hey i been downloading a bunch of betas and what not, more often than i would like, the games randomly blank out and the monitor will display "out of range" or some terminology similar to that (tried 2 different monitors, i have lowered the resolution but i dunno what else to do.

xt1600 graphics card perhaps not able to handle it?

try lowering the refresh rate (hz) and updating your directx/graphic drivers, or patching the game(s), if its betas they could easily just be bugged.
