Blue vertical lines at startup - cant boot Windows

First, my specs:
ASUS K8V-X
AMD Athlon 64bit 3000+
Nvidia 4200Ti+
1 GB RAM


So I was playing HL2 last weekend and suddenly my screen gets all messed up and frozen. The only thing I could do was reboot. However I noticed that at my BIOS bootup screen there were vertical lines showing up on the logo (groups of 4-5 lines, each group about an inch or two apart). At the Windows bootup screen I see the same lines except they are blue. Right after the Windows bootup I see what looks like a BSOD show up for a split second and then my machine restarts.

I can successfully start up in Safe Mode, in which case I see the vertical lines at BIOS bootup but NOT at the Windows bootup. I initially thought was it was something to do with the display drivers, so I reverted those back to ones I knew worked before but no luck. I completely uninstalled and reinstalled with the drivers I got on my Nvidia CD, but that didn't work either.
However, while I was reinstalling my vid card with the Nvidia CD, the installer told me that one of my drivers was not up to date so it recommended updating it, which I did. When install is done I restart in Safe Mode except I see one device did not startup in my Device Manager "VIA CPU to AGP2.0/AGP3.0 Controller" (error says it couldn't get the resources it needs). I wasn't sure what to do, so I just reverted it back to its previous driver which was "PCI Standard PCI-to-PCI Bridge". This time on restart the lines were gone from the BIOS boot up screen as well as the Windows boot up and everything was back to normal.

Yesterday the same thing happened again (just internet browsing this time, no HL2).. I followed the same steps again:
- in Safe Mode: uninstall the "PCI Standard PCI-to-PCI Bridge"
- Scan for hardware changes so that Windows picked up the hardware
- Opted to install the "PCI Standard PCI-to-PCI Bridge" driver again
- Rebooted and everything was back to normal


Now I finally come to my question :) :
In one week this has happened twice, I'm worried it's an indication of hardware failure.
Does this sound like my video card or motherboard is dying? (I unfortunately don't have spare parts or another computer with which to test, so I don't have a way to rule out anything)

Thanks!

I think that you are right; your video card is dying. The blue vertical lines at the BIOS boot screen are not driver related because this is well before Windows is even loaded.
