i did but it didnt work...can i reset the bios somehow...or do i need a new mobo???
When he says reset all devices... He means it. Remove and clean the contacts with a small amount of distilled water or alcohol and then reseat.
If that doesn’t work then remove everything that you don’t need to boot, including the HD's and test with that setup. Now reseat your gfx card again. Good. Now do it again, seriously this is normally a graphics issue. Test your ram. More than one stick? Remove one. Test. swap sticks. Test. Try a different gfx card with a buddy if you can. Same for your ram. Eliminate all the easy stuff and rule out everything else till you find the problem.
Also the fact that you are getting an error beep means that the system is able to test itself and TELL you something is wrong. Like the check engine light in your car. When it comes on you know something is wrong, most likely not the ECU but something with the engine.
