2006 Compaq Presario SR1936X running Windows XP Media Center Edition 2005 SP3

This computer was a trashpicked curbside pickup that I found from a house that isn't too far from me, they had this sitting out for quite some time, now they have decided to throw it out, so now it is in my hands. I replaced the power supply as the original one was really bad (it blew up on me as soon as I plugged it in) and I installed some new RAM as the original 1GB stick was faulty. The original 200GB HDD has unfortunately long since been dead so I couldn't boot it up as is so I replaced it with a spare 200GB HDD that I had from an HP Pavilion a730n that I got rid of a couple of years ago and now it works. Specs: Intel Pentium 4 524 ATI Radeon Xpress 200 1GB RAM 200GB HDD Windows XP Media Center Edition 2005 SP3 (It says SP4 as I used a custom ISO)
