Thermaltake "Berlin" 630W and Gigabyte GTX750Ti problem!

[gyakos89]

Hey guys!

I have a little problem with my new configuration: CPU: i7 3770, VGA: Gigabyte GTX750Ti, MB: Gigabyte GA-B75M-D3H, PSU: Thermaltake Berlin 630W, RAM: 8 GB + 1 TB HDD. Yesterday I while I installed the nVidia driver the PC restarted. Then I was able to install the driver, but when i played NFS Rivals for ~5 min the PC restarted again. I tried a stresstest with AIDA64, after 2 sec came the same restart problem... PSU specs: +5V/15A, +3.3V/22A, +12V/45A, -12V/0.3A, +5VSB/3.0A. Plugged connectors: Power (24 pin), ATX (4+4 pin(both)), PCI-E (6 pin), 1 SATA. Please somebody help me out! Thanks!

try downgrading the driver and running AIDA64 again

I downgraded the driver from 337.88 to 335.23, didn't work

ok try looking at temperatures to see if your system is overheating. I quite like using SpeedFan (http://www.almico.com/sfdownload.php). Running FurMark also stresses your GPU and records temps too.

I'm pretty sure that i don't have temperature problems. CPU,GPU is "cold". It's a brand new PC...
Edit: I did ONLY the GPU stresstest with AIDA and it's fine, maybe i need to search the problem somewhere else.

You'd be surprised lol. What settings are you using on NFS anyway?

I replaced a CPU-cooler with a Cooler Master Blizzard T2 and AIDA/FPU stresstest is okay, but playing NFS still causes restart. (Actually, i tried with medium settings).
