I have a Lenovo Thinkpad X1 Yoga that I bought new two years ago.
Last week, I began to have a problem with frequent, unexplained restarts. I ran a hardware scan, which found nothing. I ran several malware scans with a few different programs, which didn't find anything either. I turned off automatic restart. I ran disk and system checks. I looked in the Event Log for possible causes, and found no errors or warnings that happened before every restart. I was unable to find any explanation, even after extensive online searches.
Possible causes of the problem: my charger broke a few weeks ago, so I started using one from a different Lenovo laptop we had in the house. I originally ordered a new one off of Amazon, but returned it after I discovered that it was not manufactured by Lenovo. This could have caused an issue with the battery, but I have had no charge problems.
I went to Geek Squad at Best Buy today and they said it was probably a motherboard problem. Is it worth it to get it replaced? I'm not under warranty (it expired a year ago) so I don't know if I should send it in to the manufacturer. (It also has other issues that I don't need fixed, like missing keys and a cracked LCD display.) I don't want to have to get another computer with worse specs for more than I could pay to get my current one fixed. My current system cost about $1200.
I'm a sophomore in college studying computer science; I need a good laptop for coursework, and I don't have the money to spare to buy a new one of comparable quality.

Update: Regarding the charger, the specs of the one I am currently using are identical to the one that came with the computer. 20V, 3.25A.
Part of the issue is that I don't know how much the motherboard would cost. Lenovo doesn't sell them to consumers, and I still need to figure out which part of the board has the potential problem (as all the parts on the motherboard are removable).
I'm currently working on obtaining compressed air, and finding some assistance for opening up my computer.
Update: I disassembled the laptop and looked at the motherboard. Found a buildup of dust stuck to a contact between the fan and the board. Wiped it off with alcohol. So far everything seems to be running smoothly.
Update: The issue has continued, and the computer has refused to turn on several times, which disconnecting and then reconnecting the battery and letting it cool off has resolved. I noticed some brown stains around the CPU and some processors on the motherboard. Are these burn marks?
There are more, but I can't directly embed images, so I'd rather not upload them all. I think I'm going to have to either replace the motherboard, or just get a new computer. Sigh. I guess I'll get one with a better fan this time.
