well i own a BIG 6600 agp card 256mb. Now i was experiencing some restart problems while gaming a few mnths ago . i thought it might be my crappy mobo n all coz i had via nd i had heard that there are problems with that chipset . Now i hav a new pc but with a pcie slot only. so i tested out my gc on a friends comp ut had problems there too . so i guess sumthins wrong with da GC . Now since its under warranty , 2yrs+ left , i want it replace. But since i dont hav da box but hav evrythin else retained , plus da bill , nd no physical damage n all, will there be any replacement problems ? If not, how to go about it ? And will BIG replace it for a PCI-e card (since PCI-es r kinda cheaper)?
