PC randomly freezing

[iCobble]

I'm having trouble running memtest. I've tried using Memtest86 and Memtest86+ by using the autoinstalller for USB, but when I put my USB as first boot priority, my computer just starts up as normal.
The freezing is still happening unfortunately. Just recently my computer kept freezing for a few seconds consistently and my mouse pointer sort of disappeared. I did notice that every time it froze my CPU usage would jump to about 47%.
Hope everyone had a good New Year by the way.

Burn memtest to DVD and try that, some USB sticks are not supported for boot depending on some brands of mboards and sticks I believe, it is the only reason I found off top of google search as to why it wouldn't boot from the priority selection you made.

Happy new years to you aswell!

edit: Also something important for certain sticks/mboards:
Format USB stick with either FAT 16 or FAT32, NTFS is not supported.

Thanks for the advice zeke. In the end the USB somehow worked and I ran Memtest for 3 passes with no errors.
Still no idea what is causing the problem. The freezing is still occurring, and like I mentioned before, now my PC stops responding for a few seconds and CPU usage spikes, before returning to normal. I might make a new thread as I'm not sure whether these are separate issues.

Still haven't fixed it...A couple of times I've restarted my computer to find no boot device is being recognized. I just fiddle around with my SDD cables and it goes away. Could my SDD be the problem? I've used Seatools to scan it and no problem has been found.

Might need new sata cable?

Might need new sata cable?

Thanks, will order one now as they're pretty cheap. Hopefully this will help.

I installed a new Sata 3 cable yesterday to my SDD, and unfortunately it hasn't helped. Computer just froze twice in a row.
This is so frustrating, no idea what's causing it. Any suggestions are much appreciated!
