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.

Sorry guys, details will be a bit sketchy on this one, since this isn’t my computer, and my friend knows very little technical stuff about the one I’m trying to fix for them. Basically what I’m working with is that it is a Dell Inspiron 3600 desktop (Im assuming about 512 MB of memory, 1 G if we are lucky). It was shut down incorrectly and now is not able to get past the blue screen, even on safe mode and last known good config, all options fail and hit the blue screen. The only errors I can bring up are multiple 0X00000000, which, as far as I’ve ever worked with means the BIOS and CMOS is completely screwed… Now the interesting part, no new hardware or software, just shut down badly. I ran the Dell diagnostic disk and got the following, which I can’t apply a resolution for:
0f00:0244
Block 26639166

0f00:1a44
Block 26639166
Any ideas for how to bring windows back up, (they have files they didn’t back up anywhere else that they need, so wiping the hard drive isn’t an option). Also no XP disk is available.

Hi

i finally could remove the Vundo trojan using avast… now i guess im clear, nothing suspicious in the register or system32 or windows, etc…

BUT after i removed it, i said i need to repair windows (using the windows XP CD)… after the repair, some things began going weird:

1- i have no sound. At each boot, windows says it found a new hardware (the "Realtek High Definition Audio Device")… i got the driver for this on a CD, windows begins to install it and copy files, then says "installation of the device fails"…
2- i got an ATI Radeon X1950 pro which has a driver and a control software… the driver is OK, but then the control software (MOM.exe) takes much CPU time and so do csrss.exe and vsmon.exe (zonealarm)…
3- when browsing a CD, opening some folder then another etc… and then using the "Up" button to go to the parent folder, the path shown in the address bar goes like C:\Documents and Settings\User\Local Settings\Application Data\Microsoft\CD Burning\setup where setup is the folder inside the CD… this problem doesnt show up when i browse into folders on my drives…

I dunno if these 3 problems have to do with Vundo being removed or with the windows repair (i think it’s the first time i do a repair since i got my computer 6 months ago)… or maybe the combination of both…

thank you for ur time reading what i wrote… any ideas are welcome.. the 3rd issue is very secondary as it doesnt affect anything im doing, so u may want to forget about it, but it also may give u a clue…

everything else looks normal.. no CPU time consumption, no suspicious processes, no viruses/worms found by either adaware or avast, browsers and other applications run normally…
I just tried to reinstall the CCC (catalyst control center of ATI), and when the installshield begins to copy files, at each step i get a dialog saying "incorrect command line parameters

windows installer V 2.00.2600.1106
Copyright 2000 Microsoft Corporation. All rght reserved.

i can only click on an OK button, and i need to do that like a hundred times until the install shield completes (i keep pressing on the Enter button)…
about the CCC (MOM.exe): i have noticed that this process causes a consumption of the CPU time because it is being constantly restarted (like some other process keeps it from starting normally)… im saying this because the memory usage of MOM.exe keeps on swinging between something like 200 Kbytes and 8,000 Kbytes… at the same times, csrss, vsmon and also zclient use up to 60% off the CPU time until i kill the MOM process…
