Hi everyone,

I'm really stupid and tried undervolting my CPU from the unlocked bios options(I changed the setting in overclock to override and applied -60mv). After which my laptop has been stuck in a bootloop, my keyboard lightning does turn on but my screen shows nothing and after 10-20 seconds it reboots and keeps going like that forever.I was hoping I could hardreset my bios, so first I tried keycombos like alt+f10, then I tried to insert a paperclip to press the button labeled "SW3" on the mobo, then I tried manually pressing the sw3 button with my hand after removing the backcover, then I tried shorting the pins that have "JCMOS1" written next to them located underneath my RAM chips using a screwdriver, after which I tried completely removing both the battery connector and CMOS connector.Nothing I mentioned has worked and my laptop is still stuck in a bootloop. I really need it for school but I don't have the money to purchase a new one right now. My warranty has expired and I've seen other users on this forum say they had to pay for a whole new mobo when they send it for repair to acer. I know I've been extremely stupid to try this on a laptop and I'm worried it's dead forever. Does anyone have an idea that I can still try? I'm attaching pictures of my mobo just incase.
