Computer slow lately.

[yozki43]

Hello people, my computer started acting really slow some weeks ago, I noticed it while trying to watch 720p or higher quality video streams, which I used to watch just fine, so after tweaking around uninstalling and reinstalling flash and other stuff I decided to reformat my hard drive and do a fresh windows install.

So after installing Windows I decided to try watching an HD stream before installing the latest drivers, same issue, and updating the drivers didn't fix it either.

Now I can BARELY watch 1080p movies I download, some scenes make my computer stutter.

A friend told me it could be anything from the CPU to the RAM or the hard drive, so I guess I'm asking if there's a way to diagnose each piece of hardware?.

Thanks

EDIT. Silly me my specs would probably help:

Core 2 Duo E4300 @ 2.40 GHz.
Mobo G31M-S2C
4 GB of DDR2 RAM
Super craptastic 80 GB IDE HD :$

We need to figure out if you have a hardware or software issue.

On the software side it might be something simple like using a different codec, enabling hardware acceleration, or maybe a player or video driver issue.

To test your hardware run some common benchmarks and see how the results compare to similar systems. Also you might want to run Ultimate Boot and stress tests some system components.

Finally check your fans, especially your CPU fan and make sure it is working. A hot CPU will slow down...

What video card and how long have you had it?
What program are you playing the HD movies with?
Have you checked your temps lately? Check your fans and blow out any dust in the CPU heatsink.

Thanks guys! I have a lot of homework now, I'll run the Ultimate Boot diagnostics and check the fans.

As for my Video Card (Oops, totally missed it on the specs list), It's an HD4850, about 2.5 years old.

I watch my movies using Media Player Classic, but I have the same problem watching videos on youtube or watching streams on twitch.tv or own3d.tv

Check your temps, you may have an overheating GPU. It could have years of dust build-up causing the overheating.

You didn't mention which software you are watching the streams with.

You might also want to download VLCPlayer. It comes with a pretty decent variety of codecs but definitely get that card card out and give it a good blow out. Just remember to put your thumb on the fan so it doesn't spin around and burn out the bearings.
