I have recently built two similar DIY computers both of which are not working!
Both are AMD processors (Athelon 64 bit) one a 4800 and the other a 5000. I have two different cases and each has an antec earthwatts powersupply I have crucial 6400 DDRII 800 1gb memory chips in both (and have also tried super talent 1gb sticks - same issue) Both have SATA HDs and an IDE CDRW - different brands.
The motherboards are different - one is an ECS and the other is a Gigabyte.
Now, the problem:
The fans whirl, the HD spins, the memory LCDs light up. The monitor doesn't seem to get any signal, the keyboard caps lock, etc. keys don't light up and the cdrw when plugged into the motherboard doesn't open/close (although when I keep power on but connector unhooked, it opens/closes). I assume because there is no monitor signal the machine is not booting but I thought building two different systems would compensate for any single part being off.
Start with the basics, pull everything out and work on a NON-STATIC surface (Static Electricity kills components), you should be looking at just the CPU/board, PSU, 1X RAM module and video (unless integrated) obviously connected to a monitor...
This approach will allow you to eliminate/determine any issue related to the primary components, additionally make sure you've cleared your CMOS/BIOS (pulling battery & jumpering pins as per manual), also please ensure you've plugged the heatsink fan into the appropriate motherboard header, as the RPM sensor within the BIOS needs this information to POST.

Is the monitor new? Because some monitors need to warm-up a little bit. Have you tried to remove video card and/or mother board and reinsert? If that doesn't work, try the video card in another PC, If it works there, then the video card
itself is probably not the problem. (recommended). And those beeps (3-3-3-1) mean "Erase F2 prompt", but I don't know exactly what that means. This is all I know for now.
did you replace the PSU power supply unit with a new or a heavy duty one if its struggling with the fans winding you might need more power /grunt also check cmos battery for a secure seating and has plenty of charge/power check leads from motherboard to hard drive make sure all connections are secure i read something about low resistance fuses on your motherboard you might want to check these
check the ammount of ram and compatability If you're not sure if a module is right for your system, use theCrucial Memory Advisor tool for a list of guaranteed compatible modules. hope this helps you
Hi, the thing to do here is to narrow down what could be causing the problem, initial suspects would be the RAM chips. If you have known working ones you can try in it, try these, if not, try without one, then swap them over, or even try without both.
Also, remove any components that aren't strictly necessary, i.e. hard drives & cables, cd-rom/dvd drives, extra PCI cards,network cards etc
Another suspect may be just a loose connection, try taking everything out, re-seating it. Again, pay particular attention to the RAM chips.
It could possibly even be a faulty processor, have you another you could try? Try taking it out and re-seating it.
It sounds to me like the processor that you bought is not fully supported in the current bios in your mobo. I would check the epox website for newer bios. Be careful flashing the bios, if you misstep in the flash, you may end up with a brick. If you are successful, you should be able to run the processor at the speeds you expected, though within the limits of the hardware on the mobo. Also look at the spec's for the mobo on the site to see if your processor is listed as being supported.
some times the drivers in it couse them to shut off and restart. tri to update the video driver. sometimes when you put in a mother board the scew's that dont have a washer can short the computer. try to losein some of them. I hope this will help.
There's a number of possible problems.
A momentary press of the power button will probably not turn the computer off, in this state, but holding it for 4+ seconds usually will.
Did the computer work previously? If so, did something change recently?
Usually, this sort of problem will arise after a hardware change; e.g. installing more RAM, changing something in the BIOS settings, installing a new video card, etc.
If nothing changed (including things you may not have been aware of), and the computer just stopped working, then a part may have failed, possibly due to a power surge or similar.
Depending on your computer knowledge, comfort with working on your computer, and whether there's any warranty in effect, would determine any additional action. Please provide additional details.
