Hello, hope someone could possible help me.
I have recently upgraded my PC with a new:
-Motherboard
-CPU
-GPU
-RAM
Since this I haven't had any signal to my monitor. I have made sure all the cables are in the correct places and I have tried my other graphics card to see if it was the graphics card(still no joy). The motherboard lights all light up and the HDD drives and all the fans work. The only thing I can think of is I haven't installed my motherboard drivers with the CD you get provided with the motherboard. I haven't done this because:
1- My CD Drive doesn't work
2- I can't get signal to my monitor to select options on the installation.
If anyone could help me it would be much appreciated.
Thanks
Cory

Following and 's direction to strip the system down, here is a concise, ordered checklist and a few often-missed checks to isolate a power-on-but-no-video situation. The steps move from quick visual checks to deeper diagnostics so responders can narrow the fault without repeating obvious items already discussed.

  • Minimal bench setup: motherboard placed on a nonconductive surface with PSU, CPU + cooler, one RAM stick (primary slot), and GPU only if needed for video. Start the board using the power pins or an onboard switch.
  • Confirm all power connectors: 24-pin ATX and the 4/8-pin CPU (EPS) must be fully seated; verify PCIe 6/8-pin plugs on the GPU.
  • RAM: try a single stick in the manufacturer’s primary DIMM and test each stick/slot one at a time.
  • POST indicators: connect a PC speaker or watch motherboard debug LEDs/2-digit codes; note any pattern.
  • CMOS clear: remove power, pull the coin cell for several minutes or use the clear jumper, then try a cold start.
  • Inspect the CPU area for bent pins (LGA) or socket damage and confirm the CPU is oriented and seated correctly.
  • Check for shorts: confirm standoffs match the PCB holes, no extra standoffs/screws under the board, and the I/O shield isn’t pushing on components.
  • PSU health: swap with a known-good PSU or use a PSU tester — some PSUs spin fans yet fail under initialization load.
  • BIOS compatibility: identify the exact board model (printed on the PCB) and compare the CPU support list on the vendor site. If the BIOS does not support the CPU, use the board’s USB BIOS-Flashback procedure or a supported CPU to update per the manual.
  • Swap-tested parts: if available, try a different known-good GPU or RAM to rule out faulty components.

Helpful data for responders to record: exact motherboard model, observed motherboard LED or beep codes, CPU model, PSU make/model, which power cables are connected, and whether the board has a USB BIOS-Flashback feature.

  1. No CD is needed for this sort of trouble.
  2. Tell more. Does the BIOS screen show up?

Here's a COMMON GAFFE. When folk install a motherboard they often short out the board by leaving mounting posts where they should be none. That and a jumper in the wrong spot. Check your work.

All of the mounting posts and the jumper is in the corrdcy place. Also before the upgrade my CD drive still didn't work but yet my computer and the monitor worked together.
Also nothing loads up my monitor just said "No Input" as soon as my computer gets booted. I have also tried a different monitor and HDMI lead, still did nothing.
I have tried using the graphics card HDMI port and the on board HDMI port still no joy

Then its time to reduce the parts till it works. We don't need a case, CD drive or HDD/SSD and what else can we go without?
Aim for a BIOS screen.
