Answer 1

I just had this update on my PC and now it will not boot. Fails the BIOS POST test with a series of beeps, completely blank screen.

I bought it only 5 days ago, have tried re-seating the RAM and GPU.

Hard to decipher the beeps as the screen is blank and I dont know what MB make it is. (8 regular slow beeps. Then a repeat of two slow low tone beeps, two fast high tone beeps - if that means anything to anyone!)

I did have some important work to do, but I guess not, thanks microsoft :(

I presume there is no way to fix this and the PC is now dead, as it wont ever boot up again now, to receive a Windows update fix ... to fix this "update fix"?

Answer 2

Please stop pushing updates on me!  I am tired of them. I like the way Windows runs right now...I am not a Luddite, I just don't want the any more wonkyness or weird Chromium hybrid crapshoots.  Please, let me be!  In seven days, I don't want to have this argument again!  If I have to, I'll look for legal means....please just stop!!!

Well, how does one selectively NOT install optional updates?

Answer 5

The latest Microsoft update has caused my audio to stop working.  This is not the first time an update has caused a problem with my pc.  If updates continue to cause problems with my pc, I will want to refuse additional updates. HELP me restore my sound!
