Hi , Installed a viper chip this morning but having couple of problems.

PC doent see viper chip , have checked all solder points and seem fine.

With viper in cube get black screen no laser movement but when removed cube fires up as it should. Have tried turning switches on programmer and cube is fine when viper is not on but black screen when on..

Have tried programming viper in diff computers with win98se installed but samething.

Is this install problem or is chip faulty?

Any help would be great

Cheers in advance
