Computer Keeps Freezing!

I've suddenly got freezes as of last night. They are random at best. The rig is pretty much new (3 weeks) except the SSD and GPU, they are a year and a few months old. The freezes tend to either black out (can some times still hear sound) or the screen just goes white/blue freezing. I removed my overclock and my AMD driver and put back my old 13.12 driver. Which I ran 3DMark, and just as it finished I went to check the results and the screen just went white.
I've now underclocked my GPU (R7970 Lightning BE) and it's made it through a couple of runs of 3DMark without it crashing.

Hi Demon8991

I had a problem with my system freezing back in March this year. The system was a new build from OCUK. After a couple of weeks I noticed the system would freeze at random times but never whilst gaming. I RMA'd the system back to OCUK who put the system through a few tests, but they couldn't get it to freeze like it was for me. I thought I was going mad, but eventually after them having it for a few days it did freeze, and from the reports they had on the fault it was the graphics card. The card I had was the Gigabyte GTX770 2Gb OC Windforce 3, they replaced the card and ever since then the system hasn't missed a beat. (Touching wood now)

I know you have a totally different graphics card to me so it might not be related. Just thought id let you know my experience.

Before the problem was solved I had tried the following

Fresh install of windows on two separate SSD's.
Updated BIOS on Motherboard
Rolled back drivers on the graphics card.
New set of RAM installed
Disconnected the whole system and re-wired it

That is interesting, I really hope it isn't the GPU as the 7990 isn't made anymore and I don't think AMD/Gigabyte would give me two GPUs to compensate for it.

have you tried it with just windows boot ssd ie without 2x Samsung F3 1TB RAID 0 l 2x WD Red 3TB RAID 1

I will make that the next thing I try! Could it be a faulty stick of RAM or does sounds unlikely?

I find it strange that the crashes only occur when the system is idle or browsing the net. I have never had an issue when gaming or putting the system through stress.
 
So I am now running the 14.4 WHQL drivers but was having the issues with the 13.12 as well that had previously been running fine since they were released in December.
 
what amount of dram voltage you using? if it freezed from a cold startup its usually cpu voltage or memory/memory imc voltage related

you could try 1.55v dram v

and +0.040v offset
 
I have never touched my ram voltage as I have never overclocked it. It has always been at the default settings and been fine, out of interest how would that have changed?

RAM is currently set up one XMP/Profile 1 which I changed last week, previously it was just set manually to 1600Mhz.
 
when did it start locking up?

and added any new parts or overclocked since the lockups? was it fine before?

I still put it down to ram or cpu voltage but could be something else
 
No I have changed nothing which is so weird.

I haven't had enough time to see if it will crash on one stick of RAM yet but it didn't last night.

I have also read that some times ASUS AI Suite can cause some problems so it might be worth me uninstalling that maybe? I also run AIDA64 as it has an LCD read out on my Logitech Keyboard.
 
I run asus ai suite fine but on z68 board,also use aida64 without any trouble but worth disabling/uninstalling them for testing

ram might need a bump in dram voltage,i ran some corsair vengeance that needed 1.55v,they would freeze sometimes if on 1.5v,again worth testing to see as it wont hurt the ram ect

are you 100% sure the m4 is on latest firmware? as that has well known 5400 hour use freeze bug

Ok well I will bump the voltage up and see how it performs I do find it strange that it has ran for two years at whatever voltage it is now and now it is having issues.

The M4 is on the newest firmware as is the bios as I always ensure these two things are updated and I check frequently.
 
could be psu degrading or memory slightly

could be anything but all you can do is test the things that wont cost you anything then move onto replacing parts

Nice one thanks!

I will make sure to do all of the suggestions and see it makes any difference.

Is there anyway of testing the PSU?
 
Ok it just froze again, this time with one stick of RAM in the motherboard.

I have removed that stick and put the other one back in the other slot and have raised the DRAM voltage to 1.55v.
 
I don't suppose you have tried running your system, using the on-board graphics. That will probably rule out the graphics card if its still freezing...

Yep that is my next step if I get a freeze on one stick of ram @ 1.55V.

I am just praying that it is not the GPU as I don't see myself getting another one.
 
Ok so I though I would provide an update.

I ran my system on the other RAM stick in another memory slot at 1.55V and I had no issues over the last few days apart from low memory warnings when I was playing Tropico.

I decided to put the other RAM stick back into PC but it was now in a different slot and kept the volts at 1.55V, the sticks have now swapped positions from there initial locations. I haven't had a single issue now since Sunday.

So without jumping the gun I think upping the voltage from 1.5V to 1.55V has fixed my problem. Does RAM really degrade that much to require a bump in voltage every couple of years?

Massive thanks to everyone for your help.
