Computer Hard Drive Crash

Finally the internet problem was solved BUT when I went to turn on the computer nothing happened....at first. Finally got it up and running but then it showed low disc space.....BUT now nothing happens at all.

I have a new hard drive coming but won't be here until the end of next week.....I'm cgoing nuts without my computer and only a very old iPad (one of the first ones ever out I think).

Looks like I'm stuck until it's fixed, then it's major catch up time......:-(
