1. The drives are not in DMA mode. Read http://winhlp.com/WxDMA.htm
Yes, this can cause your issue!
2. Some USB devices are known to cause this. What's in the USB ports? Can you disable all USB ports in the BIOS for a test run?
3. Changed Mobo's
I don't see what motherboard driver package you used.
Here is the deal my brother just gave me his old intel D Dell computer as a back up I believe it is a Dell Dimension 1100, but I could be wrong (he changed cases). It already had an 80 gig Hd in there that has all the windows files on it. Well I took my other 80 gig drive full of music and put it in there because I plan on using this PC for storage. So today I go to play some music and for some reason the songs are kind of skipping. Every few seconds you hear it studder and it is getting really annoying now.
I ran Hitachi Check software to see if for some reason the drive was corrupted but it came back as OK. Here is what I have done already
Hitachi Fitness test
A few different Media Players
Closed everything running in the background
Tried 3 different sets of speakers
Changed the PSU figuring maybe the HD's were under powered
Tried 2 Sound cards one was a Creative and the other was Chaintech
Seperated all the Music on their own drives, the OS has its own HD and
and the programs are on a seperate
I cant count how many different Media Players I installed and worked with
changed electrical outlets and Surge Protectors
Put an electrical filters on the wires
Updated all firmware and drivers
Ended up formatting ALL my drivers and reinstalling windows
Changed audio acceleration settings
Shut off all Windows theme's
disabled onboard sound
every single codec got checked for updates
3 difference AV's ran
Bought all new fans, Including a Zalaman CPU Fan and Heat Sink (figured Maybe the CPU was over heating
None of the above fixed the issue, so I really dont have a clue what else I can try, any ideas?
Oh here is what makes up the PC
NEC DVD Burner
NEC DVD Drive
2 Hitachi 80G HD's
Intel Pentium D 2.54 Processor
250 Watt OEM Dell Power Supply
Onboard Audio and Video
Ok I took my digital camera and recorder what it sounds like. You hear the skipping sound very well, now when you hear it skipping all I'm doing is moving my mouse and opening up a different folder. The only programs open are Evil Player and FireFox NOTHING else. So I hope this helps.
Here ya go................and the Beatles happen to be my favorite band so HUSH UP all you haters (jp).
