I have a ThinkCentre M91P running Win 7 Pro, 64bit.
It is currently working with the default windows 7 vga driver only.
If I try loading the Intel graphic drivers then:
1. The drivers install successfully.
2. When I restart the machine to complete installation, this happens:
- The windows logo appears for a while...
- The pc then automatically reboots.
3. I cannot boot the pc unless I run win 7 repair, which restores the pc to before the driver update.
I have tried (and failed):
1. using MS update driver
2. using Lenovo System Update
3. using drivers from Intel website
I have updated the bios, but it has not helped.
Any clues how to solve this issue?
Thanks in advance

Could be bad hardware, when the graphics shaders are enabled by the proper driver it reboots.
I'm using the current Intel driver 220.127.116.1196 on my M91p with Win7 64.
