Hello, I recently put together a new computer and it is not working . I used my old hard drive cd/dvd drive and sound card from my previous computer. I got an amd phenom II x4 970, gskill sniper 2x4gb ddr3 1333 mhz, zotac gta 450 amp edition, asus M4A88T-M motherboard, diablotek phd 450 psu. When I try to start up the computer it goes through the motherboards screen where it shows to go to the bios and stuff for a few seconds and then it says windows error recovery. Windows failed to start. A recent hardware or software change might be the cause blah blah blah then it let's me choose between launch startup repair and start windows normally. If I start windows then it says starting windows then shows a blue screen for half a second then restarts. If I do the repair then it just asks me to do a system restore but it just says attempting repairs and doesn't do anything else. I then booted the dvd that came with the motherboard and it says loading data then a bunch of dots comes across the screen then it shows me a "welcome to asus motherboard make disk for dos menu rev.1.0" then I have option a) make and xp/xp64bit Ancient/raid driver disk and b) creeks command prompt when I choose a it asks me for a floppy which I don't have and am not capable of using. I have windows 7 home 64 bit. Thank you for reading this and helping me!
