Windows 7: PC significantly slower after removing bad RAM (8GB -> 6GB)

PC significantly slower after removing bad RAM (8GB -> 6GB)

Hey

I recently decided to completely clean up my PC because the CPU and GPU temperatures were a bit high. So I cleaned fans, graphics card, changed CPU thermal paste etc.. Then after reassembling everything back together my PC would boot but it wasn't showing anything, just a blank screen. So after a lot of testing of checking whether everything was put in the correct place, i found out that one of my RAM sticks was causing the problem. I removed it and then my PC was booting just fine. (Btw in the process of testing I removed the CMOS battery and my BIOS settings were reset, so I had to change the RAM voltages again)

After all that my PC is really slow right now. Even for simple tasks like opening a browser or watching an HD movie on VLC, it lags a lot. I tried lots of different things to get it fixed. I'm 99% sure that my BIOS settings are exactly the same as they were before.

So I would appreciate if I could get any help from you guys! I attached some screenshots as well!

Thank you!

You have three stick of ram install. You have a dual channel motherboard.
Two or four sticks of ram will run in dual channel.
One or three sticks of ram will run in single channel.
Single channel is slower than dual channel.

Could you post a screen shot of this?

The Problem Might Be Cause Because Of Recent Change Who Have Made By Removing Your RAM.
Your Operating System Is Compatible With 8 GB RAM Not 6 GB RAM.


1.Try To Reset Your BIOS Setting To Default.

2.If It Doesn't Work Then Try To Remove Unwanted Junk File(Use Advance System Care Or C CLEANER) And Defragment Your Hard Disk.

3. If This Also Doesn't Work Install New Operating System By Formating Existing One,Remember To Take Your BackUp Of Important Document And Files.



Your Problem Might Be Because Of Incompatibility Between Hardware And Operating System.

Absolutely don't need to go to those ex streams.
Windows 7/64 is fully capable of using 6 or 8 gigs of ram.
The OP has already set the CMOS to default.
Advance System Care is nothing but snake oil.
Their is no reason to do a format and install to solve this problem.
-------------------------
vpro please don't install Advance System Care by IObit.
You will most likely end up doing a Clean Install.
It cause more problems than it will ever solve.

I never thought that three sticks of RAM would make it run in single mode. That could actually be the problem. In the meantime, I attached the screenshot you asked.

Thanks!

Try using just 4GB, in the recommended slots for 2 RAM sticks. I suspect, as Layback Bear, you have one stick in single channel mode which will slow you down.
All of your hardware should be fine, no reinstall needed.

A re-re-check of all connections could be in order, I've repeated the same mistake before, a few times.

From Resmon, you have a lot going on, Chrome is a big hog of resources.

I formatted my PC two months ago and it was running just fine until i removed the 1 stick of ram. So that's definitely a hardware issue rather than software.

Thanks for the advice guys I'm gonna test 4GB in a bit and will let you know!

You may be able to get a warranty replacement for the bad RAM, most have a lifetime warranty. Replace 2 at once to get matched ones back.

I removed the other stick of RAM that was sitting on the dual mode. Now only slots #3 and #4 are being used. But unfortunately the PC is still slow. No way near the performance I was getting before i removed the bad RAM. I'm guessing a problem with the motherboard or BIOS settings are messed up.

@Britton30 I can't get a warranty because the store I purchased the PC has closed 2 years ago

Any other ideas guys?

Thanks

Did you install something new? Your Standby RAM use is high too I think, even though it's available to use.

Who ever made the RAM is responsible for claims.
