windows 7 - Chipset GPU causes a massive slowdown

My AMD Radeon HD 7700 recently broke (fan stopped working and GPU overheated), and now I'm running on internal chipset graphics, and it causes a massive slowdown of the whole PC.

I've changed the graphics memory from 32MB (minimum) to 256MB (highest), and it hasn't made any difference whatsoever. I'm using Windows Aero, and disabling it should have made a small difference, but it didn't; the whole PC is still slow.

I know that it's not the computer build, because I built it myself, and it was a lot faster when it had the AMD Radeon HD 7700 in it, which is the reason why I believe it's the internal chipset graphics that are causing the problem.

Is this behavior normal? I don't have the cash right now to go out and buy a new dedicated GPU.

I'm using an ASRock N68C-GS FX motherboard with an AMD FX 4100 (overclocked to 4.3GHZ), with 4GB RAM. The overclock was an attempt to resolve this issue, and it isn't related to this issue that the integrated graphics is causing a slowdown.

I'm also running on a completely clean install of Windows 7.

Device Manager, as someone requested it:

Have you completely removed the AMD driver and cleaned your registry with CCleaner?

Even if your integrated GPU is AMD, I would uninstall and re-install the drivers for good measure.

It is possible that your integrated graphics are not being utilized at all so having the CPU process your interactions with the GUI would explain this slowdown.

It is also possible that you have not installed all of the chipset drivers so Windows doesn't know how to interact with the integrated graphics.

Check your device manager and make sure it lists your integrated GPU:

I am also assuming that you have removed your dead GPU right?

Update

From your screenshot I see you are using the drivers provided by Microsoft Update. You should try uninstalling the driver by right-clicking on that item in the device manager and choosing Uninstall Driver. When Windows tries to install it again, do not allow it to do so.

Get the latest driver from nVidia and install it. Make sure you are cleaning the registry and rebooting your PC after each install/un-install.

I'm seeing the following frustrating behaviour with my home PC (running Windows XP Home; dual 2GHz CPU, 2 GB RAM, NVIDIA GeForce 8400 GS graphics card). I'll be doing some fullscreen application - usually a game - which has been running at a perfectly respectable frame rate for a while, perhaps 5-10 minutes.

Then, with no visible cause, it'll suddenly slow down massively, displaying only 1-2 frame a second, and holding up processing correspondingly. As you can imagine, this makes most things pretty much unusable or unplayable.

If I do persist with trying to use it, then after 5 or 10 minutes, it'll suddenly recover and return to full speed. But after another 10 minutes or so, it'll do the slowdown again.

This happens with several different games, all fairly recent ones. It doesn't happen when running games in browsers, even if they hit performance issues. Nor does it happen on video playback. Forcing the app or game to change screen resolution does fix the issue, but only temporarily. After another 5-10 minutes the framerate will drop again.

I've tried:
*) Updating the drivers for my monitor and graphics card
*) Running one such game in windowed mode rather than fullscreen - to my surprise, the issue still occurred there
*) Disabling my virus scanner and wireless internet connection
*) Rebooting immediately before starting the app or game
but none of them prevent the issue from happening.

Does anyone have any suggestions for what might be the cause, and/or how I could fix or work around it?

My apologies if this is too "gaming-related". I think it's a graphics or graphics-card issue and not specific to games, but if you want to close the question as too gaming-y I'll understand.
