My sound broke

hi.. someone told me that I should post on these forums with my sound issues, since no one is able to help me! hopefully someone here can.

I have a custom built pc I built in 2008.
Umm, I am kind of computer hardware ignorant...so I'm not sure exact names or specs.

Windows 7, 64bit
nvidia nforce 650i sli mobo
nvidia geforce 9600 gfx
intel dual core 3.0ghz
8gb ram
350gb/350gb/500gb hard drives

I have 2 separate sound jack sets. Umm one is an independent card that has fried. It is a c-media 3dx or something. It's kind of old.

But the other jacks are my mobo jacks. In the past (when I had vista) they worked fine. But I started using the c-media card and now it's just static and choppy noise and doesn't play much, so I decided to switch back to my mobo sound.

In the past I used realtek drivers. I installed the hd audio drivers from realtek and my sound would work fine and dandy. But now when I install them, they don't even detect my mobo jacks.

I've uninstalled the drivers, reinstalled them, I updated my mobo drivers, I've tested several different sets of speakers and headphones. They all work with my c-media card, granted it is very staticy regardless what I use.

Am I doing something wrong or could something be wrong with my mobo?

Could this account for why my computer has been excessively sluggish, slow and laggy even after formatting all of my hard drives? (My system has been getting slower and slower for at least 6 months, so I know it isn't windows 7. I installed windows 7 because I thought maybe vista was the cause of the sluggishness.)

Ummm please help address my sound and possibly my sluggish computer issues..

thanks a bunch..~

Hi, I have no idea the make of the mobo so I assume that is in the everest report.
I followed those instructions and attached the txt.

Umm, in device manager there are no yellow ! marks.
I have reinstalled Windows 7 and formatted my hard drives twice since January.

If you could make help me diagnose why my computer is so miserably slow that would be better than the sound.

I mean, I can't even open multiple tabs in firefox or run games anymore. and in my opinion my computer specs are really good.

honestly I have no idea WHO to take my computer to IRL even if I had that kind of money. Geek squad? I dunno.

But anyway, thanks.

 

thanks.

Umm ok I have malware bytes, microsoft security essentials, windows firewall/protection and I did have avg but the trial expired and I never redownloaded it. I also have c cleaner, and I do a disk defrag about once a month. is that too often or not often enough??

I don't have many start up programs, I disabled most of them cause of the slowness.

also I run anti virus and malware every week and I rarely have viruses but of course have lots of random adware cookies and temp files.

 

Hi..

Is there an easy way to export my start up programs into a text file to attach or do I type them all?

I think my computer's issues are hardware related. There is nothing software wise that would cause my pc to act like this except for viruses and massive amounts of adware, which I do not have.

What are the steps I should take to determine if indeed it is hardware and what should I do to fix these issues?

PS: I gave up trying to get my mobo sound to work and just reinstalled my crappy c-media drivers.

 

Hi, I didn't even see that at the bottom of your post.

When in safe mode, it runs the same if not worse.

I don't edit my services or anything.

Should I just take my computer to someone?
I think it's my mobo or gfx..

If I had $1500 laying around I would just build a brand new one since now my stuff is semi-outdated.

I attached my startup list, which really has nothing of interest on it.
