Don't want to ruin another PSU, need help trying to find what ruined my last one

A few months ago, I turn woke my pc up from sleep mode and for some reason the PSU surged and tripped my circuit breaker, effectively ruining the PSU. Luckily it was a Seasonic, so I was able to just RMA and get a new one. I'm still not sure what caused the PSU to do that, but I remember I was having problems with my Netgear Wireless USB adapter. It would spontaneously stop functioning completely and it wouldn't pick up any nearby wifi networks. Even unplugging it and plugging it back in wouldn't affect it. I also tried returning it and getting a new one, but had the same issue. The adapter problem happened the day my PSU fried so I can't help thinking that the two are somehow related. Basically after the adapter stopped working I got fed up with it and just walked away from my computer. It was when I came back and woke it up from sleep mode that the circuit tripping happened. Any suggestions on how to handle this? Could there be any relation between the adapter and the PSU? Thanks!

Okay, if you had the PSU 'fry' then your computer as a whole got damaged as well. Most likely your Memory is toasted, but potentially the CPU as well as the Mobo chips (the I/O etc.) also could be permanently damaged. ALWAYS ALWAYS ALWAYS have a solid powerstrip for your 'expensive' powered devices, it is best to have a Surge AND Dip strip (commonly a UPS) as either can damage a system overtime.

IMHO, considering a the extreme low cost of a PC (i3 laptop can be had at Walmart for only $249 for example) PC are now disposable, and basically if you had a power problem with one, it would be too 'costly' to try and replace each single item in the PC seperately (if it is a desktop, laptops you can't replace parts except memory) when compared to the low cost of a new PC (as noted).

Maybe "fry" is not correct terminology for me to use. It surged and would not work any more. Anyways, I built the PC maybe 5 months ago and it came to around $900 in the end. After the PSU died and I received a new one, I tested all the components and they are still functioning and my PC seems to be as good as new now. Boots up fine and everything. It's been suggested to me that it was probably the adapter behaving incorrectly that did the PSU in, so I just want to see if there is some sort of relation between the two. Basically I need internet connection and want to use this adapter, but it hasn't worked correctly from the beginning and I want to know why and if ultimately, it caused some sort of power issue which destroyed the old PSU.

Okay look, there is no "PSU go boom Wireless Adapters will never" direct wire answer NO. IF the original adapter was 'broken' then getting a new one would resolve the issue. While there is MANY reasons ANY adapter may not work at all (Malware, Virus, Windows is hosed, the USB port pins are broken or....) a PSU powers everything, so when it went, as I said, it causes more then just the PSU to fail potentially (I/O ports are damaged, the USB chips are damaged, the RAM is faulty / inconsistent, etc. etc. etc.)

Now that said, let's try the 'basics' to rule out a few things that just happen at the sametime (again just because A happens doesn't mean B does).

Did you install all Windows Updates? Including options except BING? Check them and repeat till ALL are installed.
Download and run Slim Drivers, install all the latest updates but you don't need to reboot until you do the last update
Remove whatever AV your using and go to www.filehippo.com and download AVAST! or AVG and do a full system scan - this repeatedly has resolved alot of people issue relying on MS Essentials.
Download Malwarebytes do a full system scan (AV doesn't pick up alot of malware) - this resolved almost ALL posts to date as most had Malware the AV didn't pick up.
Repeat the AV/Malware scans till the system comes up clean.

Download and run SPECCY, copy and paste the first tab to show your idle temps

To test your system RELIABILITY the best tools are to run HDTune to check the HDD,
then run Mem86x for the RAM,
then run FURMARK and see what it shows for your system as well.

Sounds like a plan. I'll run that tonight when I get home and update with my results.
