Hello, i have problems with my graphics card ever since i bought it: screen flickr, pc freezes and even vpu recover errors. In my first spec i only had VPU recover error and the PC needed to be restarted after VPU error. Microsoft Windows XP Professional SP3 - 32 bit Processor: Intel Core i7 920 @ 2.67GHz Motherboard: Intel X58 Platinum RAM: 3 GB Graphic Card: ATI Radeon HD 4870X2 with the latest update PSU: EPSILON 80PLUS 700 - Total power 700W I tried to add some speed to my graphics card fan, from 50% to 100% but nothing changed, even got worse, i've received a green vertically stripped screen resulting screen freeze. Finally i decided to install W7 Ultimate SP1 - 32 bit hoping that something will change, updated all drivers and now i just get a PC freeze. After i restart my PC i receive a "Windows recovery error" that lets me choose between safe mode or normal mode. I am confronting with this problem while entering a Dota 2 match. Any help will be appreciated. P.S.: Will it change something if i install a 64bit version of Windows... ?
