What causes this issue with the display?

Help me settle a debate I'm having with a friend. What causes this?

Thanks for your time.

Edit: AMD Athlon II X3 450, Biostar A880GZ, 1x4GB Patriot DDR3-1333, WD5000AAKX. Monitor is hooked up to the motherboard's VGA port.

Insufficient data. Does this happen:
- At power on?
- During boot?
- After boot?
- After booting in safe mode?

Does the computer produce sounds indicating that it's booting properly? Do you have a speaker on your mobo to listen for beeps?

The debate we're having is given the information in the post (video and system specs only), how many problems could reasonably be expected to cause the aberrant behavior.

I can think of a few plausible problems The most obvious:

- Onboard Radeon HD 4250 overheating/malfunctioning.
- Driver problems - if it's booting in the first place.

The monitor appears to be a CRT, so I wouldn't expect a monitor malfunction to look like that. The problem is digital, not analog, because those blocks look sharply-defined.

Now, the 4250 does use the system RAM, so that could also be a problem. And it does get its data from the CPU, so I suppose a bent/broken pin might cause garbage like that.

I've seen something similar to this happen twice and both times, buying a new video card fixed it.

I've seen defective 4250 IGPs, in that when hw accell is enable in flash player, then watching online videos look blocky and messed up.

Looks like a digital error of some sort. The IGP is probably accessing a faulty region of system memory. The same physical RAM will be mapped to the IGP every time if the hardware config stays static.
