Frequent BSODs

My computer has been suffering on average at least 3 BSOD a day and many seem to be different. They happen at any time whether the computer is idle, browsing the internet, or playing a game. Any and all help would be greatly appreciated!

Multiple bugcheck codes are pointing to a memory issue.
Code:
BugCheck 3B, {c0000005, fffff800030bd2e3, fffff8800d74e8e0, 0}

Probably caused by : memory_corruption ( nt!MmCopyToCachedPage+223 )

Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest86+ for at least 8 consecutive passes.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

As of right now, one stick of RAM is faulty and I'm going to check the port that it was in as well once I finish the Passes I'm doing right now

Now follow the "Part 3: If You Have Errors:" of How to Test and Diagnose RAM Issues with Memtest86+

Errors/red lines means one or more RAM is faulty. But the fault may occur due to a faulty DIMM slot, too, which is a motherboard component. Using memtest86+, you can discriminate between a faulty RAM and a faulty motherboard.

How? Say you have two RAM sticks and two DIMM slots. You obtained errors at the test with all RAM sticks installed. Now, remove all the sticks but one. Test it in all the available slots, one by one. Continue the same procedure for all the available sticks.
How to make the inference that is it a RAM issue or it is a motherboard issue? Suppose you have got the result like that:
testSlot1Slot2
RAM1ErrorError
RAM2GoodGood
It is a RAM, a bad RAM.

But if you have got a result like that:
testSlot1Slot2
RAM1ErrorGood
RAM2ErrorGood
It is a motherboard issue. The particular slot is bad.

If it is a bad RAM, you need to change the RAM. Take the other existing (good) RAM to the shop and get one of the exactly same specification. The best is, get a totally new RAM KIT.

If it is a bad slot, it is a motherboard issue. But changing the motherboard needs a preparation for most of us; so dont populate that slot for the time being.
