I'm going to be as ridiculous detailed about the problem as possible. First and foremost the computer won't load grub dual boot loader. It has recently been reliable at loading "Checking NVRAM" and that makes it either show "read error" or "grub recovery". It's an Asus computer and so has an Asus motherboard.
Secondly, when I try to live disc boot from a usb-based distro I get the error "No caching mode page present".. which hadn't happened before.
I figure these things are specific enough that a fairly accurate guess could be made by someone familiar with hardware. I hope I'm right.. of course.
Finally, one thing I've been experiencing recently is my Linux Mint 13 operating very slowly, hanging, then returning back to normal speed, then hanging again. I thought it was happening during times of software load on hardware but I eventually had nothing running that used a lot of energy and it was still behaving slowly and/or unresponsively.
I'm attempting to diagnose it myself, assuming it's a harddrive failure or harddrive communication failure, but I was expecting the LIVE boots to work without a problem. Because they didn't I'm worried that it might be a "non-volatile RAM" problem... or some other motherboard issue. This would be disappointing even though it is a 5 year old computer.. and a laptop at that.
I'm going to continue trying to get it to load an OS by trying a LIVE OS again with the failsafe methods and if that doesn't work I will connect by old hard drive up via USB and try to boot Xubuntu... really old version but still runs perfect.. edition.
Update: Failsafe modes on flash usbs didn't work, not surprising. the USB harddisk doesn't seem to work, I think it only worked under grub.
To clarify, I seem to be able to get to "Grub rescue" after it says "unknown filesystem". On the Failsafe usb boots it continues to try booting after the messages (three) "No caching mode page present". But it fails anyways (doing the write-through, i think).
