I am having problems with my computer that I built about a year ago. It's had issues booting pretty much the whole time, except for a while when XP was running fine on it till one day it refused to boot. When it boots it runs fine. However I've taken to not shutting it off so that I don't have to wonder if it will boot or not. The other night the power went out and was out longer than my UPS protected against.
Asus Sabertooth 990FX R2.0
Bios version 0803
AMD FX 8150
Corsair Vengeance DDR3 1866
This is my first UEFI setup so I'm not quite sure how to troubleshoot. Sometimes the computer boots fine and other times it just sits at a blank screen with a curser never to change from that. When it boots it goes through all the lights as far as I can tell. It lights the CPU, then RAM, then Video, and finally the boot LED. When it boots normally it goes through all the same lights on the MB. The only difference is no OS comes up. It does get to the bios stage as the splash screen shows.
For a little while I thought it was a Windows 7 only problem, but it's not limited to that. I have access to multiple booting drives for this computer XP, 7, and Linux Mint all on Sata HDD and I have a bootable USB of Linux Mint as well. I make sure that only one bootable disk is plugged in at a time when testing so that there isn't a conflict. They are all single boot set ups. Windows XP seems to be the most reliable booting disk, but it doesn't boot all the time. The USB drive boots sometimes and not others.
Now if I understand correctly I can have multiple booting disks all plugged in at the same time and then control which boots based on the boot order in the bios right? I've had times where I have set the USB to boot first, but then the HDD below it boots instead. I can't figure out what is going on.
Is there a way to test my Win 7 HDD to make sure it is functioning correctly? If I boot Win XP with Win 7 HDD plugged in it shows the drive in disk management, but XP doesn't give it a letter. It shows that the drive is a GPT protected partition. I know windows 7 made some changes to the way it can be partitioned, but I'm not sure whether a GPT protected partition is normal.
Any ideas of what to check on? I'm kind of at a loss as to what to troubleshoot. I'm not sure there isn't a problem with my Win 7 setup, but the fact that I can't reliably boot mutlple OS's on different drives indicates to me there is some other issue that is hardware or bios related. However I'm not sure on how to troubleshoot that. Any help would be appreciated.
