Boot Manager & Beeps

Hey all, and thanks in advance for helping me or attempting to!

My laptop [Toshiba Satellite A305-S6905 (got it in 2007)] has been just recently, as in about a week ago, been constantly booting to the Boot Manager upon startup (actually, it literally started happening after I (thought) I removed a virus/trojan/malware from that cursed Farmville on FB spam). It's never done this before. I now have to select "Windows 7 Professional (Recovered)" even though it's the only option there. This laptop was upgraded from Vista to Win7 about 1.5 years ago. I understand from some other posts I've read that the Boot Manager popping up is supposedly a "good thing", well now it's just completely annoying and if anyone can help me put a stop to it, that would be great.

My issue doesn't stop there unfortunately
Also about a week ago, I've noticed continuous beeping noises after I select the OS from the Boot Manager and am taken to the "Starting Windows" screen. There are no pauses, there are no short/long beep combos..it's simply continuous beep, beep, beeps and they're never ending until I power off the laptop. Again, none of this started happening until a week ago, and up until then, everything was fine. I've cleaned out the fan units with compressed air, and any dirt/dust. I've been told to try to use an Ultimate Boot CD, but for some reason, my laptop won't boot from a CD (again, something I've never had an issue with before this). I've tried to run the Windows Memory Diagnostic and upon the automatic restarting, I get a black screen and the same loud beeping--no boot manager, no "Starting Windows"...just black screen and beeping.

I've tried researching the beeping but it didn't seem like any of the beep patterns matched my dilemma. I only found ONE post where someone described it as the same as mine..just back-to-back and was thought to be a memory issue. Any help is GREATLY appreciated. (Oh and sorry for the chapter book explanation..I can't help it. I'm a female and we talk a lot )
