Random BSoDs, mostly while playing games

So this PC that I started using recently has a problem with BSoDs with random driver/error codes that mostly happen while playing, but sometimes also while browsing the internet(maybe with youtube on). I can't replicate them in any way and they happen after around 30-60 minutes of playing a game, though sometimes faster.

I don't think it's a bad driver because I remember this happening pretty much always since this PC was built, on different OS with different sets of drivers.
I have no idea how to recognize if it's a PSU problem, but the PSU is probably a cheap one.

EDIT: I logged temperatures before the crash happened, it's definitely not overheating.

Hi mancowed.

Your latest BSOD is caused by Wi-Fi Wireless LAN USB Adapter (c:\windows\system32\drivers\athrxusb.sys).

Code:

BugCheck 50, {ffffaa8800573666, 0, fffff8800523e4cb, 7}

*** WARNING: Unable to verify timestamp for athrxusb.sys
*** ERROR: Module load completed but symbols could not be loaded for athrxusb.sys

Could not read faulting driver name
Probably caused by : athrxusb.sys ( athrxusb+3e4cb )

Followup: MachineOwner

And the driver is extremely old.

Code:

fffff880`05200000 fffff880`05291000   athrxusb T (no symbols)           
    Loaded symbol image file: athrxusb.sys

If possible, update the driver. Also plan to update the BIOS and chipset drivers. I am not very aware of MSI downloads, so failing to supply you the download links, but your motherboard is G31M3(MS-7528), the BIOS version is

Code:

BiosVersion = V3.5
BiosReleaseDate = 03/12/2009

Daemon Tools, Alcohol 120% and Power Archiver Pro uses SCSI Pass Through Direct (SPTD), which is a well known BSOD causer. Uninstall Daemon Tools at first. Then download SPTD standalone installer from Disk-Tools.com, and execute the downloaded file as guided below :

• Double click to open it.
• Click this button only:
• 
• If it is grayed out, as in the picture, there is no more SPTD in your system, and you just close the window.

Let us know the results.
