If your laptop is still under warranty then any extra support could void it. aslso with you changing the hard drive its possible that the warranty is no longer valid.
I do however suspect a possible RAM issue with the laptop.
Let's check your memory and make sure there is no issue with it. Download memtest86
Get the file that is named Download - The one you want is "Download - Pre-compiled Bootable ISO (.zip)
. When it downloads, it will be labeled memtest86+2.11.iso.zip
Unzip the file once you download it. You should have a .iso file in the unzipped directory. It will look like a zip file in some cases but the file name will now be memtest86+2.11.iso
if you don't have a burning program that will burn .ISO files download burncdcc
NOTE...do not put a blank cd in until burncdcc opens the tray for you
1. Start BurnCDCC
2. Browse to the ISO file you want to burn on cd/dvd ....in this case its memtest86.iso
3. Select the ISO file
4. click on Start
Make sure the bios is set for the cd drive as the first boot device
Put the cd in the cd drive and then boot your computer.
Running the Diagnostic Program:
The basic diagnostic screen has five main sections of relevant information. Three at the top which are labeled, PASS %, TEST %, and TEST #. This will basically show you the total progress of the current test, the overall progress of the diagnostic test, and the test number is currently performing.
On the middle left hand side of the of the program interface there is a “Wall Time” section that will keep track of how long the diagnostic test has been running for. This just gives you an idea if you are not attending the testing process.
The main section to look for is the lower half of the screen which is usually blank. As long as the memory testing is going ok with no errors this section of the screen should remain blank. If the diagnostic program finds any serious faults in the memory you will see it display a memory dump of address’s in this section. This is similar to what is displayed on your screen when you encounter a blue screen of death.
You now have most everything you need to know about setting up and testing your memory with diagnostic programs. This guide should help you get to the source of any intermittent problems related to your memory.
Run memtest for at least 2 hours
If it starts showing any errors during that time then you will have to replace the memory
If there are no errors after 2 hours press Esc and that will end the tests
We will then try other options
However I would contact Dell if it is under warranty as you will either get a replacement laptop and hardware if needed. For example that hard drive would have been covered and replaced at no extra charge
. I actually had this same problem with a dell laptop and the RAM was replaced so i will wait for the results.
