So my problem is that as I was playing guild wars 2 and all of a sudden my computer flicked off. Now it didn't turn back on and still wont. My question is when looking at my specs of my pc that was prebuilt and add 2 fans a gtx 560 ti and a better heatsink fan(what i upgraded to). I dusted the pc very well and my friend who's career is fixing computers installed all the parts. It was working great but then after a few days of use it is dead i've had this rig for a little over a year now and it is still under warrantie. So I got the ball rolling with new egg and first the secondary warranty place (new egg extended warranties) told me that I replaced the GPU that I killed the psu but it was rated at 600w but probably since it is a 30$ power supply i have doubts that it produces that much. thx in advance
