cpu is an amd phenom x4 9600

Hello everyone, I am having troubles with an old computer that i received from a friend a few months ago. It's a rather old pc, but I still would like to get use out of it. :) Thinking about converting it into a htpc perhaps.
Anyways, the problem lies that when I turn it on, it's just stuck at a black screen. I have pulled the cmos battery out, waited a few seconds, reset the cmos to default by moving the jumper between the pins, both nothing. tested with various power supplies including a new one that i just bought for my wife's future build. regardless of psu, nothing.
Most recent attempt to fix- Removed all components except psu, cpu, and motherboard. When starting up, gives one long beep followed by two short beeps. After some digging around google, found that for asus boards, that this means that no ram was detected.
Also, for longest time, I didn't realize that the board given to me didn't have a speaker to listen for POST beeps. So, for longest time thought the board was completely dead. So I dug up an extra speaker that i had laying around, and that is how i got the beeps indicating no ram.

Well, now i'm back to square one. I put the ram and hdd back in the pc, fired it up. No beeps now, just silence.

wth is wrong with this pc?!
-sigh-
any help is appreciated

ok, moved ram from slots 2 and 4 to one and three. started once, no go, shut off, started again. amazingly, load up.

Now, got to windows menu, then froze, and blue screened....
 



well, after the blue screen and shutting it down, its back to square one.. turns on but just a black screen. :/
 
UPDATE- apparently hitting the reset butting nearly 500 times gets it to finally start again. now, running a windows memory diagnostic tool. not sure if that will help or not. my goal is trying to get it into safe mode, as suggested by kapitalistas.

update 2- windows memory diagnostics doesn't appear to have issues. rebooting into safe mode now.
 


well, here's what i've done... got into safe mode, did system restore to last restore point, restarted and now appears fine.
by network, do you mean with the ethernet cable plugged in? if so i've had it disconnected the entire time.

also, not sure if matters, but both times i've managed to get it back up from the black screen, i've had the pc tilted at an angle. not sure if that would help or not. -shrug-
 


when it has given me problems, it was just a black screen, not even bios post. idk whats going on with this pc, one minute seems fine, next its acting all kinds of crazy.
