My monitor is messing up

["Ryan Moe" <moe_ryan@hotmail.com>]

When I had my old computer the monitor started flashing yellow and colors started turning to black.  I was programming in C++ w/ Borland C++ 4.52 using Mode 13H.  I thought my monitor was messing up because it was old. Well I got a new computer and started programming again in Borland C++ 4.52 in Mode 13H and now my monitor is screwing up again.  I'm guessing that's what is doing it. Here is the code I use to set mode 13H.

 

asm {

        mov ax,0x013

        int 0x010

}

 

 

If anybody has any idea please help me.  I also use a bunch of assembly language graphics routines.  I guess those could be it but I'm don't think so.
