I have an older HP Pavillion desktop (a406x) which suddenly stopped booting and will no longer even let me enter BIOS SETUP! When I turn it on, no matter what else I do (hit keyboard keys until my fingers fall off), it lights up the monitor with a blue screen with the HP logo in the center and "INVENT" below that, and then some geometric icons in the upper left hand corner (triangle, square, arrow, etc.)
Since I cannot get it to enter BIOS SETUP (usually by hitting the DEL key as you press start), I am thinking my BIOS has been corrupted - one of the users carelessly visited websites that have viruses, so, I am wondering if a virus could somehow clobber the BIOS chip? I used the jumper to CLEAR CMOS and then use DEFAULTS CMOS, but it made no difference. I disconnected the H/D's also - no difference - still that blue screen. Both the CD and DVD doors open and close, all fans spin up, and the floppy door opens but no attempt is made to boot from the floppy.
There is a VIA chip on the ATVBX-LA motherboard (I don't know the brand) with the number VT8237 - could that be the BIOS CHIP - I hope not because it seems to be soldered onto the motherboard and not removable to be replaced.
If anyone has any experience - please respond - any advice would be greatly appreciated.
I am wondering if this motherboard is still available, in case I have to replace it - overall, the various components seem to be in good shape, so, I would like to fix it if whatever part I need can be identified and obtained.
Thanks, guys.
