[QUOTE="AtlBo, post: 698656, member: 32547"] Well, here is the latest on this PC. Powered the PC down to take a look at the internals. Disconnected some things, etc., and it went back to an old problem where the fans would come on but that's all. It was that or the PC would get through the BIOS screen right to where Windows starts to load and then the PC would completely shut down. So tried various combinations of disconnecting things and reconnecting and then the RAM memory and a different power cable for the PC. Also, cleaned fans and wiped a little dust out. I had cleaned it about 4 months ago, so it wasn't dirty without alot of use. At any rate, after each of these efforts no success. Well, finally I disconnected the power supply to the motherboard and reconnected that and, through another reboot, managed to get to the BIOS screen and into BIOS. Previous to this point the PC had basically quit posting the BIOS screen ever with nothing but spinning fans, so I was encouraged. Now, I rebooted and let the PC go through BIOS screen. That went fine, except that I got the message that Bootmgr was missing after the BIOS screen. So here's the sequence after this: 1. Back into BIOS reset BIOS settings to default->positive effect where SATA connectors reappeared for the board 2. Reboot and went through BIOS screen but still got the message that BOOTMGR was missing. I was a little bit puzzled now 3. Used W7 disk to repair the issue via startup repair but no go 4 Used W7 disk to repair the issue using command prompt still same message 5. Back into BIOS to see what I could see not really knowing what to look for. Well, I chose the settings for the IDE drive, when it occurred to me. OK, PC is seeing the IDE as the Master. Well, the only options for IDE Master are AUTO, Manual, Disabled. I thought OK, maybe if I disable the IDE channel, the PC will fall back to the SATA connected drive with the OS and boot into Windows. 6. Rebooted and yep, sure enough PC booted right into Windows. 7. Looked in Explorer.exe, and the IDE drive is showing even though I disabled the channel. What? Oh well, I would have thought the Manual setting was for using the IDE channel for a backup. 8. Open Task Manager and uh-oh processor is at 100%. What? Task Manager shows as using 70-90% of the processor but no matter what I open or close the processor reads plastered at 100%. HWiNFO says temps are at 40C however. OK, this is a little bit higher than normal for this PC to date but what is going on? 9. Reboot and wait, and everything back to normal. Processor at 1% and temps at No idea what happened there. 10. Mild rejoicing :D Disconnecting/Reconnecting the power cable to the motherboard was the answer. Resetting BIOS did some good though, since I could at least see the SATA drive connectors in BIOS again. PC is running much better now. Thanks for the help so far. I will post if there is more. I think this PC is likes drama so who knows what is next... [/QUOTE]
