Hi!

A few months ago my gpu failed. I shelved it in the hopes of buying a new one but cant seem to afford one at the moment.

It boots only in safe mode not in windows with drivers installed (BSOD with "atikmdag.sys" or "atikmpag.sys").

As such I would really like to try my had at fixing it, its out of warranty. On thing I did notice is that the memory chips get quite hot, could it be that they are being delivered excessive power?. If so what components would i need to replace?

Here are a few pictures of the GPU.

Any and all help will be appreciated. Thanks.
 
Solution
That is because it is not using the AMD drivers when in safe mode and without the drivers installed, just basic windows VGA 2d drivers. It is not using but fraction of the memory that way.

how is it that the GPU works fine when in safe mode and when no drivers are installed?

Shouldn't it have not worked at all if the vram had failed...
