Windows 7 - SSD UDMA to PIO Mode 4 HELP!!

hi, now this is a shocker to me since everything was fine untill i turn off my computer, then installed a new Fan to the side case.

now since i rebooted im stuck in PIO mode 4?

SSD is 0 installed SATA ACHI enabled in bios.

SSD Channel 0 - Reads as - PIO Mode 4?

1TB SATA HDD is on Channle 1 Reads as - Mulity World DMA Mode 2?

DVDRW on Channle 2 - Reads as - UDMA 4 - Normal..

now this is bugging me since i can not switch back to UDMA 5 even if i uninstall all the drivers on them channles..

reboot and bang, still pio.

other thing i did was switch to IDE mode, boot and then uninstall as it was still pio.
switch back to ACHI and thought that would cure it.

ive took out everything & even unpluged the DVD to boot as i thought it might be that.

since ive install the pagefile onto the 1TB (save room on the SSD) if i dont have it pluged in on boot when windows loads you get that error about pagefile ect..

so guys, help!! i have no idea why this is not running in UDMA 5 like it was.. after a fan change and power down of the system for like 20 mins?

any information will be great.

anyone?

ive now installed my mobo SATA RAID (i dont use Raid) and now everything is on just 1 controller..

IASTOR? now ive read about people saying that this driver is not as good? yet im finding it just the same.

anyone with a input.

ok well i uninstalled that iastor driver since i read it dont have Trim Support?

once i did that im on UDMA 6 now? crazy stuff.

i thought someone would help.. o well
