Hey,
I recently bought a i5 3470 and it seems that I can't launch the computer. I've read that I need to flash my bios. I have this pre built trashy computer Packard Bell iXtreme m5850 and I simply can't find the model of the motherboard. I found that Acer Aspire m3970 and Gateway dx4860 has pretty much the same mobo but I'm not 100% its the same one.
Could anyone please enlighten what kind of mobo I have, and does it support the ivy bridge update?
