Windows 7: Visual problem with ATI Radeon graphics card

I just installed a new ATI Radeon HD graphics card, and for some reason these lines and squares keep showing up on the screen.

Using

intel i7 processor, with Windows 7 32x
4 GB RAM DDR3
ATI Radeon HD 3640 graphics card

I tried playing both Amensia and Hitman, and I think all my other games will have the same problem when I play 'em:








My desktop was having the same issue, but I fixed it by turning off aero and putting the basic desktop on.
But now it's happening with my games.

Help me, Windows7Forum.
You're my only hope.

Let's start with doing this first,



If you're unsure of what anything is this should show you,

Speccy - System Information - Free Download

Also help to know the make and model of power supply you have. For this you're going to have to actually look at it as ther is no way to find out with software.

Once you have done that then it will be far easier to help you.

Thanks. So here's what came up.

DualLife
Model DA - PS 500

OPP: 500 W

It looks like it could be a bad card, which is not unheard of even from new out of the box. If you can test it in another compuer, or failing that take it back and get them to test it.

What you listed for a power supply leads me to believe that it is some no name thing, that in all likelihood shouldn't be trusted to power a light bulb, never mind a computer.

P.S. based on the rest of your specs, unless budget is a concern you might want to look a lot further up the video card food chain as that HD 3640 is several generations old and was low end even when it was new 4 or 5 years ago. It definitely doesn't do just to the i7 2600 CPU you have.

Thanks, Stormy. ^_^

'Cause honestly, it was a video card my Dad got from his office.
It's not brand new, and I sensed that it would not have worked in the first place.

In any case, my neighbor gave me a Radeon HD 5770. Would that be compatible, by any chance?

Coming from an office? It is liable not only being old and tired, but is also likely suffering from possible heat damage as it likely was never cleaned out and dust is a great insulator of heat on electronics.
