I just put my computer together with all the components. My mob is a GA-P35-DS3L/S3L(Gigabyte). My other components are Corsair 450W PS, 2 DDR's 1gb each(Kingston),Seagate HD. I also installed a e-GeForce 8500GT Graphics Card. My CPU is an Intel Dual Core & my fan for the CPU is a Arctic Cooling Freezer 7 Pro for Intel Socket 775. I'm using an older monitor for now till I can afford an a new screen. When I turned the computer on for the first time, it started up then cut out & restarted. Nothing came up on the monitor,but noticed the monitor light was flashing green. I doubled checked my connections & they were good. I tried it a couple of times, but same results, it would start, then cutout, then restart, flashing green light on the monitor, black screen. A few things I observed during the initial start up was the the CPU fan was not turning & the fins were heating up on this fan. Everything else seemed to be OK, the other fans were working the DVD drives seemed to be working, the doors would open close. My question is, Is the CPU fan defective, & would this effect the video on the monitor. If anybody would help me out on on this issue would be much apprieciated. Thanks.
