Computer randomly freezes even after a rebuild and I can't figure out what it is.

Hey everyone,

So I'm really stuck with this issue of my computer randomly freezing on me for no apparent reason. My computer was about 7 years old (homebuilt) when the graphics driver started to crap out on me, so I decided it was time to go ahead an rebuild the tower.

Before the rebuild, I started getting random freezing for no reason, and it would be at times when I wasn't even at the computer. I would be doing mundane tasks and it would freeze, or I would start the computer, it would boot up to Windows, then freeze.

Here's everything I upgraded:


  • Mobo
    Memory
    CPU
    GPU
    Fans
    Tower

The only things left that I didn't replace are the PSU and HDD. Currently I have a Corsair 550W PSU and a Seagate 500GB HDD. I ran a HDD check and it came back fine, but it's either that or the PSU, but I'm really stumped. I even upgraded Windows from 8.1 to 10, and it's still freezing randomly with no errors.

I'm leaning towards it being the PSU, but I wanted to get some second opinions on how I can go about testing this out before I drop some cash for a new one. Is there a way to test to see if the PSU is failing? Or could it possibly be the HDD?

Thanks for the help!

Your PSU is likely a VS or CS series which are lower quality units and yours is 7 years old from what you're saying. I'm curious why you would not replace it when you upgraded. It should be the first thing on your list to replace unless it's a very high end model. I'm guessing you didn't know the PSU is the most important component in your system. Respond with your budget and where you live or intend to buy from and a recommendation can be made for you. Also give details on brand and model numbers of the rest of your system so that a proper power range can be calculated.

Yeah, I figured it's probably the PSU starting to fail, so I'm going to upgrade it and see if that is it. Everything else is brand new and shouldn't have any problems, but then again you never know. I'll post back with an update once I test out a new PSU. Thanks for the help!
