Well finally I have been able to “solve” the problem of my recent computer crashes!
Bluetooth
Ever since I have my new phone I once every now and then like to synchronize the phone with the compu and I do that with bluetooth. The synchronizing all goes allright, but right after that my computer shuts down. It shows a blue screen with loads of error messages to make sure that you realize that something serious is wrong!
After restarting the thing, it can hold for about 3 mins, even in safe mode, before it collapses again, so that is not good at all!
Solution: go into the BIOS and shut down Bluetooth alltogether. Basically you have to ask yourself how often you use it. And since my answer only is when I want to synchronize my phone, I have decided that it works a lot better to get a USB cable at the Nokia shop and get rid of the mafan once and for all!
