Memory Dump problem ! Blue screen of death !! HELP

Hey guys,

I have an iMac 27 inch late 2009 running Windows 7 home premium 64bit using bootcamp. My computer specs are

CPU - Intel i7 2.8ghz quad core
RAM - (8gb standard with the imac)
VIDEO - ATI Radeon HD 4850

I installed windows 7 on my imac using bootcamp today. It was working fine until i started installing things and i ran into the blue screen of death saying Memory dump. This message only shows for about 2 seconds and then restarts my computer. It randomly happens, such as internet explorer or just on my homescreen.

Thanks in advance for you help. I am not that computer savvy when it comes to driver issues and BIOS. I will understand some computer "talk" but not all so please explain in simple terms.

Thank you

Please read this thread and attach the dmp files to your next post.

Thanks, Max. I am looking at them and it will take a little while to go through all of them.

consistently over all the .dmps you are showing a problem with atikmdag.sys ?

your driver version is

atikmdag.sys atikmdag.sys+126a0 fffff880`048d8000 fffff880`04f13000 0x0063b000 0x4abaa755 23/09/2009 23:55:17

I suggest find the latest driver for your ATI card and update :)

All 16 of your mini dumps point to the same thing, an ATI video card/driver problem.

STOP 0x00000116: VIDEO_TDR_ERROR

Usual causes: Video driver, overheating, bad video card, ?BIOS, ?Power to card

"It's not a true crash, in the sense that the bluescreen was initiated only because the combination of video driver and video hardware was being unresponsive, and not because of any synchronous processing exception.

Since Vista, the "Timeout Detection and Recovery" (TDR) components of the OS video subsystem have been capable of doing some truly impressive things to try to recover from issues which would have caused earlier OSs like XP to crash. As a last resort, the TDR subsystem sends the video driver a "please restart yourself now!" command and waits a few seconds. If there's no response, the OS concludes that the video driver/hardware combo has truly collapsed in a heap, and it fires off that stop 0x116 BSOD.

If playing with video driver versions hasn't helped, make sure the box is not overheating. Try removing a side panel and aiming a big mains fan straight at the motherboard and GPU. Run it like that for a few hours or days - long enough to ascertain whether cooler temperatures make a difference. If so, it might be as simple as dust buildup and subsequently inadequate cooling." - H2SO4

CURRENT_IRQL:  0

Suggestions:

1. If you have done any overclocking of the CPU of the graphics card, revert to stock.

2. Make sure your video card is not overheating. Check the fan(s) to make sure they are working.

3. Go to the ATI site and try different drivers. Sometimes the latest is not the best. Do not use Windows update nor update through device manager. Download the drivers to your desktop. Uninstall the current driver through Device Manager and install the new driver.

Please post back and let us know the outcome. If any of the other BSOD guys have other ideas or suggestions, they will post them.

Yes, it does feel good. And I do not mind anyone jumping in on a thread where where I am working. We are trying to help the OP solve a problem. To me, it doesn't matter who helps as long as we can help him/her.
