I bought a graphics card (XFX Geforce 7800 Overclocked) way back around mid March.
It had an intermittent fault where I would loose video signal completely, the only way I could get a picture back again was to restart the computer.
This happened regulary during gaming, and video playback, but sometimes it could go for a week or more without playing up, other times it would play up all day and I might be lucky and the problem would disapear the next.
I sent the card back Overclockers.Uk (where I purchased the product) as faulty, explaining the fault and what I had tried etc etc, it was returned and I found out it was the original card, put it into my computer and the problem occured after playing a video for around 10 minutes. I called them up and they said the card passed there benchmark tests (6 hours) and that no fault was found.
I sent the card back again and underlined the fact that this was intermittent and asked them to test it as long as possible, they said they spent the whole day this time running the card and still no fault was found. At this point I gave up as there was no help on the internet and Overclockers were simply charging me around £25 each time I sent it in for testing. I spent hundred's on other computer parts to make sure it was the graphics card and still the fault was there.
It wasn't until about a month later I read a forum where this problem occurs in every overclocked version of this card, and a small team had created a driver to correct the problem until nVidia released a driver to resolve the issue.
This worked and I sent all the documentation to Overclockers along with the card, a 4 page!! word document of everything I have done, other people having the same problem etc
It took a week for them to get round to even testing it this time (Was tested/dispatched same day last 2 times) I was never contacted by them as to what was happening, I had to chase them up and spent 20 minutes in queue on the support line to be told it was faulty and they sent it for replacement.
A whole month passed and I asked for a status report on how long this was going to take, and if they were unable to replace it could they please just refund me the money, along with test fees they charged. Until this day I have yet to recieve a reply from them, as they chose to ignore the problem and hope it goes away.
Now that so much time has passed do I have a leg to stand on when it comes to a full refund? Surely their are laws to prevent them taking the card away for months and not supplying a replacement?
Any help will be much apreciated, I am going to rung them tonight and would like to be armed with the legal mumbo jumbo :)
