For starters... text was difficult to read against the background. Had to tilt my screen a bit to see clearly. Maybe a different color text, or a slight bit of shadow or outline?
"Computer & Laptop Repair Services & Support in Newmarket"
** The two &'s in one sentence feels a bit redundant
"Fed up
of your PC crashing or grinding to a halt?"
** Should probably be "with" instead of "of"... unless it's just said differently in the UK
It feels like after the list on the left there should be some kind of call to action. You ask all the questions... then what? Maybe add something like "Call us!" or "We can help!" or something to answer all the questions you just asked.
List on the right... last line... the dot after Local looks out of place... I get why you did it, but because it looks like it's part of the bullet list, the dot afterwards looks like a typo.
I'll have ask my GF to take a look at it... she's my marketing guru. Everything I know I've pretty much gotten from her, lol. Maybe she'll have some other suggestions.
