Solved Pc crashes when I do certain tasks with a GPU installed

July 1, 2013 at 11:40:59
Specs: Windows 7
I recently purchased a gaming PC from IBUYPOWER a few months ago. Everything seemed to be fine until a few weeks ago my PC would crash randomly when playing certain games, or rendering a video. I did some trail and error. It only seems to crash when I have a gpu installed. I've tried both my old GPU and my new gpu and I still get the crash. I've tried a lot of things such as sweeping my drivers, taking out ram, underclocking my gpus, changing around bios settings overclocking even. When I do my tests/game/render, my temps are completely normal

I am thinking this is a power supply issue and I want to see if there's anything I can try before sending my power supply back so if anyone can shed some light that would be appreciated, thanks!

Motherboard: ASROCK N68-VS3 FX
CPU: AMD FX-8120 3.1GHz
GPU: HD Radeon 6850 1gb
Memory: 8.00 GB Dual-Channel DDR3
HDD: Seagate 1TB 7200rpm
Case: Azza Solaris Mid Tower

Oh and to add; I can replicate the crash very easily. Rendering a video is guaranteed to make my pc crash. I crash when playing certain games but it's pretty random. And another thing, the crashes aren't BSODs, just my pc just shuts off.

According to CPUID, you are running the 125W version of the CPU. Your motherboard can't supply the current properly for that processor as it is rated for 95W max.

"I recently purchased a gaming PC from IBUYPOWER....I am thinking this is a power supply issue"

If you accepted the standard PSU rather than selecting a decent one, I can almost guarantee the PSU is the problem. You listed all the rest of the hardware, why didn't you post the make/model/ wattage of the PSU?

You didn't provide any specs for your PSU. We will need specs before we can determine if that is really the issue.

Oops, thought I added the power supply

atx 600wat model sl-8600eps? That's what it says on the side of the PSU

If you recently purchased the computer it should still be under warranty. Have you spoken to the retailer about your problem?

That PSU is manufactured by Solytech but apparently sold under different names. I was kinda surprised that it gets really good reviews.

I suspect the problem is your board supports 95W CPUs and your CPU is 125W.

I see there are some 125W CPUs listed in the support list at Asrock, even though the specs for the board state 95W CPUs.

Are you disabling the onboard nvidia graphics?

Well, This problem only started happening a few weeks ago. Before my computer worked fine. What would disabling the onboard graphics achieve?

Onboard is nvidia, add in is AMD. Different drivers required.

I think Othehill is right, looking at the picture of the motherboard there's no cooling on the MOSFET's. I googled and found out the board has 2+1 phase count which is not good at all for power hungry chips like AMD FX series. The board is gonna die (MOSFET's are gonna burn) if u don't change the chip soon.

I will put this here if it will help at all

This is my hwmonitor at when I am just Idle, I played a match of Dota 2 without crashing. The crash only comes when I render or play BF3.

I think OtheHill & kuwese are on to something regarding the CPU. Your board only supports up to 95W CPUs & there are 2 versions of the FX-8120. One rated at 95W, the other at 125W. Are you sure yours is the 95W version?

I didn't pay close attention to the board specs until now & I have to ask - why would you choose an AM3+ board that's been retro-fitted with a 6 yr old NVIDIA chipset combo rather than a board based on a modern AMD 900-series chipset that's designed for the FX CPU?

I can't seem to tell but this is what I bought:

If thats the case why can I render without crashing if I take out my Graphics cards?

When the card is installed, are connecting the 6-pin PCIe plug?

Okay, I figured out something

A while back I had a problem with my GPU usage dropping randomly, causing me to drop a lot of fps to unplayable levels.

I read up on some things and found it was a setting in my bios called "cpy thermal throttling" I disabled that and everything was fine, no more gpu usage drops.

I tried enabling it again and guess what, the crashes stopped. BUT, I seem to have the GPU Usage problem again.

I probably should start another thread but if you have any ideas let me know, thanks for the help

You didn't answer if you are connecting a separate 6 pin power connector to the graphics card. Without it, the card will not have enough power under load.

The square 4 pin connector supplies power directly to the CPU. The CPU can pull 10.5A@12V. The add in GPU can draw 131W. The PCIe x16 slot supplies 75W of that (6.4A@12V). The rest (approx. 5A@12V) is supplied by the second 12V rail of the power supply. The RAM and drives draw more current.

Did you install the latest Radeon drivers for your card/ OS?

Don't start another thread. You have several helpers working here now.

I made sure I have the 6 pin is connected, what now?

This is what I'm talking about btw:

Also yes, I have the current drivers

So I have to get a new board then huh?

Should I do that or straight up send my PC back? If I have to get a new board, what should I get?

Send the machine back if it is still under warranty.

For 125W CPU u need at-least 4+1 phase (with the heatsink on the MOSFETs) board if u don't plan to overclock.

An update: I fixed it. I did a lot of looking around in the bios setting and messed around with the OC settings. I changed it from auto to manually setting the clocks and such and that seemed to have fixed it.

If you are overclocking the problem will probably return.
