Hey guys, currently having a problem with my PC not booting at all and need a little help. First, here is my setup... AMD Athlon 64 FX 62 Dual-Core CPU Asus Crosshair MB 2GB's of A-DATA mem (2x1GB) Coolermaster mini R-80 liquid cooler EVGA 8800 gtx gfx card Tagan 1100w PSU Single Hard Drive (160GB SATA-II 3.0Gb/s 8MB Cache 7200RPM HDD) 16X DVD+/-R/+/-RW CD drive X-Cruiser Mid-Tower case The setup has been working perfectly with no flaws till I cleaned it the other day like I would normally do with just canned air. The pc will not boot now. The only response I get from it is that the MB lights power on. no fans spin, no PSU fan spinning, no drives spinning. Also, if I leave the PSU on and MB lights on, the MB lights will start to flicker rapidly after so long. I did plenty of tests, pulling piece by piece and same results. I stripped it down to the MB and PSU and still get the flickering MB lights result. So i decided to test out the PSU with a paper clip and shorted the green/black wires and the PSU started fine with fans spinning. Could it be the MB? Is there any safe ways to test the other components? Also, my Asus MB has a power switch on the MB itself so i don't need the power switch connected from the case. Any ideas/help would be appreciated =). Thx.
