I am trying to install Win7 on a pc that says it is vista capable. I dont know how to describe how the display screws up, if you look at the attachment, you'll see what i mean. The pc was doing that on winxp when i got it, i tried to install win7 on it, and when it gets to the completing installation part of setup and loads the display drivers it happens. I've tried disabling all unnecessary hardware in bios inc sound, network, usb, and ive tried increasing the memory available for the onboard graphics.
I've just reinstalled xp for now and so far no video problems.
As i dont know how to describe whats happening, i cant do any research on google.
If anyone knows how to describe it so i can research it, or has had the same problem before, your help would be appreciated.
Thanks in advance,

frankly that looks like the wrong display driver loaded. The slanted lines are almost always caused by that because the system is trying to run a monitor resolution different that what the monitor wants to show.
just for extra testing though, do you have a different 4x3 monitor you can try on it?
I think Lord Orwell is spot on here. Usually something like this is caused because of the wrong driver, bad resolution settings or bad hertz settings.
Have you tried to boot to safe mode or VGA enabled? Both of those modes run at 800x600 which is fairly common and any 16:9 should be able to handle it. Granted it will look ugly, but then you could at least look at the drivers and resolution settings.
I've installed xp on it, it boots fine and works, it just does this instead of a bsod when the pc's under heavy load. Also i've tried it with 2 monitors of different sizes, same happens. I've downloaded the latest drivers and all updates.
I think my onboard graphics have gone, what do you think?

you made it sound like this was a problem at boot. The most likely scenario based on the new info is overheating. Open your case, make sure all fans are functioning and clean the dust out of everything.
Another thought I will offer is: the power supply. You did not mention if any parts of the computer were upgraded. One thing that cannot be checked is the competence of the PSU.
You will boot but the lack of available current to the graphics(5V rail) can lead to similar symptoms that you have described and shown.
It looks like the GPU overheats. This problem, believe it or not, is fairly common. You could try open up the lappie's bottom cover and locate where the GPU is. It normally shares the heatsink/fan cooler with the CPU. There are a few crews holding it the HSF down. Just remove those screw, take the HSF out, clean all surfaces on the CPU, GPU and the HSF and apply some good thermal grease such as AS5 and put everything back. That should take care of the problem. Note that if you see a piece of thermal tape between the cooler and the GPU, remove it and replace with some copper piece of the same thickness (a penny coin with both faces sanded/polished off will be fine)

it's not a laptop.
Other than that, i wouldn't recommend what you said anyway due to the voltage conductivity of a penny. Thermal tape is used because it doesn't pose a risk of shorting out the system.
Onboard graphics probably don't have their own fan but could have a heatsink receiving blow-by from another fan such as the processor fan. If that fan is getting clogged or the heatsink is, then it can cause overheating.

1. All heatsinks are made from metal (aluminum, copper...), so using a copper penny doesn't introduce any new risk of electrical shortage.
2. Thermal tape are being used NOT because it is non-conductive. The real reasons for manufacturers to use thermal tape are (in comparision with thermal paste):
- It's cheaper
- Much easier to apply in an assembly line
- It's sticky so that they can reduce the number of parts used (such as screws to hold the heatsink down) => reduce cost.
However, thermal tape isn't as effective in conducting heat as thermal paste and thus you will not see it being used on critical components such as the CPU.

the heat sinks are metal but separated by non-conductive tape! Your solution removes this. Not only will this pose a risk of shorting across exposed jumpers some chips have (such as the pictured one) but chips like those can't even have arctic silver or copper used. In addition, it's quite easy to break the chip if your heatsink isn't perfectly smooth, as it comes in direct contact with the die. Slapping a penny in there will most likely cause a fire similar to the one i had when i put arctic silver on an athalon xp chip. I didn't know any better and i had people telling me to use it. Yes, the chip caught on fire.
