Components suddenly stopped working, then working again? What gives?

post #1 of 5
Thread Starter 
Hey guys, here's an overview of what happened regarding two components of mine: the GPU and soundcard. This whole thing started after watching some streams on said computer, with the last stream practically KILLING my speakers (i.e. loud, "crunchy" noise).

- Restarted the computer, and noticed that the VGA-LED light was turned on (note: using P8P67 Pro using the latest bios). None signal for any of my monitors.
>> Used a different GPU and all worked normally.
>>> Put back my main GPU in and all worked normally..

- Upon arriving to Windows, my soundcard wasn't detected (note: using ASUS Xonar DG)
>> Uninstalled and tried to reinstall the driver, but it couldn't find my soundcard.
>>> Re-seated the soundcard and everything worked.



The funny stuff about all of this was that the computer was working fine for months, then all of this started to happen. What the heck gives?

The weirdest part of it all was the soundcard -- when I was switching out GPUs, I never even touched the soundcard; it shouldn't have popped out of its socket. Yet it required a re-seat in order to get detected?


I'm suspecting that my motherboard is at fault here?

Feedback would definitely be appreciated. Thanks.

Chip creep

It happens to expansion sockets too.

Have you had any storms lately? I had a bad heat lightning storm a number of years ago, it gave the phone line a good jo;t (this was when I had DSL) and travelled through the RJ45 straight to my NIC and fried it. About a week or two later other components started to just give up or erratically work.

The motherboard theory pans out but how old is it? I ask because as silly as this is your CMOS battery may be faulty as I had a customer who kept having to reseat his NIC.

Hey guys, my bad for not saying thanks a while back. Much appreciated and reps to you two.

As for having any storms: nope! While the weather's been kind of weird (NorCal), it's nothing drastic at all.

As for my mobo, it's a little less than two years old. I don't know if anything has gotten fried, but a while back (i.e. weeks ago) I would hear something that sounded like a spark inside my case. It didn't happen often, and only lasted for a millisecond (i.e. very quick). I didn't care too much about it since everything was working.





Once again I'm stuck in the same dilemma, only this time... I'm quite confused as to what's happened. Here's a little play-by-play:

1. Listening to music from an app (foobar), close it, and notice that the last millisecond of it keeps looping (think of the sound you hear when a game crashes)
2. Reload the app, listen to a different song (which works!), then close it again and get the looping going on.
3. Shutdown the computer, but it freezes before completing.
4. Turn the computer back on, and notice that I'm getting the GPU-LED light goes up.
5. Re-socket the GPU, boot up, then notice my soundcard isn't detected... re-socket that afterwards and everything's golden.

**Note: in-between the loops and the failed shutdown, my GPU and soundcard were working -- clear images and sound was working.


Now here's the odd part: before I even shut-down my computer, the sound was working just fine -- if I wanted to get rid of the looping, I could just load up a new song (and if I closed the app, I would get the looping). But after I re-socketed my GPU, my soundcard wasn't detected until I re-socketed that as well. Note that I never even touched my soundcard when I was re-socketing my GPU.

So here's what I'm thinking: the GPU and soundcard, which are the only things occupying my expansion slots, are somehow being pushed away from their sockets. One thing I'd like to note here is that my case, an Antec 900, requires the need to push the brackets just a tad bit in order to get the screws in. However I've always had to do this, and I've never had a problem with my computer for months.

I guess the last thing to note is that my computer gets a lot of sunlight since it's near a window, though during this time it's not really hot...

While it's looping, open task manager, click the CPU column until the processes are listed in order of CPU usage.
Note what's there and then do the same after you stop the looping. That may lead you to what's causing the problem.

You could also look at Event Viewer.
