Question about Office Equipment & Supplies
The first thing to do is always unplugging computer power cord for ten minutes. This will reset the computer and can fix minor problems on any of the circumstances listed. If the computer is a laptop, also remove battery while power is not connected, so to drain power completely.
I am listing below all possibilities, followed by brief description of fix needed.
If the computer is completely off, and no light or sound is coming from the computer when you try turning it on, then you may have a blown power supply unit.
- Have PSU tested and replaced.
If when you push start button, the computer turns on, you hear the fans coming and see lights, but there is no display at all, then you may have a problem with an hardware component, commonly motherboard or video adapter.
- Start main board with minimal set of devices. Have hardware tested and repaired.
If you can see the initial boot up display, and then you get Operative System not found or No Hard Drive, then either the disk is damaged, or Windows installation is corrupted.
- Install hard disk on different computer or enclosure to recover files. Try reinstalling Windows. Replace hard drive.
If Windows start but then freezes , then windows files needed for startup had been damaged (eg. Startup.ini).
- Start in safe mode by pressing F8 on startup, if the PC is starting, then do a system restore to a date when computer was starting.
Attempt system recovery using windows install disk.
If you want more detail on any of the operations listed above, just let me know.
Do not forget to leave feedback.
