just recently my computer started acting up on me. whenever i "restart" the computer, it will not restart and just make beeping noises for 20 seconds or so and won't boot at all. i turn the computer off and then i have to wait 20 to 30 minutes before booting up my computer (if i try turning it on before then, it will make those beep noises and won't boot). i thought the hard drive was the problem so i went out and bought myself a new hard drive but am still having the same problem. so now i know that the hard drive was ok...what can it be? i'm not really good with computers and any info/comments would be appreciated.
