Hey there, I've got a odd problem with my HTPC on start up. Sometimes when I turn it on it reboots (several times or once, its random) and then boot trough to Windows completely where it has no further problems. I find this extremely strange since the system has not been overclocked. I also recently swapped out the PSU for a better, more reliable one (Antec TP-650W Modulair). The motherboard is a Abit AN-M2HD. It has 4GB of DDR2, 667mhz and a Geforce 9800GTX+ of the brand ASUS. Any help would be greatly appreciated.
