For the last couple months my screen has been very "wavy, littery, flickery." Thats the best way I can describe it. I was just wondering if this means my monitor is dying (it is about 5 years old) or could I have a power problem? I have a 300w power supply, I know I should have atleast 350w with my system but me and my friend thought it would'nt be a problem. I have 1xHD 2xCDROM 1xFlOPPY and 1x128mb video card.
