Hi... thank you so much for taking a look at this.

I am using an Win 7 upgraded laptop. laptop frequently dies on first few seconds of startup. Computer tech I sent laptop to mentioned bios kept getting recorrupted after flashing bios. They took out the CMOS battery.

Ran Advanced System Care and found lots of spyware. It was able to get my spybot immunisation to work completely after running it. I only ran these prog before this problem appeared: Malwarebytes, Spybot, Spyware blaster, threatfire. None detected any serious issues. Windows could not be updated.

I now clean installed to factory settings, reloaded upgrade for Win 7. Laptop still failing to startup consistently. Windows update downloaded but failed to install. Avast anti-virus not starting up, I am now using Microsoft Security Essentials. Reseated Ram modules and tried changing around.

because cmos battery taken out, time resets if no battery or power is attached. Question is, do I have a bios rootkit? Cause I heard it can cause problems even after clean install.

1) No issue with running Defogger and Gmer.

Hi elise,

Thank you for your reply. Unfortunately I was stupid and downloaded some windows updates and ran some programs. Everything seemed fine until my laptop crashed 1 day after on 8 Nov. and cannot be started up.

I am trying to start it up using random methods. If they don't work I will try to get someone to help flash my bios this week as before when it died so it can be started up.

Very sorry.

Flashing your BIOS might not help.

Please let me know at which point your computer crashes.

Do you have a windows CD at hand?

regards, Elise
