Re: tried everything but replacing motherboard
You said it keeps getting slower. Ok you dont really need to change anything hardware wise as a computer should run as fast as it was when it was new the only problem that could cause it is software problems or malware. As you did nt mention running anti malware software i would suggest that first.
Go to www.malwarebytes.com then run the free trial option. Just select download on the middle of the page. Download and install and make sure to do the full scan once prompted. It will take a couple of hours. Make sure not to heal but delete.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

There could be a number of things wrong with the system that would cause it to randomly reboot.
1. Try an antivirus scan. Use a good, trustworthy antivirus software to scan for viruses. There are good, free software programs out there such as Avast! Free, Avira Free and AVG Free, if you don't already have an antivirus. 2. Is the computer overheating? Check to make sure your rear vents on the computer are not blocked or obstructed. If you aren't scared to open up the case, check to make sure it isn't clogged with dust. You could also try to check for faulty cooling fans inside the system. 3. Is there a problem with Windows? Have you made any changes to Windows recently? You can try a system restore, defragmenting the disk or running a disk cleanup.
First of all if you have Symantec Norton Antivirus Products or McAfee Antivirus Products remove them. They are core hogs and will slow your system down. Replace them with a simple and smooth FREE Antivirus such as AVG, AVAST or Microsoft Security Essentials. Secondly if you have anything on your system from AOL remove it. It too eats up resources. You might have a virus that is slowing you down also so after you install the FREE antivirus program run a scan. You'll be amazed at what the antivirus you pay for missed. Download and Install MalwareBytes and run a Quick Scan. After you've done all the above Open My Computer and Right Click on your C: Local drive and select Properties, then Tools, then Defrag Now. When the Disk Defragmenter opens click on Analyze and it will tell you when it finishes if you need to Defrag the hard drive. If you need to Defrag the drive click Defragment. This will take more than an hour to run so be patient.
