I just bought a 2gb ram stick to add to my windows 7 PC which had already 2x2gb(4gb). The new stick is the same ddr2 800mhz although is a different brand but I read many times online that shouldn't be a problem as long as the specs are the same.
Computer started up fine, it noticed the memory had changed and I chose to continue to windows which started totally fine. After about an hour though I got a sudden blue screen of death.
I tried to restart but it got stuck on the windows logo, 3rd time computer started beeping like crazy and wouldn't even get to the logo, 4th time another blue screen then I gave up and took the new stick out.
Now everything seems fine again, but what went wrong here? Maybe I need to do something to sync the new stick to the old ones or I donno... I never had problems when I put a new stick in my laptop.
