@ bilstar,
Most certainty a two-week-old “New” Computer has a Guaranty/Warranty.
Perhaps it would be worthwhile to return your “New†Computer to the retailer and explain to them in precise detail your long-standing unresolved problem and have them attempt to get to the bottom of your long-standing unresolved problem.
In reviewing your other 5 Forum Postings in your posting titled “DVD stops reading DVD-R†(http://club.cdfreaks.com/f61/dvd-stops-reading-dvd-r-217371/#post1845477) this appears to be an ongoing problem of yours with your ProEvoltionSoccer disks and other DVD Media for quite some time.
Perhaps in seeing this is an ongoing problem you are having with both your “Old†and “New†Computers there isn’t anything “Wrong†with your “New†computer but with your DVD Media and/or your Media Burning procedures.
Regards,
