So my PC has 16GB of RAM. However after a few hours on the ram slowly starts to dissapear. I have tested the RAM multiple times and have not received any errors.

The problem with the dissapearing RAM dissapears if I reboot my PC, then all my RAM is back again. But after a few hours firefox tabs start to crash and I can't have any software open at all, until I reboot.

Have anyone experienced something similar?

Here's some unsolicited advice: learn how to screenshot

The old fashioned way: hit the print screen key, then open MS Paint and ctrl+v to paste your entire desktop screenshot in, then use the selection tool to crop just the part you want to show people. Don't skip this last step.

You can also use Win10's built in screenshot tool by hitting windows key + shift + s.

Also for your RAM issue, make sure your RAM is securely in place in the motherboard. You didn't mention what "testing" your RAM means but a common issue is people not properly setting the RAM in place when they upgrade or build their PC.

If it's not hardware then it might be a BIOS / driver issue and I know fuck all about fixing that.

The reason I took a screenshot with the phone is because when I print screen the screen turns black...

Testing my ram: Removed ram blocks put them back in. Ran the ramtester software for errors through USB.

Memory leak somewhere, check task manager after a while to see what's eating it up. Unfortunately it could be a lot of things so not much we can do from here. As an addendumb, you have a lot of useless shit on your pc judging from that pic. I suggest starting with that.

Oh yeah the RAM works completely fine and its all there for the first few hours. I don't believe my ram come loose after a few hours and then magically fit back in when restarting a PC.

Okay you definitely have some issues on this machine. The black screenshot issue almost always means there's a problem with the graphics card, but in your case we have a second symptom with disappearing RAM. A known issue with screenshotting is that if the graphics driver thinks there's not enough memory it will produce a black screen.

So given that you've reset the RAM sticks several times, and presumably have dusted the PC while you were in there, there's a few things that could be wrong.

Hardware: you have a bad set of sticks, or else they aren't compatible.

Software: try looking in your msconfig to see if you have a memory limit set. Do windows key + R, msconfig --> boot tab --> advanced settings --> maximum memory should be unchecked. Apply and restart if you need to uncheck it. If it's already unchecked you'll need to check some stuff in your BIOS.

I'm assuming you know how to get to your BIOS on startup, usually you have to hit a F key, it varies. Anyway you'll want to check the iGPU (internal graphics processor) to make sure it is disabled if you are using an external graphics card (note, do not disable iGPU Memory setting, have it set to Auto instead). The other thing you will need to check in BIOS is that the Memory Map Feature is enabled so windows had full access to your RAM.

There are other BIOS settings you can fiddle with. It may take a while since BIOS can vary and settings may have slightly different names.

Or a root kit. OP, download an antivirus rescue USB ISO like Kaspersky (if you trust Russkies) and scan for rootkits.
You might also try VMMap from the SysInternals suite.
Good hunting.

RAM doesn't "disappear". It doesn't get smaller when it overheats. Supporting the amount of RAM changing while the computer is running is a very complicated operation that needs extensive OS support*.

You have less memory available because something is *using it*. You can rule out the memory disappearing because that is insane.

Jesus christ. Get a PC you don't care about, pull out a memory module while it's running and see what happens.

* google "linux memory hotplug" if you want a general overview of what an OS needs to do to remove RAM without crashing horribly.

So it's problably a software issue and not a hardware issue? I tried resetting the bios to see if the default settings would fix it.

If it's a software issue formatting the PC would do the trick right?
