2008 iMac really screwed up

[aar2697]

This machine has been letting me down a lot lately. First of all, the computer beeps about 20 something times early in the morning when I'm trying to sleep. I have not found ANYONE on the internet with that same issue. I've been through pages and pages of google and still no luck. Next thing, it randomly restarts whether if it's on Windows or OS X. Sometimes the computer gets really hot and goes "BEEP BEEP" at about a million decibels. I've also have had extremely slow Internet. It's slower than dial-up, even if the iMac is right next to the router. It's been two years, also, and the manufacturer warranty has expired and I'm not legible for apple care. Any help?

Your heat issue confuses me as do the beeps. Sounds like a hardware issue.

But I would save all your data and reinstall your operating systems.
If this doesn't fix your problems then you have a hardware issue.

Months ago, January I think, I had to restore to computer because the keys were out of order and there was missing HDD space. From there on started a treacherous journey of "BEEEP BEEP BEEP BEEP BEEP" (not loud though, just smooth and soft)

Well I would do a clean install
But I would guess it's a motherboard issue
