New Build Randomly Freezes

post #1 of 6
Thread Starter 
Hey guys, I just built my first good desktop and am having some problems. My build includes:

Motherboard: Gigabyte P67A-UD4-B3
CPU: Intel i5 2500k
RAM: Corsair DDR3 1600 (2 4 GB sticks)
Graphics Card: EVGA GTX560 ti
Power Supply: OCZ Technology 700 Watt
OS: Windows 7 64 bit

My issue is this: My desktop will randomly freeze. The screen will stop and freeze and the last sound that was played will repeat. No blue screen or any kind of error message is displayed. Resetting the computer will fix it. My CPU temperatures are around 33 C. The computer randomly freezes, sometimes it takes 10 minutes to freeze and other times it takes several hours.

What I have done so far: I have asked a few of my friends and they have suggested to reset the RAM and the graphics card. I did this and the computer still froze after some time.

I am new to this site but my friend talks very highly of it. Any suggestions or questions are welcome.

This sound like it will be a difficult problem to fix.

1.) What were you doing when it crashed? Playing a game? Does it tend to crash when it first starts up, or when it's been running for a while? Are the crashes random? How often are the crashes? Every 10 minutes or once every few days?

2.) It is probably either GPU, CPU, or Power supply. I would use stress tests (found in the OCN download section) to identify the bad part.

example: Stress test the CPU. If it consistantly crashes within 60 seconds of starting up the stress test, then your CPU is bad. If the CPU stress test causes it to crash just as often as before, then it's not the CPU. Repeat this process for the GPU.

Use a multimeter to verify the outputs of the power supply. (found at radio shack for $10)

Sorry, i wish you the best of the luck!

Hey thanks for the advice. When my desktop freezes it's typically under low stress with just an internet browser and maybe 1 or 2 other non-intensive programs are open. It tends to crash after maybe an hour to 2 hours of it being on although it has crashed much earlier and much later than that.

I am running Prime95 to test my CPU right now (I'm writing this from my laptop) and it seems to be working just fine. CPU temps are between 80-85 C and there have been no crashes or anything. I'll test my GPU next and then the power supply.

Like I said I just bought and built this desktop and so hopefully I can identify the issue before 30 days so that I can return any components to microcenter. Thanks for the help and I'll let you know more soon.

I would guess the problem is driver related or something wrong with your hard drive.

do the error scan with HDtune

Oh, i forgot, you can test RAM too! OCN downloads sections has tests for that.

I'm feel really bad for you. This problem is probably gonna take a while to figure out.

Here's a summary of what I've been able to find out:

Ran Prime95 (CPU torture tester) and it ran fine but the CPU was very hot 80-85 C

Ran a GPU intensive task (3D Mark11) and no problems

Talked to a Micro Center tech and he suggested it might be a hard drive issue. My hard drive is a Seagate 160 GB. I ran SeaTools on it and no errors came up although it did freeze during the long read test.

I noticed that the RAM was running at 1333 MHz even though it is designed for 1600 MHz. I went into the BIOS and set it to 1600 and it works fine but still freezes.

I am currently running the computer with only 1 of the 4 GB sticks in it. It is running fine and has been for a while. I plan on switching it out for the other stick and seeing if the freezing issue occurs. If it does, there is a good chance that that stick of RAM is bad.
