New build, freezing and restarting, getting faster. PSU?

Greetings Tom's Hardware Forums!

Some backstory:
Less than month ago I finished building my new PC!:D I had the 32 bit version of Windows 7 installed on the machine as I waited for the 64 bit one to come in. Two weeks ago I attempted a fresh install of the 64 bit version of Windows and the machine froze up during the installation. The keyboard lights were off but the fans were still spinning. After some reformatting and a few retries, I finally got it on there. It didn't freeze for about an hour.

Now to the problem:
The machine freezes up and occasionally restarts on it's own. If it doesn't happen immediately, it won't happen at all. When I restart it (or it restarts itself) it does the same thing, but seemingly gets faster. Eventually I can't even get to the login screen, of it won't display anything at all. I assume this because it never reaches post. If I unplug it for a day, it lasts for an hour of two, and does the same thing. One time I tried to turn it on again, and It sounded like a car struggling to start up.:??:

I've tried a different outlet, reformatted the hard drive, removed the hard drive, reset the cmos, and replaced the thermal compound. It continues to do this, even in bios. In bios the backlight of the keyboard shuts off, but the num-lock and caps-lock lights stay on, even after shutting down the machine. I went into bios and it looked like a glitchy mess.:( It doesn't seem to be restarting itself anymore. If the monitor is off while it happened, it's not showing any signal. I don't want to update the bios now because it could freeze again.

Could you please help me?:??: Any advice is much appreciated!:D

Specs

CPU - AMD Athlon X2 340 3.2GHz Dual-Core Processor
Motherboard - Biostar Hi-Fi A85W ATX FM2 Motherboard
Memory - Kingston XMP Blu Red Series 8GB (2 x 4GB) DDR3-1600 Memory
Storage - Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive
Video Card - Zotac GeForce GT 630 2GB Video Card
PSU - Corsair Builder 430W 80+ Bronze Certified ATX Power Supply
Wireless Card - TP-Link TL-WN751ND
OS - Windows 7 Home Premium 64 bit
Case - Xigmatek Recon ATX Mid Tower Case

Here are the voltages according to bios.

Here's some more info if you need it!

Extra stuff

Note the installation cd had a "plain" install and a UEFI install. I used the uefi install and had no problems until yesterday.

Also, what do the numbers on the mobo's lcd mean when it's not in post or bios? When it freezes, it's usually stuck on 10 or in the 90's.

Trying it right now. One stick froze at an hour, the other has run fine for an hour. I'll update in another hour. Wouldn't there be a different post beep?

Nope, never mind. I powered it on, ran windows, and it only lasted thirty minutes. The machine stuttered at random. This time it rebooted itself. I noticed the GPU fan shut off, though.

The bios issue was solved when I plugged the machine into the monitor (DVI) instead of the TV(micro HDMI).

Any way I can verify where the problem is coming from?

Have you installed the newest drivers .. etc? Have you run stress testes? On your RAM Memtest and etc. ? Have you checked if nothing is overheating? If you still have the problem take your PSU and try it on another PC, if it freezes again then the problem is the PSU, if there is no problem try the same with the RAM. One stick, two sticks and etc, but if there is a problem with your RAM for sure Memtest will say it all. But first check all the system temps :)

* Edit * Well you said that the GPU fan turned off, then the GPU is overheating also the Athlon have no intergrated graphics, does it? Your motherboard too? If them both have no intergrated graphics then GPU is the problem. Also that explains why it freezes sometimes.

Oh, here are the temperatures.

Memtest froze when I was testing the memory. I don't have another tower to test the PSU on, only an iMac.

As for gaming, It worked when I ran something simple like Antichamber or FEZ, but the freezing only happened when I wasn't doing anything heavy, such as web browsing or Idling.

Just send the ram back and want another one. Faulty RAM but if you still have the problem PM :)

Just making sure, both sticks of ram that shipped together are faulty? I've tested everything in bios and it still freezes. The GPU fan only stopped that one time.

Not so fast, unfortunately memtest failure simply means the PC errored running memtest - could be bad or incompatible memory, but it could also be motherboard or PSU, or anything in operation at time of crash. If it crashed while only one stick of the two was in there then I'd say bad memory but it is kind of unlikely both would be bad. So you are still in the process of switching out parts to isolate the culprit. If you only had another stick of ram, any compatible ram, then you could test using it.

Sadly, I have nothing else to test with it. Could the GPU be causing this? It stuttered a little today and froze again. once it even displayed "NO SIGNAL" and my keyboard was unresponsive. Also, it's fan shut off once while the other fans were funning.

Yes. The fan stopping is suspicious but even minus that the GPU is one of the suspects. I just might start there myself. It's just too difficult to say where the issue is exactly so you may have to trust your intuition as to where to start replacing. In cases like this it makes sense to start with the easier and less expensive things first. Also you could buy replacement parts from a source you could return them to need be.

Well, the PSU is from a reputable brand, the CPU is expensive, and I don't think the motherboard or the wireless card could cause such a thing. The motherboard only takes care of bios and carries the power, right?

I'll replace the GPU and the RAM. If that doesn't work I may have to replace the PSU. It's the only thing I could think of that would cause that "dead car" effect. The motherboard seems to work fine.

Haven't replaced anything yet, but I really don't think it's the GPU or the RAM anymore. I've unplugged the GPU, the wireless card, and the hard drive. I can't get any video output here but the keyboard lights say it all.

I'm thinking it's the motherboard, like you said. The CPU temperature never went over 32C and It's unlikely that both sticks of RAM are bad. It could also be the PSU, but I'm having more suspicion about the motherboard's behavior.
