i have a asus laptop that has a single ram slot. with ram removed i seen the bios screen start and also got a 0XC5 Blue screen. Has anyone ever seen this before?

There are several ASUS laptops that have memory built in and a slot to add memory. I would go to their web site and look up the model number and see what it comes with. To help diagnose problems we really need to know a little more such as the OS. The 0x000000C5 stop error (bsod) indicates a problem with the device drivers. A faulty driver that's acting up or a recent driver update that is incompatible. Try boot into safe mode.
