Hello everyone i need some help!

I have an Acer Aspire 5051, now when i try and turn it on, the power light comes on, fans kick in as normal but no screen just black, the hard drive light is constantly on though. It will turn on with the power button fine, but when turned on will not respond when you holding down the power button, you need to take the battery out to stop it.

I have tried resetting the bios (plugging usb stick in with data downloaded off Acer Website) like many other posts have recommended with no joy,

Any Help would be appriciated.

Regards

Mark

A short diagnostic roadmap for the Aspire 5051 issue described by . is right that this is likely a hardware problem, and ’s suggestion to check the RAM is a practical first step. Before paying for a repair, follow the sequence below to narrow the fault (each step is low-cost and reversible).

  • Power‑drain and quick checks: unplug AC, remove the battery, hold the power button 20–30 seconds, reconnect AC only and try to start. If the machine responds differently, repeat with the battery reinstalled. This simple discharge/reset often clears stuck power states. (ifixit.com)

  • Isolate display vs. board: connect an external monitor (VGA/HDMI) and power up. If the external shows an image the internal panel, inverter/backlight cable or hinge wiring is suspect; if both are blank the motherboard/graphics or BIOS is more likely. Also do the “flashlight test” (shine a bright light at an angle across the screen) to see if there’s a very faint image — that indicates the LCD is being driven but the backlight is dead. (featurelens.com)

  • Memory/HDD isolation: with power off, remove and reseat the RAM modules; try one stick at a time in each slot. Also temporarily remove the hard drive and try to power on to see if the system at least posts to BIOS/boot menu — a stuck HDD or boot loop can sometimes mask POST behavior. (featurelens.com)

  • BIOS recovery caution and method: if a BIOS update/reset was attempted, use the model-appropriate “crisis disk” procedure only (exact filenames, FAT-formatted USB and the Fn+Esc sequence are required for many older Acers). A wrong file or interrupted flash can leave the board unresponsive, so follow the official recovery steps precisely or stop and seek pro help. (manualzilla.com)

If these checks don’t produce any screen or POST activity, the likely culprits are the LCD cable/inverter, GPU power rails, or a failed motherboard — at that point a repair shop can test voltages and replace the failed part. If data is important, remove the drive first to preserve it. For CMOS/BIOS resets that require opening the case, follow the safe battery/CMOS procedures shown on Acer support discussions or get professional help. (community.acer.com)

Summary order: power‑drain → external monitor + flashlight test → reseat/test RAM → remove HDD → BIOS crisis-disk only if you have the exact files; otherwise stop and consult a technician.

I think ram could be damaged try to replace the ram, if not worked then may be ur graphic card is faulty.
