I just built my first computer and everything seems fine except at random times, my display 1 (i have dual monitors) has a black screen for 3 seconds, then it appears again for 2 seconds, then it's black again for another few seconds. After doing that for like 3 times, it stops and works like nothing was wrong. Then, maybe about 5-15minuetes later the same thing happens.
Here are my specs:
Asrock Extreme3 Gen3
Intel Core i5 2500k
XFX Radeon HD 6870
Kingston HyperX 1600mhz 8GB
OCZ modXstream 600w
Oh, one other thing, my OS is windows 7 64bit except i just used the 3 backup disks from my acer laptop (which runs win7) and surprisingly it read and worked and so now im using acer-windows7 OS. (might be the cause...)
Please help, it's getting REALLY frustrating...(it flashed blackouts twice just while typing this post )
Check the monitor connection to the video card as it might be loose. If that's not the case, try updating your drivers. If neither of these help, check the GPU's temps - you may be overheating or something (above 70C (unsure on this) is cause for concern).
