Alienware m17x R3 Bios issue

So long story short, my alienware beeps 7 times and I dont really know what to do anymore.

Long Story minus the small stuff:
Got the alienware with faulty 6990m. Updated to unlocked/modded bios *forgot which bios*. Replaced 6990m with 7970m. Everything worked fine for a bit. Alienware screen went white randomly one day. Alienware would keep booting to black screen. Took out gpu and it worked with integrated gpu so got another 7970m. Same issue, so I returned the 7970m. Now the laptop gives 7 beeps for faulty cpu. Got replacement cpu but it did the same thing, just 7 beeps again so I returned the cpu. Have come to the conclusion that the bios is messed up, or the mobo is just done for.

What I have tried so far:
-I have cleared the cmos/power drain which still gave 7 beeps.

-Re-seated cpu, still same thing.

-Have attempted/am attempting to reflash the bios with the whole "Rename .fd file onto usb and end button boot ordeal", but even as I sit here typing with one finger and my other finger on the end key for the past like 20 minutes, I haven't heard a single beep or restart.

As of now I am out of options except to buy a new mobo. I already got a new laptop, but I was supposed to sell this one to get money for the new one I got *college student with now no money*. I read somewhere that someone went through this whole process of taking out the ram and then booting the laptop which then restarts and in the small frame that the laptop restarts they stick one stick back in and some other stuff. Was going to attempt that, but I don't remember the steps that they did and I cant find the forum again ;_;

If anybody has any solutions other than getting another mobo because I cant afford it please do tell me. I just wanna get this thing up again ;_; If any info is needed I will provide asap.

 

Also, I believe the laptop had the A05 or A08 bios before I updated it.

 

Can anyone help ;_; I found the post by Mr. Fox where he said he

1. Turn the system off and disconnect the AC adapter
2. Disconnect CMOS battery and system battery
3. Do a power drain (press and hold power button 30 seconds)
4. Remove all memory modules
5. Reconnect AC adapter and power system on
6. Let laptop beep until it turns itself off
7. VERY QUICKLY, WHILE IT IS OFF, BUT BEFORE IT ATTEMPTS TO BOOT AND LIGHTS COME ON AGAIN, INSERT A MEMORY MODULE
8. System will start to beep 5 times
9. Power system off
10. Reconnect CMOS battery and system battery
11. Replace any panels removed for access to memory modules
12. Done…

I tried this, but when I take everything out it just keeps beeping 7 times without restarting.
