I've got a pc with XP Pro SP3 fully patched.
I use an E8400 cpu, 4 gigs RAM, 1Tb. Western Digital Black hard drive, Corsair HX620 power supply.
Protection for the system comes from a router, Windows XP firewall, Defensewall, Avast Home (free)and Prevx 3.
I don't go to porn sites nor do I do online gaming.
The only game I have on the pc is The Lost Inca Prophecy from Bigfish Games.
This pc has been running without a hitch for about a year.
Last night the pc was working properly.
I shut it down for the night and when I started it up this morning it went to check disc. That passed and the pc started as usual. It's never gone to check disc before.
Then I opened Firefox and the search engine, Google, just showed the words 11th birthday but no Google picture.
Closed the browser and opened it again and it was fine.
Started checking my email in various gmail account and none of them were working properly. I kept getting a pop up box from Google that some of the features were not working and that I could revert to basic text if I wanted.
Live Mail is giving me some problems too.
I closed Firefox and opened it again in Safe Mode but that made no difference.
There are no known viruses or malware on this machine. I keep after it so that I don't have a problem.
The only other info I can think of is that about a week ago I had a loose connection to the motherboard power connector and the pc shut down.
But after I pushed the connector in more firmly I had no furhter trouble.
Please, what's going on with this pc?
I'm still a novice.
