Hi there,
I need some help with my day i was surfing the net and the screen went blank. I turn It back on and it shows no signal on the monitor. I figured maybe the video card died so i tested it on my dads comp (the one i'm on now) and it worked fine. So then i tried the monitor on my dad's and it also worked fine. So then i figured it was my celeron or motherboard. So i took it to CompUSA to check the prob. They said the mother board and processor burnt out and the video card might be screwed (although i knew the video card was fine). So i go ahead and buy an athlon 650mhz processor and a new motherboard. Install it in my comp and i get the same damn problem still. So i don't know what to do. I'm thinking maybe the power supply is screwed somehow. Although it seems to power everything such as fans and hd's

Anyone got any ideas on what the problem is and what i should do to fix it?

You did try a new video cable, right? Especially if you just plugged the monitor into your dads cable. That would be my best guess since you were just surfing and had not just changed or added hardware. Cables do go bad and more often than not, thought about last. The only other thing I would blame, would be an Amptron or Elpina motherboard.

Here is a thought, your old motherboard was screwed.

Your new motherboard will not provide video signal if the CPU and RAM settings (jumpers) are incorrect. Most people get the CPU jumpers fine, but some mainboards have ram jumpers for voltage settings. Try different settings if they are available and check the mainboards website to see if they have a more thourough documenting of the jumpers. Some mainboards come only with a slim downed manual.

If your speaker is hooked up correctly, and you are getting NO post beeps, then you probrably have an incorrectly configured board. If the lights on the keyboard or system case blink when you throw the switch, then I would say almost for sure you have a configuration problem. If they do not flicker when you attempt to power up, then you probrably have another dead board OR your powersupply is bad.
