okay, so basically i've recently built a system to which i've been running for about 4-5 months and now have replaced my motherboard. Now, after putting my system all back together it won't start up, the fans all fire up and the lights are all on but there's nothing on the screen. There are no beeps. There is a red flashing light on my pc tower which i've never had before, it flashes every 1-2 seconds. I've never actually watched a motherboard when it's on so i don't know what is normal or not, but there is a red light that flashes between 2 things that have written below them "CPU" and "DRAM". There is also an amber flashing light behind the graphics card, but i can't see it to see what it says. The only noise i can hear the is out of ordinary is what sounds like a fan powering on and off, though all fans are on and look fine. The sound seems to be synchronized with the light flashing between cpu and dram. the motherboard is ASUS Crosshair IV Formula graphics card: Asus 1GB Radeon HD 5770 ram: 4gb corsair xms3 power supply: coolermaster gx650watt CPU: amd phenom II x 4 any other details needed let me know. hope somebody can help as i have no idea what the problem is! i took a lot of care with the motherboard so i don't believe at the moment i've damaged it. Thanks!
