Getting unexpected shutdown Windows 7 64-bit BSOD

[Pixel Muffin]

I have been getting a BSOD every time I leave my computer on for over 12 hours. This has been going on for a year or so. I built the computer two years ago and had no problems for the first year. I have sent the motherboard in two times already trying to fix the problem but to no avail. I have updated all of the motherboard drivers in hopes that fixes it but that didn't work either. Can someone read my latest MiniDump file for me and tell me what is wrong? Thank you in advance!

Have you tried another power supply?

Thank you Tmagic650 For replying! The current Power supply I have is a 800W XION power supply. Thanksgiving week I read that with new ATX motherboard pins can overheat with too much wattage, so I went out and got a 650W power supply, and the computer still crashed. So I have switched back to the 800W power supply. I have also tried removing memory sticks, to no avail.

It happened again this afternoon. I updated windows to see if that would help, but it didn't. I have attached another minidump file if someone wants to look at it. Is there a minidump reader that someone would recommend? I am happy to try and look at the mini's myself, I am just skeptical of downloading any old program that claims to be anything.

Can anyone help me with my problem please?

What version of Windows are you running? Did you update service packs? Your error shows possibly Vista 0 service packs installed? Have you checked your hard drive for errors. Go back here and follow the guidelines, then we can investigate further:

Yes, I suppose the history would help.
Two years ago I built my own computer. It was just when Windows 7 was released so I installed the 64-bit. For about a year I had no problems with the hardware or the software. Just over a year later I began noticing my computer crashing after being on for 12 hours or so with a BSOD then restarting saying that "Windows has experienced an unexpected shutdown." I couldn't find a problem, so I just turned off the computer before the 12 hr mark. Then one day the motherboard fried completley. I sent the motherboard in for warranty, and got it back. They said they replaced some chip and that it should work. Soon after I realized they still hadn't fixed the problem when it shut down again. So I sent it in again, and got a completley new board (so I'm told). The new one still has the same issue. I have replaced the 800W power supply with a 650W because I read that the pins could overheat if there was too much power on new ATX motherboards, and that didn't work. I have downloaded a registry cleaner (jv16) and cleaned that up because I read that that might be the case too, however to no avail.

So here is my hardware: GIGABYTE GA-EP45-UD3R LGA 775 Intel P45 ATX motherboard --- Intel Core 2 Quad Q8200 2.33 GHz LGA 95W Quad-Core Processor --- MSI N9500GT-MD1G-OC/D2 GeForce 9500 GT 1GB 128-bit Video Card --- 6GB of Ram (Two 2GB Corsair sticks, One 2GB OCZ stick) --- Two HDD, One 500GB, one 200GB (the 500 was new, the 200 came from my old computer)

Now for the Software: Windows 7 Home Premium 64-bit

"I have replaced the 800W power supply with a 650W because I read that the pins could overheat if there was too much power on new ATX motherboards"...

First, the power supply will only supply what the motherboard needs as far as current draw, so this statement makes no sense... I'm running a quality Corsair 650 watt PS in my computer. It may not be wise to run without pairs of memory, and memory of different speeds and timings. Try removing the single OCZ stick or add another 2GB memory module if you have room. Are you over-clocking?

I took the OCZ out for a while but it made no difference. I don't have room for a fourth stick with the current case I have. If I get the crashes fixed I was planning on getting a full tower instead of a mid so that I had more room. I overclocked it maybe three times when I first built it, just for fun. But then I reverted back because it wasn't a big deal for me. I still have the software loaded on the computer but don't use it.
