Hi, I've just bought a new system that I'm having issues with, and before I return the SP35P2 I want to make sure the right part is at fault. When the issues started the system would turn on but not boot (blank screen), taking out one of the RAM sticks helped so I assumed at first that it was a bad RAM stick. I reset the CMOS and the system booted fine with both RAM sticks in. I set windows installing and came back after about 2 hours, selected the locale and keyboard and clicked next, it looked like the setup was continuing and then the system shut off. And I could not turn it back on. If I leave it off for a while and unplug he power, then plug the power back in the system spins up for a second or two and then shuts off. The system will then not switch back on. Power is still going to the motherboard as when I press the Speed Link button the light next to it lights up. My assumption is the the Shuttle is the problem, but I wanted to see what others thought before I send the wrong part back. It could be another part or maybe I just have too much for the Shuttle to handle. I'm also slightly concerned that the shuttle might have been a return, the protective sheet on the front looks like it has been off before and also it has only a quick install guide and no manual with it (or is that normal). Also when installing the CPU (I've never installed a core 2 before so this could be normal) the protector cover does not sit fully flat, I have to push down quite hard with the clip. The parts of my system are: 1x Shuttle SP35P2 Pro 1x Intel Core 2 Quad Q6600 Energy Efficient 95W edition Socket 775 (2.40GHz) G0 Stepping L2 8MB Cache OEM Processor 1x Corsair 4GB Kit (2x2GB) DDR2 800MHz/PC2-6400 XMS2 Memory Non-ECC Unbuffered CL5(5-5-5-18) 1x Seagate Barracuda 250Gb SATA Drive 1x HP DVD640i SATA 1x BFG Tech 8800 GTS OC 320Mb Can anyone give me any advice? Thanks, Gushy.
