DV5-1235DX BIOS corruption failure

[IgorY]

So this is what happen

I installed Windows 7 and then tried to install Win XP on the second partition

of course it ruined my MBR but i got it fixed thru recovery console

then using EASY BCD added second record for XP

and booted back into XP Installation disk

During xp install when cpu was rebooting it froze

I got the HP logo and boot menu

Boot menu did not respond

So I tried plugging and unplugging and rebooting and a few other things

and nothing helped

Then found that BIOS has an update on HP site LINK HERE WIN7 x64

unpacked the .exe and put it on a usb stick

then tried the method listed here

http://forums.mydigitallife.info/threads/13095-Undocumented-INSYDE-BIOS-recovery-method

but nothing happen

so I wonder if win+b is the right command for flashing BIOS from usb

...still same old HP logo ..... and nothing

later on read this LINK HERE

Tried to remove all the attached hardware

now the HP logo is gone and i got a black screen

caps lock and num blinks twice according to this LINK HERE

the problem is "BIOS corruption failure"

as  i understand this problem, what needs to be done is bios repair

what should I do next

P.S. Really need those service commands to flash bios from usb

if the BIOS is corrupted then the only option is to change the bios, this can be done via a third party, which will supply pre-blown chips which must be installed yourself, needing soldering iron etc.... or you may be able to send the unit back to HP for repair.  I will have a look on the web to see if there are any other options w.r.t. attempting to resurrect your defunct bios chip, it is possible that you may be able to attempt the process again but unfortunately I think its a no go. Hopefully others with your system will "chip"....sorry for the pun....in with advice.  I will get back to you If I find anything useful........

ok  after removing the RAM and hard disk and restarting my problem has downgraded back to

FREEZ @ HP LOGO SCREEN like this issue LINK HERE

You could look at testing the RAM using memtest loaded on a boot disk,  I do not however know where the HP Logo comes from, i.e. Bios Software [which I suspect it may be] -or- HDD.  If the PC will not begin to load the O/S then were back to BIOS failure.  Have you any spare RAM you could replace the system RAM with to rule that issue out ?

Super late reply but just saw this.

Hang at HP logo could be to do with HD boot sectors.

I had this problem before. Fixed it by pulling out the HD, hooking it up to an adapter and running it as a master drive from my desktop. Used Windows cd to boot and deleted partitions and recreated. When you do a format after creating new partitions, it Windows should also create a small drive for bootup. From there install Windows as normal.

Hope that works.

I found the Answer to my Problem at Yahoo Answers. I Replace Hard Drive and same problem still appeared until I reset CMOS battery. Here is the answer I followed from Yahoo

If your computer is stuck on the HP splash screen or basically won't let you even start to load Windows it's very possible that somethings wrong with some of the hardware on your machine or the CMOS settings are bad.

Depending on how comfortable you are doing your own computer work, you can try some troubleshooting yourself by pulling the CMOS battery, which will reset your computer's BIOS (This process doesn't affect windows or your data.).

You may want to google pulling the CMOS battery for more information as you might have to open up your computer, alternatively, the battery may just be under a panel on the bottom of the laptop.

If you complete that and you're still having the same issue, you might be having hardware failure. You'd either need further troubleshooting, or you can just take your computer to a technician.
