My sony vaioxp laptopwont start or show me nothing on screen was working just stoped help me get it started my model no. ispcg-7a21

Replace the blower resistor...It is close to the blower.

Have you tried a different HDMI cable?

my truck has a 4.9 engine 90 model f150 pickup it just stoped fuel pump is working and got fire it will turn over but wont start why

If it's an old model, say more than 5 years, it's probably just wear 'n tear. Products stop working all the time because they are mass produced, there is a lot of room for error, especially for anything electronic. My best advice would be to call Sony and see if they will cover it under warranty.

it shows that the keyboard has been disconnected from the main board by loosing or the keyboard may gone bad need replacement, claim the warranty if exist.

Check regulator...this powers all running light tail lights etc.

one of the files in the system32 directory in the windows folder is corrupt, the files in the system32 folder contains vital files for the boot procedure, try to start the machine in "safe mode" by pressing F8 after the sony boot screen, if it allows you into the operating system you will need to choose "system Restore" take the time back to at least a week before your problems started DO NOT CREATE A RESTORE POINT
