The problem doesn't come from your console, but from your game cartridge. I had the same problem, and I've stumbled upon your question while Googling about it.

Recently, I wrote a tutorial about how to solve this problem which affects most old consoles that use game cartridges, such as the NES, the Nintendo 64 and the Genesis.

The tutorial is in French, so here's link to a translation by Google Translate:
Please ignore grammatical mistakes, as those are the result of the automatic translation. The tutorial is about NES cartridges, but it works with any gaming system that uses cartridges.

My sega cd shows the bio screen and freezes no logos or anything just the earth

It sounds like your Sega CD may have finally kicked the bucket. I would suggest taking apart and doing a real good cleaning. It might not help, but couldn't hurt.

My sega genesis freezes after i play a game for a few minutes

Well it could be that the game packs are dirty try cleaning them out with qutips and rubbing alcohol and trying cleaning out the console with compressed air cans too see if it makes a difference.

Sega megadrive 2 that wont load

Just keep fiddling with it. I kept messing with the video cable, where it plugs into the back of the console. I got the "Licensed by Sega, etc." message for a few seconds before it went black again, turned it off, pulled out the cartridge then slammed it back in. Now all of the few carts I own are working with the console.

Sega genesis isnt working...

Have you cleaned the Sega? What I mean is where the casset game goes. Push down the little flap, and there should be a little strip with contacts on the inside. Just clean it with a cotton swab and alcohol. And also, clean all your games also the same way.

Hope this helps.

Can't seem to play the games

Sounds bad
the contacts for the carts may be worn
get a credit card, cloth and head cleaning fluid.
put the cloth around the card and a few drops of liquid and push in to the slot and clean the contacts.
make sure none are bent out of place.
if cleaning won't help then you may need to open up and look at the contacts for dry joints; a blob of solder may help.
failing that you may need to look on ebay for a replacement console (you won't need the leads so it shouldn't cost more than a tenner including postage)

No idea why it's not working.

Well the RF Adaptors are not that great for the sega genny they seem to fail more times then not and if been sitting rolled up in a ball I would have to run a conclusion that the RF adaptor is pooched.

Another idea would pulling the top of the genny shell off and looking at where the RF jack is on the mainboard and looking to see if its burnt in any spots this could be the issue as well.

alot of people would still say its a cleaning issue either the game or the system needs cleaning but if you have done that already have you tryed using rubbing alcohal on a q-tip and run it along the carts contacts?

I ushally have a modified genesis laying around with A/V cables to be used instead of the RF cables that is another method you could try to if you into soldering at all or feel safe doing it. let me tell you besides fixing the controller port issue on a dreamcast the genesis AV mod is the easyest out there to do if you need or would like more info on this as well let me know and I will help you out

Also what model genny do you have model 1, 2 or 3?

dont forget to rate this solution thanks eh!
