Hi guys,

Well, since I recieved my ne Dell Laptop ive had 2 main problems.
1st, From initial startup about 5-10 minutes after bootup regardless of what i am doing, even if i leave the system alone I get a ATI graphics card has failed and recovered successfully message. Prior to this message the screen will freeze, go blank then restart and the message appears.
2nd, If i use the switchable graphics option to make anything start in high performance mode, from Dell support centre to games such as World of Warcraft/ world of tanks, eve online, Steam games etc. The computer Blue screens and give the following info on reboot.

Now I'm not completely clueless with computers but neither am i an expert, so I have tried various methods, from updated drivers, older drivers, updating BIOS(recommend by those ever helpful guys at DELL) please feel free to detect the sarcasm... Ive restored to factory setting a few times, restarted the whole process etc and got nowhere. All the games, programs work perfectly fine on the basic standard Intel HD 4000 card that is on the motherboard but as soon as I choose the 2Gb ATI card the dramas begin.

Ive tried Leshcat drivers, and other fixes. AMD drivers just dont support my card and im currently attempting to get Dell to pick it up and take it away which isnt as easy as it sounds.

But I cant leave it alone... I want to know what the problem is and what is at fault.. all aims at ATI card at the moment but I have no clue.

I have uploaded the ZIP with all system info in it and look forward to your response.

Thanks, tried things like that before, but the card is supposedly discrete and wont activate unless the program requiring it to do so is put into high performance on the switchable graphics settings. As soon as this is done and I attempt to use it i get the BSOD. Ive ran memory tests, and video tests but they only ID the Intel Card. The ATI card is visible in device manager but say if i disable the intel card, the ATI card doesn't function and I lose all Catalyst functionality too.
