So I assembled my new PC last night and unfortunately am having some trouble getting it running. I flip my PSU on and my Mobo LED lights up; good. However, when I then hit the case “on” button, the fans start spinning and other Mobo LED’s light up for about a second or two and then everything quickly stops/shuts down. The blue Mobo LED is the only thing that stays lit up. I’ve double and triple-checked that all my PSU connections are solid. The PSU is brand-new; bought it last night. This is my second Mobo – first was RMA’d since it had burnt-out caps on arrival. System specs: EVGA 680I (122-CK-NF68-AR), e6600, 2gb Corsair TWIN2X2048-6400 R, XFX GF7950GT, 150G WesternDigital 10K 16M SATA, Thermaltake Toughpower 750w, NZXT|ZERO ATX, LG DVD-RW, Hanns-G 19” WSFP Any thoughts on why this might be occurring? Thanks in advance!
