I've checked all other threads on this and haven't found a fix yet. But first here's a little background.
We have the Acer Aspire TC-220, and it's been a wonderful computer for around 3 years. About 5 days ago, windows had an automatic update that completely messed up. I spent days with Microsoft tech support trying to fix the issue, and even though we lost years of files and beloved photos (string of bad luck, our backup hard drive for the photos had a freak accident a few days before) I was just happy to finally have the computer working again.
Everything was fine for all of 6 hours. Then windows got slow, really really slow. Naturally I restarted the computer, but it then got stuck in a reboot loop. It would get to the acer logo screen, load, and then restart unless I intervened by opening BIOS or the boot menu. It was around midnight at this point so I just turned it back off and figured I'd sort it out tomorrow.
Now for the current problem. Woke up this morning and tried to boot it, and it loads to a black screen with the Acer logo, and in the bottom left corner it says to press del for BIOS, and f12 for boot menu. There are no loading dots underneath the logo, nothing. If I just leave it, it sits there (longest I've left it so far is 2 hrs). If I press del or f12, the text in the bottom left corner changes to "please wait..." and it just sits there, for hours. At no point do I get any little loading dots or symbols.
So far I've tried restarting, unplugging the power and "dissipating charge" or whatever tech support said, putting a windows 7 disk in, putting a bootable USB with Ubuntu in, opening the pc tower and blowing the large amounts of dust out, unplugging literally everything (monitor too) and letting it sit, then plugging it all back in. It all brings me back to the black screen of death.
I really hope this stupid Microsoft update hasn't messed up the actual computer or anything. Microsoft tech support so far has been useless, they keep recommending troubleshooting options that I've made clear I don't have access to. Acer tech support tried to help, but say I should take it to get fixed or checked somewhere nearby me. I'm not spending money on something that's not my fault, especially considering I don't have any money.
So what can I do to fix this? As of now I just want to completely clear everything and start fresh with Linux but have no clue how when I can't open the boot menu.
Thanks in advance for any help.
