Computer keeps shutting down (serious error message)

[Speshul_K]

My computer keeps spontaneously freezing up. The screen goes white or blue with coloured horizontal lines on it. I have to restart and when i do an error message comes up saying that my computer has recovered from a serious error. It does this every few hours.

The only things that have changed on my computer since this started are as follows:
I had some viruses and such that I totally cleaned using the procedures and help of someone in the Viruses and Nasties forum. My HJT log and Ewido log show that my computer is now clean so I don't think it relates to that.
I installed a new wireless mouse and keyboard and forgot to uninstall the old one first. I have now uninstalled the old one.
I installed and have been using Mozilla Firefox but have since quit using it as the pages freeze up after a period of time.

Help?!

Scan your computer for viruses: http://housecall.trendmicro.com/

In the case that your browser cannot be opened long enough to perform the scan due to freezing, please install and fully update a version of antivirus.

While you're at it, download, update, and run both:

Adaware:http://www.download.com/Ad-Aware-SE-Personal-Edition/3000-8022_4-10045910.html?part=dl-ad-aware&subj=dl&tag=top5
&
Spybot: http://kujoe.com/freeware/spybot.php

The bars on your screen are related to your video card/driver. If a virus/Adware/Spyware/or malware is affecting this, then the above tools should prevent future problems. However, the problem may not be infection related and it is then necessary to re-install your video drivers from the OEM; don't use Microsoft plug & play.

I see you had problems requiring hijackthis. Spyware/Adware/malware are very vicious sometimes. So, in fact, that sometimes they are impossible to remove safely. I'm not sure if you're advanced enough to backup, format, and re-install windows, but for the trouble you're going through, it may just be worth it.

I have already done all of those things (except the video card thing because I don't know how) but since I last posted it would seem that it only shuts down when I use Mozilla Firefox. I guess I'll just quit using it.

I installed VISTA on my HP Windows XP. When I try to run the Intel to check for my drivers it goes to a blue schreen with white horizontal lines and shuts down. I tried this several times.

I installed Windows 7 on my Gateway and I have sound on everything except Youtube and some things on Internet Explorer 8.
