Did my HX750 bite the dust?

post #1 of 7
Thread Starter 
Hey guys, little stumped here...

I purchased a new sound card today (Xonar DX) and powered down my computer to install it. The installation was without issue but I have since been unable to get my system to power up. I think I have tried everything. I have re-installed all my parts to see if something wasn't connected properly, mobo isn't being grounded, all the plugs are secure.

One thing I have noticed though, is that whenever I flip the switch on my PSU on/off (I always flip it off and wait a few seconds before disconnecting the power cord) there is a lot of buzzing. Every time I reconnect the cable (despite the PSU being off) or flip the psu switch back to "on", there is a long buzzing noise. When I hit the power button, everything in my case powers on briefly (fans spin for 1-2 seconds and then everything shuts off) Is it my PSU or something else entirely?

I'm not speaking from experience, but is the power cable plugged into the sound card?

Yes it is.

I actually don't know what has happened, but after a few more power on/off on the PSU, my computer is working again.

Can anyone shed some light as to what potentially was the problem? I had not touched anything except for the power cord // psu on/off switch.

The Xonar DX uses a floppy connector right? Those things are easy to put in wrongly and make yourself a short. I advise pulling the soundcard for now, and seeing if that fixes it.

It actually uses a 4pin<->molex connector. I tried it earlier both with and without the Xonar DX to no avail. I still don't know what I did to fix it, but I am glad it is working! The electric buzzing noise from power supply on/off isn't something to worry about right?

That buzzing usually signifies dirty current OR a loose power cord.

Thanks for the reply! I do get a slight bit of wiggle room with the power cord but it feels firmly inserted. Assuming that it isn't the cord, is there a way to "clean up" the current?

I don't really hear the buzzing until I have to plug/unplug the PSU, so logically speaking it should be due to the power cord being loose. However, it seems odd to me as there are times when it is firmly connected to the PSU but there is still no signal of life whatsoever.
