Mobo: asus p7p55d-e
Recently my psu died, and after replacing it my computer functioned OK. However if I attempt to enter BIOS, the screen is littered with random characters amongst some of the usual screen.
I figured it meant it was corrupted in some way but for some reason my computer still posts/runs fine. I have cleared CMOS, hard reset, flashed a newer BIOS using asus update. when I try to enter bios It sits at a screen flashing with characters in a somewhat loop, and if I press a key it boots me out, says 'CHECKING NVRAM' then boots into windows.
Please see the images as I cannot really explain the situation.
What stumps me as 1). why does the computer still boot 2). why does reflashing not affect it
So im asking your wonderful community for advise on how to / if I can correct this situation, as all values are at default and RAM etc is running at 600MHZ when it should be at 1600MHZ, which I would like to correct. Also is it time for a new mobo
p.s. the motherboard generally slightly overclocked the RAM and CPU automatically.
