I have a Lenovo Z510 laptop running Windows 10. Intel i7 processor and an Intel 4600 graphics card.
I've scoured the internet for help with my problem, but haven't been able to find anything that quite matches what I have going on. Starting several months ago, my computer started randomly crashing, but only when it is plugged in. I troubleshooted everything I could think of (graphics driver, AC adapter, the battery, the port the AC adapter plugs into, etc.), and believe I've finally found it to be an overheating issue. This is because when the case is removed from my laptop, or if the laptop is placed on a vent blasting A/C my computer doesn't crash while plugged in. As soon as the case is put back on, or the computer is taken off the cool vent, my laptop crashes within minutes. I've replaced the fan and reapplied thermal paste with no success. The AC adapter does seem to have some effect on the crashes, but the AC adapter that never caused the computer to crash shorted out recently. I'm wondering if it's a mix of electrical issues causing overheating? Or maybe malware causing overheating? I'm not sure, but the computer rarely feels very hot when it crashes. Even if the computer has been off for hours, and is turned on while plugged in, it will usually crash within seconds, so I have a hard time believing it's solely an overheating issue. But the fact that cooling the computer over a vent prevents this makes me think it is part of the issue. Any ideas? Thanks for your help.
