I have LG R405 laptop, the original OS is window vista home basic.
I have ungraded it to windows 7 RC (7100), after that my computer started to shutdown suddenly.
I said, OK, I will install a clean OS.
So, I installed Windows 7 RTM (7600) & the problem persists.
I did not notice any overheating but the fan suddenly goes in high speed & the computer Immediately shutdown. Sometimes when I re-start the computer, it goes off again!!!
So I decided to put the original OS (windows Vista), what happen is, when it was loading from the DVD & started the installation, it went off suddenly. At the end, I was able to re-install windows vista & since then the computer did not do unexpected shutdown. I will keep windows vista until I find an answer!!!!
Is this a problem of windows 7 RC (7100) & RTM (7600) or this is a problem of compatibility???
