:rolleyes: Hello guyz I've bought a board recently with a new VGA. Below are specification:
P4800D-X
GeForce 5500

After installing it to my mobo and fix the interfacing of it. My mobo boot smoothly on bios when I've logging in at windows their is no keyboard activity neither mouse activity only is i can view is the login GUI.

I've tested my keyboard and mouse activity and their is move-lity. I've try to reblast the issue by installing it again but the process won't proceed it prompts me that their is no harddrive connected but all my plugin is all in place.

I've figure out that the PSU was locking my recent PSU was 300watts 220v/3.5A was lack so I've decided to replace it by 500watts 220v/6A much higher but the their is another problem my monitor won't display anything I mean pure black. Please somebody reply with this thread i need it badly. please some one tell me what is happening...

A compact follow-up with a practical checklist and the reasons behind each step. Builds on the direction given by and adds deeper checks that help isolate whether the PSU, cabling, motherboard, or peripherals are at fault.

  • Verify the PSU mains selector and power-cord/plug are correct for the local supply and the rear power switch is on.
  • Confirm the main motherboard connector and the separate CPU 4/8-pin +12V plug are fully seated; many swaps miss the CPU power and the board will look alive but fail under load.
  • If a discrete video card is used, make sure any 6/8-pin PCIe power leads are connected.
  • Do a minimal outside-the-case bench: CPU, cooler, one RAM stick, PSU, and video (or onboard video) only. Remove drives and extras. This often reveals shorts or component failure quickly.
  • Try another known-good monitor/cable and switch input selection on the monitor. Also test the monitor on a different PC.
  • Fit a PC speaker or watch onboard diagnostic LEDs for POST/beep codes; consult the board manual for meanings.
  • Inspect the motherboard for physical damage: blown or bulging capacitors, burn marks, bent CPU socket pins, or misplaced case standoffs that could short the board.
  • If available, swap in a known-good PSU or measure the +12V, +5V and +3.3V rails with a multimeter under light load. Do not open the PSU; if you are not comfortable with electrical measurements, get professional help.
  • Reset CMOS (battery out for a minute or use the clear jumper) and try a PS/2 keyboard if USB input seems dead (BIOS/driver issues can hide input once the OS loads).

Why this helps: a failing PSU or a shorted motherboard can let fans and LEDs run but fail to supply stable voltages under load, leading to blank screens or lost devices. Run the non-invasive checks first, document voltages/symptoms, then swap suspected parts (PSU or board) to confirm the faulty component. If physical damage is found, motherboard replacement or RMA is usually required.

Check the jumpers on the Hard drive make sure all you ribbon connectors are right, red wire to pin one.is the system coming on if so make sure you video cables are connected securely.going to a higher rated power supply won't cause one to stop working there is something as far as a cable or something that simple not right.

My board got busted that's was the initial assumption, I'll try to connect all my hard drive to other mobo then all of them except the motherboard. So i brought my board to the shop for my warranty and they tested and the result is a blackOut board so they replace it, Now it's work smoothly.
