Hi,

I've recently purchased a new graphics card (Radeon R9 270X) to replace my old one (Radeon HD 5850) in anticipation for new games which are coming out. But after installing the new graphics card my PC now turns off randomly. At first it was fine, I was playing new games without a problem and seeing my FPS boost but then it restarted when I was watching twitch. I then went and downloaded Display Driver Uninstaller removed all the GFX drivers in safe mode rebooted and installed the R9 270x ones. Works fine for a little time and then turns off again. This time I reseat the graphics and check the power connectors and they all seem to be connected fine. It happens again but within a shorter amount of time. After reading some threads a lot of people were suggesting to flash the BIOS with a newer version. I did this and rebooted and it reset my CMOS and Windows 8 threw up an inaccessible boot drive because I had installed windows on IDE mode rather than AHCI mode. So i keep it in IDE mode and it boots up but now it turns off after I get to the desktop.

What should I do next?

As far as I could tell all temperatures were normal idling at around 27 degrees and pushing up to 40 degrees when I did actually manage to get in some games.

CPU - I5 750
RAM - G.Skill 8GB
Mobo - Gigabyte - GA - P55A - UD3 rev 1.0
PSU - Corsair TX750 Ver 1
GFX OLD - Radeon 5850
GFX NEW - Radeon R9 270x

All I want to do is play games ;(

If you already have the ATI drivers installed, use the Catalyst Uninstall Manager to remove all of the ATI video driver components



• Download the latest version of the Catalyst Software Suite from Support & Drivers .
• Double click on the downloaded executable file
• The installation will first stop at a screen which notes where the installation folder is. Make a note where this folder is located as you'll use it later on to install the drivers. Then click on Next/Install to continue with the installation.
• The installer will extract the files to that folder and then launches the AMD Catalyst Install Manager. Click on "Cancel", then click on "Yes" to exit the AMD Catalyst Install Manager.
• In Device Manager, click on the sign next to Display adapters.
• Right click on the display adapter and select "Update Driver Software".
• Select "Browse my computer for driver software. Locate and install driver software manually."
• Type or paste the location of the installation folder that you remembered from Step 3 into the search box and ensure that "Include subfolders" is checked - then click on "Next" in the lower right corner.
• Drivers will install. System will then show a window that states "Windows has successfully updated your driver software" Click on "Close" in the lower right corner of the window.
• And you're done!!! Restart your computer for changes to take effect. You will not have the ATI CCC, but your card will work properly. Also, install your latest chipset drivers. Happy gaming!

Lately quite a few people have been ambiguous in this way so please please clarify.

When you say "turns off" does the system physically power off (all lights and fans off)
or does it just black screen?

I will tomorrow when I go to a friends house. The PSU is http://www.corsair.com/en/tx750w. It is about 3.5 years old since i bought it.

The system physically powers off.

As an update. I managed to get into Windows for a couple of hours after getting the AHCI driver installed which seemed to be causing the PC to restart as soon as I got to the desktop. During this time I watched a couple of videos and played some games and got a log from GPU-Z of the sensors. As it hadn't restarted for a while I closed the log and just started browsing the internet when it randomly powered off again.

Ok then the power supply is suspicious if it actually powers off

I tried this yesterday and it was the same thing. It worked fine for a couple of hours then turned off when I was browsing the internet.

I'm not too familiar with PSU knowledge but when I bought it 3.5 years ago I was under the impression it would be future proofed. http://. The PSU has 4 PCI-e connectors so am I correct in thinking that any 2 will work? The only thing my PSU is powering is the CPU/Mobo/SSD/DVD-Drive but I did want to add another SSD drive sometime soon.

After this happened I downloaded memtest and ran it overnight and when I woke up this morning the computer hadn't turned off and there were no errors found after 8 hours of running and multiple passes. I will be going round to a friends tonight and will try the gfx card in his computer. Thanks for the help so far guys.

Hi guys,

I have managed to fix my problem but I don't understand how I have fixed it and maybe someone can shed some light on it.

I had noticed my graphics card has two performance levels according to Speccy and CPU-Z and these are 350/150MHz and 1080/1400MHz. So I was running GPU-Z when it was idle and the clocks were set at 350/150MHz. The computer ran for a couple of hours without a hickup. So I decided to do a stress test with Furmark and ran it for 30 minutes and it was fine with no problem but then I started to watch Twitch and noticed the clocks on the graphics started flickering between 350/150 to 450/1400. These pictures might help explain things. http://imgur.com/a/5129o#0

So I thought there might be a program from the GPU vendor where I could change the performance levels and this lead me to installing the MSI Gaming App and the drivers on the disk that came with the graphics card rather than the latest updated ones, after rebooting, my GPU clocks were set at 450/1400 rather than one of the two levels and I haven't had a problem with my computer shutting down since.

Can someone explain this to me or was it just completely coincidental?
