This is interesting.
I've had my computer for, eesh, has to be atleast a month(edit: OR 3). When I first got it(after putting it together) I threw software at it that demanded none-less than 1,000mhz or more.
While playing the routine round oy Mortal Kombat 2 through a port of MAME called, "Smooth MAME", my computer decided to shut off and refuse to turn back on. This software HAS been used before, and MAME has unthrottled Mortal Kombat 2 on my computer up to 381 frames per second. The motherboard is an Asus A78NX, the cd rom is some generic cd writer. The CPU is AMD 2000+. The ram is 512mb pc2100 DDR. The hard drive is Western Digital 40gb. The video card is GeForce 4 MMX 440. I did not have a case fan intsalled into the tower yet, but a highskilled friend said that I probably could get by without one. I'm only running 1 hard drive, 1 cd rom, 1 floppy, and 1 mobo off that 300w PSU. I have 2 free IDE power plugs. Could it be the Power Supply? I've stress-tested the AMD chip countless times and like I said, I'm using the 2000+ and I have a heatsink and fan recommended by AMD(or from AMD, not sure, has their sticker on it) that is designed for the 2800+. I'm not stressing the PSU, the CPU has adequete cooling.........I-dunno, any ideas?
