I live in a rented house and it's electrical wiring doesn't have a ground line. I'm using 3-pin plugs with 2-pin converter. I have desktop computers, laptops, wireless routers, network switches etc all plugged into this ungrounded line. Touching any metal parts on this devices proves the current on their body. I didn't measure the current using meter but electrical testers always shows off. Can this ungrounded line cause damage to the electronic devices I mentioned?

Can it cause damage? Probably not. However, it could definitely harm/kill you if even the slightest thing goes wrong. Especially if you can feel any tingling when touching them.

Use of devices that requires a ground (not double insulated) without one is illegal in most places.

Actually it feels a strong tingling when touching them. My landlord won't fix the wiring anytime soon. What can I do as an alternative?

If you can actually feel it, he is required by law to fix it. "won't fix it" is not an option.
(assuming you are in the US)

Unfortunately that's not the case. I live in Dhaka, Bangladesh. You probably never heard of it. Law here doesn't go that straight :(

If you have metal pipes you can run a wire from the pipes to the ground plug on the adapter. You have to make sure the pipes are actually grounded if you try this. Another way would be to get a piece of steel (rebar) and pound it into the ground. Then run a wire from the steel to your ground plug. You could test it with a multi-meter.

Also, you should short NEUTRAL (Not phase. Don't use phase. If you use the phase/live/active wire, there will be sparks) wire to ground. This should really be done in the switchboard, but it's better than none. This is just tissue paper over the cracks unless you use a proper earth rod, though.

Rebar into the ground is essentially the right way to do it. Threaded steel rod is the easier way, as you can just put two nuts on the top and put a lug between them.

Wow!! Didn't know something like that can work. I'll definitely try it. Thanks :)
