DV6-6145dx freezes upon _exiting_ full-screen 3D applications/games.

[q00u]

My DV6 can run 3D games with no problems at all. HOWEVER! The moment I exit the application, the computer completely freezes up with black screens (both main screen and external).

This seems to happen only when exiting full-screen 3D applications.

I have the latest video drivers, and a memory scan turned up no problems. What should I check next?

Update: It freezes up when exiting full-screen mode, not just when exiting the application. As in, if I change the in-game settings to be windows instead of full-screen, everything locks up on black screens.

Double update: It *only* happens when the external VGA monitor is plugged in! Disconnect that, and everything works as it should. But, with the external display connected, changing from full-screen to windowed freezes up everything.

Actually, Fn keys still work. Fn-space toggles the light around the touchpad, Fn-F12 changes the color of the wifi-connection light. Caps-lock doesn't work though.

Also, sound continues to be played briefly after the freeze, but then goes as silent as the rest of the system.

Disconnecting the external monitor _after_ the freeze does not fix it.

Triple update: OK, after further testing, it *doesn't* only happen when the external VGA monitor is plugged in. I just rebooted with the external monitor disconnected, never plugged it in, started full-screen application and changed to windows mode. Crash.

I'm not sure why it worked previously to disconnect the monitor and then change from full-screen. It's difficult to troubleshoot, because it constantly locks up and requires a hard restart.

Any suggestions from anybody? What to try next? Anything else to help isolate the cause of the problem?

Hello,

You've earned this: please right click anywhere on your desktop and then click Graphics. Make sure that you have the graphic settings properly adjusted, leaning towards Performance should do, okay?

Hi SSDdrive,

There is no "Graphics" option when I right-click. What system are you on? This is a DV6-6145dx, running Win7.

I found a Performance - Quality slider in the AMD Vision Control Panel (under Gaming Performance | Standard 3D Settings). It was in the middle (Balanced) and I slid it to Performance.

However, that does not seem to have changed anything. Going from Full-Screen 3D to Windowed locks up the computer.

It runs fine in Full-Screen 3D-Accelerated mode without any problems, it's just that when I try to quit, everything freezes.

Hello,

Apparently you don't know anything about win7, your model laptop or the CCC? "There is no "Graphics" option when I right-click. What system are you on? This is a DV6-6145dx, running Win7." !

Here is a link to your laptop specs:  http://www.notebookcheck.net/HP-Pavilion-dv6-6145dx.64802.0.html

Here is a link to your gpu: http://www.notebookcheck.net/AMD-Radeon-HD-6620G.54675.0.html

Here is a link to your cpu:  http://www.notebookcheck.net/AMD-A-Series-A8-3500M-Notebook-Processor.55755.0.html

 and none are impressive.

I mean, there is no "Graphics" option when I right-click. Look:

Nothing says "Graphics". OK? I'm not trying to insult you.

Does anybody ELSE have any helpful suggestions regarding my initial problem: The laptop freezes when I change out of full-screen mode in any program.

Hello for the last,

 Now you're just being. . . whatever. . . . The graphics is the AMD VISION Engine Control Center,  which is the Catalyst Control Center, which is where all of your laptop's graphics settings abound.... Ende of transmission-
