I've had this issue for a while now that the comp randomly powers off during login attempt when booting into Windows 7, I'd say it's about a 50/50 chance for it to happen. In rare cases it can happen while playing some game too and I'm not sure if it's gamespecific prob of any kind but I saw some other people with this similiar issue and he said it was worse for Steam games and TF2 etc. Anyway that might happen like once a week at tops even if playing for 3-4hrs straight and no notice of errors when booting into Windows after that. It works just fine when I manage to login and LinX runs fine for a while at least and also MemTest.
I don't get any minidumps but event log logs these "critical" issues "Kernel Power" EventID: 41 and sometimes I get the bugcheck code 292 but most often not.
Then in device manager I have this "unknown device" with the exclamation mark and it says the drivers aren't installed. Then when I click on it for details at location it says "Intel(R) P55 Express Chipset LPC Interface Controller - 3B02". Now I've tried lots of times installing the intel inf chipset drivers both the drivers included on the CD and the latest from intel homepage but no matter how many times I do it, the exclamation mark still stays for this device.
The above might very well be related to the problem I'm having but how to fix it is a good question. I'm pretty sure this has to be a driver conflict of some kind. What seems to be a problem is that the chipset drivers are already installed as I install Windows 7 and it seems to think these are the latest ones and installing the latest from intel's homepage won't be applied. Is there anyway to remove the chipset drivers? :p
