Hello! Maybe someone here can help me :)

My desktop was working perfectly This morning and then this evening I moved it literally two inches and now the monitor won't display anything. The monitor works great, but what concerns me is that the Desktop turns off rather quickly. It used To always take forEver.

I've moved over from the vga to an hdmi. I took out the graphiCs card so that it has to use the one on The motherboard but then It still didn't display anytHing. This makes me suspect that its the motherboard.

Any tips would be appreciated before I go drop it Off at some repair place. Thanks ;)

With the external checks already suggested by , the checklist below focuses on internal hardware and firmware steps that haven’t been covered yet.

Start with power and firmware: verify the 24‑pin ATX and the 4/8‑pin CPU power connectors are fully seated and inspect the board for bulging capacitors, burn marks, or loose standoffs that could short the PCB. Reset the BIOS/CMOS to defaults (power off and unplug, remove the coin cell for ~5 minutes or use the board’s CLR_CMOS jumper, press and hold the front‑panel power button once to discharge residual charge, then replace battery and power on). A CMOS clear will force the motherboard to re-detect onboard video if the BIOS was locked to a discrete card.

Do a minimal-boot for clear POST diagnostics: remove all peripherals and expansion cards, leave only CPU, one known‑good RAM stick (try each slot), onboard video, and PSU. Connect an internal speaker or watch motherboard POST/debug LEDs during power-up. If fans spin briefly and the system cuts out without POST, suspect the PSU or a short—verify with a PSU tester or a known‑good supply. If the board reports beep/LED codes, consult the motherboard manual for the exact meaning.

If CMOS reset + minimal‑boot + PSU check produce no video and no POST codes, the fault is most likely the motherboard or CPU. Inspect the CPU socket area for physical damage (bent pins on some platforms, damaged VRMs). If warranty or spare-parts swaps aren’t available, handing the machine to a repair shop is reasonable; summarizing the CMOS reset, minimal‑boot results, and any PSU checks will speed their diagnosis.

Plug the monitor into another PC if you have one to test. Try a new cable incase the current one is faulty. Triple check that the video card the port is on is actually enabled. Make sure the cable is snug in both the monitor and the video port. Try another video port if you have one. Connect the external monitor to a laptop if you don't have another desktop? Try lots of different scenarios to troubleshoot.

How many monitors are plugged in?
