[doolittlesy]

last week my computers power supply screwed up from a power surge and now I got it fixed and my tv says that the resolution is PC Connection "Mode Not Supported", nothing software has changed just replaced the power suppy and the resolution didn't change so I have no idea what is wrong the computer works fine on normal computers but my tv just will not detect it. I have absolutely no clue how what to do I don't want to buy a new thing I want my old setup back I just do not understand why it's not working. I tried changing it into safe mode but it still doesn't open up I can't even see the bios screen when I turn it on. the tv is a samsung and I am connecting it via an changing the computers resolution did nothing also.HDMI cable. Any idea on what to do?

·
Purchase the appropriate power supply and Unplug your computer.
·
Detach any USB-connected devices, printers, monitors, etc.
·
Open the computer case with the screwdriver. Remove the screws and set them aside.
·
Ground yourself by touching a large metal object. This will dissipate static electricity in your body which can damage electronic components.
·
Locate the power supply. It is usually near the rear of the case, where the plug enters the machine.
·
Unplug the power supply from the motherboard and peripherals. The power cables are usually multicolored and fit into the various drives and other internal devices by means of a socket at the end of the power cable. The power cable attached to the motherboard is usually secured with some type of tab that you have to press before pulling on the socket.
·
Unscrew the power supply from the case. Check the back of the case for a series of screws in the vicinity of the power plug and unscrew them. That should release the power supply.
·
Remove the power supply from the case.
·
Insert the new power supply and screw into place.
·
Plug the power supply back into the motherboard. Attach the drives and peripherals.
·
Replace the case cover and screw this back on.
·
Plug in the computer and reattach any external devices (hard drives, printers, etc) and monitors.
·
Start your computer. It should boot into the operating system as normal.
