New system, random shutdowns w/ infinite reboot-cycle afterwards

The problem:
When using the machine normally, it will shutdown/go out. 2-3 seconds later, the machine turns on by itself, stays on for 1-2 seconds, Shutts off. Comes back after 2-3 seconds and shuts off again after 1-2 seconds of been on. It looks like it would continue this cycle infinitly, if I didn't physically turn off the power supply to the system. (I let it repeat 7-8 times, before I decided to cut off the power entirely from the system.)
After cutting off the power entirely, I'm able to boot it up normally next time I plug it back in. The problem repeats itself, when it decides to shutdown randomly while in WindowsXP.
This is my first MSI board. I chosed it because reviews showed it, that at stock speeds, it was the fastest in gaming benchmarks. I guess, I should've checked for stability issues first on the web :( The system:
MSI 875P Neo Motherboard
Intel P4 3.2G 800 Processor

Sure is useful, as I am sure most people, including myself, don't realize how much wattage they are consuming.
These threads have surely convinced me of the value of a quality PSU.
Was hanging out at CompUsa a month ago talking to a nice, bidget-minded feller who wanted all the cool light mods, and a cheap, but cool case, with no inkling of the power needs. Being the disciple I am now, I wish I could talk to him today and proselytize about power...

Update to 10.6.7, system random shutdown at mbp mc721.

I check the graphic card setting in gfxCardstatus.
System will be random shutdown by using ATI6490, but force to use intel HD 3000 not so.

HI kong,
Welcome to the forums.
Have you recently upgraded/ replaced the computer ram? Have you tried running Apple Hardware Test?
Have you looked at the console log to see what's listed at the time of the shutdown?
Have you tried a SMC reset or a NVRAM reset?

FF 13.0.1 upgrade is in an apparent infinite reboot cycle. I'm on XP Service Pack 3. How do I fix, or recover bookmarks so I can go to an earlier version?

I believe I was on FF v13.0 prior to this upgrade.

The exact message I get when trying to start FF is "Your computer must be restarted to complete a previous upgrade of Firefox. Do you want to reboot now?
I've rebooted 4 times and continue to get this message.

Mac mini caught in infinite reboot cycle

Hello together,
My Mac mini is all messed up since yesterday: I had a message on my screen that I need to swtich my computer off (which I did) and after that the mini just won't start any longer: I hear the Apple sound, the screen gets all white (no progress wheel, apple logo or the like, just a plain white screen), that takes about 5 to 10 seconds, then the screen gets all black, the Apple sound sounds again and the whole things starts over.
I tried to boot from DVD: No luck Pressing C, Alt or any of the other fancy key combinations doesn't have an effect (could that be due to the fact that I have a wireless keyboard? Or is that irrelevant here?)
Thanks for all your help/ideas/hints on where to start looking...
Cheers,
Sebastian

Hi there,
ok, got a USB keyboard and did the reset of the SMC (unplugged everything, waited, replug, switched on) as you suggested: No luck so far. Am still stuck in the infinite loop
Have only my external speakers connected to the mini (via 3.5mm jack), removed that (no drive, no network, no TV etc.). The Mini is connected to my old fashioned TV via the Apple DVI to S-Video adaptor.
I don't have a UPS, just a surge protector.
Am a little bit at the end of my ideas - any more hints what it could be?
To recap what I tried to do is:
- Disconnect the mini for several hours (over night)
- Pressed 'c' button while start-up to boot from the Leopard DVD
- Pressed 'alt' button to start bootmanager
- Pressed 'd' button to start AHD
- Pressed 'alt' + 'command' + 'p' + 'r' to reset P-RAM
And I still get only this behaviour: Start sound, + white screen, DVD drive spinns up, spinns down, screen blacks out, and the things starts over... After a larger number of restarts it can happen that the computer gets stuck with just a white screen (no restart in this case). I can only switch off by pressing the power button for more than 5 seconds.
Again, thanks for your help!

My iPhone 5 randomly shutdown and rebooting doesn't seem to work for me, what should I do?

It also happens when I'm charging my phone, and also the battery percentage doesn't show that correct battery level not unless I turn off and on.. I tried rebooting the phone but it doesn't seem to work for me, random shutdown still happens..

Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

New heatsink yet random shutdown!!

Hi y'all,
So my MB was repaired 2nd time with the new heatsink part and this was on Oct. 3rd.
Today on Oct 13th the random shutdown has reappeared yet AGAIN.
I have just about had it this macbook.
Did any of yours had random shutdown after the reparation with the new heatsink part??
And do anyone know if I will be eligible for a refund and/or replacement since I have had to deal with this problem three times now?? (still in waranty period)
Thanks

jhawk - three possibilities. First, are you sure you got the newly designed heatsink? Oct 3 would be right about on the cusp between new heatsink and the old replace the logic board 'fix'. Second, assuming you did get the new heatsink your computer should then have been retested on diagnostics and a new logic board installed if it failed and if it passed it would be sent back without a new logic board. But it is posible that in some cases RSD is masking (and maybe even causing) logic board issues that don't show up on the diagnostics then but show up later. This could be your problem and if so after getting a new logic board your MacBook problems would be over. Third, and I hope this isn't it, Apple hasn't found all the causes of RSD yet.
It is still a little too soon to know about this either way. Based on past RSD repair experiences, if the redesigned heatsink does fix the problem we can expect to continue seeing RSD me too messages through October and probably into the first part of November but the frequency should begin to die down in November.

New E65 randomly rebooting and apps crashing

Dear Nokia,
Pleas etake the time and effort to supply a working E65 firmware for downloading since the one that my E65 was shipped with (1.0633.18.01) works rather poorly:
- The webbrowser will crash randomly
- The network connection will quit randomly
- The phone will reboot randomly
And this while I only have used about 0.1% of all available features on said phone. One could say the failure rate is rather high.
I upgraded from a Nokia 6310i that actually still worked quite well but was not Bluetooth compatible with my new car-kit so I made the dubious decision to upgrade (downgrade?) to the E65, since the N95 was just a little too much of a good thing for me.
As it turns out the N95 already has firmware upgrades while the older E65 that would benefit from less bugs too apparently was forgotten.
Please oh please fix your product.
Sincerely,
sprins

Do the newer macbooks also suffer random shutdowns?

Hi there, I'm considering buying a Mac, and I'm stumped for choice. I'm choosing between an iMac 17 inch to replace my PC, or a Macbook for portability. If I am going to be buying a Macbook, I want to know if Apple tested them for random shutdowns first, just so I know that I won't be buying a machine that I'll have to send out within the first week of recieving it. If the new macbooks (as in the ones with Core 2 Duo processors) still suffer random shutdowns I'll probably go for an iMac instead.

You're claim that everyone who owns 1 (22 out of 25 people) has a problem is total hogwash. Geez, why would you say such a thing? I recently sold my Core Duo BlackBook, one of the first 500 off the assembly line), and never once had a problem with it - ever! I really didn't want to sell it because it was such a fine workhorse but I wanted 801.n on my home network and needed a C2D to get that. I carried it around on all my hospital rounds and it contained every one of my patient's health records. If MacBooks were as you claimed then Jobs must of personally touched my BlackBook with the luck of the Gods!
Before it was even sold I bought another C2D BlackBook, loaded it with 3Gig of RAM (yes, you CAN upgrade to 3Gig) and the thing is a most excellent machine. Faster, sleeker, and works like a champ. I transferred all my patient's records within 20 minutes.
My advice: don't believe the naysayers. Especially here. These forums were established to assist MacBook users with all issues, including problems. But the number of problems is miniscule and those you read here come from less than 1% of the MacBook owners.
The Core Duo BlackBook sold for just $200 less then what I paid for it and it was fully loaded with everything I could put on it when I originally purchased it. I used it a full year (May to May) and figured the $200 was a year's worth of cheap rental.
BTW, I got a better BlackBook for less money this time around. Faster CPU, larger hard drive, more RAM and a superior laptop to those of my colleagues - what more could a geek physician ask for?

To Everyone with Random Shutdowns! (Solved! REALLY!)

Hey all,
I had posted about a week back about my Macbook (Core duo white, late 2006), it was having the same symptoms as some of the others with the known random shutdown syndrome (RSS). Like many others I had thought it was the end of my macbook and the logicboard needed replacing because that is what the 'genius' people do, but I was still wondering what would cause it. It would randomly shut off! (or so I thought) I'd be typing in Safari, watching a youtube video, and even playing games, it would just shut off and I could hear the hard drive spin down. I'd restart and it would do it again sometimes right away, sometimes hours later.
This got me to thinking (like others have said) that it must be an issue with over heating. To test my theory I backed up my HD, and tried to reinstall Snow Leopard after zeroing the HD (as a fresh install). During the install process the Macbook's fan started to get loud and then it happened, it died again! So, this proved to me that it is NOT a software/OS issue at all, which means the said efforts in other posts of changing screen saver and energy saver settings had nothing to do with the cause! Aha moment!
I thought to myself... something is making it shutdown, obviously, and has to do with too much heat as the fan was going crazy even while reinstalling the OS. After reading many posts on different support forums I came accross the possibility that it could be the heatsink and/or sensor that is attached to it. I also found out that this "RSS" only applies to the non-unibody, core duo, and core 2 duo macbooks... you know what that means?
These models are the only ones with the shared memory and GPU on the same heatsink! GAH! A possible solution presents itself? To make a long post even longer... I removed the keyboard, carefully unscrewed the heatsink and fan and what did I see? Cracked and dried out thermal paste on the CPU AND GPU, they are both under the same heatsink after all, this was bad, really bad.
Luckily I had some Arctic Silver thermal paste in a tube from years ago when I upgraded my PowerMac CPU. Using some rubbing alcohol and a soft cloth I removed the crud on the heatsink, processor, and GPU (I might add that there was way too much paste on there in the first place). I waited an extra few minutes to make sure the alcohol evaporated, and then I applied a small (dime sized) amount of thermal past directly onto the two chips, I aligned the heatsink carefully and gave it a very small gentle push down onto the chips, reattached the sensor wire to the mainboard, and screwed the heatsink back in.
After putting the keyboard back on and making sure all screws were in... I immediately turned on the laptop and reinstalled the OS. The OS install took approximately 10 mintues! (crazy!) The last time I did that it took over 30 mins to install! I was stunned!
After the OS installed I let the computer idle and shut down, I let it sit for about an hour to allow the paste to contract as it cooled. After starting up again I immediately downloaded Temperature Monitor and installed it (I did have it running when my mac had RSS by the way), here are the results to prove my theory:
My Macbook with RSS:
CPU1 and CPU2 Idle temp - 114 degrees (F)
Heatsink temp - 128 degrees (F)
Approximate over heating temp - 184 degrees (F) (causing the heatsink sensor to shutdown the laptop)
My Macbook with new high quality thermal paste:
Idle temp of CPU1, CPU2, and GPU - 77 degrees (F)
Heatsink temp - 84 degrees (F)
Running temp with adobe CS4, youtube, and typing this message - 103 degrees (F)
Pretty amazing if you ask me!
Before I applied the thermal paste my Macbook took at least a minute to start up with a fresh OS install, now it only takes about 15 seconds! I have not heard the fan spin up and go crazy since! And I can't even explain to you how much fast it is now!
This does prove that Random shutdown syndrome (RSS) is caused ONLY by your GPU over heating due to old thermal paste between the chips and heatsink! A design flaw by Apple? probably not because thermal paste will crack and dry over time.
This also proves that energy conversion to data in the chips can decrease because of over heating, causing the computer performance to dramatically drop!
So before you take your out-of-warranty macbook to Apple or a repair shop, see what your internal temp readings are and try to replicate the problem with over heating your CPU/GPU! This was a 10 minute fix! I am still amazed at how much faster everything is, and haven't had a random shutdown since! I hope this helps alot of people that think they are out of luck and have to pay to get it fixed!

I too have this problem as well and it has been getting worse lately, I don't know what to do anymore. Here is a little info about my macbookPro. I have the late 2008 unibody model, i bought it in late 2009 Refurbished from Apple. Recently my mac has been turning off out of nowhere. I may be doing something and all of a sudden it just shuts off, it usually happens faster when i start to open up more programs like Photoshop or Final Cut Pro. My mac is out of warranty now and i dont know how much apple is going to charge me to fix it. i mean they want 50 bucks just to talk to them on the phone (ridiculous if you ask me)!.

Mega 180. Randomly shutdown.

Anyone ever have this issue? The meda 180 just randomly shutdown. The light stayed on for 'PC', and the cpu fans were spinning, but the cdrom and hdd powered down, as well as there was no video. Nothing was running other than winXP, and it wasn't any hotter than normal. upon trying to boot it back up, it would sit and do nothing. i reset the cmos, and it booted again, but... odd.
amd barton 2500
corsair 2700 256mb x1 (sad, i know)
wd 120gb jb
random brand dvd 16x
mega 180, newly flashed bios
Also, while we're on the subject, the system takes forever and a year to detect ide drives. jumpers are right, and they are new units that work fine in different machines.
--> fix: me and a friend were talking. we decide the only thing I hadn't tried was changing out the jumpers themselves. to our humor, and my delight, switching the jumpers out for some newer ones laying around (same type of jumper, mind you) and the issue with ide drives taking forever to detect is fixed. however, I am still at a loss for the random shutdown..

oi, and when I have cdrom before hdd-0 in the boot priority, it will not boot unless there is a cd in the drive. boot other device is enabled... shouldn't it be cycling to the second boot device when the cd fails..? quit an annoyance.

Damages following 'Random Shutdown'

My MacBook has gone down with the dreaded RSS as well now. I was able to get it going again for a while by zapping the PRAM and by pressing power-on bottom for 5 secs (both needed). Until the next unsceduled shutdown...
I notice that a number of people choose to keep their MacBook running using similar methods rather than handing it in for repair, as they have little faith in Apple knowing how to solve the issue any longer. Too many logic-boards replaced to no avail!
My question is whether other components in the MacBook might be damaged by continued use? These cycles of irregular shutdown and forced start-up appear somewhat 'unhealthy' to me. An example: Some people have reported that the disktool find errors on the harddisc following RSS, which has even led them to postulate that 'fixing these solves the problem' (sic). In my case, it does not sound like the computer shuts the harddisc properly down during a random shutdown - also the process is much too fast.
What's the general opinion in this forum???
MacBook Mac OS X (10.4.7) Broken with RSS

I would like you to explain excactly what you think
the logic board is and what it does in your computer.
Thanks!
It's the "heart" of the computer that runs the operating system. Below is a logic board diagram.
As far as the hard drive goes, it's true that shutting a computer off abruptly can cause severe hard drive damage, but I find it very odd that I have not heard of one person with RSD having a hard drive problem. Even more strange, after all the shutdowns I had with my MacBook, I ran Tech Tool Pro and didn't find any directory structure damage.
Don't worry, be happy!

X220 - Random shutdown

My X220 is running Windows 7 Enterprise Edition 32 bit. I have updated to the 1.21 version of the BIOS.
I have a 128 GB SSD,
I am still experiencing random shutdowns under these circumstances:
1. Only when connected to AC power. I am using 65W standard AC/DC adapter.
2, Has been connected to the LAN always when it happens
I have re-configured my computer: Will come back with results.
1. I did upggrade BIOS to 1.21
2. I have now reduced the System Performance settiung in Power Manaher from a value of "Maximum Turbo" to "Turbo".
Kommer tillbaka med findings.

Grrrr.. while writing this entry - the computer made the random shutdown AGAIN (now using another machine). Lenovo - can you PLEASE make at least ONE Thinkpad with IBM quality....
Anyway .. here goes...
Bought an X220 i7 a few months back.
Data:
Model: 4291-36G
OS: Windows7 64bit (shipped with unit) + dual booting Ubuntu Linux 10.10 (64bit)
On BOTH Windows AND Linux these random shutdowns started to happen during the last week - with no change in my usage pattern (software development, browsing, email, etc. - under both linux and windows).
The most strange part is that the behavior feels like someone is pushing/holding the power key at random times (anything from 5 to 20 minutes after boot) - because windows goes to "fast sleep" and linux pops up the shutdown/sleep selector when it happens.
I just updated to the 1.21 bios (using a stand-alone CD from ISO).. luckily it didn't reboot while flashing...
This DID NOT FIX THE PROBLEM (I am not sure what bios was there before).
This really smells like a HW issue.
NOTE: Temperature monitors say that the CPU is well under critical - so that doesn't seem to be the issue.
My guess is:
1. faulty motherboard (sending the power off event.. or other)
2. could it be related to the fingerprint reader? - I know it's a long shot - but every time it has been initiated, I think my palms have rested, touching the reader as well as putting a light pressure everywhere else on the palm rest (just trying to help you to troubleshoot the design flaw - it's still a HW issue ;-))
Lenovo - I have 3 years on-site support on it... how do I get a new unit ASAP (I live in Denmark)? Can I just move the HDD to the new machine (I remember that Win7 may have some annoying copy protection linking machine, HDD and OS)?
br
Lars
PS Lenovo - as I wrote in the beginning of this post... I have NEVER EVER EVER EVER (well, you get the picture) had ANY problems with this back when ThinkPads were done by IBM. Can you please start making some machines that are as stable as those? So far, I have been the Proud owner of an X31, T41p, T21 and many more... and *not so proud owner of* T61p and now X220 - both seem pretty flawed - and I seem to remember an IBM internal stating they had to send 1/2 a shipment of T61's back because of serious problems with design, construction, etc...
PPS I know I was a bit evil above... but still think that premium price should deliver premium product.

Macbook problems, hard drive crash, random shutdown, freezes

I bought my macbook used a few months ago, and it worked flawlessly until about 3 weeks ago. The system started freezing and not booting (getting folder icon instead of apple at startup). I ran drive setup and tried to repair the drive, but this did not fix the problem. DiskWarrior also could not fix it. I pulled the drive and installed a new hard drive, as I wanted a larger capacity anyways. All my problems appeared fixed for about two weeks, then similar problems began occurring. I backed up all the files I needed to an external firewire drive and attempted to reformat the new internal drive. Drive Setup says it can not reformat the drive - can't mount it and if it does, the drive disappears while in the process of formatting. I pulled the new drive and am having it replaced under warranty. I am using the firewire drive to run my computer, and this seemed to work fine for a day or two until the computer just started shutting down with no warning. Everything goes black, including the little light on the front of the computer. I have to hold down the power button for 10 seconds before it lets me start the computer back up. I had read this may be a memory issue, so I ran memtest and it says the memory is fine (I need to do it in single user mode still, however). I also tried pulling both sticks of ram. They are both 1GB crucial memory. I put each stick in by itself and tried it in both slots and was able to reproduce the shutdown issue with any ram configuration of either stick.
After all this, I realized the firewire drive was only running 10.5, so I updated all the software through software update, and it is now running 10.5.2. It seems to be working better as I have not experienced a random shutdown yet, but I'm anticipating it may start back up soon. Today, however I experienced a different problem - the screen froze on me and the only way to get anything to happen was to force a shutdown with them power button. It's restarted and seems to be working fine again for now.
I've run some logs and here's some things I've found:
When the latest freeze happened, I got this repeated over 100 times:
Apr 29 11:04:31 jon-turners-macbook quicklookd[536]: CGContextClosePath: no current point.
I've also seen this:
Apr 29 11:18:19 jon-turners-macbook kernel[0]: Previous Shutdown Cause: 3
Apr 29 11:18:19 jon-turners-macbook kernel[0]: GFX0: family specific matching fails
Apr 25 19:19:50 localhost kernel[0]: hi mem tramps at 0xffe00000
Should there be anything else I can check? I would run Apple Hardware Utilities, but I don't have the original disks, just the Leopard installer. I have Disk Warrior, but it seems strange this would happen with multiple systems and drives. I'd like to get Techtool Pro, but haven't had the money/time to order it yet.

Thanks for the replies!
Yeah, I think it's the HDD. I was just worried that the RAM was bad and corrupted the HDD or something, but given the symptoms I think you guys are right. Ordered a 7200RPM 320GB HDD off Amazon Prime...will be here tomorrow
I'll post how it goes after I finish installing it. I'm backing up as I type.
I wonder if I can fix the ir port and the sleep indicator light when I install the hard-drive. The sleep indicator light never turns off. It stays on as long as my computer is on, only turns off when I shut it down.

K9N Platinum: CPU upgrade = Random shutdowns..

I just installed a new AMD Athlon 64 X2 3800+ EE in my MSI K9N Platinum motherboard (MS-7250 v1.0, the 070 model according to the box). I had updated the BIOS to version 1.7 before installing the CPU. Anyhow, I got the CPU installed and it seemed to be running fine. Until I started playing my games. Upon playing fifteen (!!!) minutes of Day of Defeat, the system completely turned off. COMPLETELY. No error messages. I check core temp's log to make sure the CPU wasnt overheating; it wasnt. The max temp was 38C on one of the cores. Just to make sure the CPU wasnt the problem, I ran two instances of prime95 for 5 hours and there were no calculation errors whatsoever. I also ran 3-4 loops of SuperPi, using the 32M test. No errors.
I have come to the conclusion that it must be the motherboard, and possibly it does not like the CPU. Or else it is having the same random shutdown problems as many other K9N Platinum/Ultra boards are experiencing. From what i have read, this issue only relates to boards that are 040, 050, or 060 models. I have a 070 model, and I AM GETTING THIS PROBLEM!!
Help!!!
Full specs:
MSI K9N Platinum MS7250 V1.0, BIOS 1.7, model 070
AMD Athlon 64 X2 3800+ EE (old CPU: AMD Athlon 64 3500+; had no issues with the 3500+) vcore: 1.225
1 GB OCZ Platinum DDR2-800, 5-5-5-15, 2.1v
eVGA GeForce 7800GT videocard with Zalman VF900, 490/1220
Hitachi Deskstar 7K80 SATA HDD
LITE-ON DVD-ROM drive
Floppy drive
3x 80mm fans, 1 cold cathode
Antec Truepower 430 watt PSU, dual +12v @ 17A a piece.
Any ideas?

well, i know that ACPI has to do with power saving features.
http://en.wikipedia.org/wiki/ACPI
and HPET also has something to do with CPUs
http://en.wikipedia.org/wiki/HPET
and MCP55 is the nortbridge.
so i suppose i can conclude that it protects from overvoltage or promotes more power-saving? i dunno i really dont care as long as my PC works now,

White Macbook 2006 random shutdown solved removed cpu heatsink and more

I picked up a cheap macbook from a secondhand retailer for $300 and it regularly shutdown, froze, restarted as well as the grey kernel panic screen completely random no real pattern. I set about trying to solve the problem swapping ram and hard drive with my identical 2006 macbook (which I had similar problems with last year, fixed that one with a new battery connector cable). The ram and hard drive made no difference so I downloaded istat menus to see if any combination of cpu voltage, current and temperature were causing the random shutdowns. It seemed when the temperature reached certain values the computer would shutdown or freeze(around 30 to 50 degrees). I'd read on other forums about faulty cpu temperature diodes so I reapplied heatsink compound to the cpu heatsink and checked all the wiring for shorts but nothing seemed to solve the problem. I was ready to retire the computer and use it for spares for my other macbook when needed but I pulled the keyboard off one more time and tried something completely radical. This fix requires some forward planning and software installation but it has completely solved my Random shutdowns completely.
for instructions see my next post *Fix for random shutdowns white macbook*

Ok this is not for the non technical person but it is quite a simple process with the right instructions.
This first step is very important install the software coolbook($10) and fan control (Free)( not smc fan control). Set up coolbook to operate the cpu at the lowest speed and voltage for both power adapter and battery(1002MHz and .95Volts). Remove the keyboard to access the computer logic board (instructions can be found at iFixit). Remove the four screws and two connectors holding the heatsink to the logicboard and gently lift the heatsink out (very important that you leave the fan screwed in and connected). Close the computer back up if you wish to test just gently connect the keyboard and loosly sit the keyboard back in. Restart and reset the pram immediately. Let the computer boot up and then open system preferences and configure Fan Control to your liking. So far no random shutdowns for over a week (was getting many a day previously.

New system, random shutdowns w/ infinite reboot-cycle afterwards
