MDG Garbage Computers

Ok more problems with this piece of shizit computer...It keeps shutting off if I am doing multiples tasks or after a certain period of time...So i reformatted it hopping that maybe it might of been a virus doing it because reformatting it would clean that up...Well no luck...It it all reformatted windows reinstalled & it is still doing it so it is another hardware issue...I called them & told them I am not paying for this computer because it has been nothing but a head ache & i am not going to bother to install any of my software on it...There is no since...They said they could fix it but that is useless...Too may problems for a computer that is suppose to be brand new & have duel processor so that I can multi task...So Far they lied to me when i was inquiring about buying the computer in the first place, they told me it was in home support like i had with my first dell, I had to pay $20 for insurance incase they lost or broke my computer, It took me a month for me to get my computer back from them when i sent it to them & they couldn't find it & didn't know where my computer was, I have had problems with the Power supply, fax wasn't working witch is NOT a good thing at all...DVD burner hasn't worked right since the start & I must of wasted over $100 on dvd's & now this other problem witch i think may be the processor or something over heating because after if shuts off on me I have to wait 20 min to a half hour before it will successfully turn back on for me....Please no one get ripped off by these scam artist...Take it from me & read what other people have said about this company in the likes I posted...
