Acer Aspire 5250-0895 getting a black screen when i turn it on, sometimes it comes on but most of the time it just turns on, no beeps just a black screen.

Although not certain, it may be caused by a connector getting flaky.
If you are adventurous, unplug the system, remove the back panel and anything you find that is plugged should be carefully removed and plugged back in again.

Some connectors have a high number of contacts which makes them prone to this kind of problem.
If you recognize the memory cards, don't forget them, they can contain up to 288 contacts and any of these going intermittent will cause this.

Pix of these modules can be seen here if you aren't sure:

You might want to start in the safe mode. Right after you reboot your computer keep pressing f8 and it should start in safe mode. Once there you could then possibly see if you can solve the problem.

Good luck,

The beeps are post during post the very first work is done by the RAM , all the memory in the RAM is first transferred to the hard disk,and remains active untill turned off.

hi there,
try to reset all ram again if not solved change the screen

I have been fixing computers that has long beeps and short ones. It is usually attributed to memory problem connection. Open the memory compartment at the back of the PC then detach the memory card. Clean with cloth softly enough not to destroy the circuit board or a pencil eraser to clean-up dust that caused the connection blockade. Reconnect after cleaning.

Sometimes the function keys get depressed by accident and it takes away your display. Press the FN+F5 and FN+F6 three times each and see if your display comes back on.

Try removing the ram , if more than one stick, one at a time. Or try reseating the Ram.

The bios beep codes indicate the video card is not working, so you won't see anything on the screen.

Your video card is either dead, or is not contacting the board correctly.
If you are keen to open it up I will offer instructions to assist you. But in reality, your safest bet is to take it to a laptop shop and get them to do it. There are a lot of tiny screws in these things.
