We can not answer, what you can to, lacking skills or tools.
how, (get it fixed in shop?)
NO PC stated
., just the same card I have GTX , that I am using right now.... as I type. MY PC is HOME MADE, ASUS based high end.
so step one is to what.?
1: try the GN246 on a known good working PC.
if that fails what do you know, in 5min work, ?
if that fails. the monitor or cable is bad.
cable is 20 times cheaper so.... bingo?
2: or take a known good monitor and test it on your unstated PC.
ok you did this, I'm talking to you and all others like you in same pickle jar. (stumped)
2 simple tests anyone can do with other PCs at home or friends that have PCs at home. (desktops)
YOU tried a 2nd good monitor on this unstated PC and it too is dead. GOT you on that. PC dead, end story on what end is dead
say it " my PC is dead." my desk top is dead. more clear.
I found my PC is dead, here is the list. NO PC stated ever.
1: I turn it on, and THE 3 FANS BLOW,
SOUND heard ,seen and felt.
I always look first, gee this one is dead,.... dang.
dead fans are #1 if dead the PC overheats fast,
some super fast. in seconds fast. some take minutes,
varies by what you own, unstated.
- PSU fan blows
- CPU fan blows
- GTX1050 has fan and MUST BLOW.
this is first. does yours....? all blow?
and all 3 not packed in lint , dirty. and running hot.?
how to the GTX1050 get there?
you added it like mine,?
Did you plug it in, not using PC power discharging CAPS
rules first if yes, you blew up the card, called HOT PLUGGING.
- pull power cord from wall, only this kills power dead !!!
- push power button, see fans turn 1 second sure, this discharges the power bus and cap.'s.(rails)
- wait 15 minutes, then pull cables and cards, or insert them,
- do not hot plug parts inside any PC . OK?
for sure not any GTX made, do that. !!!!
I have powerful PSU to handle fast powerful graphic cards
500 watts up. do you , if not fail you will.
NO PC stated, no PSU power rating stated,
no answer really possible beyond black screens of *****.
no text, the LCD would infact tell you NO Sync, no signal or going to sleep, I bet you missed that, in fact that screen tells you that
even with the Video cable unplugged, turn on monitor.
that purple tint smacks of GTX is overloaded
on line posts on PC are 99% lies, its just folks guessing endlessly and no trouble shooting skills nor training.
if wise google only (troubleshooting PC dead black screen)
Purple is outlier, but can happen but is very rare.
I bet your PC is overheating fast or is overloaded. or bad PSU
its power issue.
A PC can fail 3 ways on power.
or something shorted, in side PC that overloads that PSU
or wrong PSU used, not enough watts for your GPU.
but at turn on all GPUs use small power. so
so all I can say is do the 3 fan checks
and try a 2nd PSU. or strip the system down to min
and test the PC with minimum configuration
we call this act, , Isolation tests. (a skill set all techs know)
EG: ( the big strip down)
1: remove all HDD , DVD drives, power cables, first. and SSD if present. (yes PC Run BIOS screens with no HDD there)
2: remove all memory but 1 stick ,try all , 1 at a time.
3: make real sure GTX is in the X16 top slot !!!!
3a: all techs have a spare PCI-e low powered cheap spare GPU card in there kit (tool box) we then try this, for ending black screens.
( any old $10 card works here,no kidding, express card.)
4 : bench test the PSU?
