Solved Just built a new PC - Constantly get random crashes!

Specs: Windows 8 64-Bit, AMD Athlon II X4 3GHzz / 8 GB RAM
Okay, so I just built my first PC with the following specs

- AMD Athlon II X4 640 Processor
- 2 x 4GB RAM
- Biostar A780L3C Motherboard
- Seagate 500GM Barracude HDD
- Saphire HD 7750 Graphics Card
- CIT 400W Power Supply

With completely default BIOS settings, I experience small but extremely annoying crashes in almost everything. In google chrome, I experience the 'Aw Snap' page multiple times, Internet explorer I get 'Internet explorer has stopped working', Firefox crashes too, also Minecraft crashes to desktop randomly every 5-10 minutes, and it also happens with GTA IV. Everything, even the plugin (Adblock) That I have for Google Chrome, crashes all the time. Even trying to load this page was a problem.

Is there anything in my BIOS I can update, or is it something to do with my hardware?

I need help in preventing these crashes, and so would be very appreciated.

✔ Best Answer
You have a piece of crap $15 power supply for one thing. I can't find any real specs but that unit supposedly has 2 +12V rails. That means 1 for the motherboard and 1 for everything else.

Most likely your system is under powered.

I suggest you download and install HWMonitor. Run it in the tray by the clock to monitor temperatures and and voltages in real time. Voltages for all rails should stay at +- 5% of specs. Get HWMonitor from the link below.

Did you install all the drivers that came on the CD with the motherboard?

Did you buy the retail version of your Athlon II?

What exact RAM do you have? Did you buy a dual mode package?

I agree with OtheHill, that piece o' crap PSU has got to go. And you didn't supply the RAM specs. Is it a matched pair of DDR3-1600, CAS 9, 1.5v? It should be. Did you test it with memtest86? Did you manually configure the BIOS settings or just load the defaults?

And out of curiosity, why did you choose that particular motherboard & CPU?

Well as you can tell, I am pretty new at building computers. I now seem to understand that it would be worth ordering a new PSU. The reason that I had chosen such hardware is because I was running on a cheap budget of around £300.

The RAM:
Komputerbay 8GB (2 X 4GB) DDR3 DIMM (240 pin) 1333Mhz PC3-10600 / PC3-10666 9-9-9-25 1.5v

I have installed HWMonitor, and it means nothing to me. Is there a way I can add a screenshot?

Also, the CPU was retail packaged, from Amazon. Here's the link

The BIOS settings are set to Default. I did take a look at them, however I never had any idea what most of the settings did, so I gave it a miss.

HWMonitor should show you voltages like 3.3V, 5V & 12V. To the right of those values are the measured voltages. All should show readings that are between 95% & 105% of the value to the left.

Your Athlon II should be listed there. The idle temperature should be lower than 40c, preferably lower than that. The system temperature should be 5-10 degrees lower than the CPU.

Your graphics card should also show up. Idle to full load will be a wide spread.

If you post all the temperatures we can help. You can also post a screen capture. Just below the Post Reply at the top left there is an "Add a Screen Capture". Follow the prompts.

HWMonitor Status
Thanks. I've put out a small recording there to show you whats going on, I hope it's alright.

The PSU voltages are way out of whack. A 5% +/- tolerance is generally acceptable but yours aren't even close, especially the +12v which is THE most important. See if you can find a deal on a Corsair 430w unit.

Sure. You want me to order this exact model correct? I'd be happy to get it as long as it solved the problem. Thanks for all of the advice!

Yes, it is a very good quality power supply that should fit any reasonable budget. Yours has numbers that I have never seen before and considering it is new, the manufacturer should be ashamed to sell it and the store or online store should be ashamed to sell it (return it for a refund, accept nothing less). Pure crap!!!

You have to be a little bit crazy to keep you from going insane.
