It would be awkward to ask to re-test the PSU especially if the PSU we tested isn't available, opening another PSU won't please him much and I doubt he'd agree to do that.
Sweeper101, so you're sure that it's the PSU?
For someone that went to a computer shop.. bought parts and had them put it together..
a) I would expect it to work 100% with no problems
b) If there was a problem I would expect the computer shop to fix it for free or replace it or give my money back.
If you are not comfortable enough to build your own computer I would not be trying to troubleshoot it.
This really sucks for you and I would be pissed.
You mentioned that your computer micro freezes in windows.. (example.. the mouse freezes for a second while in the middle of moving it from point A to point B. this is not just happening in games....
this is not normal.. don't let anyone tell you that this is common for a computer that is running correctly.
You have done the following:
1) Re installed Windows
2) Updated All Drivers
= This tells me its not software....
you have also restored to the default BIOS config...
its gotta be hardware then... get your money back and go to a different shop.
