Hi there
First time I've seen this thread and am rather shocked at how things seem to have gone wrong at both ends which is very rare. Both OcUK and Gigabyte UK pride themselves on service as can be seen throughout these forums. Just unfortunately on the rare occasion it can go wrong.
Just some comments I will make though on gaming laptops in general:
1. None of them are silent, when under gaming they all get noisy, some more so than others. This is because its the design but some are sometimes louder than they should be due to poor thermal interface materials or lack off or too much.
2. NVIDIA drivers are disclaimer under mobile saying its not always advisable to run an update from what the manufacturer supplies and the supplied driver should always be backed up.
So if your expecting a silent gaming laptop it will never happen, I have still not found one, but in fairness they should not be hoover/hair dryer noise levels.
Now that is cleared up, keep me informed via the forum here as to how the laptop is when repaired and if you do have any more troubles you are well within your right to return the laptop to us and we shall offer a refund, as I make it clear to our staff we want happy customers, not upset ones.
Let us know how the unit is when you get it back and if there is any more issues, post here and I will get our returns manager to resolve the situation to your satisfaction, just sorry I had not seen this sooner. The end result is both OcUK and Gigabyte want you happy!
Lastly once you are happy let me know and I shall get you a load of free games and goodies sent your way.
Though I do want to say Gigabyte service levels have always being fantastic for our customers in general and I have worked in this industry now for nearly 20 years and it is extremely rare for a manufacturer to be trying to call the customer or add them on Skype and be so active in the community and I think a lot of other brands could look at this and learn from it.
Keep us updated!
