How Do I Fix a RAM Memory Leak on My PC?

Another possibility is that the issue stems from drivers or background services that aren't playing nice after the hardware upgrade. You might want to check the Task Manager. Sort the processes by memory usage to identify what’s consuming all your RAM. Sometimes, services like Windows Search can cause problems after significant changes to your system.

You should definitely look into what's actually leaking memory. Open Task Manager, go to the Performance tab, click on Memory, and check the Non-paged pool. If it's over 1 GB while idle, it's likely a driver. Tools like PoolMon can help you pinpoint which driver is causing the leak by sorting issues by their 4-letter tags. Also, make sure to check for common culprits like your network drivers or any RGB and hardware control software because those can often cause instability too.

Reinstalling Windows could be a good start. It doesn't have to be a full format; there's an option to just reinstall Windows while keeping your files intact. That said, be aware it may not solve the issue if the leak is caused by a rogue driver or application. I'd recommend trying that first.
