I recently got an Edge Z40 from Velocity Micro with the following components: PSU 700 Watt Velocity Micro® Power Supply Motherboard Asus® P8Z77-V LK Intel® Z77 based chipset, ATX Motherboard Processor Intel® Corei5-2500K processor, quad 3.30GHz cores, Hyperclocked to 4.0GHz RAM 8GB DDR3-1600 Dual Channel Memory (4x2GB) Graphics 1GB eVGANVIDIA® GTX650 GDDR5 video card (GeForce GTX 600 series) HDD 1TB 7200rpm SATA 300 w/NCQ At first I thought there was something wrong with it because my monitor did not detect it, but that was in fact because I had connected the monitor to the motherboard rather than the graphics card. Now, after a few days of normal usage (no problems or noises whatsoever), it will not boot. Turned on my surge protector and then the computer one morning and the LEDs inside the case light up and the computer immediately started making a high-pitched sound that I can only describe as the squeal a balloon makes when you stretch the neck and let air out. After a few seconds the computer shut down and stopped trying to boot. After that I think I pressed the power button a few times and the computer tried a few times, unsuccessfully, to boot, behaving the same way, but for shorter and shorter lengths of time. i.e. it would squeak less, and stop booting much more quickly. Now each time I try to turn it on, it squeaks for only a fraction of a second before stopping. To try and diagnose the problem, I took the hard drive out of the case, and verified that the sound was not coming from there. I removed and turned all the fans to make sure there was nothing blocking them, or forcing them to squeak, all the capacitors on the mobo look fine, and nothing smells burnt. My main suspect is the power supply, since one time that I tried turning it on, I immediately turned of the surge protector and then rocker on the PSU and then unplugged the power supply for good measure, and the squeaking continued for a second or two afterwards. Thank you for any help you can provide in resolving this issue!
