PC sound is very jumpy

by JJohnson / April 23, 2004 4:27 AM PDT

I built my own PC that had an integrated sound card. When I tried to play music, the sound would cut out at times and was not very clean. In addition, it appears to "strain" the system by making my mouse clumsy and flicker when I am playing songs.

I bought a SoudnBlaster card thinking the sound card on the motherboars was cheap, but I am still getting the same problem. I disabled the original sound card in the system Bios. Still a problem. Any suggestions?

Which SoundBlaster card do you have?

Which motherboard (and chipset) do you have? If you have a motherboard with a VIA or Nvidia Nforce chipset, have you installed the drivers?

Also, is DMA enabled on your hard drive?

My sound card is a SoundBlaster 16 bit card, not sure after that. I would have to look at is (not in front of it now)

The motherboard is one I bought at Sam's Wholesale, it is made for Athlon processors, for which I bought an Athlon XP 2100 processor. I have installed the drivers for both the original sound card as well as for the SoundBlaster.

I have never heard of enabling DMA - what is this and what do I need to do?

Thanks for your help.

Have you installed the chipset drivers that came with your motherboard? Like the VIA 4 in 1 drivers, or nForce drivers or the SIS drivers?
If you are not sure, what brand and model is the motherboard?

DMA (Direct memory access) mode allows data to be passed from the memory directly to the hard drive without passing the processor. Which helps speed things along. Sometimes the mode is turned on by default, however there are times that DMA is turned off. Also are you using an 80-wire IDE cable to the hard drive or the standard 40-wire IDE cable?

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
