If your computer boots up fine, it should be be the bios battery. Flashing with the wrong bios usually makes your computer completely unusable (showing only a black screen), so I think this is not the case.
You will need a CR 2032 lithium 'button'-battery. If you havent got one lying around, try a local radioshack, photo supplies shop or watch shop.
Replacing the battery is pretty simple: remove all the computer cables, open up your computer (touch a metal part of the casing first to rid yourself of any static), locate and replace the battery on the motherboard. Put it all back together and voilà.
(the first time you boot up again, your pc will give another checksum error, but you should be able to set the time. On the next bootup, there should be no 'checksum error' message, and the time should be correct)
You can find some extra info on here:

Examine the setup options to see if there's a failsafe mode or a BIOS reset/restore. Otherwise contact Acer tech support to see if they can provide a BIOS reset. You may have to send it to them. Older motherboards had BIOS on a 28-pin socketed chip called an EPROM. These could be ordered from various suppliers with upgrades, etc. I have not seen these in use lately.

Q9550 With Acer EQ35M MOBO

It is very likely that you simply do not have the right BIOS setup for the new processor. You will likely have to flash all your bios to get the new processor to both be recognized and to be able to recognize components on the motherboard. That is quite a jump in technology and it may be that the motherboard simply will not support the new processor period. In that case, be VERY careful buying your new board and make sure it specifically supports your processor. Sorry I could not be more help!
