How can you tell if a bios chip is going bad?

The reason I ask is my Gigabyte GA-7DXR mobo has been acting weird for about 2 weeks. During bootup I have been either: Not getting any video display on my monitor until the desktop screen comes up; the post and pool data screens will flash on and off until the desktop screen; or the post and pool screens are all garbled up to where the words cannot be read.

In all these situations everything seems to go back to normal once the Windows desktop comes up. I have no problems after that, just during bootup.

Could the bios chip itself be going bad? Is there any type of virus that could have this effect on just the bootup info screens and not affect anything else?
 
I'm no expert, but if it were happening to me I would be looking at the video card and BIOS settings. Somewhere it seems that the video card is really confused about what to do until Windows takes over the assignment of IRQ's, driver, refresh rates, etc.

I've had the BIOS fail on a few machines and with each one I had either clock problems or the BIOS would forget what hardware was installed. I changed the battery as was suggested then, but in each case I never fully regained the "same" BIOS function and stability I had before. If the clock and hardware seems to be the same I would not be too quick to look at the BIOS. Have you tried resetting the BIOS to default with the correct video (AGP\PCI) selected?

Good luck.

What you describe is not a BIOS problem. A BIOS chip is either good or bad . . . it can't be "just a little bit pregnant." 🙂 Your symptoms are a bad video card and/or drivers for same.
 
Sorry I couldn't resist. As pertaining to your question, maybe it's some kind of power issue where it's not getting sufficient power to start the monitor, hard drives and all the other components and once the initial thrust of electricity usage is over it starts the monitor without anymore problems? Or I could just be a moron and should possibly keep my mouth shut unless I know for sure what i'm talking about, but i'll go with the former so I can keep giving out useless information.😉
 
Thanks for all the suggestions!! I'll try them out and see if anything pans out. Any other thoughts or suggestions on yhis? If it is the video card, wouldn't it also happen at other times, not just bootup?
