bios problem

[*the jaffa*]

I think my BIOS may be corrupt.

Basically I've been getting the BSOD recently, so I decided to drop my clock speed down in the BIOS to it's default speed (my PC has been overclocked for about a year now without any problems).

After having done so, the PC will now not boot up. I have reset the BIOS via the jumper pin and by removing the CMOS battery (I have also replaced the battery with a new one) but it will not boot up.

It posts sometimes (and sometimes not) and then says "CMOS Checksum Error, Defaults loaded press F1 to continue or DEL to enter BIOS."


Problem is, which ever button I press, nothing happens - I can sometimes get it to enter the BIOS but instead of the BIOS screen I get a cursor in the top left corner of a blank screen. :/


If any of you can help me, please don't use too many technical terms, I don't know a great deal about PC's.

I have a Gigabyte Ga-8n-sli motherboard (I don't know which BIOS version I have, I've never changed it) and Windows XP sp3.

Thanks

Hello and welcome.

The first thing to try is a new BIOS battery.

I have also replaced the battery with a new one as I mentioned above.

I would at least try another battery, it is not unknown for these batteries to be dead when supposed to be new. We don't know how long it has been on a shelf gathering dust somewhere.
Everything at the moment points to the battery being the fault.
So obtain another, and if possible, from a different supplier.

Yep, from past experience, rule out the easy bits first. If that doesnt work, I have a few ideas.

Hi - Ted - Dont really know if this will be help as its my first post here.

The CMOS Checksum error dosent necessaraly mean the fault is in the CMOS even though what has been sugested above regarding the battery is the usually the first and best thing check.

CMOS checksum error msssage (from what i can determine) can cover a multitude of sins.

Rumaging around on line through other Q&A forums it would seem that it could be any thing from CMOS battery to any computer part you can name even including a virus. The general concencus to faults as described by you and those who have experanced the same symptons and have been overclocking is replace the Memory Module - also check the keyboard as you say buttons dont work as others had the same problem of not being able get responce for key press. Some even had the keyboard connected to the wrong socket i.e. mouse to keyboard and viasa versa.

Hope this helps in some way - but i will keep looking Mike
