I haven't done anything yet. My laptop is getting worse and worse. It hangs sometimes, the network connection stalls, CPU gets to 100% for not apparent reason, etc.
I contacted LG Service about the wi-fi problem and they told me to reset the router... can you believe it? I contacted them again and told me to open a proper ticket so they can service my laptop (that I cannot afford as I need for work).
I'm going to try to install XP this weekend to see whether I have the same problems.
BTW Jonas, do you also have problems with CPU at 100%?! I use my laptop for DJing and after 2.00 hours it normally gets completely unstable and I have to reboot

.... I'm really not sure whether this is Vista, LG or both
