When it rains it pours

where do i even start? I have a Alienware, M11xR3, laptop i know its old but she is my baby. So i recently got a SSD for her (KINGSTON SUV400S37240G, which i found out to be rubbish.) I also juiced the ram up as well from 4 gig to 16 gig my problem is that i had windows home professional 64-bit sp2 which was fine never really had issue with it. but the computer guy that did all of the above for me, has put sp1 on my laptop now i am getting update errors constantly an to think that this was only the start of my troubles is what kills me or was it wasting $300 not sure. So i decide to see if i needed any driver updates well as you could imagine yeah i did and at a guess i think i need around 20. I first went to Intel after all it is their processors well most of them, did the little system test they suggested an well i only needed 2 according to Intel. Then thought i would check Dell support site ( who i purchased the laptop through after doing the little system test they recommend 20 now by this time i am pulling my hair out an thinking that i need a rather strong drink. But i am stubborn so went searching for more opinions all of which varied and were all over the place, i started feeling like i was trying to capture a rare Pokemon (never have but seen enough videos as we all have.) Then i got some gusto about me an decided i would spend some money on a site, thinking this would help me resolve all of my issues how very wrong i was. I did 1 update and it had rather big impact on the performance of my system slowing it right down. So I kindly sent them an email to which i have got no reply. However i think i managed to remove the driver update from my system. Although its still not 100% the SSD has slowed right down an is not preforming the way it should. Please help me as i really dont know what more i can do at this point apart from pouring myself a nice strong drink.
