Hello, novice computer user here. My HP m7330n is having a hell of a time booting up. It takes dozens of tries and sometimes upwards of an hour. This has been going on for weeks. (Meaning it's gotten totally ridiculous.) My latest guess was that my motherboard needs replacing. First, I have no idea how to do this and it sounds a little tricky. Second, I don't want to replace a large part if it isn't actually broken. A google search on the issue led me to this site and some threads about corrupt BIOS and flashing them to fix the problem. When my computer does boot up I have noticed that it says something like "default bios settings loaded due to checksum issue". I don't know if that's a clue or not. All I know for sure is that the damn thing is like a mule when it comes to starting. But the strange thing is that it will eventually start just by pusing the power button repeatedly...I don't know why. Anyway, do you think flashing my BIOS would fix my problem? If so, what the hell is flashing your BIOS? Can a clueless (but otherwise reasonably smart) noob handle such a task? Seriously, I could really use your input.
