I recently built a computer. Here is the hardware I am using.
CPU- Intel Core i5-660 Clarkdale 3.33GHz 4MB L3 Cache LGA 1156 73W Dual-Core Desktop Processor
Power Supply- Rosewill Xtreme Series RX750-D-B 750W Continuous @40°C ,80 PLUS Certified, ATX12V v2.2 & EPS12V v2.91
Hard Disk Drive- Seagate Barracuda 7200.11 ST31500341AS 1.5TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive
Motherboard- GIGABYTE GA-H57M-USB3 LGA 1156 Intel H57 HDMI USB 3.0 Micro ATX Intel Motherboard
RAM- G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBRL
I finished up following the motherboard instructions to put it together and had everything hooked up according to it. I put on my operating system (Windows Vista Home Premium) and it installed completely. The next day, I let the updates for just Vista install (I was going to install Microsoft Office and Mcafee afterwards). The final update was finished so I shut down the computer, unplugged it and let it discharge. I then connected my old hard drive (there was music and a bunch of files I needed off of it),closed the case, plugged it back in, and pressed the power button. The computer started for about a second or two then shut off. All my chassis fans and CPU fan turn on and it sounds like my hard drive is becoming active. I have been taking the computer apart and testing each thing individually and can't pin point the problem.
Can anyone help?
