Very much at my wits end here. This noise is driving me bonkers.

I have restarted, closed every program, run virus checks, trojan checks, malware, spyware checks, cleaned my registry, restarted, haven’t added any new hardware or software and I still cannot figure out where this noise is coming from. If the speakers are off, simple – no noise. The time in between the sound varies, sometimes it’s 2 seconds and other times it can be 10 minutes. It sounds like a CHING, cash register or photo snap noise. Happens even when I have nothing open and just there @ the desktop. I know I’m not back doored so nobody has my webcam open and is snapping photos or anything like that. Anybody have any clue as to what this annoying god awful noise is? I can’t listen to anything (videos, music, etc) because the noise adds itself right in there just to bug the crap out of me! There is no noise @ startup, & yahoo, aim or any other messenger is not open and the noise still goes on. HELP!
No screensaver running and it does it all the time no matter what is open or closed, program wise. i have run every anti spyware program out there well …almost and i have no clue where this noise comes from. Was hoping someone else had this happen and could give me an answer.

I know i downloaded one on my old computer that basically scanned my running processes, startup programs, installed software, hard drive, registry, etc. It allowed me to modify the appearance of my PC (via system files) as well as control whats on the installed programs list. IT allowed me to delete and process of anything i wanted to as well as identified potential virus and spyware threats (And delete them whether they were or not), my computer has 2 gigs of ram but is TOTALLY clogged up and i need the program to just wipe all the crap off it from deep in the computer as oppossed to trying to get XP to do it. I believe the program was freeware, does anybody know waht it was, or one like it?

Okay well i bought the laptop about 5 days ago and its excellent but on every computer at first it runs fast then it runs slow …when you restore a computer it runs so fast and then slows down again which is my problem.. okay well before you guys give suggestion i ALWAYS do a disk cleanup everyday and a degrag once a week and i tried CCleaner like sh*** and ive bought Summit Soft System Tech Vista which gets rid of a lotta crap but still whats wrong with my intenet why does it slow down after about a week and i have Optimum Online with a Linsys Wirelss N Router. is their any secret files that i can clean in the Registry and their barely any programs on here so its very very cleaned out and its a 200GB hard drive and 3 gigs of ram runs smooth but i need help with the internet problem ..please give me some tips and trick thanks i appreciate it !! : )
And i have IE, and ive tries Safari fast but sucks cause doesnt work with java, tired firefox does the same thing as IE and ive tried Opera …they all dont work

I need a Windows 7 cleaner that does crap removal, registry integrity and maybe some performance boost. And please provide me with a FREEWARE cleaner. I really want to know what is the best FREEWARE cleaner for Windows 7. And please don’t provide me with some cleaner with trials and all that, i really want to have FREEWARE cleaner.

I know the scans are free, but the programs are not. I need to get my computer to run faster and clean it up with al the crap. But after you get the free scans and they say you have all these problems, they tell you now have to buy thier program. Is there something out there that is totally free beyond the free scan, that will not harm my computer
