformatted the drive via fire-wire drive.
Re-started the powerbook holding C to boot up from DVD - nothing
Re-started again and it give me one long beep and black screen. An indication that my 1gig RAM is bad or gone (?) and the DVD is stuck inside.
Bought new one 1 gig, installed it and now I'm getting only three beeps.
I tried all, changed the slots several times and nothing.
I tried more as:
                         c -- to boot from CD (again while the DVD is still inside and I cannot get it out)
                         cmd-opt-p-r -- to Zap the PRAM,
                         cmd-opt-n-v -- to clear NV RAM,
                         cmd-opt-o-f -- to boot into open firmware … and nothing. The DVD is in and I have
                                                black screen with three beeps and flashing LED.
Do I have to replace the Logic Board?   (Anyone has a spare one ?)
But it is the faulty Logic board?
Could anyone help me out? Please.
I'm retired and I cannot afford a new laptop - and this powerbook was a great, great horse for me until that horrible set of three beeps.
Thank you in advance for any advice and help.

But it is the faulty Logic board?
There was a known issue with LBs in 15-inch PowerBooks with 1.5 and 1.67Ghz processors in which one RAM slot would fail. There once was a repair extension program that fixed the problem at no cost, but it is long-expired.
The problem with seeking a used logic board for these models is that so many had their boards replaced that it increases the chances of the boards in the used/pulled markets having the same problem you have now. The replacement program also came close to exhausting the supply of new boards,
If it turns out to be a bad LB and you can't find a replacement, consider how used computer pricing works: A used computer is worth hugely more in parts than if bought as a working unit. I.E, you can probably find a working PowerBook that will cost less than the logic bard alone. It also possible to find a used MacBook Pro for less that a replacement LB.
If you tell us your approximate geographic location, we can see what's available nearby. I'm also retired, and and visiting my wife's family this week so have even more time than usual to help you search.

My MacBook Pro won't start it just goes beep beep beep when I press the power button

My MacBook Pro won't start it just goes beep beep beep when I press the power button

Hi Csound1,
I haven't added any RAM my daughter was using the computer then it hung so powered it down then the beeping started. Do you know if there is a combination of buttons I can press when powering up that will put me in some kind of safe mode so that I can find out what's up, I tried pressing D when the beeping started but it didn't make a difference.

Power Mac G5 won't start up and is beeping

Dear friends,
This morning, my Power Mac G5 started to beep. When I try to restart it, it beeps some more and also makes a clicking sound like a metronome.
The computer won't start up anymore. At startup, it displays a grey screen with a little folder in the center that flashes a question mark and a finder icon.
What is wrong with my excellent computer, and how do I fix it?
Marnie

Marnie Glickman-
Could be a variety of things, but most likely your hard drive is not happy. The flashing question mark means that the system is trying to find a working disk with a valid system on it. Should be the hard drive. Isn't.
Launch from the install DVD of the latest OSX system you have. Under the Apple Menu should be the Disk Utility. Launch it and try repairing your hard drive and see if that does the trick.
If not we dig deeper into this excellent problem.

Won't start up, makes weird beep, power light flashes, and fan revs

I just tried to install new ram, but now it won't start up. I put the configuration back to what it was, but still not starting up. It makes a different beep then the fan gets really load, and the blue light flashes slowly...
ahhhh... did I break it?

Hi don rumsfeld-
Greetings and welcome to the Apple boards

My guess is that the RAM was either not installed properly or not seated firmly. This may be helpful: Memory (DIMMs)

My iMac won't start...just beeps. What do I do now?

My iMac won't start up anymore. When I hold down the power button for 3 seconds and then let go al it does is beeps 3 times and then pauses for about 4-5 sec. , the 3 beeps and pause, and so on. Everything was working fine. I shut down the computer and now can't geitback on. Is it ruined?

Three beeps at startup indicates bad or loose RAM.
You can look up videos on how to replace RAM on your model Mac, at YouTube, or Other World Computing.

Can anyone help me with my Imac that won't start up and continuously beeps

When I turn on my Imac it chimes then goes to a grey screen and starts a loud continuous beeping sound. It's only 6 months old - I put new memory in when I first got it and up until now there was no problem at all. Can anyone help me get it up and running again?
Thanks so much.

Thanks everyone for your kind advice. Reinstalled the RAM - still no difference - what I am getting is the start up chime, a grey screen, and then three loud beeps in a row then a pause then three beeps again and so on.
Tried starting up holding down D key - no joy. Any other suggestions gratefully received.
Thanks again.

Power Mac G5 - Won't start up with the beep noise.

Hi all,
I am wondering if someone can help me with my problem. I've just gone to turn on my G5 after dusting out the inside (i unplugged the power supply and then lightly dusted the inside) and now it won't turn on.
The power light comes on, but there is no beep, and the fans start, but they gradually get louder. The white power light then flashes once in a while
Can anyone offer any help please?
thanks
Mark

Well - as long as you have pressed the button firmly once, that should be it.
I did wonder if you had disturbed the RAM while you were rummaging inside - is there a pattern to the flashes of the white power light, as described at the bottom of the page here
http://docs.info.apple.com/article.html?artnum=302527
If not, as the mains power has been disconnected, it's just possible that the internal back-up battery may need replacing

Pavilion dv6700 won't start

I'm having a problem with my laptop that I've never had before. As it says in the title, I have an HP Pavilion dv6700. I was using it today, for nothing different than I usually do (an MMO, internet, and msn), and it randomly turned off. I blinked and tried to turn it back on. All the lights turned on, then it shut off again. So I thought it might have overheated and took out the battery, and waited until it was cooled off to turn it back on. For a bit it stayed on, told me to scan during startup, which I agreed to. In the middle of scan it shut off again. Now it won't even get that far, it just turns on for a split second and then turns off.
I looked at the help section, but it didn't seem to help me. It referred to lights blinking, and none of my lights are blinking at all. They all light up as if it's going to start, then all die at once. No deviation from that. Is there anything I can possibly do?

Hi Kivri,
Please try to click this link and look for the specific type of problem that your notebook is having.

Hp pavilion dv5000 won't start up anymore

My notebook pavilion dv5000 with windows xp is not starting up. The battery has been dead for a while now but itwalkways worked fine with the power plug in. After a while, the computer would unexpectantly shut down after a few minutes. Now, I can not get the computer to completely turn on. I am prompted with the black screen informing me that "windows has not started successfully due to a recent software or hardware change.". It gives me the options to start with safe mode or windows normally. I have tried every option multiple times. The closest I can get is choosing to start windows normally. Theblack windows xp screen loads and then the computer dies again andTatars the entire process again. What can I do?

Try using this document to perform a hard reset on the notebook: http://goo.gl/C9BLD
If that does not work for you, just let me know and i'll see what else I can find for you.

HP Pavilion Desktop: Won't Start/Tower Lights Up

I have an HP Pavilion p6130yv running Windows Vista.
For several weeks, occasionally while working, my monitor would suddenly turn white, preventing me from interacting at all with the interface (no mouse arrow, no response from Ctrl+Alt+Delete, no auditory response whatsoever). Sometimes, before it went white as described, my screen would flick every half minute or so. I could easily get rid of the white screen by restarting the computer. No problems for several days until it happened again. Rinse and repeat.
I left my apartment for two weeks to visit my family, and I return to find that now the computer will not boot. The light on the tower comes on, there's the familiar whir and click, but the monitor does not show any activity, just a blank screen. Most of the time... I find that, if I leave it off for awhile, the monitor will display the startup screen and begin to boot when I turn on the computer, but then it goes blank again, always after reaching the Microsoft loading bar (see the image at bottom of this post).
It does this before I can enter startup repair or safe mode as well. Also, when this happens, the tower will usually light up and power down several times before actually showing anything on screen.
That's the breadth and depth of it. Thank-you very much in advance.
P.S. There was a power outage several weeks ago, but I do have it connected to a surge protector. Could it be a virus?
