Every 5-10 min my dreamcast freezes!

The pins on the controller connector might need to be cleaned or the cable might have short-circuited. Try using another controller to make sure it is the controller and not the system itself.

Clean your laser with a cleaning kit, this will help.

I noticed you said and I quote "a copy of an original game in chinese" you did say chinese right? Is it possible that the system you have may be a PAL system if so that means it's not a USA Region console meaning it won't play Region 1 USA games just PAL

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/benjamin_494963e790f97efb

Get a new console

you need to replace the hdd[hard drive]

First off, NEVER store a game console on top of a subwoofer. It is like a giant magnet, and electronic devices do not handle magnetics. I don't think i've ever heard of a VGA box, Sega brand or not, killing a console. Millions use aftermarket AV cables and adaptors on all consoles without problem. I think it likely died from being on top of the sub. Relocate it and you should be fine. Running it for a few hours isnt likely either unless you had the vents entirely blocked.
To the guest who's drive isnt spinning, I would say your drive motor has burnt out. This doesn't indicate a defect in Dreamcasts, per se, it just means bad luck or excessive dust which killed it. Either buy a different Dreamcast or see if you can find a drive replacement.
Hope this helps.

hi with your new dream cast dont put it on the sub woofer as the magnetic field it gives of can cause havoc with the chips and resistors this would be the reason why the orange light problem occured.
The vga adaptor would cause no problems.
Also the computer needs to be on flat hard surface and not boxed into a confined place or put ontop of anything else electrical like dvd plater or video as these give off heat and would cause the dreamcast to stop working over heating problems are just to expensive to repair as you might need to replace the whole board alot of people now are playnig their ps3 on carpet and then wonder why it stops working ok so remember that it needs to get air to it and not ontop of heat source.
As for leaving it on for 2 or 3 hours now they dont advise you to play it for that long but from my experiance as long as the unit is able to get air around it ie no vents blocked and not ontop of anything warm or on carpet then their should be no problems as i have played alot of my consoles for most of the day without turning off so dont worry to much about that.
Now the problem with the first console is as you probably guessed is the laser failing to read the game data this is common in all console based computers that work of cd.
But what you could do is take the laser out of the one that has the light problem and put this laser into the first console then that way it should work then you will have 2 consoles if anything goes wrong with one.
Now the one with the light problem the only parts that will be any good from the inside would be the laser things like the lid casing most of the board is now probably no good so its not worht keeping.
But if you put the laser into the first one then you could use that untill it packs up then you have the new one to fall back on so before you chuck the other two out give it a try you cant do any more damge than is already done anyway can you.
The laser will be held in buy couple of screws then their will be a wire coming from it that goes to the board the wire is just a clip in wire and should pull out of the board easily and the same putting it back in the other one.
If you need further assistance let me know ok i wish you all the best with the new one

Its been a while since i've owned a dreamcast.My suggestion wouild be to make sure the parts on the inside are clean.Game consoles are known to collect a lot of dust over a long period of time.I would wipe it down with acohol, since it drys fast and leaves no residue.Your reset button might not be getting a connection.

this the best solution it work for me

ok guys i have 4 dreamcasts the problem is people beat the crap out of em. try holding the lid partially closed with a weight on top it should read the disk and play good. the sensor that tells it there is a disk in there is probaly a little screwed up. Also get a clean cue tip and some 91% rubbing alcohol and gently clean the lens on the laser and it sould work like new. so get to the browser with the lid open all the way put a disk in and slowly close the lid at about 80 percent closed it should say reading disk put a weight on the lid to keep it where it is and try the game if it works your good. permenent solution. remove modem and the 4 screws at the bottom of the dreamcast without a disk in there pull the top off. now look at the part of the lid that hits the little black flapper (it's on the top right of the main board) now tape or glue a small amount of anthing to the part of the lid that hits the switch about 4 mm thick of paper taped to it will push the switch further in and it should recognize disks better now and all will be well in the world e-mail me for pix if you want [email protected]
