GPU problems

i get this monitor flash with Blender only so far. When I move/ drag blender across monitors.When I have a lot of geometry in 3d view it gets really bad there is no geometry here in image / Blender is empty. When rotating my 3d view it is just fine and smooth.




With this card/ my new card. My old card worked fine. I read some one had a problem with the video card chip and Hd combo http://www.newegg.com/Product/Product.aspx?Item=N82E16814127745

I put in the old hardware ( Old video card and hard drive)I had before the trouble and still have the problem. So it is not the new video card and or the video card SSD combo. I tried old video card drivers and sill have the trouble. I removed the ram all but one and tried different sticks and have the same trouble. I have 2 monitors with the same trouble so it is not the monitor. I do not think it is the power supply. I use 6 and 8 pins now and the old card uses only 6 pin. I have more display problems then the 2 images.
So what is left? The mother board and the CPU. How do I test further? I have no back up CPU to exchange.

Are you reinstalling the OS between these changes or is this the same Windows install? What brand/model was your old card?

I got a new card and SSD so I installed a new OS ( win 7). My old card is gts 250 Why? I do not remember the brand xfx??
I put in a new card and SSD and found display problems . So i put in the old card and old HD but the trouble was still there telling me the problem was coincidental with the new hardware. That the trouble was not the new card or HD.

I ran prime 95 30 minutes with no errors.
What makes a screen do this?
Everything is working. Butt something is not.

The only thing I can think at this point is a bad monitor or a bad cable. If possible try a different monitor and cable. It’s possible it is something with the motherboard but I kind of doubt it.
