Audio Jack in front not working.

Question

Hi, when I bought my HP Pavilion p6823w Desktop PC, from walmart I hooked it up correctly.  When I booted for the first time, I got a Blue Screen of Death, and the problem system repair said it was my IPOD cord was plugged into a USB port.  Without the IPOD hooked up to it.  I couldn't boot up, so I ran the system repair.  the reason I didn't take it back to Wal-mart was because it worked fine without the Internet when I booted up again.  I also bought a Belkin Wireless N Adapter for my Router.  It worked fine with the internet. 
Please read the whole thing, because this is all relative to why my audio jack isn't working. Thank you.
Until I started using the internet for long periods of time, I received problems.
For instance, it would disconnect me from the internet without telling me on the bottom side bar, it would tell me it's still working, when I keep getting web pages that are telling me the Internet Server is not found.
Another instance, when playing League of Legends, my latency would go up to 10,000. This is not normal.
The third instance, it would let me still play the game, but have high latency and lag out eventually.
The fourth instance, I cannot download any files on the computer anymore, even if the internet is connected.
The fifth instance, my monitor when it goes to sleep, will only display the background image, without any icons.
This must be a hardware problem, if the monitor won't load the desktop icons or start menu.
To make it work again, I have to turn it off manually with the button, and turn it back on again. And then it works.
I didn't notice this problem till after the 30 days of returning policy to walmart, because I turned off my computer when I was done using it.
The sixth instance, I can disable the network adapter, and re-enable it to make the internet work for a very short period of time, with the same errors of not being able to display web sites.
The seventh instance, I reformatted my computer because I thought it was a virus that norton couldn't find. It still had the same problems, but after the first few days it started up again.
The eighth instance, I received w WinSAT repair, because my game was freezing completely for about one second or two seconds.
The ninth instance, I contacted HP Support VIA Phone, and they could not fix the problem.
I enabled High Performance Power Supply.
I reset the IP Address.
I cleaned my temporary files.
I ran Norton Anti-Virus, found nothing.
I ran Hijack This, a program to see what program files are being used.
I ran HITMAN PRO. Found nothing.
I ran firmware updates for my router, is was up to date.
I changed the settings to WEP after, to see if it was the router.
I checked all my other computers to see if it was the internet, it is not the ISP.
I also changed the network name, so the interference with temporary files, wouldn't interfere.
I used other browsers, and had the same problem.
Some websites would load halfway, and need a refresh.
I have not opened the desktop.
I tried exchanging the Belkin Wireless N Adapter, I had an older one I bought before, and when I plug it in, it doesn't recognize the device.
I re-plugged the new one in the USB port, and it worked for a few minutes before returning to the same errors of Internet Server Not Found.
I am confused, because it's not the Wireless N Adapter. My browser, my ISP, my router, my USB port, because the other's work and so does this one.
My reformat didn't work, and I experience this problem everyday, but now downloading files doesn't work even when all other web pages load. This means, there is something wrong with my hardware.  Because the other browsers won't download either.
I'm also using my laptop right now, to make this post, so my internet on all my other computers works fine.
I'm interested if there is a problem with the hardware when I bought the computer, because there is no real fix for this problem.  Each time I get on the phone with TECH SUPPORT, they ask if it's working. And sometimes it does, but then after a few hours it goes back to the same errors. I can't keep calling Tech Support, telling them it's not working when it starts working randomly, then going back to the same errors. Please help!
Also, TECH SUPPORT ignored my monitor problem.  They didn't say anything about how to fix this problem. I hate having to turn off the monitor and turn it back on because this is  a brand new computer. I still have the receipt, warranty and I'm tired of explaining the problem to different people from TECH SUPPORT.
Also, my audio jack in the front doesn't work.

Hi,
Did you burn a set of the HP Recovery Disks?  You mentioned that the reformat failed. Is that correct? Did you try a full HP Recovery?  If not, then backup your data to external media.  Boot up to the HP Blue screen and first try diagnostics and see how that goes.  If that is successful, then boot again up to the HP blue screen and try Recovery.
If you don't have a set of the HP Recovery Disks and the Recovery process fails from the HP blue screen then you need to order a set of the HP Recovery Disks from HP. HP Recovery Disks.
