And see how much to get it fixed. You've tried the usual but there are a few things that stand out.
8GB ram is too much for a dos based updater. Try it with the lowest amount of ram you can.
The 8800's are dying so use some other card if the update fails.
I'm going to assume you are using a small USB stick for the ROM file. I keep a 1GB stick around just for this.
I recently got this computer second hand, everything was fine for a while, but only 3 GB's of the 8GB's installed was available on Windows 7 Ultimate, and upon looking it up people suggest a bios update. I've done this before via the asus update software on other computers and have never had a problem. This time, the computer froze while updating the bios. I left it for several minutes and unfortunately nothing happened so I powered it down. Upon restart, the only thing that comes up is as follows:
Boot Block Compatible Version Ver.035
If you want to recovery from USB Device,
please do not insert any disc into CD-ROM and Floppy!!
Bad BIOS Checksum, starting BIOS Recovery...
Checking for FLoppy...
Floppy not found!
Checking for USB Device...
Reading file "P5WDH.ROM"
and it will stay on that for about 5 minutes and then power off automatically.
I've looked up and tried everything I can find. I have the newest BIOS .ROM file on a flash drive, renamed "P5WDH.ROM" inserted and it still does the same thing. I can't access the BIOS at all to change boot options, as this is the first thing that comes up. No Motherboard beeps, no bootlogos, nothing, just that. It's not the Motherboard Battery, as I've switched it out for another and then back (same thing both times).
The full specs of the computer are:
P5W DH Deluxe Motherboard
Intel Core2 Quad @ 2.4Ghz
Nvidia Geforce 8800 GTS
8GB's DDR3 Ram
500GB Internal HD running W7 Ultimate and WXP on seperate partition.
(Both OS's worked fantastically before my mishap)
Please help me ASAP, I'm desperate to get it back up and running.
