Updating Bios in some old computers will either work or not.
I think is Bios compatibility issue M8. I hope I am wrong.

thanks for your reply salami, but bios flash was my last resort i was having these problems before i flashed bios (cmos/battery aint holding any memory)the only thing i can add is bios shows updated flash f5 but with the old firmware date.and windows shows the old firmware f2.as i said in my last post will only post if i completely remove battery! then can get into windows by pressing f1.
