After last Windows Update Win7 64bit ultimate will not boot

I have Ult in both machines, and I heard the last 2 updates triggered a full-page nag screen, so I skipped them.
Disable Your Windows 7 PC is Out of Support Full Screen Notification

I experienced that screen on my last boot-up. clicked remind me later then got to my traditinal desktop. Clicked on the windows update Icon and saw there was one more important update. proceeded to download and install. then shut down.


after that the computer will not boot, nor display anything hence why i am here searching for possible answers.


I have no way of disabling the notification as i cannot get into window, safe mode nor bios.

This looks like a hardware failure to me, either in your motherboard, CPU, or even power supply.
Windows update can't break the BIOS.
Coincidence? Well more likely the power cycle restart triggered the failure.
If you can't get into the BIOS, or the BIOS startup screen does not display on restart, the problem is h/w, not Microsoft.

Hi

couple of things to try
question first AS SOON as you boot do you see the cursor VERY briefly, then it dissappears, top left corner

from a cold boot IMMEDIATELY hit/hold the Escape key, does it give you a bios screen
next
Reboot hit escape then your F? bios entry key

reset bios by removing the CMOS battery

Nothing ever displays on the screen. so no cursor not even briefly.


Attempted all that you suggested..... again still nothing.


In further research i learned that a LED light near the centre of the motherboard is for the CPU. I had originally thought just to indicate that it is on. I believe I have read that when it is lit, it means the cpu or the bios has a problem. Can anyone confirm this? If it is the CPU I presume that would prevent the whole thing from working. Really strange coincidence that the update to re-start miraculously happened to be perfectly timed for one or the other to fail? I fear the last update might have adjusted some setting or code and perhaps did the CPU in.


I am going to look for an inexpensive AM3 chip to place in the 941 socket (hopefully the same one i have) and see if that remedies the issue.


any further thoughts from anyone.?


thanks for the suggestions

It looks like a hardware issue, which is just coincidence that it occurred around the time you did your update, but nothing to do with Windows. A no-post could be caused by anything from an unseated DRAM module to a full-blown mobo failure. Unfortunately there could be a lot of work involved in trying to locate the cause, unless it's something obvious like a loose DRAM module or unattached cable, eg to the GPU etc.


I would recommend watching this video (37 mins long) which gives some very helpful ideas as to why no-post can occur, using a Ryzen build as the example.

I had once same problem.
Unplug the power cable from the power supply, wait 1 minute to discharge the capacitors.
Open the case side panel and remove the memories. Gently clean the memory contacts and spray the slots with a contact cleaner.
Insert one stick at a time and try to boot (leave the computers without drives)
If it boots, power off, Unplug the power cable from the power supply, wait 1 minute to discharge the capacitors and insert another stick etc

Do you have a MB speaker? Can you hear an beep?
