A few months ago my power goes off while I was working, when I turn my system back on I get the loud error message coming through speakers saying it's being overclocked too high. I don't overclock at all so I turn it off and try again, this time it starts up perfectly. The next time I try to boot up, my SATA drive appears to be completely blank. I had a deadline so instead of tying to figure it out myself I took it to a shop. $75 later and its back to normal with no data loss. The guy said he just changed some bios settings to fix it. I really wish I had had a longer chat with the guy because the EXACT same thing just happened again. I don't have a deadline this time so I'll try to fix it myself so I can spend my money on a new PSU and a UPS. Does anyone have any ideas where I should start playing around in the bios? The HDD is being recognized but it's saying there are no active partitions.
