BSOD every time I start up

[tacit]

Hello, I keep getting the BSOD with "Memory_management" error every time I start the computer, after logging in. This started happening after I had my computer thermal module and HDD replaced.

Would appreciate help on this, thank you!

I completed 8 passes of the Memtest86+ test and there were 8 errors. Does this mean that there's a problem with the RAM?

I tried to download Microsoft Security Essentials but the page could not be found.

Thank you for your help

Did you test each stick separately for 7 passes?

Yes it indicates that ram is faulty.

But which stick is the question.

Thats the reason I asked you to test each stick at a time
