Hello,

I have a Vista laptop which is 2 years old. It's never gone through any extremely serious problems where I've had to reformat everything, but this week, it started to act weird. Occasionally, my laptop screen would blank when it turns on. It's black like the blank screensaver, but no matter what I do, it stays blank. I know the audio is still there because the windows startup noises still go off. Very recently, it started to go blank if I use a lot of CPU, such as running a game and firefox and music. I've never had this problem before, and I don't know where to start tackling it, so I'll include my hijackthis report for starts:

I'm not sure if it's a virus or if its a hardware problem. I recently took out the battery to my laptop, having it powered by the cable only instead. I heard this saves the battery life. I doubt this is related, but I'll provide all info just in case.

Thanks,
Jerry

It looks like Mcafee or something might have detected and removed a trojan, the evidence being:

O2 - BHO: (no name) - {5C255C8A-E604-49b4-9D64-90988571CECB} - (no file)

The trojan may have done some system file damage. I therefore recommend two steps:

1/
Download and run anti-malware bytes from the below URL. This will clean out any remnants of malware.

http://www.malwarebytes.org/mbam-download.php

2/
Either re-install your video drivers from Control Panel/Device manager or if that doesn't work, repair your Windows from the recovery console or whatever tools HP provide for this purpose. You won't lose data but back it up in any case because you don't know what the Trojan's done. McAfee in theory should have stopped it from doing anything.

The above advice is based on an assumption that the problem is trojan related. It could be hardware but we can consider that after the evidfential side has been dealt with.

Let us know.

Hello guys very useful reply from u guys it was very informative.

Webshop system

Thanks Suspishio

I've just ran the scan, and it didn't show any malicious files. I'm going to go through the list of video drivers from the HP website and reinstall them. I will let know you when I finish that.

I'm sure Suspishio will be please you approve !
and no im not going to click on the link in your signature !lol

Too kind.

Anyway, that damn sig website is all in Danish - so of limited use to our forum members!

Maybe rajuguru really meant it. In which case, thanks. LOL.

Even though, those spyware cleaning programs didnt seem to find any bugs, the problem seems to be fixed. I never get the blackouts anymore. Thanks Suspishio!

You're welcome. Do please mark this thread as SOLVED.
