just exchanged my motherboard. It works.... During the installation I thought at first that the motherboard is again, broken but it appeared that the power supply is the problem (again!). I boot up using another PSU, and changed the settings, and now I got a fully working motherboard and 12GB RAM now. Now I only need to wait for the replacement of the wretched TV Tuner.
Unfortunately though, during the installation, I experienced huge amount of static (I was electrocuted several times - it tickles) even though I am using a wrist strap. I am a bit worried about this might slowly degrades my components inside. Any idea on how to get rid of this static. I will be away for a while. What is the best thing I should do before leaving the PC, considering that there is a lot of static.
EDIT:
I have just received a reply from Gigabyte, advicing me to upgrade my BIOS to FE. As far as I understand, FE version is still in beta. What is your experience for beta BIOS? (Sorry, I am pretty new to Gigabyte products, hence asking lots of questions)
EDIT (again):
apparently FE has been out of beta. disregard my previous question
