I'm kind of new to building computers, but I thought I had it down. I ordered a new motherboard that came with a graphics card and a windows XP install disc. The motherboard is an ATX form factor with a LGA 775 processor socket 4 DDR2 slots, 4 PCI slots, and 3 PCI-Express Slots. Unfortunately, the only other fan I have for a 775 Socket, fits Micro-ATX. I knew I couldn't do anything without a fan, but I figured that I could at least see if it would turn on. It did and after the first four seconds I reached in to turn it off, but then it shut itself off. I tried to turn it on again, but it gave off a series of loud beeps alternating between a high pitch and a slightly lower pitch and shut off again. After I unplug it for about a minute it will run and show the start up screen again but then it just starts over. The processor is a Pentium 4 running at 3.40 GHz, and when I touched the housing it almost blistered my finger. What I wanted to know before I invest in a fan is if it is the cooling that's causing this problem. Like I said I'm relatively new to this. Help please?
