Ok, so before formatting i decided to set AHCI mode in the BIOS and boot into Windows... just to try, and BAM, no more constant Led flickering, just the normal LED activity. Also, my boot time is now way faster, like 5 seconds faster, or more, than IDE (as fast as it used to be). Unfortunately, my mouse driver software isnt always showing on the bottom-right tray (nothing new here, it already happened before i switched to IDE, the driver is loaded and working, but the software tray doesnt show up), and when it shows, then my Keyboard doesnt work (i have to unplug and re-plug it to get it working... still, nothing new here). Very strange and random issue, im starting to think it may be due to the ultra-fast boot i get in AHCI mode (seriously, its ridiculously fast). Keyboard works as long as the mouse software doesnt show in the tray, or if i prevent either the mouse software or the keyboard software from loading in the windows boot by "msconfig". Pseh, i will try some tweaks in my boot sequence or something i dont know, but im definitely not going back to IDE... so yeah, AHCI worked for me in this case, tnx for the support guys.
Doh, srry about that, thanks for your time Wendy
