I've also read that it could be caused by a bad HDD. I doubt it went bad. And don't have any spare HDD to test.
One more thing I'd like to mention is that it isn't detecting anything through the flat flex cables. Not my HDD, DVDD, etc. This could be an error in my Bios I'm thinking.
It is a AMD Athelon PC / Dual Core.
I'm stumped. It's been like this for over a month, and it's my fastest PC.
Anyone have any ideas I should try?
Also, this is a common error on Laptops. And many people resolved it by thumping it on the bottom with a hard object. But this is a PC, and I don't think that idea would work very well.
