Hi there ... i have an issue with a AMD system that is crashin/freezin all the time... I have changed my old gpu(gts 450) to a fairly new one ( hd 7770 , 20$ on ebay) . I thought that my old gpu is dying , but it seems to be another problem, the pc freezes as it froze with the old gpu... I checked the rams too, i have put in some new ram sticks , it froze up... The psu is fine , i just bought it ... I dont know what can be the problem , so i need your help! SPecs:
