pc help

can any one help me im having problems getting into bios setting pc loads up and then stops on press f1 to continue or press delete to enter bios but nothing happens i,ve changed me keyboard which is ps2 and that hasnt made a difference and i,v tryed removing the battary but still no joy

 

i,v also tryed the jumpper settings too

 

What does it say before 'press F1 to continue?'

 

it comes up with cmos checksum error if that helps

 

Right. Is this a new PC build, or has it worked fine before?

 

it has worked fine before then i tryed to install a bootskin and its all gone wrong lol

 

Right. So the system doesn't respond to any key presses when it says press F1 to continue? Normally it should.

 

yep and i,v tryed all the above but still not responding

 

Unplug the PC from the mains and take the CMOS battery out. Leave the system for an hour like this, then put the battery back, then plug in the PC and turn it on.

 

ok bud i,l give it ago and reply later

 

hi tryed that in fact the battery been out for bout 23 hours but still no joy

 

Is there a 'CMOS Reset' Jumper for your motherboard? If so, have you tried it?

 

yeah tryed that to bud but still no joy

 

Hmm, your BIOS chip may simply have stopped working then. You can either buy another and solder it on yourself or have the motherboard replaced.
