I have had a problem for a little while now where my PC will crash during gaming. It will just freeze up anywhere from instantly to sometimes up to 10 minutes after starting the game and the only way to 'free' my computer is to hold the power button down and hard reboot it.

I can play things like League of Legends or Hearthstone fine and do endless amounts of stream watching or browsing without any lock ups.

I recently ran Video Memory Tester and it confirmed errors to which I sent my graphics card back to the manufacturer. They tested it and said there were no faults but sent me a brand new one anyway, after fitting the problem persisted.

On a hunch I retested my memory with mem86+ and identified a faulty stick of RAM, thought I finally found the problem but I still get crashes.

I just tried to run PassMark and it gets to the stage of running 3D tests in full screen and then locked up while testing.

I have fully updated drivers and BIOS and check for new ones regularly.

I am truly at a loss for what else I can do or check to fix this... Any help or ideas on what to look at next is greatly appreciated.

Hey Marshall86,
This is truly a weird situation. Since I have no idea whats wrong I can't help much but have you tried testing the cpu or switching it out to see if that is the cause? Anyways if you find anything else reply and I'll try and help as much as possible.

I have reseated the CPU yes, I don't have another CPU I can switch it out for though I'm afraid. Although if it was the CPU would I not have problems all the time and not just while I attempt to run a game?

I was literally looking up my PSU as I saw your reply to see if it could potentially be a power issue. The PSU is an Arctic Power 700W, it's 6 years old but seems like it should do the job fine unless I'm missing something?

Edit: Forgot my computer specs.
Asus P8Z68-V GEN3 Intel Z68 Motherboard
Intel Core i7-2700K 3.50GHz (Sandybridge) Processor
Corsair Vengeance Blue 16GB (4x4GB) DDR3 Memory (Only running 12GB due to a faulty stick of RAM)
KFA2 GTX 670 EX OC 2GB GDDR5 Graphics Card
Corsair Force Series 3 60GB 2.5" SATA 6Gb/s Solid State Drive
1TB Samsung Storage Drive

You have a nice setup there. Very similar to my own. Can be quite power hungry. Don't supose you have another GPU you can stress test? Maybe even try benchmarking your current card with top end settings to see how it handles?

I dont have another GPU, as I mentioned this card is brand new from the manufacturer 2 days ago and after testing my old one they found no fault. The problem lies elsewhere...

I can't run benchmark as when it gets to testing 3D graphics in full screen it freezes like it does when I attempt to run a game.

As you say it's a new GPU so likely not the root cause, especially if it's been changed already.

The PSU could be the problem if it can't supply enough power.
Might be an issue within your OS or Hard drive.
Case well ventilated and no dust causing overheat?
Drivers up to date?

Have you tried looking in the logs after a crash to see what errors you are getting?

- Start -> Run -> search for eventvwr
- Windows log -> System.

Browse the logs at the time of the crash and see if it managed to find anything.

Drivers all up to date, case is well ventilated and plenty cool enough, it barely gets over 30C in there according to sensors. I have reformatted recently and checked my hard drives with a few programs, all say they are fine.
I am starting to think it could be my power supply not being able to produce enough juice when the computer needs it for running a game. I don't know enough about them to confirm this though, tempted to just buy one and try it anyway. Thoughts?

What you really don't need is this lol.

Again did you check the logs for errors after a crash to see if there is anything obvious?

Before buying anything new. You can always try using software like: http://www.cpuid.com/softwares/hwmonitor.html

Install it, make sure the numbers you are seeing are what your PSU should be outputting and use it to monitor your Voltages whilst a game is going in the background. If it starts to go a bit wild and the game crashes the machine, there is a good chance it is the PSU. If you do go the root of a new PSU. A solid branded 700w will do the trick! I myself run a 750w Corsair with my Watercooled SLI setup with no problems

From my own personal Experience I can't see anything in those numbers that should cause a crash.
Were not looking at a driver lock up here are we?
Have you tried completely removing the drivers restarting the machine and doing a re-install?
Good idea to download the latest drivers first and have them ready to be installed, before you remove the current ones.

This is a good tool for removing Nvidia drivers.

I reformatted recently so that would have wiped all the old drivers. In trying to get that screenshot during a crash today my PC struggled to boot up a couple of times afterwards and kept shutting itself off, leads me to believe more and more that it's a power issue...

I'm going to buy a new power supply and give that a go, I'll keep the thread bookmarked and post if I have anymore problems, thanks for all your help so far.

No problem at all, the final option on my list was to go for a PSU replacement. But just wanted to avoid spending money if we didnt have too :)

Keep us posted!
