I have an HP laptop g42-415dx and when i start it up the Caps lock light blinks twice and then I get a blank screen. The HP website states that 2 blinks means BIOS corruption.
At the beginning it was giving me 1 blink which meant CPU failure so i have replaced the CPU and now it is giving me 2 blinks. I tried removing memory, CD, hard drive, removing the battery, holding the power button for 1 minute and then turning it on. I also tried pressing windows and B key and turning it on for a bios backup but none of them are working, I just have a blank screen and that's it. What else could I try?
ADD: I want to add that before this problem I had an issue which was giving me a massage at startup "System Board OOA Product Information Not Valid" but i just clicked okay and it contuniued to Windows. However, after couple of minutes it would crash and give me a different blue screen of deaths.
