Garbled display

by jobseeker95479 / December 6, 2015 7:11 PM PST

I have an All-In-One PC (a Lenovo IdeaCentre B540 to be exact) for a little under three years. Last week the display suddenly has become garbled (see https://lh4.googleusercontent.com/-gkDZq1w5Mto/Vl0qvPqOOPI/AAAAAAAAAcY/ZI_aaJwkjJA/w1109-h832-no/IMG_3403.JPG), rendering it virtually unusable. However, you can see through the garbled image that the Windows login screen is up and running. My guess is either the video card or the video cable (not sure if there is one for All-in-one PC) has become defected. I tried to plug an HDMI cable from the HDMI out of the PC to my wide screen TV but no video output display at all (garbled or not). Do you think my assumption it is a video card problem is correct or not? If so, do you think fixing the video card worth the money since I bought the PC for just $800. Thanks in advance.

I think your assumption is as good as anyone else.

and to repair or not to repair, only you can decide that. Personally I know nothing about this computer so I am not going to make any assumption. Because this is a touchscreen, there might be something else that's thrown into the equation. Does the computer have separate video card or is it an intergrated apu? In other word, there are a few unknowns here. Good luck, what ever you decide.

(NT) Sorry, I meant intergrated gpu...not apu.

If so, then a short of some sort. That can be found and fixed.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
