Just remove the battery for about 5 minutes and you should clear your cmos.

I would use tweezers (with pointed ends) if available, a solid wire (a bit risky but doable) same with a flat-head screwdriver that will just fit exactly on both ends of the solder points.

It doesn't need to be one minute, 5 seconds is long enough to reset CMOS to defaults.

Do you have another AGP GPU or an old PCI GPU to test? Could be your video card just died, been known to happen.

Battery out with PSU unplugged for a few mins should do the same as shorting the NVRAM jumpers.

5 minutes is hugely excessive. 5 seconds usually does the job for me.

Make sure your PC is unplugged from the wall or your PSU 0/1 switch is in the off position. When a PC is plugged in CMOS will be kept alive from standby power (hence why removing the battery would not work unless you remove this).

The only function of the jumper is to remove one of the leads from the CMOS battery, which effectively is the same thing as removing the battery.
