Windows 7: Win 7 after update can't boot even BIOS.

Win 7 after update can't boot even BIOS.

Hi, I've got strange problem. It happened to me once in January, probably after one of KB processor x64 updates, but disappeared after another update (probably), and now again showed.

When I try to boot my computer (Asus N61jv , Win 7 64 bit Home Premium, intel core I3-350m) there is only black screen, the fan starts to speed up and CAPS LOCK diode starts to light. And nothing else. Even BIOS doesn't load. I have to reboot it about 10 times till it finally boots. Should I wait for another update for x64 processors and if it is solved shut down the win 7 updates or what??

Pls help me, cause now i'm working on my computer without shutting it off cause of fear that i could not boot it again... I sent in January computer to service but they said to me that hardware is all OK and they don't see any problem, the computer boots at their HDD (i sent computer to service without HDD).

Hello and welcome to the Seven Forums!

The BIOS is before Windows Loads. Windows Updates and Drivers are entirely for Windows, and won't affect your BIOS. Therefore, because you say that this is before your BIOS, this has got nothing to do with (at all) Windows or Windows Updates.

The only thing I can think of is a hardware fault with your computer.

I deal with Windows Update issues, and not hardware, so I really have no clue. Please hang tight for a little while, while I get one of the hardware gurus to help you.

Thanks!

Richard

Hello noreq,

This could have numerous causes, but we are going to see if we can test the power supply first.
Load up Prime95 and run the blend test for about an hour, to see if the power increase causes a crash.

You should also download OCCT and run their power supply test to see if it is bad.

The reason for this is that a bad PSU might be supplying the correct voltage sometimes, and not others. If your PC crashes under heavy load, it is a sign that the PSU might not be up to the power requirements.

If you game or anything that requires heavier power usage, you should see crashes as well.

If none of this occurs, we will take a look at other hardware causes.

Hi! Thank you for fast respond! I play a games that require huge amount of hardware usage and it never crashed. I recorded with my mobile phone a movie to show how my computer doesn't work -

YouTube - laptop issue


It occurs in 90% when I want to restart my computer. If computer is shut down, and I havent been working on him for example for a night it in most cases boots normally. I think that Windows 7 updates are guilty because from February to yesterday it worked normally and booted normally.

This sounds like it may be a heat problem because you say if it has sat for a while (IE cooled down) it boots normally. But once it is running for a time it doesn't reboot properly. You need to open up you PC box and take a look inside to make sure all the fans are running and that it is not loaded with dust.

Already done it, cleaned it from dust, but it is not exactly from overheating. For example, I boot him when it is cooled down, it boots normally, and immediately I restart him to check, and he doesn't boot. So it's not heating problem, it would not overheat in 2 minutes, and the all fans work properly.

Also when I work on him for a long time,it is not hot it's cold as normal.

What you are describing sounds more like a hardware issue rather than a software issue, especially since you say it affects your BIOS. As mentioned earlier the BIOS comes before even Windows loads, so if you can't even get to the BIOS the definitely says there's a hardware issue - maybe something over heating.

Yes, but I sent computer to ASUStek Service, and they were testing it for a 2 weeks - they sent it back with telling me everything is all right, it has to be something on your HDD (i sent it without HDD to not lost my data)

I don't know what to tell you then since Asus said they couldn't find anything. In their checkout of the machine they should have tested Windows as well so.....

Anyway I say again, if you can't get the to BIOS screen it's hardware as the BIOS HAS to load BEFORE Windows loads.

In short if you can't get to the BIOS screen, it can't be a Windows problem. So that says it's either hardware, or a virus in the BIOS.

Again If Asus checked it out and say they can't find anything well.....

Since ASUS said that it could be the HDD, why not send it back to them with the HDD in place stating that you continue to have this problem? Before that, you may backup all your data and keep it since that was your worry.

If you are a DIYer and experimenter, you may buy a new HDD and try any Windows7 installation for a month without activating. You may borrow one Windows7 Media from a friend for this or download the ISO. Goggle and you will find it.

Look at it anyway, this is a tricky intermittent problem that requires a lot of continuous monitoring and sustained trials to pinpoint the cause and resolve. If it were a Desktop, I would have suspected the power switch.
