Graphics Card Problem

I build a computer a few years ago with a AMD HD 7770 that worked fine while I had it. I later switched to a AMD HD 7870 for more power. I then decided to build a PC for another family member after they got the parts and I gave them the HD 7770. Before we assembled the computer he told me that he got a used Processor and a used stick of ram. I was kinda angry because you can never trust used PC parts. But after we assembled everything it looked like everything was working except there was no beep and the graphics card fan didn't turn on and there was no display on the monitor. We tried different PCIE slots and adapters but nothing changed.

BUILD:
Motherboard - MSI 970A-G43
Processor - AMD Phenom II X4 925 2.8Ghz Quad-Core -- USED
Graphics Card - Gigabyte AMD HD 7770
Internal Hard Drive - Western Digital Blue 500GB
Power Supply - Thermaltake TR2 TR-500 500W ATX12V
Memory - Hynix HMT351R7BFR4A-H9 4GB DDR3 1333MHz -- USED

No beep usually means something is missing. I'd say either your RAM is dead or your videocard is dead, or even your PSU is struggling to provide enough power (sometimes that happens when you leave your PSU set for 220V and plug it to a 110V power socket). Maybe even your processor is not properly connected.

Hint here is to bring your setup to some repair shop and "debug" it: Try to borrow another video card and see if it works with your RAM. If it doesn't, try your graphics card with some borrowed RAM. If it doesn't, try to borrow everything else. Just keep switching parts until you can get some video and check the BIOS.

Also, be very sure that you plugged every power cord properly. Some graphics card have extra power slots everywhere...

Well the problem is that it doesn't even start so I can't get to the BIOS and there is no display on the screen.

I took my current computer apart and started replacing stuff and found out the processor was the problem but then i put the broken processor back in but without fan for 5 seconds and then it heated up but still nothing so I'm not sure why it will heat up but not work..

Well, I'm not exactly an expert about that, but I'm pretty sure there are several CPUs that will heat up to the burn point in few seconds without heatsink/cooling. However, short-circuited components tend to heat in a matter of seconds and still not work. If that's the case, your CPU is pretty much dead. But in one way or another, I don't believe heat will be the main indicator that your CPU is flawed.

Since you found out your CPU is flawed by replacing it with a new one, you don't have many possible approaches here. First, I'd try to reset the BIOS just in case there are some overclock settings that could be messing your old CPU but not your new one. (If removing the battery stuff doesn't work, put your new CPU there and boot the computer to the BIOS screen just to allow you to reset to default values). If that doesn't solve the problem, then I believe you'll have to buy a new one. =/ Sorry!
