I recently set up a box with the following specs: Intel DH55HC i5-650 Processor 4GB Ram, PC Powr & Cooling Silencer 750 After assembling, I could not get the setup to POST or to enter the BIOS. Tried several times. Finally, I tried inserting an older ATI 1950 Pro and everything worked fine. Installed Win 7-64, updated BIOS and everything runs great. I have attempted to remove the vid card a couple times to use the onboard video. I uninstall the vid card driver, reduce the screen resolution to a lower setting, power down, remove the vid card. On restart, I get POST and can enter the BIOS, but when it wants to load the OS, I get a "CANNOT DISPLAY THIS MODE" message, but I can tell from the sound that Win has loaded. Intel has an updated driver for the onboard graphics. When I try to install that, I get an error message that " This computer does not meet the requirements for this software". Is that because I still have the add in vid card still present. What do I need to do? With the 1950 Pro card I see a Win experience rating of 5.9. What would I likely see with the onboard graphics?
