1 MacBook starting to a white screen, and then a black screen w/o chime
I’m getting a white screen on start. Every subsequent power-on starts to a black screen. If I cut the power completely, which means taking the battery out or just waiting for it to die a crap ton, the Mac chimes and starts to the white screen again. Note: I can only do things like bring up the boot picker and use internet recovery when it’s in the white screen state. Internet recovery cannot help me as far as I can tell, as I cannot install MacOS through it because somehow even though I got to it through the INTERNET, wifi won’t turn on within it and Ethernet seems to do nothing whatsoever, so MacOS won’t install through it. I had the idea of getting a USB with the installer on it, which didn’t work because of the next problem. The boot picker and internet recovery fail to set the boot volume every time. I even tried the bless tool via terminal in internet recovery and that’s basically what it said. I’ve tried transplanting 3 different HDDs and 1 SSD from other Macs into this MacBook and they don’t modify the macs behavior. I put a disc in the SuperDrive, thinking maybe it might try doing something with that letting it get further in the boot process, but all it does is spin it and nothing else. The next time I went into internet recovery, it just spit the disc out. That same day, I tried doing it again, but now the SIL (sleep indicator light) blinks 5 or 6 times and then the SuperDrive revs and if it’s in the white screen state, the chime occurs. It didn’t blink when this stuff first started happening.
this started happening right after installing boot camp (Win7), like I had done a lot before, and I tried to reboot back into MacOS from it, and then this started happening, and a few mins later I discovered my MacOS partition wasn’t even showing up in the boot picker anymore, and yesterday I found out that it shows up in internet recovery disk utility as “disk1s2” or something similar. I reformatted that partition thinking I was gonna install MacOS back on it but the %#*@ thing won’t connect to the network or the internet so that’s not possible.
I cannot take this machine to the Apple store, and I don’t have money to take it to a third party Apple repair place, Apple is saying this is a hardware problem, but I didn’t spill, bump, or mess up anything on this system prior to this happening, it was literally laying on my bed when this started.
Please help.

I also have about 3 hours in recordings with troubleshooting things I did, and the call with Apple that I did, I’ll only put them here if that would be helpful.

@iredmc - I would start off running the grey CD diagnostics program to see if an error popped.
If you don't have access to the Grey CD you might give Apple Hardware Test (AHT) a try Apple no longer offers older tools so you'll need to get this release.
The last thing that could be getting you in trouble is the drives you are using may not work properly in this system. Can you give us a listing on the exact drives you have: make, model and size so we can research what you have.
