Windows 10: SageMath Error code Crash my PC

Hi
W10 , SageMath 8.4, Web Browser Edge or Chrome
I report this problem because even if it is a code error on my part(QQ,9,9, is misplaced) it is not normal that it systematically crash my PC.
this little simple program made freeze Chrome (same problem with Edge), and then crashed my PC.


forget()
var('pi_1 pi_2 pi_3 pi_4 pi_5 pi_6 pi_7 pi_8 pi_9')
assume(pi_7 > 0)
assume(pi_8 > 0)
# good
m = matrix(QQ,9,9,[ \
# when I uncomment the line below (and comment the line above), then the browser(Edge or Chrome begin to freeze,
# and after a while my W10 PC crash !!)
# BAD !! Line with ERROR !!!
#m = matrix([ QQ,9,9, \
[1/3 , 5/9 , 0 , 0 , 1/9 , 0 , 0 , 0 , 0 ], \
[ 0 , 1/3 , 0 , 0 , 0 , 0 , 0 , 0 , 2/3 ], \
[ 0 , 0 , 1/3 , 1/3 , 0 , 0 , 1/3 , 0 , 0 ], \
[ 0 , 0 , 1/2 , 1/4 , 0 , 0 , 0 , 1/4 , 0 ], \
[ 0 , 0 , 0 , 0 , 3/4 , 1/4 , 0 , 0 , 0 ], \
[ 0 , 0 , 0 , 0 , 2/3 , 1/3 , 0 , 0 , 0 ], \
[ 0 , 0 , 0 , 0 , 0 , 0 , 1 , 0 , 0 ], \
[ 0 , 0 , 0 , 0 , 0 , 0 , 0 , 1 , 0 ], \
[ 0 , 0 , 2/3 , 0 , 0 , 0 , 0 , 0 , 1/3 ] \

])
v=vector([pi_1,pi_2,pi_3,pi_4,pi_5,pi_6,pi_7,pi_8,pi_9])
eqT=[]
for i in range(0,len(v)):
eqT.append(m*v==v)
eqT.append(sum(v)==1)
#eqT.append(pi_7==1)
#eqT.append(pi_8==1)
show(eqT)
S=solve(eqT,pi_1,pi_2,pi_3,pi_4,pi_5,pi_6,pi_7,pi_8,pi_9)
show(S)

BIOS error codes

So I have motherboard with installed small LED screen, which presents BIOS error codes.

Where can I find a list of those errors. And I don't mean beep codes, but the "number" codes.

Ex after installing sound card, the motherboard startup fails with the code 15.

Example picture of code is here.

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?
