Why is my new computer shutting itself down? Pls Help

I've had this computer a few days and tonight it shut down unexpectantly. When I turned it back on got a msg saying that I had 2 files that the dump file was in. 1st one couldn't even find because the path they gave me didn't exist, 2nd one found but when I clicked on it to look, I then got a box that said Windows couldn't open etc.etc. so let Microsoft find the program to open it. Got a program called WinMaximizer but was not quite comfortable using that as I didn't really understand why that program would open it. When I hit the button that said 'Find Errors' it gave me 1254. Don't understand how it could possibly find that many errors when I've not even had it a week. Have several other problems going on but this seems serious since the system shut down while I was out of the room. When I tried to recreate my steps so I could write them down, I really screwed up and instead of letting Microsoft find a program (they found WinMaximizer), I ticked the one where I could find my own program. When I looked at the programs it seemed to me the only one that made any sense was Notepad so I picked it. I didn't see the box that was checked "use this program every time for this type of file" until I clicked the box and I seem now to be locked out of that file. There is a little lock on the side of my Username file and a lock on the Minidump file. Brand new to Windows 7 so don't where to find out what that means.

Gateway ZX 4951 AIO Touch PC
Intel Core i3

I need to do a backup & recovery for Gateway and Windows but don't want to do them until I get this cleared up. Gateway wants me to use 4 DVDs and I wanted to use my portable hard drive so gotta figure that one out. Hope someone can make sense of what I've done.

Re: shut down

A sudden shutdown most often is caused by some hardware issue. Could be insufficient cooling or insufficient power. That's a warranty issue (unless the cause is software, of course).

Winmaximizer is just one of the million registry cleaners we don't advise anybody to use. So just uninstall that.

Now how to continue?
As I said, a hardware cause is the most likely, but before Gateway will honor that warranty request they'll have you go back to factory conditions indeed to exclude software causes. So just do that - following the procedure detailed in the manuals or on their site - and see what happens. Then apply Windows updates and install your antivirus and wait for the next crash. If it was malware, it won't happen again (until you allow it again on your machine, of course).

When it crashes again don't look at the minidump (you won't understand that anyway), but look in the event viewer for cues. Armed with that knowledge, contact Gateway again and arrange for a repair.

Thank you. I've uninstalled WinMaximizer. Checked event vwr...found 6 critical for "Kernal Power" and 15 warnings about "WLAN Autoconfig" and WLAN Extensibility Module" in System, 5 warnings about ntfs...what concerned me was explanation "the system failed to flush data to the transaction log and corruption may occur". 18 warnings ".NET Runtime Optimization Service" in Application. There were no hardware events. I haven't put on any software except for those I trust and have used before. These events have occurred from 5/13 to now.

What is the best way for me to learn what the different things are in the event vwr and what to do with them? Or am I always going to need an expert. Looks like I need to look at this on a weekly basis. I appreciate the help you've given me.
