i bought a Alienware 17 R4 not long ago knowing that the machine was defective,

i was able to "somewhat bring it back to life after a full rebuild.

did a lot of work on it such as new thermal paste and new thermal pads, new cmos battery, new hard drive, new battery. i also did update the bios to 1.17.0. Thinking that maybe, by doing all of this would perhaps bring the machine back to life. it somewhat did, but not quite there.

the symptom that i have is that once windows installed in SAFE mode, the machine will boot fine. i see graphics, it installed windows beautifully. once i boot in normal mode? i get a black screen once i see the window logo, then the fans speed increases slightly. not at full spin

Not entirely sure what is going on with the machine

i did all the self test and diagnostics and it passes in all flying colours. no issues according to the test.

the os installed is windows 10

thinking that it could of been a failed attempt of the bios update by the previous owner, i have downgraded the bios to 1.10.0, still a no go. i did the bios recovery, still a no go. brought back the 1.17.0 and still a no go.

is the machine bricked?

Looking for any feedback or solution to revive this machine as it is so close to work, and yet so far.

booting also into bios or "POST" works beautifully as i have no issues in that area. doing the diagnostics "pressing D while powering up" works, but passes all test.
