Help, I have a virus

[m1spw]

Twice now over the past few days when on PH my screen has suddenly gone black, then lots of different coloured flashing lights have come up. I am not saying its PH, but I am 99% sure its a virus.

What should I do? I'm currently running:
-black ice defended
-AVG antivirus
-Sygate firewall
-spyware blaster
-spybot search and destroy
-Ad-aware SE personal

None of them are picking up ANY viruses, so I think they might be infected with it so as not to pick anything up (normally I get tracking cookies and the odd virus on scans). I havn't got a clue when it comes to computers, so any help on what to do would be greatly appreciated!

try http://housecall.trendmicro.com/

its an online virus scanner, so it cant actually get infected. only works with internet explorer tho.

the other possibility is that something is over heating on you graphics card. try running the pc without the case sides fitted, and see if that cures it.

Sounds graphics card related....

Check and see if your machine is fully patched (Windows patches) including any optional hardware updates. Also, might be worth having a look in your event viewer just in case any error messages are being logged...

If none of that lot are picking it up, then it's unlikely to be a virus. As has been said, probably hardware related.
