running sensationally

My PC Bj. 2004 was very, very slow, with many crashes. I had 512 MB of DDR RAM. As PC layman, I did not know how easy, however, the upgrade of an old PC's. First, the program EVEREST Home Edition downloaded (for free). The shows which components are installed in the PC. Matching memory (should be the same model) and get fitted at Amazon sought-two days later. All ports on the PC. Unscrew the housing cover module plug-cover and connections Refit-ready. Time 10 min. The computer recognizes the new memory automatically.
Then finally change the setting of the virtual memory. In My Computer, right-click Start-Settings- Advanced-Systenleistung Visual Effects ...- Settings-Advanced-Virtual Memory Change. If is set then select "System managed size", you need nothing else to do.
Now have together 1536MB and a PC that has never been so fast. Much better than it was then re-sensational as now runs everything and that for very little money.
