When I turn my pc on, windows starts loading and it shuts down before getting to the logon screen.
I need three of four attempts in order to get it going. I noticed that if I go into safe mode and reboot from the logon screen, It doesn't shut down.
Any help appreciated!

While in safe mode....

Go Start>Run (Start Search in Vista), type in:
msconfig
Click OK (hit Enter in Vista).

Click on Startup tab.
Click Disable all
IMPORTANT! In case of laptop, make sure, you do NOT disable any keyboard, or touchpad entries.

Click Services tab.
Put checkmark in Hide all Microsoft services
Click Disable all.

Click OK.
Restart computer in Normal Mode.

NOTE. If you use different firewall, than Windows firewall, turn Windows firewall on, just for this test, since your regular firewall won't be running.
If you use Windows firewall, you're fine.

Same problem?

Hi, and thanks for helping out. Disabling those processes from the startup fixed it.
How do I know which one of those is causing the problem?
Thanks again!

Cool
Now, you need to go back to "msconfig" and start enabling services and startups, which you previously disabled, BUT one-by-one, restarting computer each time until you'll find the culprit.
I realize, it's a pain and time consuming, but it's the only way to find out.

Ok great. All of a sudden I have plans for tonight!
Thank's a lot

Good luck

Hi. I've disabled every service on startup in msconfig, but this keeps happening. I would be certain that it's a hardware problem if this happened in safe mode too, but it doesn't.
Any ideas?

Disable "Restart on error" feature...

1. Right-click My Computer, and then click Properties.
2. Click the Advanced tab (Vista: click Advanced system settings).
3. Under Startup and Recovery, click Settings to open the Startup and Recovery dialog box.
4. Clear the Automatically restart check box, and click OK the necessary number of times.
5. Restart your computer for the settings to take effect.

You may see some error message. If so, post back what it says.

Hi, I did what you told me to but my pc just shuts down without showing any screens.
It's driving me insane!

I have to admit, I'm little bit confused.
First, you said:

Disabling those processes from the startup fixed it.

Then, little bit later:

I've disabled every service on startup in msconfig, but this keeps happening

[don_haedo]

Yes, that's exactly how it happened. At that time it had stopped. I remember disabling them, shutting down, turning on and it appeared to be solved. I went to sleep that night, turned it on the next morning, and there it was again.
Sorry, I know this is confusing. I'd say it's a power or motherboard problem but it works perfectly in safe mode so I'm totally clueless.
Note: I changed my IPS a few days ago and everything worked perfectly until then.
I was using a wireless net adapter and now It's a VoIP modem. I noticed that if I unplug the utp cable from the lan adapter (I've disabled the lan from bios), it shuts down considerably less; only once in the loading process and then it stays on.

Looking again through this thread, especially at this:

I need three of four attempts in order to get it going

it may be power supply issue.
With power supply failing, it's very possible, your computer will start fine in safe mode, but not in normal mode.
Unless...your computer is infected. It could create similar issue.

[don_haedo]

I've been having some malware problems lately but RPMcMurphy (a really cool guy from the malware staff) helped me solve them. We finally ran some tests and they came out clean so I guess the computer isn't infected.
I'll have the motherboard checked or replaced.
Thanks a lot for the help, you can close this thread.
