Hello,
Embarrassingly enough, this is my first time trying to build a PC. I'm a software developer so have never really had to worry about hardware before and figured this might be fun. I apologize if I misuse any terms, because I learned them all in the past few days.
I purchased all my parts (everything) from a local store. The salesman installed the CPU and CPU fan for me when he gave me the motherboard (an ASUS P8Z77-V - image at http://i.pcworld.fr/1228499-p8z77vdlx-haut.jpg ).
It took quite a while and I watched a lot of videos but was able to get it up and running. I installed Windows 7 64-bit, got my video card working with some test games, and was 2 hours in to transferring music/apps over when I was installing a mouse driver (for a Cyborg R.A.T 7 mouse) when my mouse and keyboard stopped responding. I figured it may have to do with the installation of those USB mouse drivers and waited patiently for a few minutes. 10 minutes later and I knew something was up. I restarted my PC. It then never started again. I opened it up and found that it would just infinitely loop between the CPU_LED and DRAM_LED lights, back and forth.
I have tried resetting CMOS, leaving it over night un-powered, tried setting both ram sticks in and out in different configurations, and unplugging everything but the power. There's a giant CPU cooler on it ("Cooler Master"). To see if the case or cooler was causing a short, I removed the motherboard from the case, removed the CPU cooler and everything BUT the power, and powered everything on - still I get the flashing lights back and forth. I didn't try this too long after removing the cooler because I don't know a lot about these things and didn't want to risk it overheating after 10 seconds. The fans and everything work fine if they're plugged in, so I don't think it's the PSU (a Corsair HX650W).
Because of everything I've removed, this problem is somehow being caused by:
-The motherboard itself
-The CPU
-The 4 and 24 pin power adapters
I would think everything points to faulty hardware - but the problem is that everything worked fine for a few hours, and powering down and then up again (which I had done many times before) caused something to stop working. This happened as I was installing a mouse driver/software. Could this have any effect on the hardware or is this just a coincidence?
I recorded what the lights look like when I try to boot: http://youtu.be/w_qEBh2HfU0 (note: this before I removed it from the case and stripped everything but the power cables - but nothing has changed since then. Imagine this happening sitting on a table with just two power cables and a single stick of RAM plugged in).
If anyone has any suggestions I would love to hear them - this is my first time dealing with the inside of a PC and it's driving me insane. I had lots of problems before this and coworkers provided me with suggestions that got me up and running. I'm on my xmas break so I don't have those resources anymore though.
Any help appreciated
Thanks!
EDIT: If anyone has similar symptoms... check that your case's "reset" button is stuck in the down position. Obviously this just causes the first few startup checks to loop infinitely.....
