helllo...
i formatted my computer. i lost my motherboard CD. so i downloaded all the drivers from asus website i.e the chipset, raid, IDE, audio ect ect
once i finished installing them the last thing i install is the graphics driver which i downloaded from the nvida website. it is a GeForce 7300 GS. now i downloaded it i installed it. all is going well it wants me to restart so i restart but when it gets to the windows loading part it crashes and doesnt load i can tell cos the bar stops moving and nothing happends for couple hours :p.
so now i think maybe theres a problem, so i format again and try again cos got nothing to lose cos i jus formatred before btu the same problem happends again so i dont know what to do :/
can anyone help ??
