PSU: Xclio "Goodpower" 500W LED Indicator Light Key: Orange = Stand by / Green = Power ON Yesterday, my computer emitted a semi-loud *crack* in the area of the main power connector when I tried to restart it when the motherboard was directly connected to the computer case (I was stupid and didn't install the standoffs), then died (no smoke came out). When I try to reboot, every fan in the computer would begin to spin, then immediately die out a second later (fans don't halt to a stop at once, they just spin until their momentum is spent). The LED indicator lights on the back of the PSU would light orange on the initial plug in of the power cord, then would flash green then go back to orange in relation to the fans powering up when I press the power button of the computer. Also, after I press the power button the first time, the power button will not work again until I remove the power cord, then reconnect it to the PSU after the LED goes out. Also, there is no burning smell in the PSU. Is my PSU in working condition? Extra questions (somewhat off topic): 1) Can a fried motherboard fry its connected components? 2) If the fan of an 8600GT graphics card is working, does it mean that the graphics card is fine? 3) Is it an ABSOLUTE MUST to remove/reapply thermal paste every time you break the seal?
