BB Torch :: 9810, Won't Respond, Won't Power Up?

I am quite unhappy with my blackberry 9810 and with Research In Motion at the moment. I noticed my phone would suddenly go off and restart. Only a few weeks later, it wouldn't restart by itself after suddenly going off. I had to restart it whenever i noticed it was off. But it got worse, it later would not respond at all after it had gone off and it would sometimes take a whole day to start. It was then I went to the ResearchInMotion site.

Nothing specific. Only links in the help forum to crackberry.com. I read the many stories I saw like "put your battery in your palms and rub it till it gets warm" and "use a short cable to connect your device to the laptop"... I have swithced batteries to be sure it was not a battery fault. I have re-installed the OS, upgraded to 7.0 and used the Loader.exe countless times. Those worked only like 3 times after days and days of labour, many missed calls, records and events in my planner. Often, it would work for one day and then go off for two. It has not worked for 2 days now and non of these troubleshooting work again; no red light indicator when i connect it directly to the laptop using a USB cable, nothing.
