How's it going guys.

Well to start things off, new built computer running just fine for a month. I decided to get greedy and put my 42' westinghouse tv as my monitor. As soon as I did that, about 15 minutes later my computer just shut down and went into boot loop.

I took it to Microcenter and they had no problems with the computer running, I took my computer back to my house and tried it on another monitor and it worked fine.

At this point I was thinking that it was the Westinghouse TV(I'm a newb with computers)

But then I took my TV home and tried it with the computer and it worked just fine.

I recently tried to take my computer back to school and the computer started up and said "Power Surge on Hub Port" or "USB device has exceeded the power limits of it's hub port"

My computer shut down right after that and would not start up.

I took my new computer back to my house and it worked just fine.

So then I took my older computer, with the same powersupply voltage to my dorm and it worked.

-Computer doesnt work at dorm, but works at home
-Only had this problem after trying to plug in my TV as my computer

Thanks guys, hopefully you don't strain your eyes reading that!

It's a warranty issue.

It may require the maker visit the site where it fails but the only thing missing is the exact PSU in use. Let's hope it's big and has a single 12V RAIL.

BIOS Issue

Thanks RProffitt
ATM I'm trying to find the post about the BIOS issue.

If it means anything I have a 600W Power Supply (12V)

Good number of Watts but how many rails?

It would have been nice to read a make and model number. Then I could check if it's a possible issue.

Given it's not a single rail model, did you try the video card on the other rail?

Switching rail

I will try this when I return home, Thanks for all of the input.

Another fact that I forgot to mention, I was having boot loop problems around the time this all started (Only at dorms). I havent updated my bios either. (Current Bios is from September)

I didn't check the BIOS versions.

Sometimes it helps to read the changes. I've lost track of how many are buggy. And forgot one thing.

Did you try it with more ports disabled? Some BIOS allow you to disable onboard ports or this port or that port.

Might help?

My other computer is working perfectly fine at my dorm.

I just had my newer PC at my brothers house and we flashed it to the new bios and everything was just fine.

Now I can't even get the newer PC to power on at the dorm. :[. I swapped power cables and tried every outlet.

Sounds like a warranty issue to me.
