Windows Freezes on windows logo

Hello,

I have a very strange problem with my client's computer. It's Acer netbook. I will explain in steps and what I did so far.

I had Windows XP installed.

When booting, I see motherboard splash screen , I can press F1 or F12 if I need to, but if I choose boot from drive (default) I just get a black screen.

I am able to a acces BIOS if I need to.

1. Hard Drive? I used Hirens CD to boot from. It does boot up. When I choose to load Mini XP, it starts loading and freezes when I see Windows Logo screen. Progress bar doesn't even start to move. Exactly the same problem if I use ERD Commander for Windows XP.

I think it is safe to assume that this is not the Hard Drive? I even disconnected hard drive completely. I believe, I should be able to load mini XP or ERD without hard drive.

2. Memory? Computer had 1 chip: 1GB. I ran Memory86 test. Test passes with flying colors. Other tests on Hiren's CD work, so I tested CPU, Video memory, etc ... all pass.

3. I've reset BIOS Settings to default. It did not help. (Also installed a new one)

I am thinking it can be motherboard or CPU, but I can load some DOS programs. I even ran some DOS test program for video, it passes fine.

Any ideas? What else can I try? If it is motherboard or CPU, how can I test it to be certain?

 

If your able to run Safe mode start bye running all Virus scans
