About a month ago my computer went on the fritz. It will turn on, but will not start up. I cannot run it in safemode - the only thing i can get to is the diagnostics otherwise it just keeps RESTARTING itself. Any advise on what to do? I have left it off and unplugged for over a week, TRIED changing the power cord ( around the same time this started happening the electric has been shut on and off while the computer was on, which may have affected it) so I'm out of ideas. Is this a lost cause, is there anything i can do, or should i try BRINGING to a professional?
I'd LOVE to try to get this fixed on my own so all help is appreciated!

Also, if this computer is unfixable is there any way to get all my pictures/videos/ documents off of it and transferred to my laptop?I can't tell you how to fix it as I'm not that expertised, but I do know that you can buy a hard drive caddy that you slot your hard drive into and then you connect it via USB to your laptop.

You can get them from any major computer store.Okay cool, at least i can get the important stuff off. Thanks!Just buy the right type of enclosure, a EIDE won't work in a SATA enclosure, and vice versa.
