Having BSOD issues

[JimmyJimmy05]

Hey, guys. I've got a machine that I've been having a lot of trouble with. I bought the computer from a guy that had built out for gaming the specs are as follows:
16gb Ram (4x4)
128gb Samsung SSD
1tb HD
Geforce GTX 670 windforce edition
8 core 3.1ghz AMD cpu
750watt PSU
Asus motherboard
Windows 7 ultimate

So everything went well for about 6 months, then some seemingly random BSODs started happening. They were infrequent and out of laziness I chalked it up to driver issues. Eventually they started happening more frequently and I started getting worried. I rolled back drivers, I updated drivers, I did everything I could think of. I just couldn't get the problem nailed down, but the computer was still usable for the most part. This continued for a month or two until the computer was basically useless. I didn't want to start it up for fear that I'd ruin everything, but I guess it was too late.

I've since reinstalled Windows, replaced the graphics card, replaced the motherboard, run every memtest and hard drive error checker I could find and still nothing has helped. I can run the computer in safe mode and it will be fine for days, but as soon as I try to start Windows proper, it will work for 5 minutes, max, the Blue Screen with an unknown hardware error.

I've read that driver issues can cause this, but the only updated drivers I ran were for the graphics card, but I rolled those back and formatted my drive and downloaded fresh drivers and it still didn't help. I've also read that it can be overheating issues, but the CPU heat stays steady and pretty cool, plus the case has great airflow.

I'm at my wit's end and the only thing I can think of is replace the CPU or psu(which I probably should have done first) but I'm sick of throwing money at the thing. If anyone has any advice or knows what might be going on I'd appreciate any help. Thanks in advance.

If you are actually getting blue screens, you can try to use WhoCrashed:

Maybe it will tell you the offending driver or other problem.

start with one dimm and no video card use onboard video. make sure the new mb bios is up to date use memtest 86 from boot disk over night. if the ram passes try another stick. run memtest on all 4 sticks. if the system is fine with one stick add another. if it fine swap one stick see if the error comes back if not. put in all 4 sticks and see if the error there. if it pops up with 4 sticks try three. some mb and ram with 4 sticks issues can happen unles you bump the dram voltage. with the ssd make sure it has the newest firmware. also ruin hdtune read both drive health.

Well, the motherboard doesn't have on board video, so I can't really run it without a video card. I have one-by-one run the computer with only one stick of ram in and it still crashed on each stick. I doubted that they all went bad at the same time and then I did run memtest overnight one night and everything went perfectly fine over 5 passes. I assumed that meant that it was okay. Should I still run it on each one individually again? I will try to run hdtune and download whocrashed tonight. Thanks for the replies, guys.

for testing see if a friend has another video card. it help rule out if it a bad video card or bad power.
