I just got a new computer built and got a new monitor along with it but a problem has arose. I can use the computer but when something that required a lot of RAM or just a lot of priority to open for example "Steam" the software in which you can download games and such (Basically XBOX or Play Station but for computer), It just lags a little bit and goes to no signal. I know the problem isn't with the monitor because I've tested other monitors and I have done the same with the cable. I'm using a DVI cable not a VGA. I have updated my drivers for my graphics card several times and on the GeForce Experience application it says my drivers are up to date. HELP!
