First of all hello everyone! I have been lurking on this forum for a while reading GPU repair threads. Now I finally registered to seek some help from you repair gurus.
So my friend asked me to try and diagnose his ASUS R9 290. It is showing static vertical stripes which have different positions at different resolutions.
Also the card will not boot into windows with its' driver installed. The card also had one blown capacitor which I replaced.
We have already tried flashing the stock BIOS but it does not solve the problem.
Checked the voltages and all of them seem to be present. I also measured some of the resistances on the card.
The one thing I don't understand is why there is only 120 ohms between +12V and GND of the 8-Pin PCI connector. The 6-pin connector is showing much bigger resistance.
I suspect that a memory chip might be faulty, replacing it would not be that hard, only problem is how do I find out which one it is.
I would appreciate any kind of help.
