Video starts lagging after about 10 minutes?

So, I’m dealing with a real headache here—my laptop starts crawling after about ten minutes of use. The biggest issue is that I can't even get through a decent movie in 720p without it choking; meanwhile, those tiny 300 MB series episodes run just fine all day long. Even on YouTube, anything above a grainy 480p resolution causes the whole thing to stumble and stall. My setup is a Dell notebook running an Intel Core 2 Duo at 2.00 GHz, paired with 3 GB of RAM and an Nvidia GeForce 9400 m.

Here is what I’ve already tried to do to fix this mess: I ran a disk defrag, performed a full antivirus scan, purged all the junk files from my hard drive, and gave CleanMyMac a go. What can I actually do to get this machine capable of smooth playback again? 🙂

What are the CPU and memory usage levels right at the moment things start lagging?
Maybe try reinstalling the Adobe Flash Player for whichever browser you're using.

I’ve already gone through the trouble of reinstalling Adobe Flash Player, so we can rule that out as the culprit. The issue is that my CPU usage spikes to a full 100% the second playback starts. What’s particularly telling—and frankly, a bit baffling—is how differently these players handle the load. I can get about five or six minutes of smooth sailing if I use VLC Media Player, but the moment I switch over to GOM Player, the whole thing starts choking immediately. It feels fundamentally off that one works while the other struggles right out of the gate 🤷

Players all handle video decoding differently, so you're gonna see different resource usage depending on how those devs wrote the code. Honestly, that Intel Core notebook seems way too weak for anything like HD video🤷

Honestly, that Intel Core notebook sounds pretty underpowered for anything involving HD video.🤷

But I don't get why it manages to run just fine for about 15 minutes before it starts stuttering. 🤷 If it were truly too weak to handle the load, it would struggle from the very first frame, but instead, I get this window of smooth playback before everything falls apart.🤷

Just keep an eye on the RAM usage in Task Manager while the video's playing. You'll see what's actually going on then...
