Question about Computers & Internet
Posted by Anonymous on
Let us first find out what is wrong. This can be due to many reasons.
1) If the Caps lock, Scroll lock & the Num lock lights are blinking when you switch on your laptop, then, the problem is with RAM. It is either dislocated from the slot due to impact or not functioning properly.
If so, you need to open the back cover over the RAM slot while your laptop is off and unplugged. Remove the battery, pull the RAM chip(s) out and then place them back properly.
Fix the cover and the battery back and restart. Check whether it boots.
2) If it doesn't, restart it in a dark room to see that does it try at all to start. Is there any blink on the screen. If YES then insert the Windows installation disc to see whether it boots from it. If it does, so for so good. These steps may be helpful:
>>Select the region and language.
>>Just when it says install now, select Repair your Computer (for Vista & Windows 7).
>>It will scan for windows installations.
>>From the Repair menu that appears select startup repair.
If the problem still persists, it might be with the Master Boot Record.
>>Reach to the Repair menu any way.
>>Select to open a command prompt window.
>>Type C: and press enter.
Then type diskpart and press enter to open the windows disk partitioning utility.
Then type list volume and press enter to view the volumes.
Then see the volume of the system & boot partition (Generally 1).
If the boot volume is marked as active type exit and press enter.
>>Now you are at the command prompt.
>>Now, type bootrec.exe/rebuildbcd and press enter. Windows will write a new MBR on the partition.
>>Next, type bootrec.exe/fixboot and press enter. This will write a new boot sector on your hard disk.
>>Next, type bootrec.exe/fixmbr and press enter. This will fix the bootstrap loader to the new Master Boot Record.
Type exit and press enter to quit command prompt and restart your computer.
The problem must be fixed.
Let me know what happens.

Hard to tell if your screen is bad or the video driver.
So, connect an external monitor and turn the system and see if you can "see" what is going on via the external monitor. If everything works well there, then I would suspect the LCD panel needs help (could be the LCD or the inverter).
If you can boot into safe mode, boot in and change the resolution to the video driver or uninstall the video driver and then in the reboot it should try and install the default driver.
