As Above really.
My GTX is an Inno3D brand. I bought it on release date way back before xmas.
I suspected my 4GB Geil ULL, which I hate but gives no errors. However, the bios beep on failed wake-up indicated a video error. I decided to update the gf cards bios to the latest from the same vendor, and lo and behold....
Vista sleep works a treat now
I'd never recommend updating the gf card bios unless you had a very good reason, you KNOW what you're doing, and you have a spare gf card and PCI express slot for recovery, but in this case I actually nailed the problem right on the head! Happy days!
