I am working at a Non-Profit. I recently upgraded the components for a DELL Dimension E521. The RAM on that thing seems to be not working after MemTest and I replaced it with a 2GB Kingston DDR2 667Mhz PC5300 RAM which is compatible according to Crucial.com. I added a new hard drive 500 GB in because the old one just had 40GB.
I did a Windows 7 Pro 32bit installation and for the first day it worked proper and from then it started to give me constant blue screen every 3 hours.
Do you guys have any suggestions on how to fix this issue?
