Solved Bad bios, how to replace or flash without POST Tags: Chipsets BIOS Flash Motherboards Last response: June 28, 2011 12:41 AM in Motherboards Share Karch_32 June 17, 2011 7:26:17 PM I am trying to build this rig for a friend, and the Mobo and CPU are supposed to be good. It's an ASUS P5W DH Deluxe, and an Intel 641 (775 socket). I have tried two video cards, and those are known to be working. My Antec Earthwatts 500W PSU is fine. I don't get anything on the LCD, no signal at all. I don't get any beeps from the mobo, but a steady green LCD on the mobo itself. Asus tech support says I may need to flash the bios or replace the bios chip. I don't know where to get the bios replaced, or know how to flash it if I can't get to POST. Any recommendations? Again, this was supposed to be a very affordable PC for a friend, not for gaming, just email, web, and Office type products. I also pulled 3 of the 4 512MB memory chips. Thank you.

But in order to update the BIOS you need a CPU that's working on the mobo. | Report abuse Karch_32 June 17, 2011 10:06:26 PM Thank you for your reply. I have a 775 computer that works, so I hesitantly started swapping parts. CPU change didn't work, but apparently the memory is bad, as I put my good OCZ module in and it fired up. BTW, the CPU's get warm very quickly. | Report abuse jsc Motherboard Master June 18, 2011 12:32:12 PM That's why you do not run them without a heatsink. | Report abuse Motopsychojdn Motherboard Authority June 18, 2011 3:14:08 PM Nah, show him the vid http://www.youtube.com/watch?v=33ww-ZTV2FM&feature=play... this is why processors have heatsinks on them Moto | Report abuse Karch_32 June 28, 2011 12:41:02 AM Best answer selected by Karch_32. | Report abuse Register or log in to remove Ask the community Publish Tom's Hardware>Forum>Motherboards>Bad bios, how to replace or flash without POST> Related ressources: ForumBad BIOS flash , no post , no display!!
