My friend spilled milk on my acer aspire and messed up my keyoard I got a new keyboard but now it starts up and runs great for a bit and then shuts down at random times. I tried changing the hard drive and it still shuts down. I think it might have something to do with the motherboard but i want to know for sure before i have to get a new one.

A short, practical triage to narrow this down without assuming a full motherboard replacement. This complements points raised by (many components can be affected) and (cleaning may help), and focuses on reproducible checks that separate power, thermal, memory, firmware and corrosion problems.

Recommended diagnostic order (do these one at a time and document what changes):

  1. Preserve data first — remove the storage device and image/clone it or attach it to another PC.
  2. Minimal-boot test — disconnect all nonessential parts (optical drive, HDD/SSD, wireless card, external USB devices), boot with one RAM stick (swap to test modules), and run the machine in BIOS/UEFI idle. If it still shuts down in BIOS, the problem is almost certainly hardware/power-related.
  3. Power isolation — attempt AC-only (battery removed) and, if possible, battery-only tests; verify the adapter output with a multimeter or a known-good adapter of the same rating.
  4. Memory and OS checks — run memtest86 from USB for several passes; boot a Linux live-USB to see whether the shutdown is OS-specific. Also check Windows Event Viewer (Windows Logs → System) for unexpected-shutdown entries (Kernel-Power) if the OS is running.
  5. Visual inspection and safe cleaning — inspect the board and ribbon connectors under bright light/magnification for corrosion or residue. If residue is present, professional cleaning is safest; controlled cleaning with 90%+ isopropyl alcohol and a soft brush is a common DIY option, followed by thorough drying (24–48 hours). Avoid powering the machine repeatedly while residue is suspected.

Notes and next steps: overheating problems usually reproduce only under load; hardware/power faults will typically kill the machine even in BIOS. If the failure points to the motherboard/power circuitry, compare a board-repair quote versus replacement cost. If any step shows definite hardware failure, professional board-level diagnosis is recommended to avoid further damage.

laptop? Not good, could be motherboard related. As you may have experienced, all of the parts within a laptop are tight, but liquid can easily slip through an affect multiple components. without exchanging components, it woud be difficult to advise since it could be just about any thing inside the computer that could be causing a short.

ur mothrboard needs some cleanning there r short circuit always but on boot the laptop use othr poarts than when laptop goes through when finally come on and load every thing ! c this hort circuit maybe at bios unint* just send it to the customer survice to clean it with some dielectric liquides..or u can take th risk and clean it with lcd screen cleanning kit! but just buy expensive high quality ones ...awater be4 spilled on my pc keyboard and it do some short circuit even after dry! but just clean it it comes back alive and it works!
