My dell inspiron is freezing know what should i do if you go on the desktop and go on a programme it freezes after a while

My brand new Dell laptop also has a freezing problem. It seems to mainly happen with media player or if I adjust the volume in the taskbar. I called Dell Technical Support and they did a remote access, which seemed to work, but then a few days later, the same freezing problem occured. I called Dell again, and they suggested that it might be the automatic updates that were causing problems, so I disabled these updates. But then, a few days later, the computer played up again. I had to call them for a third time, and they told me to restore the computer back to the original factory settings. After doing this, the computer froze yet again, so I got back on the phone and was told to restore the factory settings again. When this still didn't work, they told me to re-install Windows 7, which not surprisingly, still didn't solve the problem. Today I called Dell for the SIXTH time, and they told me that they're going to send a technician to my house to replace the motherboard as well as several other parts. This technician will supposedly call me tomorrow to arrange a time to come to my house. So, after six phone calls and feeling very frustrated and angry, I sure hope that replacing these parts will once and for all solve this problem. I will not be buying Dell ever again and I definitely wouldn't recommend Dell to anyone else.

There could be couple of resons for that firs of all try to make Dell 32bit diag, if there will not be error codes try to remove memory, try reinstal O.S and if comp will freeze during dell diag then its HDD sector error then only repleace HDD
