processor i5 750 (no video in processor)
Machine worked for 15 months running Linux, using Video Card MSI VN220GT in PCIe slot.
I updated to latest bios using F7 method.
During update video showed progress with expected text until nearly the end and then the screen went black.
I thought the update had failed so I attempted the recover process. No video signal.
Intel Tech said my memory, with 1.6v chips, was out of spec. But there was no beep code with the memory installed and the 3beep code when it was pulled. Wait for 2x4GB sticks to arrive, installed them, didn't work--still no video, no sign of bios, monitor reporting no video signal.
Intel Tech decided that BIOS was corrupted and gave rma instructions. Wait for board to go to Kentucky, warranty board to return. Arrived, but still no video. Tech decided that the original BIOS update had killed a maybe dying video card. Replace video. I took the box to a shop--a test video card showed a bios message complaining that one fan wasn't hooked up. My video card replaced in box showed nothing. So computer working, my video card not working.
Bought new card locally (not easy in small rural town). Didn't work. No sign of video when power turned on. Nothing else hooked up. No drives, no sata cables, no other cards. But also no video. No beep signal indicating lack of video even when card pulled. 3beep code when memory is pulled. Strange. Lotsa lotsa time under the bridge and still no computer.
Read reviews on the new video card which indicated that there were a lot of DOA complaints with it. The interpretation was that certain models of computer just weren't compatible with this design of video card. Took it back for refund.
I think that my video card is probably not broken, just that the newer DH55HC BIOS is now incompatible with a range of video cards. Browsing the suggested links from posting this it is clear that Intel has trouble with these bioses and video cards. Why don't the techs know that?
I've been trying to get this motherboard working for a month now, after having a computer that worked pretty well until I tried to update the BIOs. I have no other machine with PCIe to test my original video card. I'd buy another video card online if I knew of a class of them that works with this board's new bioses. (The only other shop that sells PCIe cards in my small, remote town only carrries only the same model that didn't work when I bought it from the first store.)
If you have a way to fix this, please let me know. Downgrading the BIOS isn't recommended. Might it work for this board and get me back the function I used to have or is it too risky? I've never seen such an implausible set of circumstances before. Again, any help would be appreciated. I'd give up and get a Sandy Bridge i5 and Sandy Bridge motherboard, but my faith in Intel boards is sinking fast. Anyone have experience with Sandy Bridge and Linux?
