I’m not entirely sure what’s causing this, but my laptop has become almost unusable lately. It’s reached a point where I can't even run 2–3 applications at once. My apps crash or open very slowly, and even with just 3–4 browser tabs open, the entire browser crashes. Sometimes my desktop/explorer even restarts on its own.

After opening just one or two applications, my RAM usage spikes to over 95%. This wasn't the case just a few days ago; my laptop was running smoothly, and I was able to multitask with 5–6 applications and do some light gaming. Now, my games crash immediately or won’t launch at all, and Steam won't even open.

Specs:

• RAM: 8 GB
• Storage: 512 GB NVMe SSD
• Windows 11 home
• OS Build: 26200.8039

Even with these specs, it feels like I’m using 4 GB of RAM and an old HDD. It is incredibly slow and laggy. Around the time these issues started, I did the following:

1. Downloaded Ollama and two lightweight models (I have since deleted both).
2. Changed the paging file to 16 GB – 24 GB to help the models run better (I have since reverted this to default).
3. Downloaded Wireshark (also deleted since).
4. Updated Windows 2–3 times as updates rolled out.

I have reverted almost everything except for the Windows updates, but the system is still barely functional. I don't know exactly what is causing this or how to fix it. If anyone has advice on what to check next, I would be very grateful for the help!

It sounds like your laptop is hitting a major bottleneck, which is incredibly frustrating when it was working fine just a few days ago. 8 GB of RAM can be tight, but it definitely shouldn't be crashing with just three browser tabs.

Here is a revised version of your post. I’ve rearranged it for better flow, improved the clarity of the technical details, and kept your original voice intact.
