Hi! My PC does not boot but all fans are working(including video card), hard drive makes sound on start up, and so does optical drive. After turning on the PC the Hard drive LED lights up for quite some time. And I do not have to prolong pressing the power button to turn it off. I got an on board and PCI video card. I set on BIOS to use PCI express Video card. Aside from a booting problem I get a blank screen, no signal is received by the display.
The problem started when I replaced the CMOS battery because date and time is not correct. I hold on the power button to turn of the PC because I was in a hurry to get the CMOS battery. I do not have monitor instead I use the DVI port of the video card to connect to the TV.
I shorted the border to return BIOS to default setting and still the same problem. I also removed the RAM to test if it beeps and it did. Before I had the same problem it was because I had a very low PSU. The PSU was not able to run the video card so it used the on board video card and was able to boot. This time however I do not get a boot and no display. The only thing i changed is the CMOS battery.
CPU Athlon 6400 X2
PSU Silverstone 500W 30A 12+
Video Card GeForce 8800 GTX
