Installing a new CPU can cause a black screen due to system instability or power issues.
Hi, your motherboard is Asus B85M-E. You're running i3 4330, updated BIOS to 3602, and the new i5 4590 is working fine but the screen isn't displaying anything. After swapping back to the old CPU it functions properly. To resolve this, check if the new CPU is compatible with your motherboard model and BIOS version. Also ensure the RAM is correctly installed and the display settings are set up correctly.
Did the new CPU come in? I think it was installed. Did it function properly during our chat with the seller? Which power supply unit are we using? Please check one at a time.
It is most likely a broken cpu like what @SpookyCitrus said Contact the seller and tell them
i wasn't completely confident about this. a few years back I had a Sandybridge (second generation) Pentium G870 running on an LGA 1155 H61M board. I upgraded to an i5 3570k which was also LGA 1155, but it wouldn't power up when I turned it on while installed—no BIOS, no display, just spinning fans. Later I discovered the 3570k was an Ivy Bridge chip and required a newer motherboard, so I upgraded to a Z77 model and it worked. the key point is, if your new CPU isn't compatible with that board, it might be faulty. you could try swapping it into someone's B85M board to test, or reset CMOS/BIOS, remove RAM, storage, and GPU, then attempt a boot to see if anything appears. Good luck!
I purchased it some time back, which means I can't exchange it with the seller. Perhaps I'll pass it on to a friend who has a Haswell motherboard.
