I just upgraded my pc, but I only put it into a new case, nothing else. Now when I turn it on, it only lasts for about 10 minutes. When it shuts down it is just instant, no blue screen or any error, it just goes black. Then it will try to reboot but it will shut down while rebooting, then it will try again and start up all the way, only to shut down about 10 minutes later. What should I do?

You should list your components so we know what we're dealing with. It sounds like the PSU to me - just a guess without knowing what you've got.

sure, I have:
i5-2500k
old nVidia GTS 250
ASUS P8z68-v gen3 mobo
WD Cavair Green 500gb HDD
Antec EARTHWATS 500W
Also I should say that I just put it into a case with 10 case fans (up from my original 3 on my old case) And two cold cathodes.
I guess it probably is the PSU, so the question now.. How many Watts do I need?
EDIT: 8gb Corsair Vengeance

Probably the best estimator on the web:

when you use this put in your (someday) GPU upgrade so you'll be ready when and if.

That PSU has 44amps and is more than enough usnless it went bad but I doubt your system would boot. IMO something happened during the transplant.

Case fans are not typically huge power hogs. Lets get your temperatures out of the way first. Use a program like HWMonitor and watch your temperatures for those 10 minutes. Record them and report back.

Next open the case up and make sure everything from the PSU cables, to the sata connectors are firmly and correctly connected.

Also wouldn't hurt to check your windows event log for any helpful information given.

Have you checked to make sure you don't have an overheating problem?

What temperatures in HWMonitor should I be recording?

Everything, as soon as the system boots start HWMonitor. It will give you readings then let it sit and kepp an eye on everything watch the voltage as well.

Now when I turn on my PC, my keyboard and mouse turn on, but my monitor says "no input"

Remove your GPU and try one of your mobo's outputs.

I would highly suggest unplugging every non essential piece and fan and only run your essentials, unplug all unnecessary usb cables but keyboard etc. if it boots let it sit at the windows login / desktop for awhile anbd see if it fails. if not turn it off and plug in an additional component (fans being lastly connected) if a particular component causes the issue, its likely either an issue with that component or a power issue, if you get to the end and start plugging in fans and that causes it to occur, its a power issue (or short somewhere) If that works but connecting usb devices , mouse etc causes it, it could be some sort of usb grounding out the chassis isuse, i've seen it before.

Pay close attention to the motherboard faceplate , and how the motherboard is mounted. make sure you dont have an extra mount where a screw doesn't match on your board etc. Good luck.

But don't unplug your CPU fan. Check for the little tabs on your faceplate going into one of your usb ports (or any port for that matter). That will cause a short.

I started my PC with everything plugged in before you posted that, and now it booted into startup repair saying "your computer was unable to start"

I would still try the above suggestions first. Then repair if necessary.

Well it booted up. I Recorded the temps for both the CPU and GPU over 10 minutes.
GPU:
0:33C
1-10:34C
Basically didnt move at all.
CPU:
0:31C
1-2:29C
3-10:28C

Doesn't look too "hot" to me. How about the short situation?

No tabs seem to be doing damage. if I have cable sleeving touching my mobo, would that short? P.S, comp still running after 26 minutes.

Not unless it's "electrically conductive". Good news about the tabs (that happens a lot). Fingers crossed for you. :)
