Well, I bought some more RAM the other day and installed it as it should be.. And yeah, when I boot up the computer it doesn't "notice" the harddisk. It's retarded. I tried many things to narrow the problem down, but everything I did just prooved the harddisk had no problems. I mean, I have everything connected as I did the first time I booted up, 2 months ago, and it worked fine. Help = needed. Thanks.
