8400 Problem!

[Ratul]

Hi, I have two problems with my Nvidia GeForce 8400 GS, brought 2 months ago.

1: When I start the computer, it starts but I can't see anything on the screen, if I restart it, then it shows up.
2: When working, the screen goes black and then it comes back. Like, I am typing, and the screen goes black and then it comes back again.

What shall I do?
Quick help is appreciated.
Thanks, Ratul

Update drivers, check Bio's to see if onboard is not checked..

Power supply? Brand and model?

What were you using before you got the 8400GS?

The 8400 GS got finally destroyed and my computer mechanic instead gave me a GeForce 210.
