Greetz to all. My computer is not starting and im not sure what the reason is. It first started as a complete inability to power up, hiting the power button the computer didnt respond at all. I suspected the power unit so i bought a new one (550W as i have a shitload of HD-s and CD/DVDs inside) and replaced it. Now i get some response from the unit as the computer starts up for a short time (3-4 sec) bud then powers down again. All the fans start up normaly (CPU fan, Casing fan, PU fan) and all looks normal but just wont stay on. P.S. I get a very silent buzzing noise from the mainboard(i think). When i put my ear inside the comp i hear the buzzing but barely. Its kind of an ambulance melody (Tiii Naaa) but in a buzzing sound. I removed all unneeded hardware (LAN/WLAN/Sound card), inserted another graphics card, inserted another ram module into a unused memory slot, and disconnected all HD/CD/DVD except the boot HD(tried another HD also), so im guessing its none of the above. Any ideas what it could be, and what i can do to fix it? Thx in advance. :wave:
I am sorry to say it sounds like you motherboard went bad... can you give us the make and model of this PC....
disconnect your power switch and short the two pins power switch pins on the motherboard control panel. see if the system stays powered. doing this will rule out the power switch.
also check th inside of the power supply too it may be burned due to a short circuit and check the hardwares too one of them maybe a near death of a hardware
if it beeps like beep beep beep...then wait for few seconds.. then again beep beep beep then something wrong with the memory card.. try removing and plugin it again to begin with
