Looping Flower Screen

I have scoured the forums and cannot find a definitive answer to my issue… I have the flower splash that keeps looping. I followed all standard instructions. I am attempting to re purpose an old desktop, the Dell Dimension 4600C.

I did the install via a USB. The install finished and I removed the USB before reboot. The looping flower logo then continues to cycle.

Can this system simply not handle it?

Any and all advice and comments are welcome…Thanks…

Anyone? ive read that maybe 4600c integrated video graphics might not be real compatable?
