Hi, i really have a problem! I have a ctx monitor, wich is very bad, becaude i can´t see nothing(contrast&brightness are to small), so i decided to get new monitor. Then a friend gave to me an old monitor, and i was very happy, hehe. But then, when i tried to plug in a monitor, motherboard started do beep. sound was like piiiiiiiii, pipipi, or something like that. On monitor i see juts some colors, wich are jumping left and right. Please, can someone advice me something, because i am getting

Reseat your video card. It probably came loose.

Either that or the refresh rate is set too high. Boot to Safe Mode.
