Just finished putting a new computer together last week and all has been fine till this afternoon. Started it up got the mobo boot screen and thats as far as it will go. can't get into bios to check things, it will not do anything. Here's my setup. ASUS P4S8X-MX Mobo, Celeron D 3.06 gig Processor, 1 Gig DDR , ATI 9550 AGP Card, Maxtor Diamond Max Plus 120 gig HD. Lite-On dual layer DVD Burner,Aspire XQ Pack Case w/420 watt power supply. Everything is at stock settings no overclocking. It will just not run. I could use any and all suggestions. Tried unplugging all cords and cards to see if there was a loose connection but nothing.
