hi

The Diagnostic LED blinks red 6 times and the system beeps 6 times (once per second), then a 2-second pause follows:

This indicates a pre-video graphic card error.

To resolve the issue, complete the following steps:

1) Reseat the graphics card.

2) Replace the graphic card.

3) Replace the system board.

" this happened after i change some settings on the BIOS PCIe to (Compute)"

try to reset the bios to default first
