Sparklies on both monitors

[PsiFox]

Usually suggests to me, either power supply of GFX card. Annoyingly no spares for either so which to order first?

"sparklies"? you mean pixelation/image corruption?

laptop or desktop, vga/dvi etc?

 

[PsiFox]

yup sorry image corruption on output to DVI monitors!!!

Horizontal and vertical banding.

Have you tried different cables?

Start at the cheapest item and work up

Graphics card and bad solder joints in my case.

Stripped it down, cooked it in the oven and it was back to normal working

yup as first check, especially cheap and nasty cables (i know its digital but still flimsey cables are evil) and newly introduced sources of interferrance.

Mines did this the other day after playing bf3, I thought it would be the cards as there old. I just reinstalled my drivers and worked for me. Id try that first, no harm if it doesn't work, just one item to check off the list

Had horizontal lines when playing videos and occasional loss of sync to the monitors. New graphics card sorted it, but I'd agree with others - cheapest item first....

Cables already checked.

When checked voltage rails seem fine on psu, but of course transitory events are undetectable unless it happens when you test!!!
Still need to update gfx to play BF3 so perhaps I'll just do that
