The tag in front of the machine says Model 6087-CE1.

Although I cannot find model 6087-CE1 in the list from the link above, the one that has the specs closest to mine is ThinkCentre® M57e Small (6305): M57e 6305-B1U 2×3 Pentium E2200 2.20 1MB Dual 1GB (I upgraded to 2GB RAM) 160GB2 DVD GMA
I have tried 3 Batocera versions: V33 & V31 (I had downloaded it some time ago) and I also tried 64bit PC with Nvidia legacy drivers (pre-GTX 750 Ti) (https://mirrors.o2switch.fr/batocera/x86_64/nvidia-legacy/33/batocera-x86_64-33-20220210.img.gz)
They all give the same results: it boots, I see the start Batocera image, then it moves to the image with date below and music plays, then it flips to the initial start Batocera image and immediately goes blank and mute.
I installed v33 on a Lenovo ThinkCentre M58p Eco Ultra Small and it works perfectly.
The problem is on the Lenovo ThinkCentre M57e Small (Model 6087-CE1). I have 2 of them and both machines give the same problem.
The Batocera v33 I flashed in the HD has a different theme than the v33 I have on the USB (I tried changing the theme just in case). Same result booting from HD or USB.
Should I try an ever older version? Could you tell me where to find it?
