Windows 7: Various BSODs and freezes on a newly built Windows 7 PC - 99% hardware

Various BSODs and freezes - Homebuilt Win 7 PC - 99% hardware issue

I got various BSODs and freezes on a newly built Windows 7 machine.
The problems started immediately before installing windows. I got the first freeze the first time I entered UEFI BIOS. After that I flashed the latest BIOS, after which I managed to install Windows 7. Once I did, I started to get the BSODs and freezes.

I tried following;

1. reinstalling windows
2. checking all the cables and connections
3. reseated the cpu and changed the thermal compound.
4. tried with 3 different RAM models
5. tried with different GPU
6. tried different HDDs
7. tried different SATA cables.
8. checked temperatures which seem to be fine.
9. cleared CMOS via jumpers and battery.

In my opinion, the only culprits could be;
1. PSU (new Corsair VS450)- too weak!?
2. motherboard - some kind of a hardware fault!?
3. case - new Cooler Master CM Force 500 - some kind of a hardware fault causing problems with motherboard or PSU?

The reason why I'm mentioning the case is that at one point I thought the freezes were triggered by inserting the USB stick into the USB drive, but I even got freezes without it, so I guess it's not it. Although I thought I should mention it.

This thing is making me crazy. I guess the BIOS freeze should point out to hardware fault. I have a terrible dealer which will charge me for testing each component individually, so I have to send the right one in for RMA. Unfortunately I can't send the whole case for testing. So please help me finding out which part is faulty.

Sounds like a Homebuilt running a FX-8370 with a "Loaded" copy of Win 7 ??

Sorry guys, I thought the "systeminfo.txt" from uploaded zip file was enough. It's a home built Windows 7 x64 with following specs. I attached the hardware report summary from aida.

In short:
CPU: AMD FX8300 with stock cooler
MBO: Asrock 790 Pro3 R.20
RAM: Kingston HyperX 1866 2 x 8Gb
GPU: Asus Strix 750Ti 2gb
HDD: Seagate 7200 1TB
SDD: Kingston HyperX 120
PSU: Corsair VS450
CASE: Cooler Master Force 500

I also attached the bluescreenview dump summaries.

Guys this is just a test build. I doubt it is a software/driver issue. It would be great if someone could take a look at the hardware strings in dump files, as I am quite sure it's a motherboard or PSU issue. I just need to know which. I tried to look myself, but I guess dump analysis is a little bit above my knowledge level.

The fact that you froze in bios is unusual, so its obviously a hardware problem unless your bios itself is bad. You said you reflashed it already so the bios is probably okay, however you might try flashing in DOS if that's not how you flashed before. Aside from that, I'd try booting into Hiren's Boot CD or UBCD and playing around with their programs for a while with a hardware environment of a different psu, no hard drive at all, just one dimm, and the slowest video card you have. Doing this removes the burden of dual channel memory timing, a potentially bad hard drive, the power burden of a high powered graphics card, and windows. If you are stable doing this, you can then slowly add back in your components and note which one causes problems.

But if you are not stable in this minimal environment, I would remove the cpu then inspect both the cpu pins and the cpu socket very closely with a magnifying glass. If it looks perfect, do the same with your dimm sockets and your dimm pins. And if they are perfect, you probably have a bad motherboard.

Too much pain to think clearly enough to look at the dpm files but I'd think that if the problem started as soon as the PC was built it's time to disassemble it. If You don't have a "build board" the MOBO could just be placed on a non-conductive surface like the box it came in. Hook up the POST speaker and do like John posted above running on minimum hardware. If there's No POST problems (Your MOBO Manual will show if something's wrong by the beeps) then hook up the OS SSD and stress test the CPU then the RAM modules one at a time. Newegg has some great YouTube vids on assembling a PC that You might want to watch first.
