I have an Asus U52F Laptop, the Core i3 version (Very old, I know) running Windows 7 Home Premium 64-Bit. It was given me to my uncle, so I didn't buy it, therefore don't know where it's from. When I turn the computer on, it instantly attempts to login to the administrator account, but then automatically signs back out. I can log into the other two accounts that are not the administrator, but when I do the desktop is black and the task bar shows nothing. I tried to open task manager to run explorer.exe, but it didn't work. I thought at first it was a virus, since it tried to login to the admin account although it failed, and the amount of downloaded junk on this thing is crazy. Then I thought, maybe the HDD is failing. Recently I tried to run it, and it said something it needed wasn't installed. Soda got spilled on it, the battery was removed right after; but the keyboard no longer works. That wasn't a big deal, I just got a USB one. About a year later these problems started though. Task Manager also says that the Disk is at 100% use, the Memory at 29% use, and the CPU at 11% use. This hints me to thinking there's a virus, those are VERY high values for being idle. Any help is appreciated, thanks for reading.
