Faulty memory causing PC freeze?

[yordancho]

Hi guys, apologies if this is the wrong section to post this but I am seriously confused right now.

I have a Dell inspiron 3521 laptop with a one 8GB ram stick. For several weeks now my PC has been freezing up (usually I notice this happens when it gets under high load - most commonly watching YouTube or if I have too many things running). I can tell when it's going to freeze as the sound starts tearing. Sometimes I will get a BSOD - whea_uncorrectable_error. Sometimes the PC will just stay frozen. HOWEVER when I pick up my laptop by the bottom (where the RAM and the Hard disk are) or move it slightly, then it unfreezes (usually it freezes again after a couple of seconds).

My question is: Is it possible for faulty RAM to cause this? Maybe a faulty Hard drive? I have ran a chkdisk as well as a Memtest86 and a mdsched.exe. All of them come back as though nothing is wrong. I have two RAM slots in my PC and I have tried using both, but the problem persists. Also I have tried to run my laptop without the batter to eliminate that as the culprit.

If anyone has any idea what faulty piece of hardware could be causing this, please share and I want to buy a new component. Thank you

How long did you let MemTest run ? ?

Hi thanks for the response. I let all tests complete fully then checked the windows event viewer for results.

Then you haven't ran MemTest...it runs in cycles til it's terminated by User...

And it should be ran 1 hour minimum...any errors at all = bad RAM.

Apologies I was thinking of mdsched.exe. For MemTest, yes it did run for a long time (over and hour) performing several cycles and in the end there was a message saying that no errors were found. What I don't understand is what hardware component is capable of freezing the whole system for a couple of seconds when disconnected and then resuming like nothing had happened when connected again. Is this the case with a hard drive?

Almost  all components could do that.

This page provides recommendations on what to do if your computer frequently freezes or completely halts.

The article names RAM as the first thing to check.

Yah thanks man that's what I'm thinking as well. It always seems to unfreeze when I squeeze the side where the ram is rather than hard drive. Just going to buy a new stick and worst case scenario I now have 16GB ram
