My PC I Recently Built Continuesly Freezes For No Apparent Reason

[WalkerGames]

Hello, About 2 months ago I built my first PC with the help of an expert and up until 2 weeks ago, I have had no problems. Recently It will freeze or crash randomly with absolutely no warning. I let it slide for a bit, thinking it was a "phase". Today however, it did it at least 12 times in short intervals. When this happens, the screen stays on what I was last looking at and I am unable to do anything except restart my PC. My friends father who helped me build my rig said I might have to update my drivers so I updated my ASRock z97 Extreme 4 motherboard and my r9 270x GPU. The same thing kept happening. He also said it might be google chrome, since most of the time it crashed on there. I used Internet Explorer and it was good for an hour or so then crashed. Then I tried steam and it crashed on steam. I just need any advice possible to stop this cause it is a big nuisance.

with hard lock ups can be heat or power or a bad part. make sure the motherboard bios is upo to date to rule out a bios bug. in the bios make sure the biso is set to standard speed if it set to performace mode the cpu to ram timing may be off. make sure in the bios xmp profile for the ram is on and the right profile is selected. use cpu-z make sure the ram speed in windows is right and the right ram size is shown. from a boot disk or usb stick run memtest86 overnight see if a ram stick has gone bad. before you run the system overnight check in the bios temp screen make sure with the pc sitting the cpu staying cool. if it getting to 50 or higher in the bios the cpu fan may not be on right. wit hthe pc off make sure the fan on tight and with the pc on check that the cpu and gpu fan are moving. in the bios and using 3 party tools like hardware monitor make sure the power supply 3.3 5v and 12v are withing atx spec. cheep or weak power supply can cause lock ups. use hdtune and hard drive vendor test tools to check for hard drive issues. a hard drive with a bad controller can lock up a rig.

My CPU temperature is at 30 degrees Celsius average. My bois are also updated. I updated them when I did all the updates to my motherboard. The last time it crashed which was 5 minutes ago happened as soon as a signed into steam if that helps at all. It can happen in the middle of watching a video, browsing google, sitting on the desktop. It has no boundaries

Without getting into too much detail, and before going through an organized checklist, I would recommend you remove the graphics card from the motherboard altogether, plug your screen directly into one of the onboard video ports and see how the computer functions. Although motherboard and CPU faults can happen they are not as common as graphics card issues.

Also please be sure to shutdown your PC and UNPLUG it from the outlet before removing internal components. Likewise discharge any static electricity from yourself before touching the mainboard or it's connected components.
