A Correct answer
Explanation

Junk or grainy display with irregular lines is typically caused by faulty or loose RAM. The RAM sends video data to the display; when corrupted, it produces distorted visual output. Hard disk, processor, or operating system issues would cause different symptoms like boot failures or system crashes, not display corruption.
