G5 cuts out randomly after installling new RAM

Hi all,
I have a Powermac G5 (1.8GHZ) and have just installed some new RAM taking it up to 6Gb. It worked fine for a couple of weeks and then myseriously shut down one day. When I tried to re-boot it turned on OK, chimed but then cut out a few seconds later. Thinking this would be the RAM I took it all out and restarted with my original setup. Everything worked fine... So then I thought I would add in the new ram gradually to see if I could find out which card wasnt working; I ended up adding the whole lot and it worked just fine.
Then all was fine for another couple of weeks and exactly the same thing happened. This time the computer only turned on properly once the old RAM was in the first two slots. Then I added the new RAM and all is fine again. Is this a problem with the RAM as it does seem to work..up to a point.... Any ideas??
thanks for your help!
Jay

Perhaps it's time for this......
Try running your Apple Hardware Test . It's not perfect, but may flag something.

  • 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).

  • Macbook dead after installing new ram (1gb in each slot)

    After upgrading my MB ram to 2gb (1gb each slot) my MB would not start, no lights or action. I replaced the old ram and still nothing. I then went to a genius bar and they tested it out and even replaced the ram with ones they had and still nothing. I was then told that the logic board was dead. Has anyone had this problem? Since it is out of warranty I have to pay $280 to have them repair it which is a flat fee and they will fix it no matter what is wrong which I find is better then some rates I have seen posted online for $600 just for the logic board itself.
    My MB is the 1.83, could 2gb be too much? I have had the MB since July 2006 and recently had battery problems before I replaced the ram. Could this have fried the logic board?
    having a mac nightmare right now!

    Improperly seated RAM is fairly common... but I haven't seen many comments about inserting RAM actually damaging the logic board... but you do have to use quite a bit of force to get them in there. The good thing is the price that they are charging you for the repair... as you mentioned, I've never seen them charge that little for replacing a logic board. I wonder if that is something new.

  • The audio on my iPhone 4s cut out randomly; I have to unplug and replug headphones to get it back. How can I fix this?

    For the last year I have been unable to use my iPhone speakers because of some bug. I can play music and audio through headphones, but that's it. And just today even the headphones became spotty. I'll play a song (through iTunes) for a while, then the audio will just cut out. I can get it back by unplugging and replugging the headphones (sometimes multiple times) but that fix doesn't last long; usually within a few minutes (if not much sooner) the music cuts out again.
    I really don't want to buy a new one because this one otherwise works fine. How can I fix this?

  • EXTERNAL HARD DRIVE CUTS OUT RANDOMLY

    Forum,
    While in working in FCP, my external hard drive (G-Raid 2) keeps cutting out - 3 times in the past few hours.
    I think it's a bad connection, but I'm not sure.
    Any tips?
    Thank you,
    Trey

    Check the cable connections and power supply.
    Could also be drives going bad. Does it only happen undwer certain circumstance (when you step away and the computer sleeps, during long renders, etc.?) Or is random?

  • Laptop freezes after installing new ram card.

    Hi,
    i recently upgraded my ram card on my toshiba c650d laptop. after installing the ram card the laptop began to freeze while in the desktop and then it could be resumed when Alt+Ctrl+Del was pressed.
    and the laptop wouldn't wake from the sleep mode.... 
    please help me this is urgent...as for im leaving my home country for studies.
    thanks for the help in advance
    Malith Ratnayake.

    Hello Malith Ratnayake,
    After changing the old RAM by the new one, this issue occurs?
    If the issue doesn’t occur when you change back to use old ram, I think it is the RAM hardware issue.
    Please contact the hardware manufacturer for better support.
    Best regards,

  • After installing new RAM module macbook will not wake without re-start

    Im having a little problem with my macbook. It operates normally and the new RAM appears to function as normal except when the computer is in sleep mode, it appears to sleep as normal but when the lid is raised or the power button depressed to wake the system up it will not do so without a full re-start. Any help is much appreciated. I have tried re-setting the PRAM and performing the usual maintenance functions from OnyX.
    Thank you.

    Did replacing the RAM fix the problem? I am also experiencing the same issue. The RAM works great when the computer is running but occasionally I cannot get the computer out of sleep mode and must reset the entire machine. Is the only cause of this a bad stick of RAM?

  • [Other 865 Series] 865GM2-LS - power cuts out immediately after turning on.

    I wonder if anyone could help me, as I am a bit out of ideas. I've done a search on this forum, and though there are a few people similar problems, there does not seem to be an answer.
    I have basically tried to build a PC from scratch for the first time (the specs are below) I'm pretty sure it is all connected up correctly, yet when I turn it on, the lights come on and the fan turns for a fraction of a second and then the power cuts out.
    If I then attempt to turn it on again I get no power at all. If I disconnect/reconnect the power supply from the motherboard and try again I get the lights and fan again for a split second.
    I have checked and double check the connections, reset the CMOS by moving the jumper as in the manual, and I am pretty much out of ideas. These are completely new components, no s/w on the HD at all etc. I've checked the pins for the ATX 20-Pin and ATX 12V and they seem OK. One thing I can think of is there is a power connecter next to the one for the CPU fan for the system fan. I do not have this connected to anything as the fan that comes with the case connects directly to the PSU. Do I need a system fan as well or is this an either or thing?

    My fault, wasn't thinking. I meant to type "try running the motherboard outside of the case".
    You need to try a better PSU than your current one so the one from your old computer may be no good. Post its +3.3V +5V +12V rail amp values please.
    Also try disconnecting all but the essential hardware need to run so unplug hard drive, floppy etc. The problem looks like the power supply to me so buy or borrow a decent one with 20-24A minimum on the +12V rail. If you need help finding a power supply just ask.
    That would be very much appreciated, I've had a look around the usual web suppliers and they don't seem to want to provide that kind of information for their PSUs.
    The old PSU doesn't seem to have the info printed on it, but it is quite old, so I suppose it's unlikely it's going to be much better than the new one.
    Will try running it outside from the case. I take it this is in case the thing I have mounted it to is shorting it? If this is the case, is there a trick to ensuring against this?

    make sure no OC settings are used and set DDR voltage to 2.60-2.70 to get sys stable and work down as needed.
    How do I do this? Pretty sure I have no OC settings as I have left all jumpers alone apart from the CMOS one. How would I set the DDR voltage?

    Just installed 1 MB of new ram. Everything appears to work with one very annoying problem that never existed prior to installation of ram. The problem is that the window moves slightly with any movement of the mouse. Not a great deal but enough to hide the menu at top of screen. I ran an Apple Hardware Test and all hardware passed. I changed the mouse but no cure. This happens with nothing running so I assume it is not software. It doesn't appear to affect the operation but it tends to make one sea sick with the up and down and side to side motion anytime the mouse is moved.
    Shure would appreciate any help with this.

  • 865 GVM3-V restarts before booting OS after adding new RAM

    I had RAM in only one DIMM slot which is TwinMos 512MB 400MHz (CL3).
    I wanted some performance upgrade. I bought a new DDR RAM, Transcend 400 MHz 512 (CL3) and installed into the second DIMM slot of my MainBoard. After the moment powering on CPU restarts continuously just showing in the RAM size as 1GB (1024....), then showing the Primary IDE master disk and slave, then showing press del to enter setup, F8 to select boot disk and then reboots. Again it continues same. If I select del it does not enter into BIOS setup, simply reboots. It never goes upto booting the OS.
    As I thought RAM might not have been fit correctly into the slot I unplugged them and then reinstalled. No result, restart continues.
    I assumed if new RAM is damaged one. So I connected both of the RAMs seperately for test. They works just fine as single. But when I connect them both something goes wrong and it restarts..
    I thought if the problem was with GRUB (I don't see such possibilites actually) I made windows partition as active so that it can boot into Windows XP directly without going through GRUB. No positive result, restart continues.
    Then I guessed if there is a problem with combination of DDR RAMs of different manufacturers. I tested them(the two RAMs) attaching into another PC(MainBoard: Intel D101GGC) together to check if problem is the combination. There was no problem shown by that PC, boots and works just fine.
    I'm in headache with this kind of hardware problem as I have some other tasks to do still this is giving me pain. Why shouldn't it work in my PC!
    Any kind of help is greatly appreciated.

    Yes, that's pretty weak for modern machines. Go for better one.
    Go for quality PSU single rail with 30A[or more] @ +12V

  • 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

  • MacBook won't even turn on after installing new ram

    I am using the 2010 MacBook (white 13 inch) I bought ram (two 2gb modules) and was going to install it. I removed my Original ram, but accidentally powered it on it the process (no ram was inside). I got a longed beep. I held the power button and shut it off. I then put the ram back in and it won't turn on. I don't hear any parts moving, no power, nothing. Yes I put the ram in right, an it's tight as can be. Its pushed in well. Help! I never put the new ram in!

    The new ram doesn't fit. The laptop won't turn on with old ram. It worked before I removed it now it doesn't. It's I'm there tight so don't tell me to put it in with pressure because I did

  • PB cuts out randomly

    My powerbook 15inch is cutting out on me, i start up the computer it seems fine at first then the power goes this seems too happen whether it is plugged into the wall or running off battery? Any ideas?
    Powerbook G4 15 inch   Mac OS X (10.4.7)  

    Welcome to the Apple discussions.
    You might run the Apple hardware test to see if it points anything out. Insert the first OS X DVD that came with your system (it will say AHT Version x.x in small print on the DVD), reboot holding the option key down, choose Apple hardware test, and follow directions.
    You might try resetting the Power Management Unit (PMU) also. Follow directions athttp://docs.info.apple.com/article.html?artnum=14449

  • IPhone 6 Music cuts out randomly during songs

    My iPhone 6 has been doing this really weird thing where on certain songs the music will just cut out. The phone still says it's playing the song, but there is no sound coming from my phone. It does this regardless of if I use headphones or not.
    Like I said, it's only on certain songs, and it always stops at the same time during each song (I.e. one song will always stop when there's 43 seconds lefts, one song will always stop when there's 19 seconds left, etc). The songs play perfectly when I play them using iTunes on my computer, so it's not the song. I also tried removing all of my music from my phone and then putting it back on there, as well as a full restore. Nothing has worked.
    My iPhone is currently running on OS 8.1.3. If anyone could help me, I would be so grateful. Thanks in advance.

    aha. If you synch your phone it delete all music but next time if you delet it manually by phone it transfers the music and next sync it will delete all music again, right? When I have had that trouble I just have to disable iTunes match and delete the music manually if it's not do automatically. Then I could sync it and the music will load and remaining on the phone, also for further syncs.

  • CONNECTION CUT OFF MINUTES AFTER DOWNLOADING NEW ITUNES

    After downloading the "new and improved" download for Itunes, my connection was lost. I tried to reopen my connection many many times. Verizon Broadband didn't have any issues. My mother's computer worked fine--she still had access. I think something about the Itunes doesn't like my wireless router, or vice-versa. I had to delete the new Itunes program, and now I can get online again! I DON'T LIKE THIS NEW ITUNES! DOES ANYONE KNOW WHAT HAPPENED HERE????????

    Ok delete ichat and re-install.
    Put in your install disk 1(the disk that came with your mac) then after the disk has opened double click on "Optional installs" then double click on the "Optional installs.mpkg".
    Then when you get to "Custom install......." click on the triangle by appications and then tick iChat and then continue with the install.
    When done download and install the 10.5.5 combo to bring iChat back up to date.
