Some months ago my pc blue screened me frequently I would re-boot it and sometimes it would run and boot up into windows no bsod other times it would mess up the bios making it look like some kind of alien language and wouldn't boot at all.
I thought at first it was my graphics cards because my drivers and resolution would mess up. I disconnected my crossfire and used my other card in the second slot moving it to the first pci-e slot with just one card it worked fine for a week then I get the same problem again so I thought both cards were faulty as when I removed them the bios was now fine and could boot.
I purchased a new gfx card and re-installed windows 7 again everything was fine for a week but now it looks like the same problem again. Do I have to replace my whole motherboard cpu and ram now to fully avoid this problem or is there an easier fix? Currently new mobos offer nothing more than slighly faster speeds, talking about seconds which are requirements we don't even need but it may be the only way?
