My computer is fast, but when i play video or music, it plays it in slow motion. Any ideas?

'Out of the mouth of babes' Your PC is not fast at all that is why it struggles with video.

You can speed your PC up by buying a decent sound card & graphics card & adding another 2GB ram.

But you have a very old, slow hard drive so that will limit the speed too.

If you can afford it buy a new PC anything you get now will be better than what you have and won't cost much more than the upgrade.

Video's require quite a bit. A decent video card as well.

Perhaps update your video card drivers. If it's youtube you're trying to watch in 720P your processor might be hitting 100% useage , just hit ctrl/alt/del and check the cpu useage during youtube.

upgrade your flash player, just google, adobe flash, and udpate that.

try using VLC media player, it's very lightweight program.

try some codec packs.

music .... no idea.

512mb of ram could be an issue, i'd definitely grab another 512mb stick or even just 256mb stick.

streaming song and/or video clips takes a lot of ram, once you've too many courses operating or temps are crammed. it is going to reason this to ensue. with the exception of that, i could run each of the scans you are able to, a trojan could be using your puter without you understanding it, and using your ram and cpu. straightforward homestead cleansing could nicely be so as.

I'd reccomend you upgrade to a new computer or upgrade parts.

No dedicated graphics and a Pentium Fo....
