Well, as the title states, I'm having some issues isolating the problematic part. So, here's the scenario of what brought me to this:

I was trying to play Starcraft II, and it worked for a while, and all of a sudden it would give me something like

ACCESS_VIOLATION (0xC0000005)
occurred at 001B:00D8F596. The memory at '0x00000000' could not be read. (it was very similar to this message, if not the exact same)

Afterwards, I figured it may be the game, so I test out some games that I've had working in the past, and they all start smoothly enough, running for upwards of 5-15 minutes or so, and then booting to the desktop. Some of them didn't give me error messages, but I made the assumption that it was the same type of error.

Anyway, after I thought it was the hardware, I tested the memory, because it sounded like a memory issue, with memtest86, and went through upwards of 20 cycles, and the memory tested perfect, with no errors. Next, I decided to stress test with Prime95, and I'm not sure exactly what it's telling me, but here's what it says after most tests:
FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware Failure Detected, consult stress.txt

So, at this point, it's at some point in the data moving that is screwing up, and I want to say CPU is the issue, but I'd like to be 100% sure. In the case that the path to the CPU is messed up, it could cause numbers to change on the way; in turn, screwing up complicated processes like games, but not seeing many issues in regular OS function.

I think I've covered everything, but if there's something else I should post, let me know. Thanks!

How old is the system? What are system specs?

I am a retired Ford tech. Next to Fords, any computer is a piece of cake. (The cake, its not a lie)

3770K @4.5, Corsair H100, GTX780, 16gig Samsung, Obsidian 700 (yes there is a 700)

The cpu and other components start to glitch when the computer overheats.

Please perform the following so that we will be able to see the specifications for this computer.

Post a Snapshot using Speccy.

As DaChew suggested, heat can cause this type of problem. If this is a desktop, open the case and inspect it for a build up of dust, specifically in the fan and heat sink assembly on the CPU. Also look for a dust buildup on the graphics card and a fan if it has one. If there is a build up of dust use canned air to blow it out.

If this is a laptop, about all you can do it use the canned air to blow it out from the vents in the case. Anything further would require some dis-assembly.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Here are my specs: System Specs

I used canned air recently to clean it out, but if you think I should again, I will. Also, it's a desktop PC. I'm not sure it's due to heat, because my case was built for heat -- Antec Nine Hundred Two, with a large 200mm fan on top, two 120mm fans on the front by the hdd, and another 120mm on the back, including all the other fans attached to components.

EDIT:

How old is the system? What are system specs?

Most of the system (motherboard, memory, and CPU) is 2 years old, save the video card which is less than a year old.

Would you run coretemp please and get a temperature reading after the cpu has been fully loaded for a few minutes?

What cpu cooler are you using, have you reseated it and used premium paste?

No. Try not. Do... or do not. There is no try.

Coretemp:
It says:

Core #0: Low:48degrees High:53degrees Load:9%
Core #1: Low: 48degrees High:53degrees Load:3%

Both loads are changing, though, up and down.

As for CPU cooler, I have whatever cooler came with it. I'm not sure how to find out. I'm not sure what premium paste is, though.

I think we have found your problem, those core loads are almost idle and 50+C is too high.

So, should I go out and grab a nice heatsink and some paste? Is that likely the problem?

Max Temps 55-63


Max load of both cores would probably push it that high or higher.

Shine a bright light down thru the fan on the cpu, there might still be a lot of dust.

Thermal analysis

:thumbsup:

http://www.thetechlounge.com/article/562-1...FTW-Video-Card/

That video card is dumping it's heat very well, the heat rises and the stock HSF can't get enough cool air to keep that cpu down in the 40's where it should be.

Your case is a very good one
