my first PC came from some useless tosspots at a shop called "special reserve". it was an ASUS K8v with 1GB ram, an AMD athlon 64 3400+ and a 6800LE. it spent more time with them than it did with me. firstly, it kept blanking and had to be forced off at the wall socket. their solution was a reinstall of XP. naturally, since they didnt even try, it was still malfunctioning. 2 weeks later it turns out it was the graphics card. when they got a replacement, they had ordered a 6600GT. 2 weeks later it was back again for another issue, and i see the suspect 6800LE for sale in a suspect plastic package for £200! after 3 months, i already felt i knew more than them.7 months from new, the motherboard crapped out and was sent off to their head office. better treatment from there, but the delivery company (DHhelL) smashed the case. a week after they replaced the case after "testing". 9 months in, the dvd drive crapped out. 2 weeks later, i call to fin d out what was taking them so long. it turns out that the useless ass hadent even ordered a replacement.
2 weeks later it was fixed also, a woman had called about the case of her new computer being bent and broken. then, 1 month later, they were in receivership (bankrupt). probably linked with their disgraceful treatment of the customers, being completely full of themselves, and recycling broken parts.
in short, 6 months of a store bought warranty, and i already knew better than them and could have done a better job myself, and would have if it werent for the warranty. i now fix it myself, and will never trust a store again.
just the other day my mate was looking for a laptop (cursed propietary tech, why arent there parts lol) and the guy said that a 9600m GT could run crysis warhead at full spec, immediately showing his ineptitude and complete lack of any knowledge. my mate said his budget was about £900, but the incompetent salesman took him to a £1800 macbook pro.
my advice: never trust anyone other than yourself.
