Display problems with my newly built computer, where monitor periodically loses signal then gets it back a couple of seconds later.

[kiyip]

I just built a new computer for my aunt and everything is working very well, except for one thing. When I connect the computer to a monitor, the screen will periodically lose signal. I have tried two different monitors and two different cables (both vga). The problem seems to be random and only happens when I am booted in window. There are no problems in the bios screen. I haven't hooked it up to another input yet because my aunt only has a vga monitor and doesn't want to buy a new one. Also the computer remains fully functional when the screen blacks out, I typed about half of this while the screen was off. Anyways has anyone had a problem like this before, or have any solution to offer?

 

TROUBLE SHOOTING ATTEMPTS

I tried two monitors, both of which work with other computers.

I tried two cables, both of which work with other computers.

I reinstalled windows twice.

The bios is up to date.

if you disconnect or connect a display, your display may blink or flicker as your computer detects and configures it, this is normal.

what are your windows power and screensaver settings? 

does the display return if you turn off and on the monitor?
