ok so these past few weeks my computer has been a bit schizophrenic. it would randomly freeze and reboot while i was on it or when I left it alone. It also recently developed an issue with its audio: unless I turned the volume down to 1 for each individual application in the volume mixer (windows 7), all I heard was static whenever sound was supposed to come out. I figured that it might be a bad power supply; its the only piece of old hardware left in my computer after my recent hardware upgrade. This suspicion was pretty much confirmed when I began to hear the telltale high pitched whine of a failing power supply coming from it. I put off replacing it, however, because I have been very busy, and the computer still functioned. Two days ago, I was trying to get some work done, and that whine was making it difficult to concentrate. I shut down my computer, but the noise didnt go away. if got much quieter and higher pitched, but it was still there. Only when I actually unplugged the computer did the sound go away. I got curious, and went to see if the sound would come back if I just plugged in the computer without turning it on. I plugged it in, and the sound did indeed come back for about a second. then, the power supply's fan started spinning really really fast and making a bunch of terrible noises. when sparks started coming out of the back of it, i unplugged it as fast as I could.
Today I got a new power supply and hooked it up, but the computer wont boot. the fans all turn on, and all my motherboards lights turned on, but I couldn't hear the disc drives or hard drives shuffle like they normally do on boot up, and I wasn't getting any video to my monitor.
Does anyone have any ideas as to how I should go about troubleshooting? I really don't want to have to get a new computer......
