Windows Start Up Error

Hello! Everytime I start up windows after i log in, there is a windows critical error sound that i hear. It is the sound that you would hear if a warning window or notification window were to pop up. However, nothing pops up. All I hear is the sound. I don't know what is the problem. Can someone please help me out? Thank you.

 

New Hardware detected?

USB device(s) powered on?
USB cables securely connected?

BIOS "beep: codes checked? http://bioscentral.com/beepcodes/awardbeep.htm

 

in response to the replies, yes, all cables are secured etc.

i have copy and pasted the flagged information from the eventlog. I found these 5 entries at about the time I rebooted. Here they are:
