Machine fed up-ness

My "beloved" laptop is going thru what you call, everyday-sickness....yes from me and itself. Its continuing problems gives me much headache and i can say i've almost lost it all with it. After 5 times reformatting, it's worst than it was before. Before that, it just likes to hang for no apparent reason. with each solution comes further complication....and i've resolved to the last solution i have..................to sent to ACER themselves and kick the brains out of my laptop.
