Hi Niki,
As you have updated BIOS to F9 and are still having problems, in my opinion going to F10A beta would not be a good idea. What we need to do is find out what is causing you problems. Could you please post a few more details such as........
Is this a new build or upgrade?
What beeps, if any, are you getting from your mobo when you first power up?
What memory are you using and how much?
What other components have you installed? (Add-on cards, HDD's Etc.)
What is your PSU?
Cheers
