Amazon doesn't repair old Kindles. Also you are out of warranty. However if you ask them about the problem, they might offer you a decent price to buy a refurb of the same or a newer model.
If it is rebooting/hanging repeatedly then it probably isn't just installing firmware (there is a firmware upgrade waiting for my 3G Kindle 3 keyboard model according to the Manage Your Devices page at Amazon)
You could check if it is stuck indexing a book. From the library screen search for a nonsense word like pghtywd and wait. it will take a while buy eventually it will either tell you the word is not found OR will tell you what book it is still indexing. If it is still indexing a book, delete that book.
You could try a soft reset. Turn the Kindle off. Now hold the power button or slider ON for 30 seconds. Let go and wait for the Kindle to totally reboot. Then use it and see if the problem has gone away.
After doing those things, if it still hangs/reboots then your Kindle could be damaged. Did you do any damage like accidentally yanking the charging cable and bending/angling the mini-USB socket?
Are you using one of those trouble-causing cases that clip into the powered slots on the left edge of the Kindle (some of Amazon's cases used that for cases that turned the >Kindle on when the case was opened ot ones that had a built-in light). Many people in the past have had rebooting and lockup problems caused by those kind of cases. I won't use them. I use a case that holds the Kindle in w/ elastic corners and I turn the Kindle on myself. And to deal with lighting, I eventually got a Kindle Paperwhite so I no longer need a separate light to read in the dark.
BTW if you get a new Kindle and register it to the same account, you can send the Kindle books you bought at Amazon to the new device (one at a time, but it works). You can do that from the Cloud tab or Archived Items list on the device or from your Manage Your Kindle page.

大概意思：

亚马逊不会帮你修这么老的kindle了，一般是建议补差价你换购个新的。
你可以：
1、升级固件
2、搜索一个没有意义的单词 比如 wjoasjaosifjas (肯定搜不到），然后结果中会有一些书本显示没有被索引（items not yet indexed），删了这些书
3、重置到出厂设置
4、要不你还是买个新的kindle吧

从上面的文章可以看出，似乎这种间歇性重启和建立索引有关，可以猜测一下，可能是kindle建立索引的时候crash了，所以删了这些没索引的书就好了。。。也有可能建立索引后出了什么问题，那么就可以考虑重新建立，下面这

PLEASE NOTE: Once the indexes are removed from the device, the Kindle will start
re-indexing all content.

It is highly recommended the user keep the device connected to power while the Kindle re-indexes the content. Indexing of all content should complete within 24 hours, at which time the increased power usage from heavy indexing will subside.
After this point, the device should behave as expected.
