Dell Inspiron 17R-5720 Again! Panel goes to snow (hash?) or lines. Picture below (if I did this right) Bad panel or HDD?
Very intermittent,this happened almost a year ago too.
This is my PC. The last time I took it to a local PC shop where they let it run and "tested stuff" but found nothing wrong. It has been working good until a few days ago when it started again. It froze up with garbage covering the whole panel. Usually it looks black & white but sometimes it has colored horizontal streaks like this picture. I have to hold the power down to turn it off, then everything is normal again.
I did Dells diagnostics "Pre-boot System Assessment" that checks all the hardware and the system.... no problem found! It doesn't seem to be sensitive to moving, tapping, twisting, etc., but I haven't opened it up to check connections... yet!

I can't see the pictures,but snow or lines on a laptop usually means one of the two things:

1.Bad panel
2.Bad iGPU

No picture attached.
Hard drives don't cause picture issues. Memory, GPU, panel or cable are usually the cause.
Download and burn this CD http://www.hirensbootcd.org/download/
Boot the CD and run Memtest, this will rule out the memory.
