My computer have been having problems shutting down and restarting and now it will no longer post. When I turn it on the power led comes on and everything powers on but HHD led does not come on and doesn't post. I'm deaf so I can't hear the beeps, sorry.

I tried powering it on with just one stick of ram and dvd drive unplugged. No good. But before that when the computer was still working I ran memtest on each stick of ram and then all sticks of ram together. They all passed the test. Does that mean ram is good in this case?

I even tried taking the computer apart and cleaning and rebuilding it back together again, no good. Is my computer dead?
 
Yes. A drive is not required.

You need:
- motherboard
- video card/chip
- Power Supply
- RAM
- CPU and heatsink/fan
- monitor (just to see things)

That's all you should have hooked together if your problem is this bad. I assume by POST you mean you see nothing on the computer screen at all?

Anyway, this is basic troubleshooting:
1) hook ONLY the minimal parts I listed together
2) Can you see the computer booting up (POST?). If you see NOTHING you need to verify the monitor is working.

3) If the monitor works, but POST still fails it's one of those parts. Basically you'd need to SWAP parts somehow to verify everything works which is a pain.
 


I did try to power the PC with that list. no POST.

Damn it! I don't have much money and I wanted to play Just Cause 2!

Maybe I can borrow some money from my dad and just purchase parts for budget computer if I can't get it to work.
 
It's ONE of those parts which is defective, but as I said you would have to swap parts.

Since you apparently don't get an audio BEEP, I doubt it's your CPU. Your RAM was swapped so it's probably not that. Your monitor likely works.

If your graphics card was defective you would probably still see some nice lights and fans starting up on the PSU/motherboard.

In my mind that leaves:
- motherboard, or
- Power Supply

The easiest thing would be to borrow a power supply (or buy a cheap quality Antec or similar on sale at NCIX for under $40).

Statistically speaking it's probably the motherboard though.
 


Well I plan to update my computer (its 5 years old and is showing its age) but instead of buying all parts first I plan to just order PSU first and test that. If not then I will just update my computer anyway.
