I purchased components for a custom PC and got some help from a friend to build it. http://speccy.piriform.com/results/nk2atXAZmceeVjOf2Ky6...
With my first graphics card (http://www.asus.com/Graphics_Cards/GT6402GD3/) I got random dots on the screen and blue squares would appear when playing games. I sent it back and got it replaced with the same model. With this graphics card, when I use VGA it is fine but when I use HDMI or DVI the screen cuts out randomly and then starts flickering between displaying and not showing anything in between every few milliseconds and every ten seconds. I tried with a different monitor and it still cut out when not using VGA. I sent it back and they could not find anything wrong with it. I have tried updating BIOS, GPU drivers and formatting Windows. Is there anything I can do that I haven't tried. Thanks

ok, if:1. The card works fine with hdmi in another PC and
2. The same issue happens on another monitor with your PC
This could potentially mean your looking at either a PSU, or mobo issue
Firstly though, try dropping your resolution down from 1080. Does it help?
What model PSU do you have?
Same issue with lower resolution on both monitors. PSU is a Shuttle PC63J, came with the case and motherboard (Shuttle XPC Barebone SZ77R5).

hmmm in that case, seeing as someone else has tried your GPU in their PC
See if they can try their GPU in your PC
If it has the same issue, then looks like you might be a PSU/mobo issue. In that case you would need to speak with the place you bought the shuttle parts from (if it was bought very recently), or with shuttle themselves.
However, if their GPU works fine in your PC, that would unfortunately suggest they've given you another faulty GPU.

Best solution
http://www.lg.com/uk/monitors/lg-IPS234V-led-monitor - 1080p, dvi, vga, hdmi
http://www.aocmonitorap.com/sample_site/lcd_monitor/lm7... - 1024, dvi-d, vga - 8ms
That AOC is crap.
I think you need to have same resolution monitors anyway. But the connectors are there - vga on the aoc and hdmi on the flatron
