Computer boots but nothing shows.

[Craig56]

When i try to boot up my computer, nothing shows up on my screen. All the fans spin but, when i start it, the red light for hard drive activity stays on but there is no activity, and i hear, beeeeep beep beep. I did nothing that i know of to cause this. I receded my memory and lan card but nothing is back. i booted it about a dozen times and still have the same problem. it worked 5 minutes ago before i shut it down, i didnt intall anything. PLEASE HELP ME it will be greatly appreciated, greatly.

My motherboard is, ECS K7SEM v1.0
My processor is AMD DURON 700mhz
and my ram is 320mb samsung (one 256mb and one 64mb sticks)
Integrated Video and Sound, SiS chips.

well it sounds like something has failed. (duh, right...)

In my experience, booting without video is often caused by bad memory or a bad memory setting. You system is quite old so I wouldn't doubt it if your CMOS battery has died and fuxored all your mem timings.

These are the things that I would check out in order
-Reset CMOS
-Try to boot with one stick of mem (check your MoBo manual for mem configuration info)
-Remove all optical drives and unnecessary PCI cards from system and try to boot
-If it boots, it may not be the hardware but instead a weak PS
-Swap out PS

Also, with that beep code, find your manual and figure out what your system is saying to you.

Good luck
