Vertical lines on monitor: Motherboard or Graphics card?

Trying to pinpoint on whether it's motherboard or graphics card that's giving me problems. The attached pictures tell most of the story I believe...

Additionally, it happens right after I received a couple of BSOD about memory dump (first experienced when playing Virtua Tennis '09... EA games >.>). I'm using a Geforce 8800 GTS. So far, tested on another monitor and it gives the exact same thing, as in the lines are identical no matter which monitor I'm using, and does not appear randomly. No additional graphics card to test. PC successfully booted up in safe mode but not normal mode. Basic windows repairing doesn't work.

Advise needed urgently. Thanks. Hopefully solution doesn't require me to change the whole motherboard -.-

My wild guess would be the graphic card issue. I had similar problem with vertical lines appearing on old Xfree86 after certain time, and the cause was insufficiently cooled graphic card.

It looks typical of bad VRAM - if so your graphic card is probably beyond fixing :(
Do you have an integrated video card? Otherwise the only real test is to buy or borrow another graphics card.
I wouldn't suspect your motherboard at this point though.

if possible, test the card on another PC
also; check if the fan is running, and monitor the temperature !

Graphics card is on the way out, try borrowing one off a friend if you can, plug that in and test before you buy a new card but i have had this before and getting a new card solved it straight away.
sorry bout the bad news

Check your video card for capacitor that have an FZ in the numbers please.
If you have those then that is at least part of your problem.
Basically those caps are junk. If you have them I'll explain it in detail.

If graphics card is the culprit it'll be a good news... Motherboard is the bad news. Anyway, I also think something is wrong with the graphics card, so I'm getting a new gf260 today. Wish me luck!~

Thanks for the participation. Like we all suspected, it's something wrong with the graphics card. Although if you have methods to pinpoint where the problem actually lies, comment plz. My spoilt graphics card can be the guinea pig.
