I've got to push the power button multiple times for my computer to start up. Usually I just mash it furiously for about 10 seconds, and it'll eventually power up. No other problems. In one of my less impatient moods, it seemed like the lights / fans would come on VERY BRIEFLY after I hit the button, then immediately go out. When I finally got it to power on, I had to hit the power button a second time right after that brief interval -- like sending a second shock to the system or something. Any ideas? My first thought was "bad power supply", but I replaced it -- and I STILL get the same problem. All that's left to replace is the case or the motherboard. Both parts that are a bit more expensive (and a hassle) to deal with. I have an Epox 9NPA+ Ultra, Geforce 7600 GS, AMD 3700+, 2x1GB PC3200 DDR, WD 250GB, SLK3000B Mid-Tower Case -- and I've used a Fortran 450W (worked for a year, then had this problem). Recently replaced it with an UltraV Series 500W (a outpost.com free-after-rebate deal recently). Thanks in advance for any comments!
