BSOD - Most likely RAM issue

Is it the motherboard making the beep?

That would indicate a hardware fault.
Is it a repeating beep series?
Could be one beep repeating or long/short combinations, etc., just note the series example: one long two short.

The 'Cold Boot' issue is usually due to CPU and/or RAM voltage being too low.

Can you download CPUZ and post a snip of the CPU, Mainboard, Memory, and SPD tabs.

What are you using to check your CPU temperatures?
Use Core Temp, to check the CPU temps when at idle, under load and/or testing.
Let us know the minimum and maximum temps you get.

Go to your BIOS and let us know the DRAM voltage, the NB and integrated memory controller voltage, if your CPU has that feature.

Check the PSU voltages when the system is cold (with system cold go to BIOS), and again when the system is warmed up. Post both cold and warm voltage settings.
In your BIOS check the output voltages of the PSU. Power > HW Monitor Configuration, VCORE Voltage, 3.3V Voltage, 5V Voltage, 12V Voltage.

Then check the CPU Over Voltage, Memory Over Voltage, (CPU/NB Voltage should be) VDDNB Over Voltage settings, and post them here.
In BIOS, Advanced > Jumper Free Configuration.

Passing memtest86+ doesn't mean that the RAM has no issues, just that it didn't have an issue during the test.
RAM issues can be very elusive and difficult to find.

What are the RAM settings you put in?

Did you get a chance to get the 'warm' voltage settings?

The cause can still be many things, RAM and CPU settings, bad RAM, CPU, motherboard or PSU, to name a few.

I put in 5-5-5-15 timings and 1.8v in my BIOS settings.
I looked at the newegg site to see what timings and voltages the RAM were after a friend suggested to add them.

Another problem has arisen. Sometimes when I load my computer, in the dark areas(more visible) will be little pink pixels that seem to flicker about on the screen. The screen will then turn on and off(gooing black) every few seconds then after a while will return to normal.
I took a screenshot during the bug and when it fixed itself the pink pixels didn't show.
Gonna try using a new HDMI cable.

And I ran Memtest86+ for 30 minutes and it got some errors then Memtest froze.
Coudl this mean the new RAM went bad too?
