At the weekend i finally got around to installing new processor (E8400 - Core 2 3GHz), in preparation for moving to windows 7.
Once I had put the new cpu in and installed fiddly new cooler (OCZ Vendetta) the system started, all lights fans etc on and beeps sounded normal but there was no signal on the monitor. I realisd that I had forgotten to flash the BIOS to support 45nm cpu's so put the original processor back in (Intel 640 3.2GHz) and although the system POST's and I can acces BIOS, windows will not boot.
Tried normal mode (gets to splash screen) and tried safe mode but the PC just powers down. There is a diagnostic POST code 7D (I think - will check at home). I got the CMOS error screen and also if I linger in BIOS too long it powers down.
I want to flash the BIOS to rev 15 and obviously can't do this via windows, going to try and do it using XP cd to acess drives and flash using AWDFLASH utility.
But I'm not familiar with this so can anybody give me any advise on doing this procedure?
Also, any ideas why it won't boot with old processor back in?
Possible board fault?
I recently ran memtest for about 11 hours no errors and have run sandra soft 2010, also no problems to check the current system.
Here is my system spec:
Intel Pentium 4 640 CPU 3.2GHz (moving to E8400 Dual Core 3GHz)

2 x 1GB OCZ DDR Dual Channel RAM 533MHz OCZ25331024VP
2 x nVidia 6800Ultra GPU's running in SLI
1 x Western Digital Raptor 74GB HDD (SATA) (moving to 150GB Veloci-Raptor HDD)
1 x Maxtor 300GB HDD (SATA)
Cooler Master RS-A00-ESBA 1000W PSU
Running Microsoft Windows XP SP3 and Direct X 9.0c
