OSX Lion running, but video display frozen. Safe mode hangs
When I started my Mac Pro (early 2008) this A.M. the video display froze (pin wheel stopped spinning), but OSX booted successfully (I could access shared drives from another computer on the network). I also noted a small black rectangle at the top left of the screen. I tried booting into safe mode, but it hung at about the 25% point as shown on the progress bar. The pinwheel was still spinning however. Power cycled the computer, but the results were the same. Did all of the above several times with the same results. I booted to a known good Super Duper clone, but it also failed. I'm guessing the video card has failed, but no way to verify this. Anything else I can try?
Referring again to the article, only Macs that shipped with 10.7 can run the AHT from the Internet. A 2008 Mac Pro would have shipped with 10.5. If you have a 10.4 disc, it came with an older Mac and won't work. If you can't find the Applications disc that came with the MP, then you can't run the AHT.
In that case, I suggest you try booting from the recovery partition. If you can do that, run Disk Utility, repair the startup volume, and reinstall Lion. Probably this won't help, but you will then have ruled out everything except a hardware failure, which is what I think you have.

My iMac won't start up, or wake from sleep. I've tried everything, except for reinstalling the SO-DIMM memory modules. Still, my iMac will not wake up. Turning it on, you can hear the fan run, but the display stays dark. Any ideas what to do? Thanks!
Mac doesn't boot
Can you hear the fans and hard drive and see the white boot screen? Flashing question mark? The circle just runs and nothing happens? Only black screen and nothing else? These can be very helpful to diagnose the source of the problem. [1]
Flashing question mark [2]: This is usually a sign of a failed hard drive. This indicates that boot up volume can not be found.
Black screen: This is usually a sign of a failed logic board. There is no single reason for this and this may be caused by failed GPU, screen, CPU or RAM.
Circle of death/no circle/blue screen: This is usually a sign of a hard drive failure. This may NOT be a dead hard drive, just broken permissions or something
Gray screen/Apple logo/spinning gear or globe/prohibitory sign/folder with flashing question mark [3]: This could be a sign of faulty hardware but more likely a software issue, i.e. broken permissions, failed software update, etc.
[edit]
What to do
First, hold down the option key (also known as the alt key) just after you've pressed the power button. This should show all the available options to boot from, so if you have Windows installed through Bootcamp or a disk in your SuperDrive, you should be able to see them along with your OS X drive/partition. Select the OS X partition with arrow keys and press enter. Startup key combinations
If that doesn't help continue doing the steps from below:
1. SMC reset [4]. Shut down and unplug all cables including power cord for at least 30 seconds and then plug in power cord and keyboard/mouse.
2. PRAM reset [5]. Hold down option, command, P and R while booting. Start it when you hear the sound and don't let go before it reboots.
3. Safe boot [6]. Hold down shift while booting to boot into safe mode. If this works, open Disk Utility from Utilities and repair your permissions and verify the disk
4. Hardware test [7]. Insert the install disk (disk 1 in Mac which shipped with OS X 10.5.4 or earlier, disk 2 if shipped with OS X 10.5.5 or newer) and hold down "D" before the grey boot screen opens. Follow on screen instructions
5. Boot from install disk. Boot from the disk that came with your Mac. Hold C while booting. Select Disk Utility from top bar and repair permissions and verify the disk. Reboot normally and see if it works now.
6. Boot from another Mac (Firewire target disk mode). Connect the machines with a Firewire cable. Power on your Mac and press T. Select the other Mac's hard drive. Download the current OS X combo update. Run the combo update installer and select the drive that won't boot as the destination.
7. "Repair" OS X. Boot from the install disk as in point 5. and reinstall OS X. This should NOT erase any data, just replaces the system files which may have caused your booting problem. Now install the latest combo update for OS X and repair permissions on your drive with Disk Utility.
7.1. Install OS X into an external hard drive and then boot from it [8] and try to copy your data from the hard drive before proceeding. If you have done a backup recently, you don't have to do this.
8. Restore OS X from Time Machine backup. Boot from the disk that came with your Mac and choose the Time Machine restore option. This step will lose any changes made since your last backup but the system and your data will be put back to exactly as it was on that date.
8.1 Reinstall OS X. Boot from the install disk as in point 5. and select Disk Utility again. Now erase the whole hard drive and install OS X again. If you had a Time Machine backup and step 7 worked you don't have to do this. -
hello
I can't reinstall osx lion from internet, and display a message"cannot find installation information ,please contact applecare, what should i do?
thanksI'm no Lion expert, but I believe you can boot from the Recovery partition by pressing the Command and R keys on startup, then reinstall.

If I open a movie file (appears to be any type - .mov, m4v, mv4) it displays on the desktop, but when clicked, the Mac reverts to another open application (immediately UNDER to point of the mouse click) and not the displayed movie file. It appears the screen mapping is flawed...
Anyone else have this problem? (does not appear to be a problem with QT7) Running OSX Lion 10.7.3 and QT Player 10.1 (501.8) - all most current as far as I can tell...Yes, same problem. The active clickable area appears to be shifted down and to the right as if it is the shadow mask (to make it look like layers in the display) that is responding. Means you can't move the control palette to the top of the window (to not block security video with time track at bottom) or even close the window. The X in the bubble appears when moused over but the click goes through it.
Most obvious if you open more than one movie at a time and they cascade. You can't get at the ones underneath until a few down the stack and it gets an upper wrong one.
Who's testing these things?
For comparison testing to recreate problem: Mac Pro (System Information has also been dumbed down from System Profiler, push System Report for the useful stuff) with an ATI Radeon HD 5770 driving two displays.
Also viewing desktop of another computer on the network is slower and, for instance in World of Warcraft, the hand pointer flickers.
And finder windows can't be narrowed as much any more to show only a list of file names for drag and drop sorting.
Was hoping that by 10.7.3, it would be safe to jump, since several posts told me how to Terminal > networksetup -setv6off Ethernet to fix iTunes streaming to expresses and other dumb bugs. -
Disable Lion video driver, without Safe Mode?
We have an old 2.0 ghz 17" Intel iMac with Lion installed, which is used exclusively for managing iPads. The iMac has no other purpose in life, and is only turned on to download iPad software updates and run Apple Configurator.
This summer the iMac suddenly stopped working. It shows a random broken image when it boots and the system eventually freezes with a forever-spinning cursor. Apparently this is due to the soldered-in 3D graphics accelerator developing a problem, and which seems endemic to this model of Intel iMac.
However, I discovered that Recovery mode works fine...
And I can reinstall Lion...
But after two attempts to reinstall Lion, that doesn't help at all.
I then discovered that Safe Mode also works fine, and then that Safe Mode allows me to boot a backup of the previous configuration before reinstalling Lion. I am in fact typing this message using Safe Mode on the iMac.
So the iMac works okay in Safe Mode, and I see it is possible to permanently enable Safe Mode...
sudo nvram boot-args="-x"
However safe mode tends to degrade lots of other system capabilities also, such as no sound, plug-in USB flash drives don't work, etc.
Is there a way to just disable the video acceleration driver alone, but load everything else normally?I found the solution I was looking for.
The iMac works fine (with safe mode disabled), if I just disable the ATI Radeon X1000 video driver.
This can be done by either deleting this file or moving it to another folder:
/System/Library/Extensions/ATIRadeonX1000.kext

From what I'm reading in these forums, this is likely an issue due to some 3rd party software / kernal conflict. I am going to run a diagnostic and perhaps someone here can help me evaluate the results and determine what software must be removed.
It's hard to describe what I'm seeing on screen. I've never seen anything like it. I get a number of lines that begin at the top left of my screen, about at the apple icon, and they spread out in a triangular pattern from left to right, top to bottom across my screen, while the entire screen flickers uncontrollably. I realize that iMacs from this era have screen issues, but since I can boot fine in safe mode, this can't be a hardware issue.
Any assistance is greatly appreciated!1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with "Model Identifier." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.

Installed Premiere Pro CS4 but video display does not work?
I just got my copy of CS$. After installing Premiere I found two things that seem very wrong:
1) video display does not work, not even the little playback viewer next to improted film clips located on the project / sequence window. Audio works fine.
2) the UI is way too slow for my big beefy system.
My pc is a dual boot Vista-32 and XP system with 4GB of memory installed and nvidia geforce 280 graphics board with plenty of GPU power. The CS4 is installed on the Vista-32 partition. My windows XP partition on the same PC with Premiere CS2 works great and real fast.
Any ideas how to solve this CS4 install issue?
RonI would like to thank Dan, Hunt, and Haram:
The problem is now very clear to me. The problem only shows up with video footage imported into PP CS4 encoded with "MS Video 1" codec. So this seems to be a bug. The codec is very clearly called out and supported within various menues but video with this codec just will not play in any monitor or preview window. In addition the entire product looks horrible with respect to performance while PP CS4 trys its best to play the video. Audio will start playing after about 30 seconds. And once in awhile part of video shows up at the wrong magnification before blanking out again.
My suggestion to the Adobe team: fix the bug and add some sample footage to the next release so new installations can test their systems with known footage.
My PC is brand new with the following "beefy" components:

My Macbook Pro keeps freezing/crashing after a few seconds of use, but works fine in safe mode.
I've researched this extensively, but I haven't been able to solve my problem yet.
It started completely out of the blue with a kernel panic, where my screen seemed to malfunction and I got the kernel panic message (but I could hardly read it because of distorted graphics). I forced my laptop to shut down, but every time I rebooted and used it again it would completely freeze after a while (the amount of time varied, it has lasted from a few seconds to a couple of hours). What happens essentially is that the cursor and entire OS freezes, and I'm unable to click on anything or use the keyboard. The fans start working full speed and the only thing I can do is force the laptop to shut down.
At first I thought it was a Chrome problem because it only happened after I opened the browser. After uninstalling it, the laptop seemed to work fine for a couple of hours, but then it froze again while I was using Safari. Ever since it has been functioning normally for smaller and smaller time periods before freezing again. I've tried reinstalling Snow Leopard OS from the original disc and then downloading all software updates, but the problem continues. I've also tried doing a hardware test by pressing D as the computer starts up, but for some reason it doesn't work.
The laptop, including Chrome and Safari, works fine in safe mode.
I'm sorry I don't know what specific information to give you about my laptop/OS, but please ask anything you need to know. I'd greatly appreciate any help — I'm panicking because I fly to England tomorrow morning to start university and I really don't want to go without a laptop for 2 weeks while it's getting fixed!Thanks for your reply!

Early Imac 20" freezes on regular mode but works fine in safe mode, any ideas?
Have a early 2006 Imac 20" that won't run in normal mode; freezes within minutes. Run fine in safe mode, but safe mode won't play sound or allow exterior inputs. In high fan state, don't know the name of the mode, but you hold the power button while plugging in power cord, the machine also runs relatively fine. The machines been glitzy for years, developed the lines/colour patterns that's been mentioned in other forms/threads, but it still ran programs. Took it to apple and they said the board is the issue and my machine is obsolete. Fine, I just want to understand why it will run perfectly in safe mode; no lines, no freezing, all programs running...but won't last minutes in regular mode. Also, if anyone has a way to play music...in bluetooth or appletv in safe mode, let me know.
Thanks.Most of thee skinny on that...
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Premiere pro crashes on playback but works fine in safe mode
hey i installed premiere cs5 and updated with the latest update and when i playback footage the program crashes, i've tried safe mode and the program works fine & the video does wonderful and i can edit no problem, but of course there'e no sound so i can't edit like that, any suggestions?
System specs: windows 7 professional 64 bit
processor: intel(R) core(TM) i7 cpu 860 @ 2.80GHz 2.79 GHz
intalled ram: 8 GB
op sys: 64 bit
i get this
problem event name: APPCRASH
application name: adobe premiere pro.exe
application version: 5.0.1.0
application timestamp: 4bf119d2
fault module name: display.dll
and the list goes on...
if anybody has a fix please let me know thanksHave you updated your video driver? If not, that could well be the issue. Go to the nVidia, or ATI Web site, and get the latest version for your video card.
Now, something else to consider is that during boot up, something is loading, that is getting in the way. This ARTICLE will give you tips. In Safe Mode, those problem programs and processes are not loaded.
Good luck,

Lion 10.7 Only Boots in Safe Mode. Is This a Hardware or Software Issue?
Hi. On my iMac late 2009 i7 8GB bought last March only. I reinstalled Lion (I didn't erase the whole disk because I have Boot Camp Windows and I have filed there) and it can only boot in safe mode if I use the Mac's built-in EFI bootloader (where you have to press option on restart) menu then press shift after choosing the iMac OS X hardisk. I've been trying to fix it for around 4 days now today. I'm tempted to take it to the authorized Mac shop but that could take weeks to months in our country. If I let it boot normally, it would seem to have a kernel panic and would stop at the white/gray screen. Verbose mode showed that is stopped at something 10 of these like: nstat fail.
Is this a GPU hardware problem, specifically the 3D element of this 4850M GPU? I'd like to do load each kext, each extension manually but I can't find them in Lion. When I use the Lion DVD or the Lion Recovery partition, it's very sluggish, every click and process takes 20 seconds to minutes. If I try to boot in Linux, Snow Leopard DVD or Snow Leopard external hardisk, there seems to be a kernel panic. It's either just a black screen or a garbled screen.
I want to erase/format the iMac's hardisk but in Safe Mode, it can't be mounted even if I use Disk Utility. If only there's a way to force it to mount, I can save some Windows 7 file to one of my external hardisk or flash drive. Does anyone know of an app or program that can mount NTFS files on Lion's Safe mode?
If it's a Lion bug, has Lion somehow corrupted the Mac's built-in (hardware not the EFI partition in the hardisk) EFI or somehow corrupted the Mac or GPU's ROM? Could it be a new OS X virus? Should I then perform in Safe Mode to flash the GPU ROM and the Mac's ROM again (I have the latest)?
Do you think if I erased the whole drive, reinstalled it again with either Snow Leopard (assuming it doesn't boot into a garbled screen) or Lion things will go back to normal?
Has anyone experienced something like this? What was the culprit (was it a hardware or software issue) and what was the solution?
Gbu.Hi thanks for all the concern and replies. I've tried all that.
I had just got it back from the shop last Friday. It was there for around two weeks. It was a faulty GPU (when you see garbled display that's consisten when booting it the GPU). I have a strong feeling it's related to the Lion install 10.7 or 10.7.1 and may be similar to reports of Mac laptops overheating. It's good the GPU is removable, it might have taken 3 week or a month if it had been the whole board.
It's a blessing in disguise though as with all or most cases because I also got to have the LCD replaced for excessive backlight bleeding (in my opinion), the dead pixel from the previous LCD isn't there anymore (though under the glass there're some smudges but nothing crucial). The backlight bleeding is still the same though in my opinion but at least it's new.
It's a great thing I bought Applecare. I didn't buy it for the iPhone because that's more durable (my iPhone 3G's 3 years old now and it's still solid. Although there are scratches and a crack at the back at the bottom, got sqeezed under the table I think when I sat). I think Applecare is a good recommend for things that get hot like desktop and laptop Macs(are the iOS considered Macs btw?) which are twice or thrice the price of iOS devices.

Desktop stuck at black screen with cursor in normal mode but boots fine in safe mode after updates.
After running some updates the other night my laptop stopped loading the desktop and just gets stuck at a black screen with a cursor after I log in to the user account. The only thing I can do from there is do ctrl+alt+delete, then log off or restart.
I can't open up task manager. I tried creating another account in safe mode thinking there was an issue with the account but I still have the same issue. In event viewer I have two warnings one is
event 6000 winlogon, The winlogon notification subscriber <GP Client> was unable to handle the notification event

besides restoring to factory settings?Hi,
We may try to reinstall Windows 7 Service Pack 1 for a test.
In addition, let us perform the following steps.
1. Click Start, Run, type lusrmgr.msc then ENTER.
2. Select Groups in the left pane.
3. Double-click Users in the right pane.
4. Click Add, and then click Locations. Scroll to the top of the Locations dialog and select the local computer name, then click OK.
5. In the Enter the object names to select field, type Interactive; Authenticated Users (separated by a semi-colon). Then click OK.
6. Restart the computer.
Or we can run the following commands from a command prompt:
Net localgroup Users Interactive /add
Net localgroup Users "Authenticated Users" /add

Snow leopard freezes but works fine in safe mode
I have been using snow leoprad and it hangs after login to the system (from the first one/two minutes). But it works well in safe mode . So far the things I have tried are - repair the disk permissions, verify the disk , created a new user account etc. But I'm not getting a soluion. Please help!!
Hmm, that's not good. Running out of "moving parts".
No third party add ons but works in safe mode only! Here's the apple article on what happens during a safe boot.
Mac OS X: What is Safe Boot, Safe Mode?
Since third party stuff is rulled out you would think it would be one of the other things mentioned that may be corrupted. For example, /System/Library/Fonts, font cache. In other words, font related.
Not sure what to suggest at the moment and it's my bed time.
Maybe look at OnyX (Maintenance, Rebuild) and rebuild the dyld shared cache and look at other stuff in OnyX that might need rebulding (Cleaning, Fonts, delete font caches). -
Will not boot normally, but will boot into Safe Mode... what now?
Hey y'all, I've got an iBook G4—purchased in 2003—that's had its hard drive replaced (due to the OE one failing) and that's on its second battery (which will need replacing soon unless I can't get this resolved, then it's new computer time... ugh).
Last night I left it open and on and probably had a couple of sites open in tabs in Safari, as well as Mail and iChat open (Preview might've been open, too).
When I went back to it this morning it wouldn't come off the black screen (I don't have it set to sleep), and I thought it was because it's dry here and I must've discharged into it through the trackpad (though I've always felt it before), which freezes it, a problem that's happened before and that's normally resolved with a restart. Confirmed it was, indeed, frozen by turning the number lock on and off (which turns the light for it at the top of the keyboard on and off).
Powered it down by holding the power button. On restart it wouldn't go beyond the black screen. Tried it a couple of times, same problem. Things were pretty warm, so I let it sit for a while. Went back to it and it would freeze on the gray apple screen with the progress "gear" freezing after a few seconds of whirling about. Managed to get to the UN/PW screen once, but it froze after entering my UN and PW. Now it freezes on the apple/gear screen every time.
I used the Hardware Test CD to check things and all the hardware tests showed up fine. Booted it into Safe Mode and ran Cocktail. Rebooted, no joy.
Booted again into Safe Mode and backed it up onto an external HDD using CCC. I had done a clone a few weeks ago, but I wanted my most recent emails, etc.
Used Disk Utility to repair permissions. No change. Attempted to boot from my cloned disk image. No go. Repaired some permissions on that drive and tried again. No joy.
The thing "works" in Safe Mode, but I cannot get it to boot into things normally.
Seeing as it was online, is it possible that I picked up some corrupted font that's causing these problems? Got that idea from other stuff I've read online regarding iBook G4 start-up issues and this: http://support.apple.com/kb/HT1564?viewlocale=en_US
Any other ideas?Gents, truly, thank you.
In safe mode I couldn't disable the Airport card as it was already off and the hardware was "not found". No biggy. I simply pulled it. Booted up normally without a problem several times.
I swapped in a known-good Airport card from another iBook G4 and put this one's in that iBook. That computer wouldn't start and this one started up no problem (and I'm posting from it).
Weird that it would go bad like that, but it did. It's nice to know what the problem is and that the fix is easy. I'm glad I didn't go through any restore or wipe and install procedures.
So, again... THANK YOU! -
Laptop freezes in normal mode but works fine in safe mode
Hi
I have a Toshiba satellite M45 which recently started to freeze randomly. I have checked my hard drive with Hitachi drive fitness test and it passed all the tests. I have changed my ram from another working computer but the problem persists. Today I formatted my harddrive and had a fresh installation of windows but still getting the same problem. It seems that hard disk just turns off as it gives a ticking sound you normally hear when the computer is powered off. I rebooted the machine in safe mode and it works fine every time.
I would really appreciate if some one who faced the same problem can share there experience ??
Cheers
MikeIt appears that some device whose driver does not load in Safe Mode malfunctions.
If this occurs before loading any drivers for added devices, then you'll need service.
