guys i love this site the threads and replies are extremely helpful, i am stuck here though. i am using a gateway desktop i think its a gx something, i've basically built a new rig, though.. got a 9400 gt video card it came with an acer g43t-am mobo which since acer doesnt make mobos, i suspect is an 'ecs g43t-m' something... i bought a gigabyte g41m lga-775 combo mobo and installed it, failing to realize my psu was a measly 300 watt fsp... got a new psu now, 600 watt, my question is this, with my new mobo installed everything powered up and worked properly, (it was failing to power up at all, fans spun inside case but power light/ video feed were no goes..) but after windows began to load, i got the blue screen.. So.... first of all is my old mobo better than my new one? and second, should i reinstall my first one and just use it now? i am going to try that seeing as how i have all night to make this work, but without a windows 7 disc (my comp came with it installed) i cannot start it up like that, my mobo came with a driver/bootup start disc to recover things but it still leads to a reboot option, everything else leads to blue screen.. so i have no option i think without a full windows 7 disc but to go with the old mobo... will be the 5th mobo swap, i'm getting pissed, you guys are my only hope, i dont know if the gigabyte chipset was compatable with my old one, the guy that sold me it said it was, i cant find out how to check this info he gave me... let me know what you can guys i appreciate all your knowledge and efforts.
