Hi guys, i just finished getting all my parts together to upgrade my computer with new graphics card. I got a motherboard that can support EVGA ge force gt 560 ti (not sure if im saying it right) but it required newer power supply. I went and got a new power supply and installed everything after getting my hands all bloodied out and did not do any damage to motherboard imp (discharged static and so forth). Now for my new power supply is 750W and i connected the proper pins to ram, motherboard, connected the 24 pins, and 2x 6 pins to the graphics card. plugged all fans properly and thats about it. Now when i first tried to boot the computer the screen was all black it would say: No signal detected etc etc. (no beeps). Now i finally tinkered with it and redid everything step by step and i still have black screen however this time there is large beep!!!!!!11 (im happy for i know now i did not damage mother board) but i am scared that either power supply is failing or my graphics card is not working properly. Imo it is because all fans are plugged in properly. If it was power would the computer even turn on to start with? Idk. pls help me out if you can i want to make sure i do everything before i take it in to switch to new psu or get refund for graphics card etc etc. Thanks!
