My tower has an MSI K9N6PGM2-V2 motherboard with onboard graphics only, with a VGA output and an AMD processor with dedicated fan. A few days ago on boot up the screen out went scrambled (see image below). A ctrl-alt-del reset seemed to fix it but on the next boot up the same problem occurred again but no recovery. Any ideas what to do to fix it? If it could be the graphics then I will try to get a new separate GPU as I could do with getting at least a DVI output for my current monitor. Additionally if I plug that into the available PCIe x16 slot will the CPU recognize it or just continue using the crappy onboard one? I confirmed it's not the monitor by trying an old monitor, which has the same problem.
