Question about HP Compaq Presario F750US
Hi my laptop has garbled video: different colored speckles around screen in a repeating patten (varies somewhat each time I resart it) also gets vertical red lines all across screen.
The red lines can vary when I press down firmly in left far corner of NB base, vicinity of F1 key
Sometimes will have normal video after restarting several attempts
Help please thanks
Connect an external monitor to the laptop, power up the monitor first and then bootup the laptop. The Windows image will automatically divert to the external monitor.
If the images is OK then the video card is OK.
From the description of the fault, it indicates that the fault could be a faulty video cable or video connector. Try reseating the video cable/connector on the motherboard.
Get back to me if you still have problems together with any error messages etc.
