On boot , no beeps, no signal to monitor. Tried monitor on other PC=> OK, ----- Video Card on other PC => OK, ----- Power supply on other PC => OK, ----- Ram on other PC => OK, Reset CMOS => boot failure. After a couple days, PC boots. Upgrade bios, every thing is fine for a couple of weeks. Then will not boot again, after a couple days, it starts all over again.!!!!!!! - Motherboard: EPOX KT-133M - CPU: AMD Duron 800 - RAM: 2566mb - Video Card: ASUS GeForce 32mb - OS: XP Any insight would be appreciated. Thanks. ABDCG

you say tried monitor,power supply ect. in different comp> ok but for one hour or 2 weeks? I take it you comp will not turn on again at this time. does all fans turn on? does any led's light up? will the cd drive open?

you say tried monitor,power supply ect. in different comp> ok but for one hour or 2 weeks? answer: one month I take it you comp will not turn on again at this time. does all fans turn on? answer: All fans turn on. does any led's light up? answer: All leds turn on. will the cd drive open? answer: CD drive will open.

Part 2: I changed the power supply(brand new), failed. I am leaning towards the CPU or the motherboard, if only because it does the same thing, when one boots a computer without a CPU.
