Ok, this one is weird. Lots of moving parts here so I'll just list them off and maybe someone can flag one of them as a cause.
I built a new system, ASUS EVO/USB3 MB, AMD 6-core, 8GB DDR3, SATA II HD. Everything was fine for a month or two.
Couple days ago I added 2 things: a GTX 460 graphics card, and a shiny new copper heatsink. After doing this and plugging the HD and DVD drive back in it wouldn't boot. It was saying something about No bootable drive found or something. If I hit F8 I could specifically choose the SATA HD and it would boot ok. But I didn't want to do this every time. So I moved the sata plug around on the motherboard - there were 5 plugs all right next to each other - this didn't seem to help. I went into BIOS and changed the boot order around, and now it does boot without F8 or any other intervention.
But the boot is CRAZY slow. The ASUS POST screen will sit there for like 15 sec, when it was 2 sec before. Then the windows 7 logo comes up, and then black screen for like 30-45 sec.Then windows comes up most things run fine but certain programs just hang.
- Games load in normal times and run fine
- Most programs load ok and respond well, some randomly freeze
- HD fragmentation is around 8%, no problem copying/moving files
- Heat levels via SpeedFan are good, idling at 35C, peaking at 45C
- GPU heat is good, idling at 30C, peaking at 53C, games run smooth
- No viruses that I can find
So did I screw up the SATA plug? Did I screw up something in BIOS? I thought maybe it was a windows 7 thing, but how would that account for the slow POST? Could it possibly be one of the cores of the CPU gone bad? If so, how would I check that?
Any advice would be greatly appreciated.
EDIT: What really confuses me is the 5 SATA connections on the MB. Are some of them SATA 3.0Gb vs 6.0 Gb? If so, is one of the the 'primary' or 'master' plug? I have 1 SATA 6.0 HD, 1 IDE DVD Burner, and 1 External USB 2.0 HD.
