I just finished my new machine and everytime it has been off for a while and i power it on it goes past the bios screen windows starts to load then screen goes to no video signal at which point i hit the restart button and it boots fine and all is well. i think its the psu its an old crappy corsair cx 500 that i bought used and this is the second computer of mine that ive used it in. What do you guys think? My PC:
AMD FX 6350
G-SKILL ripjaws 8gb
ASUS M5A99X MOBO
Gigabyte GTX 750ti 2gb
Windows 8.1
Corsair cx 500
