I use a hard drive bay for different OS's. My Phenom system was built in 2009 and haven't had any problems til lately. I occasionally (three times this year) go to boot up and dies mid- bios w/error 'disk error.' Switch to internal sata cables: same. Switch out same cables: same. Last time I switched boot order, popped in a Linux Mint CD and was able to read data off a usb case (both hard disks) but only after 2nd try. Then used drive bay again and all was well for 3 weeks. No viruses.
This week, was surfing and mouse locked up. No keyboard so shut down.Re-boot didn't even go thru bios. Just a black screen. Day later was fine. Wondering if next time I should try re-seat memory and/or re-plug power connector. Tend to think it's a mobo issue.
Very odd. Appreciate any hard won expertise as I'm thinking I have to somehow afford an entirely new system since this one's not reliable and the symptoms could get worse.
It sounds like a slowly failing hard drive to me.
Nope. I use a hard drive tray for different OS's and all drives are new.
The new HDDs where purchased when ?
Try doing a full BIOS reset, load Optimized Defaults for your mainboard >>see mainboard manual if needed.for details.
See if you have the latest BIOS installed for your board.
