Ok this morning my antec 300 case arrived.
I moved all of my components to my new case fired her up and after about 2.30 minutes (Not exact) it just reboots.
I looked in the windows event viewer and it just says that there was a power failure. So i swapped the PSU into my missus rig but it works flawless, hers in mine again 2.30 minutes-ish it reboots.
Ive tried the usual pushing down of components and checking leads to no avail, Anyone got any ideas?
