Samsung NP-RV509-A0CIN Problem With 4 GB RAM

Hello and welcome Jeet sorry for the wait now mate read this

MEMTEST

The memtest you will need to make a bootable disk / stick andset the BIOS to boot from the optical or USBand it will take a fair time torun- some leave it overnight.
This is the current download Memtest86+ - Advanced Memory Diagnostic Tool

But one thing is very important you must let the test run for at least 8passes any less and the findings are no good. Now if errors come upstraight away then you can stop it - see my pics. Now if there are errors andyou have more than one stick of RAM in then you will need to test each stick ieremove the sticks and replace stick 1 in slot 1 and test no errors do thesame in slot 2 with stick 1 no errors then repeat the process with stick 2 -that will show up the faulty stick - the other thing is it could be a faultyslot but most unusual. With more than two sticks the process is even longer asone may realize.

It is a very lengthy and tedious process but worth it if youhave errors.

Having said that I would take out the original stick and put the new one in first on it's own as the issue has started since you put that new stick in, and if it tests out ok in slot one try it in slot 2 - tedious but you need to eliminate the slots as a problem cause..

Now while you have the sticks out I would do this



SLOT CLEANING

Now as for the slots toclean them use a strip of old credit card (or any card thin enough some arebetter than others ) about 1/2 inch wide nip the corners off one end - preferably round them offhold a piece of thin lint free cloth over theend dab on some form of alcohol - isopropyl alcohol (what we swab the skin withbefore an injection) is good and GENTLYswipe along the slots.

This can also be done for the GPU slot/s andalso the contacts of the sticks or cards - not the stick but some lint freecloth of course. See my pic for the sick but please be very gentle doing it ifyou are in any doubt - please ask before doing it but I use this all the timeand have yet to damage anything

Now correct me if I am wrong but that machine is set to boot from the hard drive and booting to Ubuntu??

If you have made the memtest bootable disk (or stick) then you must set the BIOS to boot from that source (optical - I prefer a disk - or the USB option) the BIOS then boots firstly from that source - there should be no sign of the Ubuntu booting at all - if in doubt remove the C: drive.

I did see the memtest within that shot of the Ubuntu screen but the memtest we are wanting to do is the one I linked to as it is the only one to use. You have to download the memtest program from that link and save it and then burn it to a disk or stick using a suitable program making it bootable with the Windows feature or ImGburn The Official ImgBurn Website . If you cannot use this machine then get a friend to do that as it takes only a few minutes to make that bootable disk - or stick.

You then load the disk or stick into the machine and restart the machine and it should go straight into the memtest. The test should start straight away and again it takes a long time to do some leave it overnight but you MUST run it for at least 8 PASSES unless the errors come up straight away then you can stop it because you will have found the bad stick (or slot - most unusual for it to be a slot though)

Jeet mate do not boot from the Ubuntu disk boot from the memtest disk only - it will not work any other way.

I do not know of any other memory test Windows etc etc that does this test as the one I linked. Now it does take a long time to do and you must be patient and once again unless errors come up fairly quickly you have you run the test for at least 8 passes otherwise you may as well not bother.

If you do not want to do the memtest as I have laid it out then we cannot help you.

Ok Jeet time to run some tests mate please read these do them if at all possible (in safe mode form a stick) and send back results

I know this isn't strictly a BSOD problem but am curious.


Personally too I much prefer an optical disk as I am not a fan of booting from sticks so if you can try that method if it booted then there is something wrong with the USB slots or the drivers. Same process to burn a disk mate and so cheap and I find them easier to store in a folder I keep for such stuff.

Now something else too if you have a good friend let him try and boot the memtest if it starts up then the drive you are using will be ok if not then it probably is corrupt.

But again personally I much prefer a an optical disk as I am not a fan of booting from sticks. If that method doesn't work then either the optical is faulty or we shall have to look elsewhere in the machine because it involves graphics.

Just as by the by have you updated the BIOS recently too??
