I was getting lots of weird blue screen of death errors, and the computer wouldn't boot past the bios and eventually got bricked. This is similar to an issue I had a few months ago. I think this is considered a No-post error but I couldn't find any more info to diagnose the issue. But other than the power light and keyboard light being on, there is no response whatsoever from the computer. When I plug the computer into an external monitor, there is no response. The screen is working though because when I hit D+power on, I get the flashing lights. I don't hear the fan at all (usually it turns on when I boot up the computer) and the screen is completely blank. The power light will turn on, and the keyboard lights will turn on, but nothing else happens. The current situation is that I can power it on. So I reboot the computer and it won't boot up after that. The computer resets itself and is doing some kind of diagnostic test and it freezes in the middle of that. I was using it normally this morning and suddenly get an IRQL type error. I am having a boot issue with my Dell i7559 laptop.
