Okay so, im pretty noob about upgrading computer and so on, but about a week ago my Amd Radeon HD 7570 broke down
after 3 years of use... Now i want to get a new graphic card and i bought GTX 750 TI yesterday. Everything went well until i
tried to boot my computer, it started up but froze on the ''Press ESC for startup menu''- screen and about every 40 seconds the computer made a beep sound. The sound happened like 3 times and after that i heard 2-3 fast beeps and the screen went on like sleep mode, or atleast black. I tried updating bios and deleted all my amd drivers but still this happens. I have tried to search for an answer for this problem but i just cant solve it. I read about disabling security boot and legacy modes in bios but i have Win7 and isnt those things for win8? But yeah any help would be good!
