Can a virus fry a BIOS chip and can a BIOS chip be replaced without replacing the mother board?

I think that my computer may have recieved a virus that seems to have wrecked my bios chip because my computer will not do anything when it comes on. The only thing that happend is the fans power up and there is a little blinking dot on the top right corner of the screen. But if I replace the mother board or bios chip wont the virus still be on my hard drive so as a result wont the virus fry my new bios chip if that is possable plesase help me

    Have you checked your power supply to see if it is working properly? It may power up and seem like it is working, but it could be faulty and I had expirenced that happening quite a few times. If you have a spare one I would start there first. If no luck with that I would replace the Motherboard before trying to find a bios chip. You may find a board may not cost any more than replacing the bios chip.

    Good Luck

    who is to say it isn't a BOOT Virus, on the hard drive, or a BIOS virus, that corrupts the BIOS?

    Anyway, here is how a technician tests it:

    pull the AC power cord. Then, pull the BIOS battery, for about 20 seconds.

    Reinstall battery, plug system in, reboot. Or, boot from the LiveCDrom http://pclinuxos.com/

    That will tell you that the problem is with the hard drive, and it needs to be re-formated.

    Very unlikely that any virus has effected the BIOS on your motherboard. Turn of your system and unplug the power and IDE cables to your hard drive. If you have a boot floopy you can install that and power your system back up, and note what happens or doesn't. You can check the link below for POST codes.

    Well,,,,,

    You can certainly flash a bios by executing code so I don't see any reason why a virus couldn't be made to do the same thing.

    And if your bios doesn't load then nothing works.

    I have heard people insist that a virus can't damage hardware.

    Really? Why not? If the firmware can be updated by running code then why can't a virus be written to run code to corrupt the firmware?

    yes and maybe .. but it would be prolly about as easy to replace the board ... the virus may have gotten into the bootsector of the drive ... myself i would try an fdisk and reset cmos on the mobo, set first boot device to cdrom, and see if windows will load ... then maybe try a lowlevel format with a tool from the drive manufacturer .. before i replaced the board ... .. you can always remove the harddrive and just boot into bios settup using the DEL or F1 key at bootup just to see ... if u cant get into bios settup then theres a problem with the board itself ...

    I dont imagine you ought to modify the more moderen bios. you could remedy ur concern by using replacing the settings in the bios. If no longer you could replace the firmware on ur bios to a more desirable recent version. Bios is only a ROM which has some documents written on it. If in any respect that version doesnt matches to u, u can only erase the former documents to write down a sparkling one. so u dont want to regulate the chip. you ought to goto any Motherboard provider middle to get yout Bios ROM as a lot as date to a more desirable recent version.

    the only thing that can fry the chip if it,s exposed directly into a device that magnifies a micro wave, this will indeed fry it, but a virus can,t
