Hi
Sorry for my poor english as first. There is my problem.
yesterday i build new system with
-Intel Dekstop Board DZ77SL-50K
-Intel Core i7 3770k
I installed Windows 7 Home premium 64 bit. and everything works fine until today. I parchused one Radeon HD5450 video card. I installed the latest drivers for her , and everything was fine. Then i tryed to install the Virtu software , because i want to run both graphics adapter. When i click on the setup , it says "No sandy bridge , or Ivy bridge video adapters found , please.. et.c." As usual i think , the system cannot find my integrated HD 4k Graphics. I shutted down the system and move the HDMI cabble from HD5450 into the motherboard . Power up , and no screen . Then i moved cabble back to HD 5450 and screen is shown up. I shuted down the system and go into BIOS. (The BIOS is worked on default , and i am not overclocking the machine yet!) I went to Video configuration settings in BIOS , and i saw that the Primary video Adapter is set to "Auto" , I suggest that System runs on Discrette video first if settings are set to Auto. I change it to Internal Graphics , or i cant remember , i chouce the Second Options i think. Then i click F10 to save and restart. After restart no screen shown up on Integrated Video adapter , also on Discrette. I removed the New video card and i tryed only with Integrated , but no succes. As standart procedurre , i changed the Jumper on the motherboard on "Config" and same problem , no screen . I tryed everything to resset this BIOS Settings back to Auto , but fail. I remove the CMOS Battery for 1 Hour , then i tryed again , fail. I tryed every suggest from Intel Step for Resseting the BIOS , but no succes. Pls can you tell me what to do , to resset this BIOS , i am not tryed to recovery him yet, because i dont want to do that. The machine using the latest bios , i updated him yesterday.
Best regards and thx for anyone who helped here.
