Hello guys, Before 2 days i bought a new mother board: Gigabyte G41MT D3V (s775, DDR3, VGA) plus Corsair Value 4GB DDR3-1333 Ram Dimm + one MSI 1GB GDDR5 graphics card.Using those 3 things plus an older proccessor , power supply and hdd i made up a new pc. The problem is that when i'm trying to install windows 7 it normally says windows is loading files but after that, when Starting windows appears it just freezes and the logo doesn't move... so i can't install windows 7. I also tried to install windows xp pro sp3. well this time things are kinda better as xp os normally installs but still when i'm done with the installation progress and my pc restarts i get the logo and.. it freezes again.. the windows logo just won't move. in addition i checked my power supply, ram , graphics card , hdd , cpu using other pcs and all of them worked nicely so i'm pointing at the mobo.. what else could it be? and something more i 've noticed that my mobo supports dual channel memory but the one i bought is single channel.. idk if that has something to do about this.. just mentioning.if you need more info tell me ..
