I've just built my first PC from scratch and it went smoothly and everything seems to be running fine. I installed Windows 7 64bit Home Premium and have played HL2 and other source games as well as Unreal tournament 3 with no issues.
On boot however, the BIOS screen is scrambled and just shows blue and white horizontal lines. I read that it is most commonly the psu or bad ram timings. I don't believe it is my psu as it is brand new and there were no issues during the install. Here is my setup, and any suggestions would be greatly appreciated.
ECS Black A790GXM-AD3
AMD Phenom II X4 965 Black Ed. 3.4GHz
G.SKILL 4GB -- 2x2GB - F3-10666CL8D-4GBHK
SAPPHIRE 100283-2L Radeon HD 5770 1GB
Sunbeam PSU-COM780-BK-US 780W
Also, I just updated my BIOS to the most recent version, and the RAMs timing is 8-8-8-21, but it is set on auto to 9-9-9-24. Any attempt I've made to change it to the lower setting has stopped any video from displaying on boot until the RAM is removed. Since its current latency is higher, that shouldn't matter though, or so I thought.
