my mobo is a MSI k8n Neo4 my video card is a Nvidia 7900 GS my power supply is an Apevia 680w Beast Power about 3 months ago my computer started to get hard to turn on, it would do the normal beeps and stuff but then get stuck at the windows xp loading screen, and I would have to restart it like 5-7 times to get it to acually load up past that screen. after a few weeks of that it stoped giving me a beep all together. Everytime I tried to start it, it would just sit there, the fans would run, the cool cathode lighting would run, the video card ran, the HDs were spinning, the power supply lights up, but theres no beep signal and no video response. Im pretty sure nothing is loose in my system. I unplugged everything pretty much and just had my powersupply, cpu, and mobo connected, but still no beep signal. I saw a post where someone suggested to unplug the cmos battery for 15secs, I did that but still nothing.
