Hello, I am using an HP Pavilion DV4000 laptop, but it lags even while watching YouTube. I use 1gb and 256mb ram, the processor is Intel pentium 1.67ghz HDD, it is very slow and that's why I want to install an SSD instead of HDD. Is it possible to replace these parts? Which components do it support the most?

Should I have my screen replaced or is there anything I can try before I take it to a repair shop? My computer powers on but the screen is black (off). The white lights above the scroll button & the caps lock button blink, but that's all that happens.
