Have I Smoked My Motherboard? - SOLVED

After making great progress with my servo tuning, and getting some actual movement, I put in the cheap Chinese PCI-E parallel card I had just received, and on next boot, and all subsequent, I now get these wavy lines all over the screen:

I've removed the card, I've tried the gfx card in another slot, to no change at all.
I've yet to try the onboard VGA (no VGA on screen I have), or another gfx card, or to try a RIP version - unfortunately, I got called away for work immediately after.

Just wondering if anyone knows what this is, as I have no idea!

seams to me as the Graphic card slots have alot of dirt

try without power for 10minutes to get the slots cleend by a Non oild airblow max 0,5PSI

Low wind

Figured it out - the graphics card had gone faulty.

Stole the SFF one out of the kids computer, and I'm back in business!

Glad you got it and thanks for reporting back, someone else might need it.

Definitely - it certainly enhances the forum when an issue has a known solution for others to find.
pl7i92 was onto it when he suggested the gfx card connection was dirty.
Other symptons were the computer would lock-up/freeze intermittently.
