Laptop suddely slow after BSOD

[SeanShawnShaun]

I have a very Thinkpad t61 from 2007. It's been extremely reliable and fast until one day; I was using it to do some research on the internet then it suddenly gave me a black screen. Because my research was due the day right after, I didn't try to fix my computer. Instead, I just carried on my research on my iPad. The next day, I attempted to power up my computer, and it successfully powered up, the processes were running as normal, but I couldn't see a current screen, it was just dark. I connected my laptop to a monitor and could see a screen. I noticed that my laptop suffered a severe performance drop. It was five times slower. Even youtube videos where choppy. After severals attempts to revive my computer, I ended up giving up. A month later I tried to boot up my laptop again and it self repaired itself. It could now display images on the laptop screen, but it was still very very slow.

If anyone has a solution please tell me.

here are my specs:
