Windows Memory Diagnostic - Memory Problem and How to Contact Computer Manufacture

[SuzqTx]

I have had the blue screen of death about 10 times within the last month with different messages.   I have used the HP Support Assistance but it keeps telling me that everything is fine.  I ran a Windows Memory Diagnostic and it said that my computer has memory issues and that to fix it, I need to contact the computer manufacturer.  Can you help?

The "memory issue" means one or both of two issues:  First, a memory stick could be failing and that would need to be replaced.  Second, the built-in memory controller chip on the system board could be failing and that can NOT be replaced.

So, you would need to buy a new memory stick and have someone with technical knowledge about opening a laptop and replacing the memory do that for you -- unless you are experienced in doing this yourself.

Where would be a good place to buy that memory stick and which one would I purchase?  Thank you for your response!!
