Zotac GTX 580 problem (red lines in BIOS and dead GPU)

[faccione]

Hello all, like subject I have some red dots (almost lines) in my boot page (the motherboard one) and on my BIOS page too.

Problem started some weeks ago when I was playing videogames and then monitor became black, than shut off, black again and then popped out "driver stop working".

Now things became even worse since by using the "GeForce Experience" tool i don't even see my GPU... nor with other software like AIDA, Gigabyte one and several ones; seems my VGA is almost dead but if I go on administrator tools I can see in my hardware list that OS recognize "Nvidia GTX 580". If I go for further informations it says that it got a problem (error 43) and, more important, it says it's on a PCI-E 1.0 instead of 2.0.

I changed PCI-E slot, cleaned the VGA, updated motherboard BIOS but nothing happened.

My last chance before trashing it's this guide.

Do you think I can get any result by flashing the BIOS?

Any tip will be accepted.

Thank yoooouuuuuu

Sorry, but flashing the bios don't fix hardware failures...
