Hi everyone!
Here are the specs available
HP tx2z-1000
Windows 7 64 bit
AMD Processor

The HP assistant notified of a BIOS update, clicked to proceed with the update. The update started, the system shut down and now it will not boot. The hard drive doesn't spin and the post codes indicate that the CPU failed. (num lock and cap lock LEDs blink once per interval). I've tried to reset bios by removing battery &cmos battery, leaving it out for 30 + minutes, plugging in the unit and powering on. Same led codes. I'm having a hard time wrapping my mind around a bios update frying the CPU. Has anyone else had this experienced and what was the fix? Was the CPU really fried or was it a bios reset?

thanks in advance!

The BIOS update did not complete and so I think the problem speaks for itself: the BIOS is corrupt.

So the best thing to do would be to flash the bios..... Which I've never done.
Any pointers?

well you did actually, but it failed ,a bios update is the same as flashing the bios ,it didn't fry the cpu ,what it did was corrupted the cmos chip containing bios[ bios = basic input output system] information needed to boot the computer ,
Is this a desktop or laptop computer

to quote an old quoter i read many yrs ago ;
"the bios is to a computer, what a pair of skates are to a skater" !

I advise people to never update any drivers or the BIOS unless the update fixes a problem they are experiencing.

In the old days, the BIOS was updated from a bootable floppy disk or CD. The update tools were very reliable, and the update could not fail due to a software fault. Today, people are so obsessed with having every driver and the BIOS updated to the latest version that Windows-based BIOS updating tools are used. If Windows messes up, the BIOS is corrupt and the computer is unusable, as you discovered.

Although your advise is well meant, I have had way to many issues with Windows involving older drivers and BIOSes. When I went from Windows XP to Windows XP SP1 I received a prompt BSOD from Windows every time. It took me 15 installs later to try a BIOS Update that really didn't mention any fixes, and guess what Windows booted up and everything was kosher. So as stated by Microsoft and other Vendors it is always recommended to have all your drivers and software updated before upgrading to a new service pack, due to code introduction that can change how windows communicates with hardware and software. I now make sure all my machines are 100% updated with everything, and I have had no issues.

Same here, i also prefer keeping the drivers and software up to date and maybe BIOS.

i have to agree with ITi on this one ,for me anyway , i bought my first computer in 1996,and have owned many since then ,i took a computer repair course in 1999 opened a small repair shop,it since closed but i fixed 100's of computer then and since ,install xp sp1-2-3 .on so many computer over the yrs,and now win7 sp1 ,and have never had to flash a bios to make one work ,did flash a bios once on a old machine with the floppy utility just to say i did it ,having said that i have seen computer that need a bios flash to work ,but that was at a computer repair shop where i hang out ,and someone else did the flashing .
and i only update device driver on my own computers if it needs it to make it right !
