Windows 7: Laptop wont boot Black screen no BIOS

Laptop wont boot Black screen no BIOS

My laptop is a Acer aspire 5738z running windows 7 home premium 64 bit and my problem is my laptop will not start. When I turn my laptop on it starts to run like normal: GPU fan starts, Disk drive kicks in, and the LED for the on button is working but nothing on the screen. I've tried too do alt + f10 for a restore, nothing happened. I've also tried to plug it into a monitor and my tv. Before this occurred it had been turned off during boot (don't ask why, I cannot answer that) and I preceded to take it apart(to fix the overheating issue due to acer not putting fan holes on the bottom of the laptop ((thanks Acer -.-)) and I didn't realise something was wrong with it until I reassembled it and tried to turn it on. So I'm not sure whether is corrupt BIOS, a hardware problem, or corrupt MBR (my own personal diagnosis, don't know whether it's right or not). Also I have tried turning the laptop off taking the battery out letting the motherboard discharge then pressing the power button for a minute, leaving it for a minute, putting the charger in then turning it on.

Thanks. =]

You may need to take it apart again and make sure everything is connected properly. Did you follow steps to keep yourself grounded while working inside the system?


As you add and remove hardware, follow these steps for ESD safety:
  1. Shut down and turn off your computer.
  2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
  3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
  4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.
Once these steps have been followed, it is safe to remove and replace components within your computer.

How long does the disk light blink if powering on? Does wifi signal burn after some time?
