I bought the ASUS GeForce GTX 750 Ti 2GB a couple of weeks ago to go with a new system I put together and I get errors on occasion when I boot or reboot and I'm just wondering if I should exchange it for another one (of the same, I like the card) or if post beep errors are kinda not a big deal... I mean I can get it to boot but it sometimes does it more than one time in a row. May be a defective card. Thoughts?
