On booting I got a siren sound and the error message "BIOS ROM CHECKSUM ERROR" the system is locked up. I cleared CMOS and windows has loaded to the point of asking for my password I get the error message "Pagefault in non-paged area. With a blue screen This problem seems to be caused by the file NTFS.SYS. I reboot get siren sound and the error message "Pagefault in non-paged area. with a blue screen This problem seems to be caused by the file NTFS.SYS. I reboot get siren sound and the error message " the system is locked up.

Flashback to two months ago when all of this started: I was online and I hear a grinding sound and the system shut down. I tried to reboot and the power supply fan started no beep and system was dead I tried again and the power supply went dead. I live in an area with frequent electrical storms and always shut down and unplug when it starts to storm. After buying a Cyberpower battery backup it indicated that only ONE outlet in the whole house is grounded! (the original wiring dates to the 1935.
I live in a rural area so I ordered all parts off the net, new 500 WATT power supply, new floppy drive, Refurbished Supermicro P4SPA+, S478 MB, a used Intel P4 3.0 SL7E4 PRESCOTT 478 3.0GHZ 1M 800 CPU. The system read my cdrom for while but has stopped reading that.

I tried to boot up but got the same checksum error. I tried to flash the bios with the new 1.3 bios , the MB had the old 1.0 bios. It went through the motions and flashed the bios but it still gave the same error. And then the system stopped reading the floppy even though the system still recognizes I DO have a floppy connected. I emailed and spoke to Supermicro techs and they suggested I order a new bios chip I did that and this is where we came in at the beginning, it still gives the same error messages and reads the bios at 1.0 even though I specifically requested Supermicro send an updated bios chip.

The tech suggested the siren sound was because the motherboard was rejecting the CPU but this is the correct CPU and its not overheating. I also checked by putting the "new" CPU in the old MB and the system was completely dead and would not even try to start up so I know the old MB was dead. The tech suggested my motherboard was faulty so I am going around in circles, I don't know what to try at this point. I took it to one repair shop and the tech didn't have the tools to pull the chip and did nothing. I took it to a 2nd repair shop and the tech pulled the bios chip and installed the new one. This town is small and I don't know how reliable any repair shop is.

The dealer on eBay did offer my money back on the board but finding an AGP 478 CPU board with 4 memory banks that accept 186 pin sticks is hard. I need that because of my video card and memory I have.

PS: Now when I try to boot up it starts and stops a few times before it revs up

This problem usually occurs when your motherboard battery cell gets out of order. Just change it.

I flashed the bios, then I put a new battery in the motherboard I had inadvertently put an expired battery in. This seemed to work at first it booted up without hesitation, indicated that I had bios 1.3, loaded windows and stayed on for 5 minutes then crashed to a blue screen with NO error message. When I tried to boot again it started the siren sound with a bit higher pitch and then the same BIOS ROM CHECKSUM ERROR was back. Then I started up hit the del key went into the bios and checked. It did not show I had a cdrom drive but everything else was OK. Then the keyboard froze up. When I tried to boot again I get the siren and BIOS ROM CHECKSUM ERROR.
