I have a PowerMac G4 dual 1.25G with 1.25g of ram. When I installed OSX.4 Tiger I have had nothing but problems.

1- It will "freeze" on me (little color wheel rotating and NEVER stops)

2- When I turn it on, sometimes the monitor (ViewSonic) doesn't turn on and the light (powerbutton on front) pulses

3- I'll be working with it and the screen will go blank - not black, but a little blue-ish color.

Question: Is my video card dying? Please help!
