Seeing Treble

I’ve got an AJP 350i laptop with a SIS lynx 3d graphics card. Recently after replacing a floppy drive the screen appeared to be showing three of everything. I tried all tha usual..upgrading display adapters, lowering hardware acceleration etc.. butthe problem is still occuring. What’s worse is the BIOS boot up screen is in the same state. Pentium Processor has now become pppnnntttmmmm ppprrroosssccr. I’ve checked for any loose cables on the system but there aren’t any and i’ve tested the screen of the laptop by running the laptop through a standard monitor but the display is still garbbled through that.

Any ideas or any help greatly appreciated.

Cheers
