As that it worked the first time, but has had problems since, can you run memtest86 for a couple hours? Maybe you've got bad memory and by chance it didn't show up the first time, but since then you've hit a bad spot.
The memtest86 is already on one (probably all) of the disks that you burned and after a couple hours would tell you if that's the problem- worth a shot, right?
YESSSSSSSS!!!!!!!!!!!!!!!!! I got a working LinuxMCE. Thank you jimmejames for pointing me in the right direction (and of course all that helped!!). When i first started my pc on wich i wanted to install mce i got a message about my memory. I just didnt pay any attention to it! i just figured it was because i just put some new hardware together for the pc to work for mce. After saving the bios the message (of course) dissapeard.
now i removed 512MB of the dual channel memory banks, reinstalled and and the lovely lady is speaking to me again
So after al the problem was indeed between chair and keyboard ... it almost always is isnt it. Again, many thanks for the support, i will keep watching (and probably use) this forum and help whenever i can!!
NB: is 512MB enough for a mediacenter with 2 MD's and a bit later a couple of z-wave modules or do you recomend 1024 or more??
