Complete System Instability


Recommended Posts

Hi everyone :)

I've had my AMD FX rig for less than a year and from day one I was plagued by random crashes during gaming, sometimes it came up with a BSOD, sometimes a black screen then CTD. I have replaced the following components:

- GPU (Now HD7770 GHz Edition)

- RAM (BSODs and CTD occur with both sticks in all slots)

- SATA Cable*

- PSU (From El-Cheapo to Cooler Master)

 

And have made the following changes:

- Set memory ICs to Unganged

- Set LLC to 'Extreme'

- Reformatted to Windows 7

- Underclocked CPU*

 

For reference:

- BIOS is up-to-date with F6

- Graphics drivers up-to-date with Catalyst 12.10 drivers

- Memtest86 passed

- Ran OCCT a while ago with no errors, but can repeat if needed

- PC is generally stable for web browsing/Office etc. (unless underclock applied - see below)

 

* = Issue occurred less after that, then gradually came back with increasing frequency

 

At first, I thought the issue was graphics card related, so I spent

This may sound funny but I've seen this happen because of a keyboard or mouse.... my room mate has a wireless keyboard that will randomly crash the system.. replaced it and the issue dissapeared.

 

if nothing else resolves it, try replacing or disconnecting any un-needed usb devices.

Will try that now :)

It sounds like a completely wired issue to me. You can try to run the PC using minimum config (i.e. one RAM, one HDD, no USB devices except Mouse and keyboard.

 

Scratch that.

Your problem is happening due to atikmdag.sys which is part of catalyst.

The only solution I can find is the complete re-installation of catalyst.

I've reformatted the computer multiple times, used multiple versions of Catalyst, installed driver-only versions of Catalyst. I've reinstalled Catalyst many times yet the issue recurs, so I'm pretty sure it isn't software-related. sad.gif

Thanks for the suggestion though thumbsup3.gif

 

Oh and a quick update: It isn't the WiFi card, keyboard, or mouse causing the issue, I've checked in different ports and using different equipment but the issue recurs unfortunately

I'm thinking this could be heat problems, TMPIN0 and TMPIN1 are hitting 50C at idle. When I removed the CPU heatsink there appears to be very little thermal paste, so I'm assuming these temps are for the Northbridge or the CPU. I haven't seen these values so high before, so I'll try and get hold of some thermal paste to put on my CPU heatsink and see if it makes any difference.

 

Update: Moved the thermal paste onto the copper heatpipe on the CPU cooler, temperatures are now 37-38C at idle.

Okay I notice you said you moved the RAM around but did you try a whole new set? Also concerning RAM are you setting the speeds or are you letting the motherboard auto set the speeds?

 

If the heat, RAM and PSU are all checking out and still having the issue you might have a motherboard itself that is bad.

I used a spare 4GB stick I borrowed from a friend to test the slots

I'm letting the motherboard detect my RAM speeds, although it is detecting a 1600MHz kit as 1333MHz if that makes any difference

The CPU is currently running AIDA64 at 26C ambient temperature, the CPU is hitting 57C max so I think cooling should be okay?
