Heya

Since saturday morning (15/10/2011) this red light has been switching on, on my gcard, im not certain what it means as a google search didnt help much, since on the card itself the lights arent marked with their respective codes. I bought this card along with the rest of my system on september 2009, I havent changed anything in my pc, no modifications and such, and it was assembled by prophecy for me, also it seems I dont have any of the warranties, those werent shipped with the pc. My system crashes now randomly and the red light remains on sometimes even after i turn it off and on again. It cant be and overheating issue as I have monitered the temperatures, and they all are within normal range, I've read online that it might be a VDDC error, but im not sure how this just came about suddenly. I need advice on how to proceed.
