Ati Tray Tools is no longer facing the issues described in the below article, but it is a great reference for troubleshooting att/driver issues.

As stated earlier, Windows 7 requires digitally signed drivers. This is a bummer if you want to run an awesome application like ATT rather than crappy CCC. The fix, as you may have guessed, relies on DSEO. Download it, run it, agree to prompts, enable TEST MODE, and reboot.
Following the reboot, install ATT but do not launch it. Instead, head over to its installation directory and locate atitray64.sys and atitray.sys – these are the unsigned drivers.
Launch DSEO, select sign a system file, and manually enter atitray.sys and press ok. Do this one more time for atitray64.sys Now you can run ATT without problems.

Whats with the “Test Mode” in my bottom right corner.
That the drivers work in test mode OK, but is it possibleto get that notivication away?
in DSEO select “remove watermarks” and it will remove testmode watermark.
ATI Tray Tools would still change my Refresh Rate back to Default (Disabled) everytime. Does this have anything to do with your article? Your article was the only lead i have to solving this problem. It did not fix my issue, however.
Hey,
do this:
Enable refresh lock in Ati Tray Tools, and in customize click the arrow so it populates your list with max refresh rate. This works like the program Refreshlock and sets the maximum refresh rate your monitor supports for every resolution.
Activate the change by leftclicking on the att icon and selecting a different resolution. There’s also an option to remove the confirmation box.
I am using Win7 home premium. I started DSEO (as Administrator), signed the 2 .sys files (checked the date to make sure they were signed). rebooted, startet ATT – got a Blue Screen and automatic restart. Couldn’t read all the text on the blue screen, but it was complaining about “atitray64.sys” something in a nonpaged area … here is the error report:

Can anybody help, please?
This error can be caused by faulty hardware, anti-virus software, a corrupted NTFS volume or a bad system service.
Disable your AV and try this again. If that does not work run memtest to see if your RAM is faulty. If the RAM is ok then boot to windows, safe-mode or otherwise, and in the run menu type “chkdsk /r /f” , press yes when prompted to run on reboot. If this does not help, defrag your harddrive or something.
PS: I can’t access your C:\
After I follow the instructions. I open ATI tray tools and my screen halts for a second and black and white vertical lines show up on the screen and I have to hard reboot. WTF?!
Ouch! That’s not supposed to happen, likely has something to do with your driver acting improperly. What driver version are you using? What windows version are you using 32/64 7/vista? What is your videocard, agp, pci, onboard?
-Make sure ATT is not overriding the refresh rate of your monitor, or forcing some sort of weird resolution or setting. Try without ATT running on startup, does it boot fine? does launching ATT cause the screen to go crazy?
If those don’t help uninstall your current drivers using the Ati Uninstall Utility from Add/Remove Programs. Then grab the latest from the ati website; if you want to go the extra step then install the driver using add hardware –> “have disk” option to ignore any ccc or ati install utility conflicts, otherwise you can just install normally without CCC.
I just followed your steps and it worked fine in test mode but when I relaunched with no test mode it doesn’t work. SHouldn’t this sign the drivers permanently?
Testmode is to be enabled once prior to reboot, it will remain on. Unofficially signed drivers can only be run in test mode.
So, enable test mode, sign the drivers, reboot and don’t touch DSEO again
my AVIRA found a virus in DSEO… false positive?
and, on the right down corner of desktop appears:
“test mode
windows 7
build 7600″
… why?…
tnks
1: Virus is false positive
2: Launch DSEO and “remove watermark”
alternately you can disable test mode, but that would probably disable the newly signed file
nice post, thank’s I’ll be try, it’s very useful for me
