Dell OptiPlex 990 model without a screen.
Your friend's Dell OptiPlex 990 is showing signs of a display issue. It powers on but nothing appears on the screen. They've tried using integrated graphics with VGA and DisplayPort ports, connected an older graphics card, and even used a GT 220, but nothing helped. The post code lights (1 and 3) were lit, which might indicate a video or PCIe failure. Consider checking the power supply, cables, and possibly updating drivers.
Check if the power indicator is flashing orange or staying solid blue. If it's flashing orange, it might point to a motherboard, PSU, or external component failure; otherwise, it suggests a memory problem requiring RAM replacement or repair.
I also managed to reinsert the RAM and it functioned properly! Appreciate the guidance!
Thanks for the helpful tips. I faced the same issue too. Replacing the RAM solved the problem!
