It seems that your chipset or networking drivers needs an update, also cleaning up the log files can help. If using Windows: Some uninstall the driver and and then reinstall it driver with Windows Update.

Black/Blank Screen has always to do with video card driver (crashing and restarting), happens a lot when messing with overclock values (overclocked GPU). Sometimes a simple graphics settings adjustment helps (had this case when running Win7 64 and an Nvidia card: it is called TDR, Time-out Display Recovery: I underclocked my base and memory clocks by 50mhz and turned my voltage down by 12.5.).

Nice to see you trolling again

Since almost all games were running with Java, and this isn't supported anymore, many technical issues are on the road. Therefore older graphic cards don't work anymore or they do but cause many issues. Also some browsers don't do a good job, namely Blink-based browers (Chromium and Chromium-based browsers like Chrome, Brave, Opera, Vivaldi

). The only browser that can be fully recommended is Firefox (Gecko-based browser).
