When i turn on new BUILD it says A7380NMS version 2.0 032408 speed 266x6=15something. Cannot enter bios..hit del and f2 with ps keyboard.nothing.. Also on motherboard bottom RIGHT corner by led connections blue light and red light on... It is a 750i by MSI motherboard. NEW Corsair 4gb memory in dual channel 1 and 3 slots.. new e7400 cpu and heatsink. WD 400 hd sata 3 lightscribe dvd sata 3 in triglon case.
THIS IS A NEW BUILD WITHOUT OS yet. Havent got past that screen... HELP never been stuck like this before. i heard 1 beep. and xfx 9500gt video card. 4 80mm led fans running. 650watt powerkings psu. HELP  i did turn it on and all the fans WORKED too... but still stuck. not getting any further.What does the manual say about those LED's?  Are they meant to convey errors on the board by a combination of colors, etc?When i plug it in the red light comes on... so must be POWER light... when i turn it on a blue light appears right above the red one and still get no further... version 2.0 still.. took cmos battery out for 12 hours.... took memory out and in. unplugged hard drive nothing helps. cleaned artic 5 paste up a little still nothing.Nothing in  this msi manual about that light...BAD MOBO???After further testing nothing... How can i change my bios back to version 1.0 could that be it...You flashed the BIOS ? ?thats the other thing i was studying. i would have to flash by cd/dvd and on msi website they have update 2.1 nothing backwards... It looks pretty complicated with getting dos on cd zipping and archiving... any easy way to do that and were would i find version 1.0 which is on the board...I don't understand...it was either flashed or not.
Where are you getting the BIOS ver. info from ? ?bios version on post stops at dram locks up there doesnt even come up with hit del or f2. frozen not flashed.I had a similar problem a week or two ago. By the sound of it the drive check is not being completed. The second led(BLUE) that stays on is most likely the hard drive "read" LED.
Try disconnecting the hard drive and see if the bios test completes. If you have your Windows boot CD, you can see if you can boot up Windows setup.
I was lucky and the drive that went bad on me was a secondary drive. I didn't have it tested but  expect the drive motor may have died.
