Will Not Boot from Install Disc & 4SNS/1/40000000: TG0D - Thermal Sensor?

*Will Not Boot from Install Disc*
I used the "option key" approach with the gray start up disk. At first it ejected the start up disk. Then I nudged the disk back in the machine and it showed on the screen as an option. I clicked on the start up disk image and it finally loaded.
But, it won't accept the start up disk when holding down the "C" key at restart.
*4SNS/1/40000000: TG0D*
I did an Apple Hardware Test and received the following diagnostic:
Version: 3A121
Test Suite: Extended Test
Loop Count: 2
Result: Failed
Failure code: 4SNS/1/40000000: TG0D
*Thermal Sensor*
A search for the failure code 4SNS/1/40000000: TG0D brought up an Apple Discussion topic entry stating: That error code indicates a problem with a thermal sensor. It could be not working or possibly not connected. You will need to take it to Apple for repair.
Would a thermal sensor have anything to do with it not starting up when holding down the "C" key at restart? What are thermal sensor problem symptoms?
*User File Folder Opened Up*
The machine also starts up with my user file folder opened up rather than with a blank screen as it normally should
I completed a DiskWarrior rebuild on the disk and verify disk shows it is fine.
Any suggestions on what to do next with these issues?

The answer was in your post: "You will need to take it to Apple for repair."

Restart into Mac OS X 10.7, open the root level of the Mac OS X 10.5 partition, choose Go to Folder from the Finder's Go menu, provide private/etc/ as the path, and drag the backup copies of those files into that folder. If needed, the default permissions for them are system with read and write access, wheel with read only access, and everyone with read only access.

2005 mac mini on OSX leopard will not boot up from firewire disk

I have an old mac mini that my son still uses and the super dirve does not work any more. But now the main hard disk needs to some attention from Disk Utility. So I need to boot up from the Leopard install DVD. But of course the DVD dirve does not work so how to do this? I have tried to create a bootable disk by restoring the install DVD to a partition on a firewire drive and this is seen as a bootable drive by my 2008 iMac, but not by the Mac Mini. So is it possible to boot up rom a irewire drive? USB doesn't work either

Which Tiger Install DVD do you have...?
1. I think that, that model originally came with 10.4.10 and so you will need either the original 10.4.10 install disc or a later retail (Leopard or Snow Leopard) upgrade DVD.
2. In addition, a new (HDD, Hybrid Drive or SSD) must first be Partitioned GUID Partition Table and Formatted Mac OS Extended (Journaled) before OS X can be installed.

Power mac G5 turns on but will not boot up

Hello,
I have the last power mac G5 quad core made before apple switched over to intel. I have not used he computer in about 3 month and it worked fine when I put it into storage but when I tried to turn it on today it will not boot up.
There is constantly a yellow light on near to where the RAM snaps in even when the computer is off. (this is the 3rd light up from the bottom and the only on that is on at this point)
When I press the power button a red light turns on for about one second. Next to this light are the words LED806 Checkstop and it is offset to the right of the other lights a little bit when looking into the side panel of the computer. This light also lights up briefly when I press the power button to turn off the computer.
After pressing the power button another red light turns on just above the yellow light that is always on and the screen is still black. Then the screen eventually turns grey with the apple logo as it normally looks except some of the pixels are off colored a bit in square patterns across the screen. When this happens a green light turns on just below the yellow light. Now there are three lights on all at once.
Next the screen briefly turns light blue and then a little darker shade of blue and the computer will not boot up or go any further than this point.
Can anybody tell me what is going on here and is there any way to fix this?
Is there any way to reset or reboot the computer this the install disk?

installed bootcamp on my mbp with snow leopard today,for the first time mac and windows both started with no problem ,but when i was trying to boot back into the mac again ,it did not boot and just got stuck at the process with turning wheel forever ,showing the apple logo and the turning wheel.
i did try to hold the option button and chose the mac partition ,but again i can not pass thru the turning wheel and apple logo.Does anybody know what the problem is and how can i go beyond this .
thanks.mike

Have you tried a safe mode boot yet?
Reboot to the OSX partition and hold the shift key down as soon as you hear the chime. You can release the shift when you see the spinning gear wheel.
yes,i did try that too.unfortunately ,hard drive seemed to be the source of the problem.just replaced the hard drive with a brand new one and put this one inside a usb enclosure that i have ,so tomorrow i will get a backup first and then format it again and keep it for the future.
thanks.mike

Mac Pro Processor heating and will not boot

Hi All
I have a 2009 Mac Pro with dual processors, this has been a great system until recently it started to shut itself down after around 20 minutes of use, I tracked this to a processsor getting too hot and shutting down. I air dusted the unit and replaced increased the fan speeds. Now the mac pro will not boot. As soon as I insert the power the motherboard flashes red and will not power up the system. Is there something I can do myself? Can I clear the mac bios? Any thoughts or advice would be appreaciated.
Cheers

thanks Hatter, I appreciate your advice.
The system is running 10.6.2, or was running.
I tried the SMC reset:
SMC Reset using "unplug, hold power for 5, release, plug in
SMC Reset using "unplug, hold power button, plug in, release
No change either way.
What happens is, watching with the case open, when I plug the power cord in and two red lights flash on the motherboard "CPU A" and CPU B". And nothing happens from there, no fans, nothing.
I wil try to remove the heatsink if I can find the right tool.
Do you have any other thoughts?

Mac has snow leopard and does not boot has grey screen

Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

Windows 8.1 Pro will not boot after installing iTunes 11.1.5.5

It's a little hard for me to accept that this is true, but the symptoms seem to be pointing the direction of the title of this thread. I have an all-in-one touch-screen Gateway computer that came with windows 7 (yeah, a win7 machine that came with touch, yeesh) and I put windows 8.1 pro 64-bit on it with a clean install (actually windows 8 was the clean install and then I did the free microsoft store upgrade to 8.1). It has 4GB of RAM and has a Pentium Dual Core cpu @ 2.2 Ghz. It was running fine with the previous version of iTunes, but as soon as I updated to iTunes 11.1.5.5 (and there may have been other apple things that updated too (ie quicktime of course), the computer prompted me for a reboot and froze during the reboot process (before it even shut down). Then it had trouble booting into windows. I ran startup repair to no avail and decided to do a sytem restore. My most recent restore point was from a few weeks back, before iTunes was even installed at all on the machine. I went back to that point and the machine worked fine again. Then I installed iTunes 11.1.5.5 and the same exact problem occurred - it froze while shutting down after the iTunes install and then would not boot into windows 8. I did another system restore and have not put iTunes back on. The system is working fine. I'm going to try to find out if there's a way to download older versions of iTunes, so that I can install it, but the bigger issue here is: Is this a legitimate bug/incompatibility with some hardware or software or driver that I have on this computer? I run a computer support business so I know my way around but I don't have time to troubleshoot this from scratch. Anyone else seeing this? Apple employees...a little help here? Any input?

let it sit for about 30 min and still got nothing
I then did a "hard shutdown(just pressed power button till it turned off the computer)"
That may not have been long enough. But a "hard shutdown" would definitely have been construed as a problem due to the update.
Asus apparently is a known problem case...

Windows 8.1 Pro not booting after install of Hyper V - ASUS z87 + intel 4670K

Hi,
I am running windows 8.1 pro on a intel 4670K 4th Gen Haswell CPU and ASUS z87 plus motherboard. 16gb of kingston hyperx ddr1600 memory.
I have enabled virtualisation technology in the bios. CPU has SLAT.... or Extended Page Table, as intel likes to refer to it.
When I install HyperV platform and management tools the computer configures and reboots
AFter reboot it brings up the blue window image and spinning circle of dots for a while then reboots. It does the same thing again and then reboots and goings into repair mode and asks me to do a system restore. It then restores to before they HyperV install.
I've tried turning off xHCI mode (i.e USB 3.0) in the bios as this seemed to be a known issue with some gigabyte boards. This did not rectify the issue
Updated to latest asus mainboard bios 1405. Same issue still occurs upon install of hyper V.
Automatic repair does not work and I have to restore from system restore point.
I performed a clean boot after installing the feature and it still couldnt boot to windows.. it just sits at windows logo and then restarts a few times and then launches the startup repair. Once the startup repair begins, the only way I can get into windows
is restoring to a system restore point from before the hyperv feature install.
Please see the following logs which may have further information:

I logged a job with asus support and their response was:
"Clear CMOS and ensure virtualisation technology is turned on in BIOS. If it still doesn't work, seek assistance from Microsoft"
Previously asked this question but took a while to get back to update with the logs and it was listed as Answered.
This issue is still existing and I'd appreciating any assistance.
