ECS RC410L/800-M (V2.0) won't POST/BOOT after BIOS Update

I'm updating an older system as a favor to my sister and I've run into an interesting snag I'm having trouble diagnosing. System Info:

- Motherboard: ECS RC410L/800-M (V2.0)
- CPU: Pentium D 945 (Updated from 805)
- Memory: DDR2-667 240-Pin (2GB) (Updated from 1GB)

PSU is good and HDD is good. It's worth noting that the system was running after the hardware update (CPU & Memory), and Windows XP was reactivated after the hardware change.

When attempting to boot from disc for a clean Win7 install, I would get through temp file loading, the windows splash screen would come up, and before it would begin loading windows or going to the setup prompts, I would get a BSOD with a STOP: 0x0000005c notification. After trying numerous hardware configuration changes (e.g. turning off peripheral ports) and continuously receiving the same BSOD, I read somewhere to update the BIOS and the problem should go away. Makes sense, it's an older Pentium LGA775 board.

Went to ECS's site, downloaded the latest BIOS update. Flashed the BIOS successfully. Upon next boot, I received a CheckSum error. Reviewed settings and reset the clock, and now what is happening is the system will not boot at all. If I do a manual CMOS reset, it restarts the Post-BIOS Flash problem (e.g. CheckSum error, fix clock, system no longer boots after clock update).

No POST indicators, no beeps. No BIOS splash screen. Screen is totally black. If I manually reset the CMOS, it will just recycle the beginning of the problem post-BIOS flash.

TLDR; Updated the BIOS w/ mfg's BIOS update and now the system won't boot. Manual CMOS clearing does not fix the problem. Help is appreciated :)
 
Write down settings before flashing.
if you restart after flashing and boot-up dialog says, "wrong checksum", then enter "F1" and do the settings in BIOS as they were before flashing it. GO TO "Advanced Setup" -> "Dimm Voltage Adjust Function" and set it to [+150mv] also you have to enable ACPI. Then save with "F10" and exit to restart.

ACPI is enabled. I do not want to increase DIMM voltage, the BIOS shows it at 1.8 already. The problem is, the computer does not boot now that the BIOS was updated. I can get into the BIOS only by manually clearing the CMOS. However, once I update the settings and hit F10 to Save and Exit, the computer persists to not boot.

Does it sound like the BIOS update killed the board? I've read that this happens often with ECS boards.
