When i boot the computer what comes on the screen is (''award bootblock bios v1.0'' copyright(2) 2000, award software, inc bios rom checksum error detecting floppy drive A media insert system disk and press enter)

TRY CLEAR CMOS IT CAN HELP.

I would say you have a failed memory (RAM) module. Probably a module in one of the secondary slots since the computer is able to POST and will attempt to boot.

your hard disk is disconnecetedor loose . pls check the hard disk power cable & IDE or SATA cable. Then check BIOS hard disk detected or not if hard disk is not detected your hard disk is faulty.

Hai, That message dosn't sound like an error. i suspect the ram is faulty/incompatible and the pc won't boot because of it. 
Change back to the old ram and reset the bios (jumber on the motherboard)

Normally a bios checksum error is caused by a dead cmos battery. In a laptop that can be a pain - some are specialty batteries, some soldered directly to the motherboard, etc.

Start the laptop and enter the bois, there usually will be something to tell you what key to press, most of the time it is f2 or f10. Once in the bios set the date, time and boot order, then save and exit the bios. If it boots ok then try to determine what type of battery and it's location on the laptop to replace it.

If you let me know the make and model of laptop I will try to help determine that info and also where you can get the battery. That will more than likely be from eBay....

Hope this helps

Hi there.
Try clearing the cmos
<<<<< you will see in the picture a plastic jumper (in this case coloured green), move it to the other position and hit the on/off button, then put it back in its original position and power up the machine again. Hopefully the issue will have been sorted. If there is no jumper remove the battery for an hour and make sure the power cord is removed from the back before you clear the cmos

Good luck and thanks for using Fixya!!

You can try flashing/updating the BIOS if nothing works.

this is a common problem wirth asus motherboards the only thing is to re set the bios to do this romove the power plug from pc wait for 30 second - 1 minute for the static to be removed from board then find the bios battery and remove this then find the jumper that says clr cymos or bios then place the jumper on the opposite two then press on button then place jumper bace to orraginal possition then place the power cord back to tower psu then reboot pc then all will be fine replace battery in the holder enter bios then hunt for all relevent thing like first boot should be hdd then cdrom then floppy drive this is only if you have got one.

to set-up bios properly please e-mail me with your motherboard details and I'll e-mail you back with a list of things you should do to get the bios back to good working order.

The bios upgrade procedure stopped at half , leaving the bios corrupted. The computer now cannot do a regular boot procedure, this is the reason why it cannot recognise some device. If you are still able to boot from floppy, you can restart bios upgrade procedure from floppy. Just download floppy version upgrade and re do setup. Even if you do not find latest bios version, just download a floppy upgrade that is working, so that you can restart your machine regularly , and then do the update to latest version.
If you are not able to complete the bios setup, the only way to fix your motherboard will be flashing the CMOS chipset with a chip programmer device that will reinstall bios straight into cmos chipset.
You can have this done at the service point, in this case consider also replacing your motherboard.
