I was able to put together my PC build and installed windows 7 on a 125GB SSD. A couple days later I added a 1TB HDD and connected 2 led monitors via DVI cables. My computer now does not show anything on the screen, even after removing the 1TB hard drive and only connecting 1 monitor with a regular VGA cable. I re-installed all components except the CPU without any success. Also reset the motherboard by taking out the battery.

Any guidance on what is wrong? video card ?

Computer Specs:
CPU = Intel Core i5-4670 3.4-3.8GHz Turbo Quad-Core 84W
Motherboard = ASRock B85M Pro4 B85 4xSATA6Gb/s 4xUSB3.0
RAM= G.Skill 8GB (2 x 4GB) DDR3 1600MHz CAS 9 1.5v
Video Card= MSI Radeon R9 270X 2GB OverClocked Dual fan
Storage= Samsung 840 EVO 2.5″ 120GB SATA III SSD
Seagate ST1000DM003 1 TB SATA III
Power Supply= SilverStone Strider Plus ST50F-P 500W 80 PLUS BRONZE Modular
Cooling= Cooler Master Hyper 212 EVO 120mm CPU Cooler

I am nowhere near an expert, just to make that clear. Before you added the 1TB HDD and attached the monitors, what monitor were you using? Did it work then? I am assuming that when you added the extra components you didn't fry the system with an electrostatic discharge, you grounded yourself first. If the computer worked before, it outputted to a monitor, and it does not now, then presumably the previous components were all compatible. I suppose its always possible that you have too much on a single socket from the wall and components either aren't turning on or are downclocking and bottlenecking. Did you check to make sure that the new internal HDD doesn't push your PSU over its limits? The only thing I can think of would be a...

Did you check to make sure that the new internal HDD doesn't push your PSU over its limits? The only thing I can think of would be a situation which I am not even sure exists anymore, and it had to do with adding in extra internal hard drives and not setting the right ones to master and slave depending on which should boot first and had the OS on it. When you say it doesn't show anything on the screen, do you mean that the machine turns on but nothing comes on the monitor, or absolutely nothing comes on? When you open up the cover on the machine, which lights are coming on and which are not? Have you checked all the connections internally? If the whole thing just isn't starting at all then I'd say that points towards a motherboard problem, otherwise if everything else is working properly and it just isn't outputting then you're pretty much stuck between the GPU, the cables and the monitor isolating the problem there.

- The monitor's "Power ON" light blinks. the screen is black.
- I had a samsung 24 inch connected to my mother board with a vga cable. then I installed a second one and I connected both to my graphics card with DVI cables. I verified that both monitors are working well as I checked both on my laptop.
- Even after disconnecting the new 1TB internal Hard drive the problem does not go away.
- I grounded myself every 10 seconds... :)
