Issues with graphics ... force 'safe mode' graphics in normal mode?

Hi,
I have a late 2007 MBP with the ATI graphics chipset. Everything was working fine other than a few distorted screens at the very start... now I can only get in to safemode.
I can not get into the login window on normal and sometimes it flicks to a screwed up display with beachball (display b/w beachball is coloured) everything appears to work fine in safemode other than the obvious fact none of the other extensions are enabled (sound, wifi etc)
Is it possible to force the OS to load normally but without the accelerated graphics? When I turn on the computer it usually shows distored at the apple screen and then clears up to a grey screen and usually goes blue before failing at screwed screen + visible beachball.
I've reset the pram,
fixed permissions and everything else using applejack
removed refit
fsck -fy
I would try to do an archive and install but unfortunately the drive has died on this laptop. I did try to boot from a mac server using netboot / netinstall however I get the same issues as normal mode.
I just find it really frustrating that I can type here with net access in safeboot and use almost all I use this for anyway...
I also bought a external dvd drive with my mac mini server however the laptop does not seem to detect that.
Anyone with any thoughts? thanks

Is it possible to force the OS to load normally but without the accelerated graphics?
Not with this model. Some newer MBPs had both integrated graphics and a discreet graphics chipset, but not those having the NVIDEA 8600M GT chipset, which I suspect yours does.
There are defective NVIDEA 8600 chipsets in the Late 2007/Early 2008 MBPs and, if that it the source of your problems, there is no home remedy--the logic board must be replaced.
Fortunately, Apple has a program that covers this at no charge to you:
http://support.apple.com/kb/TS2377
I suggest you print out that page and take it with you; it seems some Apple Store employees and AASPs are not aware of the program. The techs have a special tester that quickly determines if the NVIDEA chipset has failed and the computer qualifies for the free logic board replacement. If that test fails to detect a bad graphics chipset, then something else is afoot.
The point is that, with your model, you need to eliminate the NVIDEA curse first before trying further diagnosis.
I would try to do an archive and install but unfortunately the drive has died on this laptop.
Try a cleaning disk. It's amazing how meay people here report being told by a tech teht the optical drive was dead but resurrected it with a simple cleaning

Boot issues with Win98. Safe Mode Boot only. Not all drives detected...

Hello guys! This is a great source of information and I've learned a TON browsing this place (on company time, hehe), but I've hit a road block that I can't maneuver around.
System Config
Neo K8T Neo Fisr mobo
Athlon64 3200+ CPU
1 Gig Kingston RAM
Ti4200 64 MB video card
520 Watt Antec Power Supply (after getting schooled by Bas's great posts on the importance of PSUs, I found out my lame-o 350 watt (!!!!) PSU, errr, ain't gonna quite cut it.)
Problem:
Windows98 won't boot all the way to normal mode. It only boots to safe mode. Apparently a driver issue?
Symptoms/Clues:
- Only detects my Western Digital harddrive (and only after some finegling)
- Wierdness with my 1.44 3.5" floppy (A:) drive. At first the BIOS would tell me the A: drive was there, regardless of whether it was plugged in. Then I plugged in the A: drive and Win98 in safe mode couldn't read from it. Right now, I don't have my A: drive connected and it's not in my Boot Order sequence (hard drive only for now).
- BIOS doesn't detect my new CD-ROM (SONY) drive at all. Note, this is a brand new drive that was NOT on my old system.
- I disabled the S.ATA controller. (This was confusing because there's an option to disable some SATA thing under an "Integrated Peripherals" menu. However, there's another setting to disable s SATA thing under a PCI Controller's menu. Seemed vague to me,, but then it's been a while since I've done this sort of thing.)
- I cleared the CMOS earlier because of wierdness were the system would hang on bootup and would ask me about starting a "Flash Recovery" process, upon which it would just sit there ( I left it running overnight once).
Call for help
Unfortunately I have no boot floppies, so I was hoping this was something I could fix without one, perhaps by changing some BIOS settings. Maybe it's a RealTek Boot Agent thing?
Any help is appreciated!

Im running win 98se with no real problems, and its doing so well that I still dont even feel like trying anything else..........
I'd say RE-clear your c-mos , using the jumper, and unplugging the power for 5 seconds..... then reset your bios settings.......Also, maybe just reinstall the via 4-in1 chipset drivers...... I remember fiddling with some bios setttings before, like the acpi by os or by bios etc.... that helped.....but its been awhile......The great thing about 98 is that you CAN tweak so much.......
You can reinstall over itself also, which can help redetect the hardware, yyou should always have the 98 files on the hard drive so you dont need the floppy or cd...... So many things you can try....... Resolve yourself to trying as many as possible , its fun when you get it right........... My prob. is that I never remember what I did to fix stuff heheheheh.......good luck
ps, the "flash recovery" thingy has to do with the realtek ethernet lan thingy....which you should disable in its bios.....I forgot how to get to it, I think F11 or something like that while it shows when you are booting....Then it will still ask when you boot, but wwont hang......

Issue with graphics tearing on thumb scroll in Flex 3

We are seeing some off issues with graphics (one using the charting package and the other using degrafa) tearing on thumb scrolling in a large Flex 3 app. It's very hard to reproduce on OSX with the latest versions of Safari and Firefox, but it shows almost immediately when you run the app on Windows or Linux (regardless of the browser). I took one of the pieces out of the app and put it into a very simple testbed app and can't get the problem to show on Windows (i was hoping to isolate the issue in a smaller test case, but no such luck).
So, ii've got a few idea's on how to work around the issue, but i was wondering if anyone else has seen this type of problem before?
Problem:
     - graphics tear on thumb scroll
     - doesn't happen if you click in the track or use the arrows
     - one view is using the charting package, the other view is using degrafa
Thanks for any comments or suggestions...
Richard

SOLUTION: changed wmode from "opaque" to "window" in the jsp serving as the wrapper for the app's main swf...
Here's the reference we used to determine the proper setting for wmode;

Z68A-GD55(G3) BIOS Issue With Graphics Card

I have been having a strange issue with the BIOS. When I use my graphics card it appears all glitched. (see below picture) When the graphics card is removed it appears fine using onboard graphics.
Processor: Intel Core i7 2600k
RAM: 2x4GB Corsair Vengeance 1600MHz
Graphics Card: MSI HD 6950 2GB Twin Frozr III
PSU: Corsair TX850M
Hard Drive: ADATA 60GB SSD

What screen connection are you using ? Can you try a normal d-Sub connection to start with ?
Also suggest you do a CMOS clear after the connection.
What did you use before this card and did you clean all old drivers before installing the new card ?>>Driver Sweeper<<

Are there known issues with graphics cards?

I have an Intel Core i7 2.66 GHz with 8GB of RAM and a graphics card with
Intel HD Graphics
Type:    GPU
Bus:    Built-In
VRAM (Total):    288 MB
Vendor:    Intel (0x8086)
Device ID:    0x0046
Revision ID:    0x0018
gMux Version:    1.9.21
My screen occassionaly gets completely scrambled, where I move the trackpad and windows and other things will ghosted items will materialize in the background, though I am unable to click on anything or do anything, so I have to cut the power. This happens when I only have 1 or maybe 2 programs open.
Are there any known issues with the graphics cards on these Macbook Pros? Anyone know what might be causing it?
Thanks.

Saw this on another post.
Applecare Senior Advisor Txx Bxxx (I have his contact info in an email he just sent) just confirmed with me that the problem people are having with the App Store not loading is an apple issue with there servers, ITS NOT YOUR IPAD so don't go restoring it!   It's not happening to everyone however but they are looking into it, its really hit or miss.

Try this first - Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
This works for some users. Not sure why.
Go to Settings>General>Date and Time> Set Automatically>Off. Set the date ahead by about a year.Then see if you can connect to the store.

Issue with Graphics card...suggestions?

So I currently have a 17" iMac 1.83 ghz Intel Core 2 Duo (Late 2006) that we were using as a secondary desktop for our daughter to use. Last summer, after loading Lion onto our current iMac, I tried loading Lion onto older iMac after upgrading the RAM to make it compatible. The RAM install went fine and was tested and all was good. After the Lion install, the screen went squiggly indicating some kind of graphics issue.
I had my friend inspect the issue (who is a Mac Genius) and he confirmed after various tests the graphics card went bad. He further informed me that the card can only be replaced by replacing the motherboard since the graphics card is integrated into the board. Sounds like a costly fix, according to him, for a secondary computer.
My issue is, is it common for graphics cards to go bad like that? Did the Lion install have something to do with graphics failure? It all just seemed weird to me since the machine never gave us any issues in the past? Any thoughts or suggestions would be welcomed!!
Finally, what would be a fair price if I tried selling it for parts on CL or eBay?
Thanks in advance!!

Sure is it is in the upper hundreds of dollars. My friend just had one replace under warranty and it would have cost $800 out of pocket.

No, it is not common, although Apple did have a GPU supplier that provided some faulty ones in a few instances: http://support.apple.com/kb/ts2377
Did the Lion install have something to do with graphics failure?
No. Installing an operating system should not cause a graphics card to fail. Just a coincidence.

Whatever you can get for it really. I'm not sure how one can accurately assess a value correctly on a Mac with such a crucial hardware component gone bad.

Strange issue with graphic memory in Satellite Pro 4600

When I try to open two windows at the same time, the operating system seems to fail. Only option is to restart.
For example: find a page on Google, select the page, and use a link at the current page. Display shows two screens, but no action is possible.
Operating system is Win98SE?
Can anyone help me?

It may not be the graphic memory because when something is wrong with graphic component you will usually see artifacts such as dots and lines.
You may try to remove one of the main memory first, (not graphic memory it's not possible) and if that doesn't fix it then,
try to install the win98 again and if that still doesn not fix the problem
it could be your motherboard or the graphic card as you mentioned, which means, in either case since the graphic card is stuck on the motherboard, you will need to replace the motherboard.

Firefox on hp laptop always open with option of safe mode or reset how can i get it to open without option.desktop doesn't do this. Doug

I set up firefox on laptop first and it always requires that i choose to open in safe mode or reset toolbar, how can i change this without reinstalling firefox. My desktop does not require that i do all that it opens with everything in place. I don't know what i did different when i downloaded it on desktop.
Doug

Make sure that you do not have the Shift key pressed when you click to desktop shortcut to start Firefox.<br />
Also check the Properties via the right-click context menu that the -safe-mode switch isn't appended to the target (command) line.

Can only start Windows 7 (installed with bootcamp) in safe mode

I installed Windows 7 about 3 weeks ago, everything has gone smoothly until a few days ago. I can only start Windows in safe mode, if I try to do it in normal mode, it starts to log in but the screen will just go black and the computer will shut off completely. Then it won't turn back on for like 5 minutes. My mac partition works fine, and I can't find a solution to this Windows problem. When I try to do the "restore' thing where you make it go back to a certain install point, it gives me an error. Please help me, I have a course starting in 3 days and I need Windows OS for it.

Post your question in the BootCamp forum.

Issue with Graphic Adapter on a T400 model 6475-CA6 - BSOD daily few times

From the many T400's we have installed there are a few which cause blue screens while working. To us it seems something to do with the graphic adapter or driver or ?? Anyway, when we disable the power saving features to issue is gone..no matter how hard we stress the laptop..the problem has been gone. When we enable the option the problems start again.

Issues with graphic card on Macbook Pro 2011

I just having problem with starting my Macboook. First, at start screen (gray background with the apple logo) appears pink/red horizontal lines over all the screen. Then, when i'm using my computer, screen goes black for no reason and i need to force restart to turn on the Mac.
I can see that many people is having the same problem. ¿Someone knows what's going on? I can't believe this is happening to a "HIGH QUALITY" expensive computer. This seems happening to 2011 Macbook Pros...
Joaquín.

I had a similar problem on my iMac some years ago, and it was due to a graphic card failure, so I think it is the same problem for you. As it is a hardware problem, the only option is to take it to an Apple Store or reseller to get it fixed: you will get it fixed for free if your Mac is in warranty or if there is a replacement program.

Issues with graphics with W530

Everytime I try to play a videogame or even other media related programs, they will start up no issue. But the visual is all distorted, discolored and pixelated in this flickering madness. Is this a driver issue? I've downloaded the most up to date drive from nvidia but nothing as changed.

Hi again, tabitante12
I did some research and found a similar issue experienced by other users, as seen here and here. These issues were seen on other models with Windows 7, but they may provide some insight to your issue. For users in these links, the issue dealt with the power settings. If their computers were not set to Maximum performance in the power settings, then this issue would occur, so I would check this and see if that is part of the issue. Also, I would recommend downgrading your current driver version to the latest supported by Lenovo, which can be found here, just for security and compatibility. Finally, if you enter the BIOS, what is your Graphics device setting set to? This can be found under Config ► Display.
Best,
Adam

Acrobat 9: Issue with Graphics Looking Distorted

Hi all. I'm sure that the answer to this is very simple and I am doing something ridiculous ...
I use Microsoft Publisher (2007 version) to create documents, and then convert them to PDF using Acrobat 9. Recently, I have noticed that many of the graphics elements that I use are looking distorted when viewed onscreen. They print out looking as smooth as they did in the original Publisher file, but are a lot less so onscreen. Seeing as many people read PDFs onscreen now, this is a bit of a worry.
I have tried saving graphics as JPEGs, GIFs, PNGs and TIFFs (in PhotoShop CS5) and get the same issue each time. Also, the quality between one save and another can be extremely variable. In the example I have attached (the top section is a screen grab from the Publisher file, the bottom when convereted), once or twice when saving the rotated image looked utterly dreadful (as in completely usable). However, when I would save it again a few minutes later, without having adjusted anyting, it looked a lot better.
In the example below, you can see our company logo and also the lines around the photograph don't look great. (The rest is just text, which always looks great.)
Any settings I am missing ... other PDFs I have seen always look great.
I have set the the PDF conversation to High Quality, so am not sure where I am going wrong.

Issue with graphical variable usage

Dear All,
I have a scenario where in based on the availability of 3 different fields(in target) I have to pass a certain values to another target field. I am using graphical variable(LGORT_STATUS, KUNNR_STATUS and LIFNR_STATUS) for each of the field and setting them as 'true' or 'false'. I am trying to use this status to decide on the value to be passed to another field. But unfortunately I am unable to do so. Kindly help me with it.
Please find attached screenshot of the variable values.
Regards,
Vishal

Hi Harish/Osman,
First the actual field(For Ex: LGORT) is mapped based on certain condition and pass the value. Similar condition is used to passed 'true' or 'false' to the variable. Later in the mapping I want to use this status(for LGORT,KUNNR and LIFNR) is used to determine value for SOBKZ.
Regards,
Vishal

Issues with graphics from PowerPoint

So I have a PowerPoint 2010 presentation with lots of graphics that are transparent. When I try to select "save as image" in powerpoint and then insert that image (as either gif or png file) into captivate, I get terrible resolution and weird jagged outlines around the graphics. This only happens with these transparent PNGs. The image renders perfectly in the captivate program window. But when I preview in a browser the images look terrible. I've spent way too much time already on redesigning graphics, playing with various png formats (8, 24, 32). At this point I'm doing screen shots of the slides with transparent graphics, saving the whole slide as an image and pasting it into Captivate.....not a very efficient solution.
Does anyone have any tips or advice for me?
Thanks in advance for any info.
S

Sure do. Change your slide quality to High Quality 24 bit on any slide containing these transparent graphics. Then republish and take a look.
