Satellite C655-S5041 won't boot with new RAM (8GB)

I recently bought some Ram from Newegg which can be found here. I installed the aforementioned Ram into my laptop following the correct method (unplug, remove battery, etc.) however when I booted my computer up I received a black screen with a blinking cursor that freezes after a few seconds shortly after the manufacturer's page is loaded.
I know for a fact that the Ram I bought is compatible with my laptop as I'm using one of the 2 sticks at the moment along with the original Ram from my laptop. Here's where I am really having issues though.
When I have just one stick of Ram I purchased installed without the original stick my computer fails to boot up also regardless of which slot the Rams in. I have tested the sticks I bought, and my computer will boot up with them, just not without the original stick that came with my computer which wouldn't be an issue except that a) there's only 2 slots, and b) my laptop can't have more than 8GB of Ram.
My BIOS is up to date (Ver1.6) and so long as I have my original stick of Ram installed my computer boots without any issues. Needless to say you can see why I'm in need of some help.
Any help would be greatly appreciated. If you need any other specifics regarding my computer or settings feel free to ask and I'll do what I can to find them out.

  • IMac G5 17" won't boot with new RAM

    I tried to install 2 GB RAM into an iMac G5 17" - the computer won't boot at all. The sticks are fine (DDR PC3200 - tried them in a different computer), I reset the PRAM, all to no avail. With the original 256 MB stick, it boots fine, but with the new sticks in either slot or together, all I get is a black screen, no tone, and the fan goes on high. The firmware is up to date. What next?

    I have a similar issue with my i5 since installing an additional 4GB (2x2GB) RAM from OWC. It runs fine normally, but if I ever need to reboot the iMac, it usually hangs at a black screen and never chimes. I have to pull the RAM, reset them and then it'll boot. I wonder if there is some timing tolerance problem with mixing RAM (with Apple's Samsung pair).
    This morning (after installing 10.6.6) it wouldn't come out of sleep and I had to pull the RAM again. That's actually the first time it wouldn't come out of sleep.

  • Satellite L30 10Y doesn't boot with new RAM modules

    Hi,
    just regged with this forum as I am having a memory upgrade problem.
    I have read through a few of the memory problems on here and all users say its a comaptible memory issue. I had Hynix 512MB RAM in my laptop and I purchased 2 x 1GB of Hynix memory both of these are matching sticks to the installed memory but when I installed them my laptop wouldnt boot at all. It would only boot if I had one stick in at a time.
    I tried switching top and btm ports and even when one stick was installed it says in XP, Vista and Windows 7 (yes I have tried all systems) 896MB available. I even tried using my other Hynix stick but it only booted and showed the highest stick of 1GB (896MB usable in Windows 7). After reading all the threads I'm just wondering if this is a hardware fault or is there a fix in the Toshiba world or perhaps in the Toshiba world the L series is nearly obselete and not worth the bother to help out the people who unwittingly bought thier merchandise.
    I apologise for being a bit down on Toshiba but a laptop which states what it can run and doesnt a company should hold its hand up and say yes there is a fault and help deal with the problem.

    You are seeing 896MB because the rest is reserved for the Graphics Card VRAM.
    Sometimes RAM can simply be not compatible, due to timing incompatibilities or RAM chip/controller design differences.
    What speed and timing is your original RAM?

  • Re: Satellite Pro A200 - Won't boot with 4GB RAM

    Hi,
    I've installed 2 x 2GB, but it seems it doesn't work. The funny thing is that when running just one memory strip (so 2GB) it works, when running both it doesn't work and it freezes. These are the Samsung 2GB 2Rx8 PC2 - 6400s - 666 - 12 - E3
    Ive' installed the latest BIOS update (64bit v2.60) for the Satellite Pro A200 and I am running Windows 7 64bit

    Hi caribman
    What Satellite Pro A200 you have exactly?
    I ask this because some A200 models were equipped with Intel 943GML chipset and these models support 2GB only!!!

  • PowerMac DP G4 Won't Boot With All RAM Sticks Installed

    A few weeks ago, my 800 MHz dual-processor G4 started having frequent kernel panics. I tried all sorts of things, including changing the PRAM battery, resetting the firmware, and resetting the PMU. Then, one day, it would only power up but not boot, so I took it in for repairs.
    The shop I took it to determined that the logic board was malfunctioning and replaced it. The computer no longer has any kernel panics.
    The machine was designed for three 500 MB RAM sticks, which is what it had ever since I bought it over five years ago. Now, apparently, it won't boot with the last one installed, though it will with two. The shop replaced the new logic board and and even swapped RAM, but the problem still persists. Neither the power supply nor the hard drive appear to be malfunctioning.
    Does anyone have any ideas what's going on? Any ideas or advice would be greatly appreciated.
    Thank you.

    squeakmaster, welcome to Apple Discussions.
    Have you tried the following with one 512MB RAM stick:
    1. Palce it in the first RAM slot. Does the Mac boot?
    2. If so, remove the stick & place it in the second RAM slot. Does it boot?
    3. If so, remove the stick & place it in the third RAM slot. Does it boot?
    The results of this test should reveal (1) if the stick boots in one or more RAM slots, the RAM is good and (2) if it fails to boot in a RAM slot, there is a problem with that slot.
    Do this with each of the tree RAM sticks & post back the results.
    When the logic board was replaced, was the firmware updated to be compliant with OS X. (Note - The firmware is installed on a chip on the logic board.) Check your Mac's firmware (Boot ROM version) version. Mac OS X: Available firmware updates
    http://docs.info.apple.com/article.html?artnum=86117 If an update is required, the update must be installed (using OS 9) BEFORE you install OS X.

  • MacBook Pro won't boot with new hard drive, but a different MacBook Pro will

    So here are the details. My friend and I both have 13-inch Mid 2010 MacBook Pro's. Same processor and specs since they were purchased at the same time, but originally had 250 GB hard drives. His hard drive failed and needed a new one. Put a 500 GB Seagate Momentus 5400.6 in his computer, and tried using a flash drive with "Install OS X Mavericks" on it to install Mavericks on his new hard drive. No matter what, it wouldn't install. I finally was able to install OS X 10.9.4 on it by connecting the new hard drive to my computer with a USB hard drive enclosure. I put the hard drive back inside his computer and it wouldn't boot (stuck on the gray screen with apple logo and a spinning wheel). I then attached to the hard drive to his computer externally with the USB enclosure, and then it booted and worked perfectly.
    So, it seemed like the problem was with something inside his computer, but then I switched our drives, and that doesn't seem to be the case anymore. I put my original hard drive into his computer, and his new hard drive into my computer, and they both booted and worked perfectly, so I have no idea why his computer will not boot with the new hard drive internally.
    To summarize, his computer boots with: 1) new hard drive connected externally (won't work if it's internal), and 2) my hard drive internally
    but my computer boots with: 1) new hard drive connected externally AND internally, and 2) my hard drive internally.
    Both hard drives have OS X 10.9.4 installed
    If anyone has any idea what's causing this and how to make his computer work with the new hard drive internally that would be greatly appreciated.

    So after switching the internal SATA cables from each computer, now we have
    His computer, with my SATA cable:
    1) Worked with every hard drive!
    My computer, with his SATA cable:
    1) Works with 1 TB Toshiba hard drive
    2) Works with 500 GB Seagate hard drive
    3) Works with my original hard drive
    4) Flashing folder with question mark with his old hard drive
    So it turns out you were right! Definitely had something to do with the SATA cables. But it's still strange that mine was able to boot with all the hard drives except the one that was originally in his. So it seems like it was some combination of his SATA cable and something else, since when his SATA cable was in his computer only 1 hard drive (my original) worked, and when it was in my computer, 3 hard drives worked. But at least its working, and I'm just gonna keep our SATA cables switched since that seems to work out fine

  • Satellite C655-S5128 won't boot up

    Satellite C655-S5128 shut down due to low battery before we could get charger plugged in.  Now it won't boot up.  It's stuck on the Toshiba logo page that also says to press F2 or F12 for setup/boot options.  There's also a faint beeping sound we've never heard before. After a while of pushing buttons an error message popped up stating no bootable device can be found.  Any suggestions are appreciated.

    Satellite C655-S5128
    Let's try a proper system reset, and see if this helps bring your laptop back.  Power off your system, unplug everything including the AC, remove the battery, press and hold down the power on button for 30 seconds, replace battery and AC, power on, when you see the Toshiba logo press the 'F2' key to enter BIOS Setup, in setup press 'F9' to load setup defaults, press 'F10' to save and exit, then try to boot into Windows again.
    Let us know what happens. Good luck.

  • IMAC will work with 3GB RAM but won't boot with $GB RAM

    I have a 20inch iMAC and it came with 1 GB RAM. I received 4 GB of RAM and did the upgrade. But I found that unless I had the original 1 GB RAM in either slot, the computer would turn on the fan, but never the screen and it would never boot. If I put the original 1 GB RAM in one slot and one of the new 2 GB RAM in another slot, it would come up and recognize 3 GB of RAM. I tried out both my 2 GB RAM and they both worked (to rule out bad RAM). But once I had both 2 GB RAM in the computer I run into trouble. This computer supports 4 GB of RAM according to the book and the new RAM says it is the right kind (Kingston 4 GB kit PC2-6400 for 800/667/533 MHz. I need the 667, so I should be good to go. Can you replace the original 1 GB or does that original RAM have something to allow the computer to boot? I have the latest MAC OS X updates....

    Okay I did get around this and got my iMAC working. It cost me an extra $92 dollars, but it was still cheaper than buying the 4 GB from the APPLE store.
    I exchanged my 800 MHZ backward compatible to 667 MHZ Kingston 4 GB kit for a PNY 4 GB kit that is meant for 667 MHZ and not just backward compatible.

    I installed this and my computer came right up and says it has 4 GB of memory when I do the Apple->About this computer. It seems to work fine now.

  • T420 won't boot with 2x4GB RAM (two identical RAM)

    Hi all,
    I am experiencing a weird issue that I'm hoping you'll be able to help me with.
    My T420 came with 1x4GB of ram (underneath the keyboard) and I wanted to upgrade to 2x4GB RAM so I bought exactly the same RAM again.
    Both RAMs work fine by themselves, in the bay under the keyboard as well as in the bay underneath the laptop. Both RAM were tested individually in both RAM slots. The laptop works just fine with either of the RAM individually in either of the RAM slots.
    BUT if I put them both in at the same time, the T420 won't boot. It switches on (screen stays black) and instantly switches back off. Without pushing any button, the T420 will then switch itself on again about 3-5 seconds later. This process is repeated indefinitely. I don't even get to see the ThinkPad security screen where you can access BIOS. I switched the RAM around in the slots but this didn't resolve the issue either.
    I have never had anything like that before. Does anyone have an idea on how to solve this problem?
    Thank you very much in advance.
    Regards
    Lippasti

    Has seriously no one ever had this issue? There must be a solution to this since I can rule out that either one of the RAM or the RAM slots is damages since each RAM works fine in each slot separately. I'm only experiencing this issue if I put them in simultaniously.
    Is there possibly any BIOS settings which I need to adjust prior to installing the second RAM?
    Not that I think it matters since I can't even boot it to the Windows screen but here are some specs. I am using a Kingston 512GB SSD and the other specs are:
    Here's the RAM I am using.

  • T420 won't boot with new Samsung 840 Pro SSD

    Hi all
    I seem to have a failed brand new SSD. Before I RMA it, please help me spot my stupid mistake
    I've just used Samsung data migration to copy my C drive to a Samsung 840 Pro 128GB SSD as usual.
    I went into device driver, and set the SSD to cache writes, so the SSD was working then.
    I removed the 320GB SSD, installed the SSD and rebooted.
    After the BIOS flash screen, the system halts with a funny symbol on the screen and a flashing cursor.
    It responds to Ctrl Alt Del. but doesn't get as far as testing the DVD drive.
    After replacing the SSD with the HDD and rebooting, all is fine again ...
    The BIOS shows AHCI mode, and the SSD and contents (in a USB3 drive caddy) are visible and readable.
    I can't use Samsung SSD magician because it won't see the SSD over USB (clever!), so can't work out how to upgrade firmware.
    This is an i5, 8GB, 320GB machine with 1600x900 screen, with XP Pro 64-bit.
    What gives?? Others here have posted with working 840 Pros in a T420, so I think it's compatible.
    Could this be a SATA2/SATA3 thing or AHCI? I can't see any SATA2/3 control in the BIOS - does it just auto-negotiate?
    Most grateful for any suggestions and thanks in advance
    Solved!
    Go to Solution.

    Hi woothoot,
    I'm not familiar with the Samsung data migration tool.  Is it actually cloning the drive, or just copying files and settings?
    With ThinkPads, it is usually recommended to have the target drive installed in the laptop and the source on the external connection.  Doing it the other way sometimes results in a non-booting drive.
    Can you rearrange things so that you do the clone op with the SSD installed in the T420?

  • Satellite Pro 460 won't start with new hard drive in

    I recently got a Satellite Pro 460 but it had no hard drive in.
    It starts great with no drive in but as soon as I put a brand new hard drive in it won't start.
    I thought that it might be to new a hard drive so I took my old working drive out my old Toshiba Satellite and still it won't start.
    Any one got any ideas why this is and what can i do about it

    It sounds like 80GB is too large for that model, I really doubt the BIOS and Chipset can support more than 8GB HDD. 8GB may not even work.
    Here is some information regarding different HDD modes and limitations: http://www.adminxp.com/hardware/index.php?aid=129
    504MB - limitation where the system is limited by the compatibility with the values of the BIOS system and the ATA interface by help of using the CHS mode. This limitation is valid for older computers 286/386/486. (1024 cyl 16 heads x 63sectors/track x 512 = 528,482,304bytes - 504 MB). In many cases special programs will help (Disk Ontrack Manager - Seagate, Disk Wizard - WD). Some operating systems can have problems with this software support and can have higher requirements on your knowledge of the OS and used programs.
    2GB - Limitation of the maximal value of the FAT16 file system partition for DOS and Windows 9x. Some older computers cannot address more than 4095 cylinders (4,095 x 16 x 63x 512 - 2,113,413,120 bytes)
    4GB Limitation of Windows NT - Partition with the FAT16 system cannot be higher than 4GB - Fdisk cannot be used for creating, but the Disk manager is used (Disk management in Windows 2000)
    8GB - Limitation of the BIOS system. For the support of larger capacities you need extended functions of the BIOS system. Limitations valid for the x86 computers and some motherboards with Pentium and Pentium II processors. Some other operating systems must know how to use the extended BIOS functions (Extended Interrupt 13). We can use Windows NT 4.0 as an example where you need an updated disk driver or the Service Pack. (OS - DOS 6.xx and lower, Windows 3.x and lower and some other older OS do not have the support of the Ext. Int13).
    8 GB - Limitation of the FDISK program in the DOS 6.22 OS.
    ?? GB - Possible problem with disks larger than 67GB under Windows 9x... See article WD800
    32GB - (65535 x 16 x 63 x 512 - 33,822,351,360 bytes) other limitation of the BIOS system.
    68GB - Possible problem with disks larger than 67GB under Windows 9x... See article WD800
    137GB - Limit for the ATA specifications (28-bit addressing for particular sectors - 268435455 sectors - 137,438,952,960 bytes)
    2,2 TBytes - 32-bit addressing used by new operating systems (in Windows 98 by help of the FAT32 file system).
    144 PetaBytes - a limit for new ATA specification using 48-bit addressing, in peparation. Maxtor, Microsoft, VIA, Compaq and other companies under name Big Drives participate the development. The standard should be implemented and authorized by the ANSI NCITS T13 Technical Committee organization (www.t13.org) in the prepared ATA/ATAPI-6 standard (see www.maxtor.com/bigdrive)

  • Won't boot with new graphics card

    Hi. I have a Pavilion P7-1058uk with a Cleveland-GL8 motherboard and onboard graphics.
    I bought a new monitor which has 2560x1440 resolution, greather than the onboard graphics can cope with, so have tried to upgrade with a Gigabyte GT630 card.
    When I startup, I now get to the blue HP screen but no further. If I startup with F10 or ESC pressed, I get to a black screen instead. Either way, I am invited to press Esc to enter startup but pressing the key has no impact and the computer just hangs. There is a repeated cycle of very quiet clicks which sounds like the HDD drive trying to start then stopping
    If I remove the graphics card and connect the monitor back to the onboard graphics then all is well again (but restricted to 1920x1080 resolution).
    Perhaps stupidly I assumed it was an issue with the power supply (300W) and not enough residual oomph to run the HDD. But having upgraded that to 650W it makes no difference. I also tried downloading NVidia drivers but it won't let me install them because I can only get the computer to work without the graphics card, and Nvidia won't install because it can't detect the hardware.
    Any ideas/help would be much appreciated.

    OK thanks. This card doesnt require a six pin connector but it is interesting that your comment implies that those that do still take power from the motherboard but topped up with the six pin connector. As opposed to taking all power from the six pin connector and nothing from the motherboard. I am not making a statement that equates to your analogy. All cards plugged into a motherboard I/O internal slot are powered by the motherboards power distribution subsystem.  
    One last question - should I have uninstalled the graphics driver for the integrated graphics or is that unnecessary? I have read that the motherboard turns the integrated graphics off when it detects a dedicated card.  I have not done so and am a little wary of uninstalling the existing driver in case things still dont work and it gets tricky to revert back to where I am now.
    Andrew
    No. You won't need to uninstall the driver for the integrated graphics. The OS will only load the driver for the graphics card when one is installed.

  • Imac won't boot with new hard drive installed

    So I installed a new 1Tb caviar black in my PPC G5 Imac, but when I turn the computer on, I get no video, no startup chime, nothing. The power light does come on, and fans start running after a minute or so, but thats it. I can't boot from the install disc.
    The computer boots up as expected when I remove the drive(startup chime, grey screen, missing folder icon).
    Any suggestions to what the problem is? Any help would be greatly appreciated.

    wierd i have similar problem. I removed HDD after crash to backup in an enclosure before reinstalling os again, put the hdd back and connected the hdd sensor backup (although i thought it was a knock sensor..doh!) . Mac wouldnt start, no screen, no chime, nada, but sleep light stays on. With PCs this usually mean CPU fault so i removed RAM to see if could get a BEEP meaning CPU is ok as it spots ram. No beep. So after checking everything i stripped out ram, hdd, airport and battery and reset PMU, tried again and now i get beep!! so cpu works. slowly adding everything back in and trying power up, last thing to go in was hdd sensor and sure enough when this is connected i reproduce the symptoms. So i disconnected the sensor and tried and i get chimes etc... Ive inspected the cable and made sure is connected right way up and still cant get to work. So it seems sensor is goosed! Debating wether to replace just yet

  • P7N Diamond won't boot with new Intel Q9400

    Hi
    I recently bought a new Intel Q9400 CPU to replace my old Q9450 that was broken and causing the computer to freeze. I tried to install the new Q9400 CPU and the computer would not boot. The red LED on the mobo was on. When I pressed the on button the fans span for about half a second but then stopped and the machine shut down. I have replaced it with a firend's E8400 and it boots fine again.
    Before I installed the Q9400 I flashed the BIOS to v1.4 so I was confident that it would work but it didn't. After it didn't work I cleared the CMOS and it still didn't work.
    Is there a compatibility issue with P7N Diamond and this CPU? My mobo is revision 1.0, does this make a difference? If not then I suppose the CPU must have been DOA and I'll need to RMA it.
    Thanks,
    Jim

    Very unusual for a CPU to become "broken"--more likely the PC developed another problem? I'd test the 9450 on another system too if I were you.

  • Tecra a3 won't boot with new hdd

    hi
    tecra a3 model no PTA30E-02G008EN
    i have a new 250gb hdd that has a clone of my previous (when working ok) hdd using EASEUS.
    but it will not boot. after the BIOS it has a blank screen with a flashing white cursor top left.
    the hdd appears ok using a usb caddy.
    are there any obvious problems such as a maximum hdd size, or a BIOS update i need? Might it work if a split the 250Gb hdd into two partitions?
    thanks for your help
    mark

    Mark, it's possible (but very unlikely) that your BIOS does not support 48-bit LBA. If that were the case, the partition would need to be less than about 137 GB. The information is in here.

    Sorry, I don't know why the restored disk doesn't work. You could try to restore it to its original out-of-the-box contents using Toshiba recovery media. I'm guessing that would work.
