What is the model number.
Found this on the internet,
The Xperian from Hi-Grade has no good points.
There are plenty.
I have never had so many problems with a PC as I have with this. The Xperian has a known fault with the graphics card and in my experience will last no longer than 3-4 months. The internal fans are not man enough to cope with the heat that this PC produces which causes the graphics card to quit. Try and get something out of Hi-Grade to fix this problem and I hope you have better luck than I did. If the PC goes wrong and it's out of warranty (after you have spent £1400 on it) and it's a day over the 12 months then they want £75 and that's just to collect it.
Whatever you do, DO NOT BUY THIS PC, you will thank me in the long run."
