I don't know what's wrong with my brother and computers, but ever since day 1 with his first computer he's had problems with anything computer related. He got rid of his first and traded it for a slightly better used one from me. It was seriously working fine when he got it and it never worked with him. So we replace pretty much the entire system (new and used parts) over a period of time and it does the exact same thing as if we hadn't bought anything new for it at all. I tell him to save money and spend on a brand new one...nope...
So he gets a decent deal on a working used mobo, cpu, and optical drives. throws it in a new case and uses the same PSU, HDD, graphics, and RAM. Works for awhile and then shows up with the exact same stupid problem. So he lives with it for awhile.
What it was doing was it would decide to shut down programs randomly, crashes Firefox all the time, completely shutoff and restart the computer randomly, and just not work with some programs period. I don't know how many hours I've put into the stupid thing and it still works as if it hasn't had anything done to it. Windows reinstalled probably 10 times by now. Now it has recently decided not to boot up all the way. It will get to the Windows loading screen, then restart or shut off power. No BSOD I see.
I'm done with this piece of junk. What can cause this? I've never had any problems like this in any other computer I've worked on (I've owned and worked on several hundred systems). And the computer I have as a spare in my computer room he's taken over now and everytime he turns it on, the network crashes and I have to reset the router and modem...it worked fine everytime before. Maybe I should just throw my brother out the window, problem solved?
I told him to save money again, but he wants airsoft stuff too and he doesn't have a job yet, so... He'll get the money by 2012 or so maybe... He has no money to his name right now. He's selling stuff to get money...for airsoft, lol. And I forgot to say, the first mobo, cpu, and HDD he had replaced are all running together fine in my home server.
