Oh man I am sooooo screwed. Bought this new computer just last year and a few hours ago it went kaput. I don't know what happen. It was making a lot of noise, most notably from the fan, which was a lot louder than before. In fact, it got loud enough for me to try to "fix" it. So I opened it up and cleaned out the dust that I thought was causing the noise. When I re-connected everything and press the power button -- nothing. Not a single thing! I don't know what happened. Maybe the power supply died, which is my only idea. Then it occurred to me -- could me forgetting to switch "off" the power switch before unplugging everything have an impact? I can't remember if I did it or not! I'm thinking I might have forgotten... Anyways, hope you guys can offer some advice. I have a CPUSolutions.com bought PC (from the website): Athlon 64 Socket 939 PCI-express Barebones * ASUS A8V-E-SE ATX MOTHERBOARD * Front Side Bus-2000 MT/s * PCI EXPRESS VIDEO SUPPORT * DUAL-CHANNEL DDR400/333 UP TO 4GB * 2 x Serial ATA RAID * GIGABIT LAN * 8 USB2.0 PORTS * ATHLON 64 3200+ SOCKET 939 * ANTEC SUPER LANBOY ATX TOWER * AGI 350W POWER SUPPLY I put in a new HD and a gig of memory. I should add that when I connect everything and press the power button, there is just nothing. Just nothing at all. This is IMMEDIATELY after I opened the computer to clean it and put it back.
