"Display Driver stopped responding and has recovered" T400 Switchable Graphics Problem

I posted a couple days ago that my computer has been freezing for a couple seconds here and there. I've done some research and have installed some new drivers. However my computer will not let me install any ATI Radeon drivers because it says my computer has incompatible software/hardware... Wrong, I have an ATI Mobility Radeon HD 34xx series.

These are event logs that I have that a couple people in another thread asked for. I did alittle research on them and found that one of the errors looked to be a bad sound driver. I updated my sound driver and I thought it was better but it keeps freezing. But it has not frozen while playing music.

So my question is, How can I install the ATI Mobility Radeon 34xx driver and/or ATI Catalyst Controller when it is telling me my computer is not compatible?

 

You can't just install the official ATI drivers from the AMD website, these don't work for our switchable graphics. You need to install the Lenovo drivers. For mine, I find these here. Make sure you competely uninstall all previous instances of both ATI and Intel graphics drivers and software.

 

i had this exact same problem about 10 months ago.

i contacted some consumer rights rep at lenovo about this and sent my computer to them. its been fine ever since, but i'm unsure what their fix was. it was a fix and not a replacement, but perhaps the mobo or gpu were replaced without my knowledge.

i tried countless solutions and nothing worked so i complained to lenovo. reformatting, various drivers, both integrated and discrete, nothing worked.

i think there is a huge thread over at the lenovo forums about this so i suggest checking that out.

 

I think I have fixed it but it was quite a bit of work.

I booted into safe mode and uninstalled both ATI graphics drivers and the intel graphics driver. I had already downloaded the Lenovo driver for the switchable graphics. I rebooted into safemode again and tried to install it.

It gave me an error. I rebooted normally and tried to install the lenovo driver and everything seems to be working great so far. It has only been an hour or two but I have been doing everything I can to make it happen but I cannot make it freeze again.

 

i'd wait a bit to be sure. and by a bit i mean a few weeks.

i thought i had it fixed many times but it would always come back. five days, two weeks, etc. it would come back randomly.

if it comes back again i'd suggest contacting lenovo.

 

i have had this problem before in my switchable graphics T400, it turned out it was a hardware problem with the ATI.

 

I am starting to believe this may be the case. I thought I had it fixed and it came back today. What did the two of you end up doing in your situations? This is my school computer and I would hate to have to ship it out...

These are pictures from my event log if they help the situation.

 

I've had this problem two or three times with my W500 but that's over the course of 3 years, guess I'm one of the lucky ones.

 

I've had this problem on my T500 for a little while, but it was purely a driver issue. I'd say that's most likely the issue here, and not hardware. Make sure you have the latest BIOS revision, the latest power management driver, and that you install Lenovo's latest switchable video driver package (not AMD's, which does technically work and supports switching, but has a few issues).
