I tried to update BIOS for the first time and probably did it all wrong. I tried updating from version 1502 to 3602. What I did wrong is trying to update from the .rom file located directly on my hard drive, which obviously is formatted as NTFS, not fat32, also didn't load default settings (F5) before updating. I used EZ Flash Utility in BIOS. The Windows doesn't boot now and what I am getting is "reading failed" message on the screen when my PC automatically loads EZ Flash Utility after reset. I tried to recover BIOS from backup file and by using original ASUS motherboard CD but to no avail. Also tried resetting motherboard by removing CMOS battery and moving CLRTC jumper. I am kicking myself for stupidity now, please help me quickly if you can cause I need my computer to do some work and the deadline is close, do not know what to do, sorry for my english. Thanks.

Best solution

Does it boot even to BIOS? If so put the BIOS update on a FAT32 flash drive and try

Thanks for the advise. Yes, it booted to BIOS and I managed to update it with 3602 version again (placed on FAT32 flash drive). At least I can boot to Windows now but I noticed that the machine is slightly lagging, couldn't start skype and there is a message "motherboard error 3" just before Windows starts to boot - don't know what to think about it, is there a way to test the motherboard/BIOS for stability??? Perhaps I should revert back to version 1602??? Some people say you should not change whatever is working so maybe I shouldn't have tried to update the BIOS in the first place, lol.

With the BIOS update, everything will be at default, if DRAM is 1600 or better, go into BIOS and enable XMP and select profile 1, if you had an OC on the CPU will have to do that over also - any changes that you made previously will need to be re done/re-applied

The next time you flash your BIOS, reset the settings to defaults, unplug the hard drive (to prevent the hard drive from flashing itself with the wrong firmware), and flash from a FAT32 filesystem. Hint: DON'T EVEN THINK ABOUT USING WinFlash FROM ASUS!!!

You saved my skin guys, good to have such a forum, even Asus technical support got lost when I asked and they couldn't find the right answer. The last thing - is there any better application to test motherboard/BIOS/CPU and memory stability than Prime95? I just want to make sure that the BIOS is properly updated and it won't fry any hardware in my machine. Thx :)

Prime95 primarily focuses on the CPU and a little bit on the RAM, but you can use it to stress the heck out of your CPU. I tested an OLD AMD Athlon 64 in Windows 7 (very unstable) and the computer NEVER froze AT ALL. I also tested a Intel Pentium CPU on both Windows XP and Windows 7. Don't even ask me how many times my Pentium computer froze up. I run Linux on it now and it has NEVER frozen up ONCE. Thanks Linux! No offense against ASUS.

I wouldn't even bother trying Win7 on an Athlon64, and guessing the Pentium is an older one also, prob doesn't meet the requirements for Win7

Even though they are old CPUs, Windows 7 can run on those processors.

That's on a PENTIUM!!!

No offense.

None taken, was guessing an old one as you also brought up the Athlon 64, they have Pentiums for even the 1150 socket, but you might have been referring to very underpowered Pentiums, they go back to 1993 or so

It is a Pentium D. Maybe we should start a thread about Pentiums!
