ACER 4520 BSOD issues 0x0000C1F5

Hi I really hope someone can help. ACER 4520 will not boot win at all. I have used everfy option in f8 none will work. Just BSOD every time with same error 0x0000C1F5.
However I did get system to change somewhat when I used
Left ALT/F10 which does a forced previous 1 day earlier restore. Now I get
A screen if I hold down space bar while attempting boot, it says
WINDOWS SETUP [EMS ENABLED] when I tried that option it starts to load windows
With a white bar bottom screen saying windows files loading,
Then after about 15 to 20 seconds it BSOD AGAIN with same error message
Now if I try safe mode attempt, doesn't matter which safe mode I use, it tries
To load win & even looks like its going to work with the normal window bar
Which appears during loading attempt.
System:
Vista home prem
Acer aspire 4520
AMD TURION 64x2 mobile tech
TL-58 (1.9ghz, 2x512kb L2 cache)
751mb NVIDIA GFORCE, 7000M turbo cache
2gb ddr120gbhdd
Dvd supr/multi dL

I have checkd all memory & hdd devices all are ok.
Mem test passed as well. Cpu is ok, cooling fan works.
I even took lappy totally apart cleaned all frome dust & reapplied cpu amd with gunk
I also pulled cmos battery from pc for several min around 10 to 15 min
So bios was completely reset.
After putting unit back together I attempted reboot
Going to f2 bios setup screen setting unit to default settings.
A no go. Just same crap BSOD with same error.
I may be wrong but I think that error is a corrupt file error?
Does anyone know?
Anyway if anyone has a clue please let me know.
Thank you, blitzer ;\
