Hello all! I'm attempting a new build and having some problems and was hoping I could get some help. I'm afraid I may have screwed something up, but first
here are the parts I have:
CPU: AMD Athlon X4 760K 3.8GHz Quad-Core Processor
Mobo: ASRock FM2A75M Pro4+ Micro ATX FM2+ Motherboard
GPU: XFX Radeon HD 6670 1GB Video Card
Case: Sentey CS1-1398 PLUS ATX Mid Tower Case
PS: Antec Basiq 350W ATX Power Supply
RAM: Crucial 8GB (2 x 4GB) DDR3-1600 Memory
CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler
Anyways here is what happened.
Many, many, years ago, my dad and I built a PC. (to date myself I think it was a 286 with like a 20 MB hard drive lol). I remember the project being fun and engaging, so for my son's 10 year old birthday, I decided to have a similar joint build project. After all while many details have changed, the basic components are pretty much the same.
The build proceeded smoothly until I got to the CPU. The literature was clear that no force should be applied to insert the CPU, it should simply 'fall' into place when inserted correctly. I did this and I felt like the CPU was correctly installed. I then proceeded to install the cooler. I put a dab of thermal grease on the CPU (perhaps a bit too much in retrospect.) When I first put the cooler in place, I noticed I had the bracket oriented wrong so I needed to pull the cooler off to re-position. As I did this, to my shock and dismay, the thermal grease acted as a very strong adhesive, and the CPU pulled up (with the locking arm still locked!) with surprisingly little force! Because of this, I'm not so sure I had the CPU installed correctly the first time.
After I got the CPU and cooler separated, I inspected the CPU. There were about 6 or so pins partially bent, but it otherwise seemed intact. I painstakingly straightened the pins. I re installed the CPU, but this time I applied a fairly significant amount of force to get it inserted. (Perhaps not that much force in the grand scheme of things but certainly more than I used the first time and more than the "no force" the literature calls for.) The CPU then felt solidly locked in. I re-installed the cooler, and proceeded to wire and install everything else.
Once I had everything assembled, I attempted to fire up the computer. The power button on the front of the case works, and I see the power supply kick on, hear the hard drive spin up, and the chassis and CPU fans turn on. However, critically, I don't get any video output from the graphics card. The fan on the graphics card spins up normally.
When I saw this, I figured that the most likely explanation was that I fatally damaged the CPU when I re installed it with increased force. But to my surprise, when I pulled the CPU back up, all the pins appear to be straight and undamaged.
I have since attempted an external build and get the same symptoms: CPU fan, GPU fan both spin up normally. There is no BIOS beep, no video.
So my overall question is how do I isolate the problem between the CPU and the motherboard? Or should I bite the bullet and get a new CPU and motherboard?
