Motherboard Dead

I have a L7VMM2 with 128Mb RAM, AMD 1.6 Ghz, 40 Gb HD Samsung 7.200 rpm, Lan, Video On board, 450W Power Supply.

It had Phoenix Bios (Award) v. 3.0 but it is printed on motherboard "L7VMM2 v. 1.1".

I tried to flash the correct bios from ECS site running AWD822A Utility and after that the motherboard came dead.

I remove the the RAM and the board beep.

I tried to get a Checksum Error by shortcutting the 2-3 Bios pins and with this I was able to reflash it (yet with awd822a) but after reboot the board was still dead.

I shortcut again the 2-3 Bios pins and I was able again to bootblock this time running UNIFLASH Utility with the "-E" parameter.

After the 2nd beep I had the power supply interrupted, before the flash completely done.

Now I can't even shortcut the Bios pins. If I remove the RAM the board doesn't beep anymore.

Please, any help or advise will be welcome.

Hi

If your bioschip sticks in a socket: Have it reflashed externally

If not, buy a new board, because having it repaired is usually more expensive.
If you are thinking about desoldering the chip yourself, you'll will need professional equippment for that.

When your board beeped without the RAM apparently the board was recognising the CPU, and the CPU was looking for the RAM. Try clearing the CMOS, and if you get back to the looking for RAM beep again, put in the RAM and see if anything changes. If you get a different beep it may be looking for video card, which would be a positive sign. See what happens at this stage when you plug in a video card (unless video on mainboard) and monitor. If still looking for video beep maybe a bootblock BIOS is operational.
