<human>: Ok, so last night the lights in my bedroom went out. They've been there since I bought my house (first house woo!). All the lights went out too, so I assumed a bulb blew. So I trudged into my cellar and flipped the lights fuse switch. (after I had made sure to turn off the light switch in my bedroom)

When I went back into my bedroom I flipped the light switch (expecting all but one of the bulbs to come back on, but they only came on for a fraction of a second then the lights in the house went out again. After again turning off the light switch and turning the fuse switch back on I tried again only this time nothing happened at all.

I assumed all the bulbs went (there are 4), I went out and bought some replacement bulbs after I had googled the ones I needed. (Apparently MR16 GU5.3, 20W)

After replacing all of the bulbs the same is still occuring, when I flip the light switch nothing happens.

Is it possible the wiring for my bedroom lights are messed up? Is it possible there's a fuse in the light fixture itself that has blown?

One of the bulbs: 

The light fixture itself: 

I'd rather not call out an electrician unless necessary. Last thing I want is to be told I just needed to replace a fuse.

Any ideas?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Light bulbs blew, replacement light bulbs aren't lighting up. I don't know what's wrong. (This is in the UK)
