hi, I have a problem with my pc, in the sense that when I try to boot I get no signal to the monitor(which, by the way, is a 42" plasma that works on dvd and satellite and sky). for mobo I have a gygabyte sSseries, AMD 4600 dual core processor and 4GB of memory. when connecting the power cable, i get lights on power button led, and just a short blink on HDD led, but the leds for usb and ethernet are ok. sometimes hwen I try to start the pc from the main power button I cannot do it doesn't start at all, so I have to unplug the power cord and re-plug it, and only if keep the power button pressed when connecting the power cord, the pc will start.
I swithced the video cable from my ATI Sapphire 1600 pro to mobo's own graphic adaptor, but still no signal. I have recently installed two more memories(2GB) and that was when it has all started(system didn't want to boot). changed memory slots, removed the new ones, nothing. took out the old ones and left the new ones, it worked, took out the new ones and left the old ones, it worked again. put them all again , it worked again, but I started having problems with shutting down, it didn't want to shut down, so I had to turn it off using the power button. there is a strange beep that comes up every2-3 seconds after the initial long beep(when checking the bios/cmos). what could be the problem? the mobo, the processor, the memory?
Thanks for any advice.
