Windows 8.1 crashing HELP!

[buiscreep55]

I've built a gaming pc and installed a retail copy of windows 8.1 but it crashes a lot and I don't know why.

My PC Specs are:

Intel core i3 4130
nvidia gt 640
8 gb ddr3 1333 mhz ram
Gigabyte z87 hd3 motherboard
1 tb hard drive

These are all the errors I've seen:

Bad pool header
Driver irql not less or equal
kernel security check failure
memory management (This is the rarest one I've seen)

Please can you reply - this is really frustrating me

If you have two RAM sticks, try removing one of them and see if that helps. If not, try the other one and see if that helps.

If it works with one of the RAM sticks then you know the other is bad and need to be replaced.

If you only have one RAM stick then see if you can borrow one from another computer to test.

Can you run memtest86 for at least 8 passes and tell me if you find any errors?
If not, we'll continue the diagnosis.

Thanks!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!.

did you test them like I asked you to?

memtest86 would be the first thing to use to check your actual hardware. If that is ok, then run malwarebytes to look for virus issues.
if that is ok, make sure you are up to date on your windows updates. if you are still getting these type of errors they are most often caused by a device driver that is overwriting another device drivers memory. This will be cause by a third party driver (windows update replaces broken microsoft drivers)
and you will want to go to the various vendors websites to pick up the updates. All that being said, there are common drivers that cause this problem over and over on systems. USB 3.0 port driver and devices depend on updated cpu chipset drivers and tend to corrupt memory if you don't install the chipset driver updates. here is the intel drivers for the intel cpu :https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=20775

oem overclocking drivers and old hardware monitor drivers also tend to corrupt memory.

anyway, the memory .dmp file will contain a list of the installed drivers and info. you can post it on a cloud server and it can be looked at with a debugger.

you can also use the driverquery.exe command to look at the drivers installed on your system.

I forgot to say this but two of my ram slots are faulty.... could this be causing the crashes?

This is weird but when I'm rendering a video I don't crash...

if the RAM slots are in use, any device driver copied into the bad section of memory can be corrupted and cause a bugcheck.

So, how can I fix?

If two RAM slots are physically broken then you have to remove the RAM from them and not use the two slots or replace the motherboard. Generally, people might think their RAM slots are broken when all they get a memtest68 failure but often they really only need to update the BIOS or hard code correct memory timing settings in the BIOS. (or increase the memory voltage slightly if you have 4 RAM slots in use) It is pretty common that a BIOS will not correctly set secondary memory timings (might be fixed with a BIOS update)

I have 4 RAM slots but 2 of them are faulty. But I do have my RAM sin the working slots

if the RAM is in working slots and passes memtest86 then the two unconnected slots will most likely not be the cause of any problems.

I was looking ar memtest86 and it said For 32 bit cpus or operating systems - I have a 64 bit pc

I've recently taken out 1 stick of ram and I haven't crashed But, I am still worried that it will
