AMD Radeon HD 7600M Series 2.7 GB Suddenly stopped responding problem

Zenakuism · 05 Oct 2013

Hi, I've suddenly encountered a very uncomfortable problem yesterday about my Video Card and I absolutely have no idea where to go on from here.

>Was playing a new game, Unholy Heights. Had to install Microsoft XNA Framework Redistributable 4.0 to get it working.
>Playing on bed, used a pillow to soften laptop on lap.
>Spent Maybe 2-3 hours. Noticed the laptop is really hot. Removed the pillow and let it breathe.
>A few hours later (1-2h) Sudden green pixels appear. Then something like this happened, but was pink

>Restarted the laptop. This happened.

Then notification pops up saying AMD Driver managed to recover. Then Pic #1 after a couple of seconds then I had to manually shut it down.
>Was slightly ok. Although if I watch a video, green pixels show up. If I play a game for more than 5 minutes, Pic #1 happens.
>Annoyed. Went to Safe Mode. Rollback AMD Display Driver. Restart.
>Actually got worse. Can't boot normally now. Went back to Safe mode and uninstalled AMD Driver.
>Now on normal mode, using standard VGA.

Everytime I'm using the AMD Driver. That happens. Not sure why. Maybe a loose connection? Appreciate all help.

Hello and welcome Zena now for starters as you know resting the laptop on a pillow was about daftest thing you could have done as you blocked any air entry into the machine. Now it could be that you have cooked the motherboard as the GPU is served by the same heatpipes that run from the CPU too.

Now worst case scenario is the GPU chip is fried and the CPU too. What model Toshiba have you got??
Just to give you a rough idea of what is inside I have snipped a couple of pics from site I use. What you can do about well I suppose let the thing cool completely first the try again but I wouldn't be holding my breath

Damn. That sounds bad. I have the Toshiba Satellite L850-B211

New problem. Left it with my cousin with the hope of him fixing it. Just came back and it's actually worse now. It doesn't even work now! >.< ahhhh I'm so pissed. Anyways, everytime I turn it on now. Just nothing. Black screen. The numlock and capslock light up sometimes, sometimes it doesn't. I asked him what he did and he said he opened it up to see the status of the graphics card. I think he may have disconnected some wires? Hopefully it's just disconnected wires.

Current Status:

It boots up normally, sometimes it doesn't boot up at all. But the lines come later after 5-10 seconds have passed.

Well Zena the GPU that is fried (in my opinion) is actually fixed to the board unlike the CPU which you can take out and replace. So I am sorry but it looks like new motheboard or a new macine

Hi ICit, well that's a bummer. Lesson learned then >.> oh and by the way, I just recently came from a Toshiba service store here and they told me that it's the LCD that's busted? HOPEFULLY it's the LCD but I don't know man, I think this guy is just trying to squeeze some cash from me because he's referring me to a buddy of his who has a business of laptop replacement thingy, I'm not really sure. I'm not that really familiar with it so yeah, his buddy told me that the LCD costs like P15,000, $347.95 in American Dollars, but he was willing to give it to me for P6,000, $139.18. Find it sketchy though, I'ma try it with an LCD monitor.

Good thinking Zena it should show you if the GPU is fried. The CPU's usually have a fail safe system where they will auto shut down when they get nearer the max operating temp but GPU's I am not sure. Just make sure you keep the receipts for that other screen for a return as I still not convinced it is the screen as it does not go bad as a general rule.
There are some pixel testing software around but see how that plug in works first if it is the sane then it is pretty certain the laptop one has gone south.

Well, looks like it's not the LCD. I tried it with a friend's monitor and it's the same with mine. Completely blank. Oh, sometimes I turn on my laptop when it's been off for quite a long time, and it actually turns on! But then this happens

By the way, just an idea. What if I took out my GPU, could my laptop run on standard VGA? Just a wild idea. All of this started when I re-installed the display drivers.

Sorry Zena as I think I mentioned earlier the GPU is fixed into the motherboard the CPU you can swap out as it is retained only by that plate in the pic I sent but here it is again only maybe a bit clearer.
