A while ago my husband's laptop had a similar issue where it would beep and not boot. We then sent it to the manufacturer (hp) and they replaced the hard drive. Since then the warranty has run out. Today, out of no where when he started the machine it started beeping continuously and would then power off. I looked up the beep codes but there was nothing about continuous beeping. The computer then started turning off and on repeatedly not even getting to the stage where it would beep. The lights would turn on and the fan would start then it would turn off and repeat. After a while of doing that I got it into BIOS. I ran a memory check and a hard drive check. Both came up clean. I restarted it again and finally it booted after beeping about 30 times and me pressing the buttons on the keyboard. I think it might have had something to do with the sticky control key. I decided to check if it would be consistent and restarted it. Again it beeped about 30 times and after pressing most of the buttons on the keyboard it then asked which OS (of which there was only one) to boot into. It seems to be ok now that it's started but what could be causing this issue? The laptop is a Hp Compaq dv6 (I think) any help would be greatly appreciated. Thanks in advance.
