Replaced Case and Now PC Won't Start

Hi,

after fiddling for about 3 hrs with the new case, I'm all out of ideas. I have just bought Thermaltake V4 case and the PC won't start anymore. The moment I plug in the power cable to the PSU and flip the PSU's power switch, it immediately starts up, even if I didn't press the Power switch on the case! All fans are spinning, leds are lit, and after about 3 seconds it dies. No matter how many times I press the power switch on the case, it won't start. I also tried many different combinations with the mbo's system panel connectors (Power switch, reset sw, hdd led, power led, speaker). Also, I read something about maybe having a short-circuit, but I don't know how to fix that. I also tried putting the PC back to my old case and everything works (it didn't get fried, whew). The case has "lumps" on which I screwed the mbo to and it also has one brass (or whatever) pin in the middle (something like a stand-off but with a "pin" instead of a screw-hole). In the old case the mbo was sitting on stand-offs. Is that the problem? I can't put those stand-offs onto the new case because then the whole mbo is lifted up and its back panel won't fit.

I also tried the minimalistic setup (i connected only a cpu, ram, hdd and gpu to the mbo-no fans, external usb connectors...)

I also have Corsair 500W PSU and Asus P8H61Pro mbo.

Thanks in advance!

Or this pin in the middle (not sure exactly what you mean btw) touching the board?

Could you try hooking up the power switch from the old PC to the board in the new case? Alternatively you could try using the reset switch as the power switch and leave reset disconnected.
 
from the sounds of it, its being shorted out and if a standoff or watever ur talking about is touching the board where its not supposed then theres ur problem.
 
It's the case's power switch. I connected my old case's power switch and it works. So I guess I have to return the case to the seller? I bought it new

Thanks again for the helpful advice!
 
I tried using the new case's reset switch in power switch's place and it works. Dont know whether to return the case or not now 😛

Again, thanks again for all your help!
 
Hmm, I thought that even with the "bumps" on that case, that you still had to install standoffs onto the bumps. I could be wrong. It's been a while since I built a rig in that case. As I recall, it was a fairly nice case, for the price, but the LED exhaust fan didn't always spin when I powered the computer on. (Could have been a mobo fan controller fault too, I suppose.)

well if its only the power switch theyre usually replaceable and r relatively cheap.

In the end, I switched power and reset switches on the case, and that worked for me as I almost never use hard reset (and starting up the PC by pressing the reset button is silly) 🙂

Try turning the motherboard connector for the power button around, it may have been wire backward.

I tried that, but it behaved the same way.



Thanks!
