Memory hardware issue... won't boot

I can't make heads or tails of this one...
I have a dv5z-1000 laptop and up until about 2 weeks ago it was all running okay.
Long story short... I thought the problem was heat and it probably was part of the issue. I have replaced the thermal pad on the cpu with grease and made a shim for the gpu and also added grease to it.
Anyway. The laptop won't boot if I have both sticks of memory in it. I can put each stick of memory in the laptop by themselves and it boots. However, as soon as I put both sticks in the problems starts...
I have had the same memory for over a year with no problems and I don't know what to try next.

Hello Mart,
please review the keyboard plug, these pins bent very easily.
There are occasions when a direct-connect keyboard can help,
e.g. when the system was powered down by power management and there is no key-switch to power-on ...
STOP-A is basically a BREAK (use ALT+B in TeraTerm Pro to generate this signal).
During POST the LEDs of the direct-attached keyboard show the current status of POST.
and there are times when it is best to remove it and go with
the console connection, off the TTYa port.
The early phase of POST is only visible on the console (serial, RSC, LOM, ALOM), because the display adapter (integrated or add-in board) isn't initialized yet.
If a monitor doesn't support the current display mode, the monitor doesn't sync and the ability to change the mode via serial console is very valuable.
Sometimes reverting to the default OBP settings is required. Either use STOP-N with a direct attached keyboard or BREAK via console and then
set-defaults
setenv auto-boot? false
reset-all
As mentioned before, not properly seated memory modules can cause this hang.

MacBookpro Early 2011 graphic issue won't boot

Hello,
My Early 2011 MacBookPro suddenly suffered from graphics issues for a few days then it won't boot at all.
The hardware test says it is ok and my hard drive too. But when I want to boot, the apple appears and the dong too, but then blank screen. It is the same with a bootcamp boot, but with a blue screen with lines all over the screen. The recovery partition doesn't start either. But I can access boot from my hard drive with another Mac on target mode.
Anyway Apple doesn't admit there's a problem a want me to pay the reparation, because they don't report it as a real problem, saying that I damaged the computer. But there are threads here and all over the internet, and they don't want to do anything.
On the phone, the apple guy told me that I had to pay 80$ to see if there is any problem , and " maybe if we see there's a fabrication problem, we'll fix it for free ". Do I have to trust them ? What can I do to ?
Thank you

Dual 2.5 cooling issue: Won't boot.

I have a dual 2.5 G5 that I've had since it was new in in july 2004. It's never given me any problems.
Recently it started "gurgling" (it's the best way to describe it). I was worried about the dreaded leaking issue so I tore it apart looking for leaks.
Good news: No leaks. Bad news, it won't boot now.
In the process of assessing the situation I checked the coolant level. To my surprise the system was pressurized quite a bit, even though it was stone cold. I don't understand this. I also get the red LED's on the mother board glowing indicating overheat, the cooling fans run at high velocity, and the computer won't boot.
I am in the process of rebuilding the water pump as a preventative measure, resealing the two O-rings and the diaphragm. Everything seems in working order.
I hope it will boot once I reassemble it, but I'm in a situation where I MUST have it up and running by monday.
Any suggestions?

Hi tarmaque-
It may not be so much about pressure as air in the system. You said yourself that it was pressurized when you disassembled it. That is a huge clue! That fact alone would certainly make me think that there should be pressure.
I think the higher boiling point under pressure is a factor. There isn't much fluid and it must dissipate a lot of heat.
Water cooled engines absolutely are "pressurized"-ever take a radiator cap off of a hot engine? A cooling system must be able to handle pressure as (duh Daddy) liquids expand when hot.
Luck-

K7N420 Pro -- RAM issues -- won't boot/crashes

System info:
CPU: AMD Athlon XP 1900+
Motherboard Model: K7N420 Pro
Memory: (Varying, this is the problem, explained in post: but to begin with the system had 2 modules of 256MB PC2100 266mHz. Brand name unknown, some generic manufacturer. For reference's sake, the motherboard has THREE memory slots)
Video card: NVIDIA GeForce2 Integrated GPU, GeForce2 Integrated GPU, 32MB
Hard Drive: Western Digital 80GB
Other cards: None that I know of
Operating System: Windows XP Professional Version 2002 Service Pack 2
Power Source: Addtronics 300w (3.3v/18a, 5v/30a, 12v/9a)
Okay, so obviously we've got an old, old beast here.... But she's served me well, and I'd like to get a little more out of her. So here's the ongoing (very long, I'm sorry) saga:
The computer started doing crashing on me some time ago; lots of Blue Screens of Death, no error messages that gave me anything reliable to use for diagnostic purposes. Eventually it just wouldn't even manage to boot, each time would give me a BSOD. I opened the case up, checked for anything obviously visually wrong (blown capacitors etc), did a good thorough aircan dusting, popped out the two 256MB chips (let us call them Chip and Dale), and popped them back in.
This did indeed have a result- now we didn't even make it to the BSOD! All I got was a repeated ominous beeping and nothing coming onto the monitor at all. I then tried to put in only one chip at a time. Results: Chip works in slots #1 and #2, but not #3; Dale works not at all. (By "works" I mean the computer boots normally and runs normally, for at least an hour, the most I've tested it. Runs SLOW, of course, at 256MB, but runs. By "not works" I mean we get nothing on-screen, and the repeated ominous beeping.)
I presumed I had bad memory on my hands with Dale and that I needed new memory anyways, so I headed to Fry's and picked up two sticks of Patriot 512MB PC2100 DDR 266mHz-- the same specs as the old memory, excepting that it is 512MB instead of the 256. (According to Crucial.com, my motherboard's slots should each be able to support 512MB.) Let's call the Patriot 512 chips Bill and Ted.
Results with the new memory: Neither will work in slot #3. Logic dictates slot #3 is bad. Bill will work in slot #1 or slot #2. Ted will work only in slot #1. The computer will NOT boot if both Bill and Ted are occupying slots. (It also won't boot if Chip is occupying a slot and either Bill or Ted are in another slot.)
(Doesn't this sound like like one of those old logic problems where you have to sort out who owns which house?)
So the best I can get out of her right now is to stick Bill or Ted into slot #1 and proceed with the same 512MB that Chip and Dale used to give me back when they cooperated. However, new wrinkle: neither Bill nor Ted will get along with the computer for anything more than about a half-hour-- then, the computer crashes, tries to auto-reboot, and starts doing Black Screen and Ominous Beeping again. The RAM has to be popped out and put back in before it will boot normally.
*deep breath* I know that was long, thanks to anybody who read this far. Does anyone have any ideas as to what could be causing these problems and/or how to fix it? I've reached the end of all the knowledge I can put to work on this problem.
If I haven't been clear on anything, please let me know, I'll try to answer.

Hello,
Are you 100% sure that slot 3 is clean/dust free?
Memtest is a program that writes patterns to the memory.
The program then tries to recall the pattern(data) stored in the memory location.
If the memory is faulty the pattern(data) may have altered (goes corrupt) and the program will report an error.
Use just 1 stick at a time in slot 1.
Patriot Bill, let memtest run for say 3 hours.
If everything is ok you will not see any errors on the screen.
Then turn off and remove patriot Bill.
Insert patriot Ted into slot 1.
Run memtest again for 3 hours.
Again if everything is ok after the 3 hours it means that both Bill and Ted are ok.

Memory upgrade | PC won't boot

Hi,
Most DDR400 works at 2.7V some can even go higher. So adjusting the voltage to 2.6 and then 2.7.
Yes, DDR400 will work with P4 and Celeron 400FSB. Have a 2.6 Celeron 400FSB in 848P Neo S mainboard and is running fine. (Also tested in 865 Platinum mainboard (dual channe)l and 845GE max mainboard.)
The only other suggestion is you ask a friend to MEMTEST for you.
Where did you download bios from? As the MSI bios download for "link"mainboard is only 2.1........

Passed hardware test, won't boot

I am trying to get my 2008 iMac running again. I replaced the hard drive after it quit working. I have the boot cd in and when I ran the hardware test there were
No issues. All that I get is the missing file (flashing question mark) screen. I can't get it in verbose, or boot it from the cd. I've been using mac since the early 80's and have never had to have one professionally fixed. Any ideas?

I know... I can't figure out why it won't. I've even tried multiple keyboards to be sure... It stays on the gray screen longer than usual, and goes to the missing file icon.

MacBook Pro HD issues; won't boot to any drive; need to recover data

*Apologies in advance for the lengthy post. I just want to be sure I include as much detail as possible. Thanks in advance for reading all of this and offering any thoughts and suggestions.
I have a 13-inch late 2011 MacBook Pro running OS 10.7.
The computer recently began booting slower and slower until finally one day it did nothing but show the gray boot screen with the apple and a spinning circle and/or progress bar at the bottom. It won't do anything else. I assume it's the HD; no surprise there. What's killing me is that no matter what I do, I can't boot to any disk, internal or external, can't mount it in target disk mode, and can't repair it or recover data, which is a first for me with any HD. However, the computer still clearly sees the drive, and the drive sounds and runs normally (meaning no clicks; appropriate amount of whirs and such).
What I've done so far:
Reset PRAM — no help
Reset SMC — no help
Boot in Safe Mode — same result as regular boot: gray logo screen with spinning wheel
Disk Utility message:
Verify Disk — "Error: This disk nees to be repaired. Click Repair Disk."
Repair Disk — gets as far as "Checking catalog file" then shows "Keys out of order". Next is "Rebuilding catalog B-tree." Then "The volume Macintosh HD could not be repaired."
fsck — same as Disk Utility: "Keys out of order (4, 22016)", "Rebuilding catalog B-tree", then "The volume Macintosh HD could not be repaired." FILE SYSTEM WAS MODIFIED." ...over and over again
If I hold Option while starting the computer, it gives me only two drives to boot from, regardless of any other external HDs or flash drives I have attached: Macintosh HD (internal), and Recovery HD (internal partition). If I choose Macintosh HD, it's hit or miss whether it prompts the Disk Utility screen or just gray-screens forever. If I choose Recovery HD, it successfully runs Disk Utility every time. Here's the thing, though — if I attach an external HD, it doesn't see it during the initial Option-startup. However, from Disk Utility I'm able to select a startup disk from the menu to restart into. It sees the externals in there every time and lets me select them as startup disks, but upon restart it returns to the gray Apple logo screen with spinning wheel and/or progress bar at bottom. Sometimes it also sees the internal Macintosh HD here, but selecting that is useless. I can't actually boot from any disk, internal or external, running full OS or even just recovery software.
I've tried using TechTool Pro 8's edisk and ProToGo bootable drives, but again, the MacBook only sees them from Disk Utility only (not on Option-start), and I can select them, but it doesn't actually boot to them; it reverts back to gray screen.
I've installed a full version of OS 10.10.2 on an external hard drive, complete with DiskWarrior 4 on it, but same problem as above — it sees it in the "Select Startup Disk" menu, but not in the initial Option-start or successful reboot.
I've tried booting from a DiskWarrior 4 DVD using C-startup. It recognizes and spins the DVD from the get-go. Eventually it boots to it (after about 20 minutes or so of reading the DVD). I'm able to launch DiskWarrior 4 and start a rebuild. However, it goes all the way through "Step 6: Constructing optimized replacement directory... Overlapped files detected: 7 ...Step 7: Finishing construction ...Step 8: Reading from disc, one moment please..." and then the computer kernel panicked. This happened several times. I reset the PRAM again, then retried DiskWarrior DVD boot, this avoided a kernel panic and it got as far as "Comparing directories... Step 9: Recording any file or folder differences; 3,449,089,956 tests..." and then DiskWarrior and the computer both freeze and I have to force shutdown.
The drive will not mount to another laptop in Target Disk Mode.
Disk Arbitrator immediately sees the the faulty laptop HD, but won't let me mount or unmount it. It's just there, grayed out.
Data Rescue 4 is able to see the faulty laptop HD through Target Disk Mode, even though the drive itself will not mount to my desktop. I am able to scan the drive using DR4, and start a data recovery process. However, DR4 is dumping all recovered data into "User Defined" ai (Adobe Illustrator) files, which makes absolutely no sense at all. What's more, the files aren't able to be opened by any program. Even files that it hasn't recovered into ai files, like txt and mpegs, cannot be opened. I've tried recovering from both the drive itself and from a clone of the drive (made through DR4), with the same result each time.
So, all of that said, I guess my first question is what the **** is going on? The drive mechanically is functioning fine, but there seems to be an issue with its readability (and the directory/files?).
What's more, why won't this laptop mount ANY drive? I should be able to Option-boot into any drive, especially if the USB ports, drives, and OS's are all fully functional, right? Is there any workaround I'm missing? Even if the internal drive and data are just screwed, what's causing a total lack of mounting or booting of any drive, internal or external?

Holy crap, I got it to work.
Essentially, I just waited until DiskWarrior reached Step 9 and told it to skip the step before it had a chance to freeze. It skipped successfully, moved on, rebuilt and replaced the faulty directory files.
So far the computer is booting like normal, I can log in, and I'm currently copying all of the data to an external as I type this.
I still have no idea why the computer wouldn't mount or boot to any drive, but I guess I'll deal with that later.

Format issues- won't boot from OSX disc

Help!
I've been having some issues with my iBook G4 recently (it seems every program will randomly quit unexpectedly and it's generally rather slow) so I was thinking I would just wipe the drive and start afresh.
But I can't seem to boot from the OSX install disc. There's an option in the disc itself to restart and that didn't do anything and pressing "c" while restarting still starts things up normally. I've tried zapping NVRAM, PRAM, I went through OF and did reset-all and set-defaults (I'm not even sure if that was necessary- I'm desperate!) and nothing will work.
Help, please!

In order to erase your internal hard drive, you have to be booted from something else. I think you could do this from another Mac in FireWire Target Disk Mode, but I have never done this myself.
http://support.apple.com/kb/HT1661
Is there a reason you don't want to use FireWire?
The biggest problem still seems to be that either your disc or your optical drive is not working properly. Even if you do succeed in erasing the drive, there is still the problem of reinstalling the OS. I think there are methods of doing this with FireWire Target Disk Mode, but I have just never done it myself, so I hesitate to give any instructions.
If you can, you might see if you can borrow an external optical drive and see if you can boot using that. If so, you can erase and reformat your internal drive using Disk Utility and reinstall the OS that way. If an external optical drive won't work, there may be a problem with your disc.
Good luck!

CD/DVD-rom Issues; Won't Boot

   Hi, I am having a problem booting when I remove my CD-Rom 'Slave' or try to replace it with a DVD-Rom.
Below I will give my computer specs.
I have 2 hard drives, so the Primary IDE slots hold my 2 hard drives; one a
Master and the second one is the slave to the master.
On the Seconday IDE slots, I also have 2 cd-roms, one is the master and the
other is the slave to the master. The master is my cd/read/write cd-rom. I
want to leave it and change the slave cd-rom to a DVD-rom (not a dvd r/w
rom)...
I bought bestbuys dvd-rom, took out the 'slave' cd-rom and put the dvd-rom
in with the pin set for the slave. I booted my computer and it wouldn't boot
pass the first booting page. It wouldn't boot into windows.. What could be
wrong?????????
I took the new dvd-rom back out and left the secondary slave empty and tried booting and it
wouldn' t boot with nothing in the secondary cd-rom bay .. wierd to say the
least.. Like I said the secondary IDE slot is the Master of r/w cd-rom and I
never removed it or touched it, it is still there..
I then put my old cd-rom back in the secondary (slave) and waited a few
mintues and booted up my computer.. It booted with no problem.. I repeated
this whole sequence several times with the same results.. I for the life of
can't figure it out... My computer should boot with or without the second
cd-rom (slave), shouldn't it????? Adding a cd-rom or a dvd-rom should not keep my
computer from booting up should it?????
In my cmos, I have it set to boot-up with the hard drive as my first
boot-up, the second is the cd-rom.. but I don't see how removing or replacing
the 'slave' cd-rom would prevent it from booting into windows..
Yes, I have check the cables, settings and everything in my whole computer.
Can someone please tell me what is causing this.. I need a dvd-rom drive.
not paticularly the brand of the dvd-rom I just bought (which I have already
took back anyway) but I do need to get a dvd-rom asap in my computer so I am
hoping someone might know a solution to this problem..
Thanx for any help,
Granny (below are my specs)

Sometimes drives are picky and fight over who is master/slave. Try switching them.

Memory upgrade | PC won't boot

Hi everyone. I've just upgraded my memory from 256MB to 1GB, I took out the 256 one and only inserted 1GB one so that they don't clash as they are of different makes. Now when I start up my PC, my monitor says 'Monitor is working, check you PC or cable' and nothing boots up, not even that screen where I can get into system setup/bios etc. So from there I have to turn it off by pressing the start CPU button for 5 or so seconds.
I can run memtest only after booting up when it goes to that stage where floppy or cd drive is checked, but it doesn't. CPU does start but nothing comes on the screen, instead the monitor says 'Monitor is working, check your pc or cable'. when I put my old ram in, it runs the memtest, no problems.
Help would be loved here, my £40 are at stake, please. :(

Added new memory, now computer won't boot at all

Hello
I added a new pair of 2*8GB Coursair memory along with my old memory which was 2*2GB, for a total of 20GB Ram. It was working fine for a day (except one random restart), but got steadily worse. Yesterday iMac was shutting and restarting more frequently. I decided to remove the old pair thinking the different brands may be causing a disturbance. I did, but the restarting didn't stop. I removed them again to try put it back more firmly or something, that was the last time my iMac booted. It will show the apple logo, then some short loading bar will come up, then it would promprtly shut down.
I tried putting back my original RAM and it still wouldn't boot. Tried them individually, new old, different slots, nothing worked.
So I guess I damaged my memory slots or all my RAM modules stopped working. Any ideas what to do next? I've already requested a replacement for the new RAM.
Some extra info:
-Old ram was running at 1333Hz and new one was 1666Hz, I tried them together .
-First time I tried to remove RAM, I tried to pluck them out with my hands by leveraging the sides with a small screw driver. Realised I had to pull the black thing later on. Don't think I applied too much force though.

Well, you should not mix different specs RAM. And, it's best to purchase RAM for the very finicky Macs from either OWC (macsales.com) or Crucial which guarantee the RAM to be Mac compatible and offer a lifetime warranty.
I would guess that the new incorrect spec RAM is the problem. Additionally, you might have damaged the slots inadvertantly.
You might need to take it to your nearest Genius Bar for a free evaluation. Additionally, I would return the RAM as not being compatible.

Memory upgrade - now won't boot or wake when peripherals attached

I just bought 2x1GB PC2700 333Mhz 200 Pin DDR SODIMM and now if I have my external monitor attached or anything USB attached (even just a mouse) it will not power up. When I unplug the monitor and/or USB it powers up fine.
I've already had the memory exchanged as the original upgrade memory was incompatible (had the same incompatibility problem when I replaced one of the 256's for a 512 at time of purchase).
Anyone else have this or know the fix?
It's not deadly, just annoying to not be able to put it to sleep after 4 years of using it without any problems.
Appreciate any help.

I have the same problem. This just happened a couple weeks ago. I purchased a discounted version of 10.4 online, and installed it. That's when everything started acting odd. I have 1.25 gig of RAM. One day the computer locked up, rebooted and clicked on about this mac and it said that only 256 of RAM was installed. I turned the computer off, opened the RAM slot, removed the memory and re-installed. All was well. A couple hours later, the same thing happened again. I thought it was the RAM going bad, so I swapped the location of the RAM, put the 256 in the lower and the 1gig in the upper. Restarted and waited. A couple hours go by until it locks up, then Re-boot. This time it says I only have 1 gig of RAM. Definitely the lower slot going bad on the logic board. ifixit.com has the board for $450, but out of stock. Funny how Apple's recall is only for the 1.5~1.6 machines...

Hardware Issue - Won't Accept CD's

Last night I was using my CD on the Mac Mini, and after exjecting the CD it made a few NEW noises. Now I attempt to put a CD back in, it seems to have something on the right blocking the CD from being inserted.
I have no problem opening this machine (yes, I know how), but I'd like to know if anyone else experienced the same problem AND fixed it. I figure the CD drive got jammed in the eject mode, and hasn't reset.
Suggestions? (BTW: I've already tried the re-boot holding the eject button down twice - no dice)

OK, it works fine for now.
After getting the proper sized screwdriver from Home Depot, I was able to open the cover to the Super Drive directly (4 screws).
The one actually blocking the CD from entering was lock (if I forced it, it would have broken), but towards the back of the dive another arm was engaged, so I gently pushed it back on the same plan as a CD would -- it was a little stiff but it worked. That move then disengaged the other portion blocking the CD from entering. Then, I reinstalled in back into the Mac - make sure the Mac is off (yes, I left the drive cover off).
After booting up the mac, the drive when through it check cycle (the parts actually raised above the plan). Once that worked, I inserted the CD. It worked fine without having the drive cover on top - I could see the full CD spins like normal. I tested it and made sure I could access informational, and it all worked fine.
That's it folks. I save money (for now $110) and have my mini up and running again.
Since it really had no reason to break in the first place, it's likely that the error might happen again, but until then - I have a working drive.
(Sorry, next time I'll take photos)

Satellite A200 PSAEOE won't boot after memory upgrade

Hi, I am first time here.
I have bought a Toshiba A200 PSAE0E-03J02JDR with 2 GB ram memory. I bought a pair of Corsair ram (2*2GB VS2GSDS667D2). After I installed the memory the computer won't boot. I have intel 945 chipset, which is capable of 4 gb (manual page1-2). The bios version is 1.8 from 2007.
Can anyone help me, please.

Hi
The A200 series supports different chipsets;
Intel 945PM
Intel 945GM
Intel 943GML
As far as I know your notebook supports the *Intel 943GML* chipset and this chipset supports max 2GB RAM.
Take a look in your notebooks user manual *Page 18.*
Summery: 4GB RAM are not possible and therefore your notebook does not boot up.

Memory hardware issue... won't boot
