I bought this HP Touch Smart 310PC a year ago, the power is on and the screen is black nothing comes up.


You may have a disconnected GPU. The GPU is likely soldered to the motherboard and due to the thermal stress of heating and cooling, the contacts break. This is a major problem with HP. If this is the case you will need to have your GPU reflowed/reballed at the motherboard level.

If it's under warranty this will definitely be covered. Otherwise check eBay for "Touchsmart Motherboard Repair". It should cost between $50 and $100 for a repair.

My Touch sreen IQ 770 PC completely black out ... Windows not showing .How I solve the problem ? Thks


You need to determin if the display is defective or the video card.
Connect a know working display to your PC and if you are able to view the display, your video card is fine and the display must be defective.
Try connecting the display to another PC and see if it works, if not your display is defective.
I hope this helps.
Good luck and have a great day.
