I have a weird problem with what i thought was my graphics card overheating. I have a 9800pro and have recently put in my old fx5200 to be sure it was my graphics card causing it. The problem still occured with my old fx5200. I have caught a screenshot of it to show you guys. http://img474.imageshack.us/img474/9008/t9ua.jpg

What exactly is the problem on the screenshot? Matt matt@webgrafix.co.uk

The black writing and grey on the start button. This is the only screenshot i have of the problem. It happens in all programs after a few hours of use. My browser will only show one font. I will get a screenshot of firefox when it next happens. Any ideas what it might be?

I doubt it's the video card...more likely it's a software problem or infection (virus or spyware).

I'm thinking at the moment it's either CPU usage or memory usage. How can i lower these? Or am i just being stupid?

You certainly have a lot of icons next to your clock...that means you have a lot of programs loading at startup. Do you need them all to load, or can they be started manually on an "as needed" basis? Do you do a lot of P2P downloading? Have you scanned for spyware lately? You should have Spybot, Ad-Aware, & SpywareBlaster installed & updated, & you should run them regularly (from safe mode). You should also have CCleaner & run that daily, not to mention regular virus scans & defrags. Have you run MSCONFIG & checked for questionable startup entries? http://www.filehippo.com/

I had experienced somthing smilar when I enabled full AA and AF. Using 2xQucicknux antialiasing on the nvidia card caused the font to blur out quite a bit even on normal desktop usage. Try setting your driver settings to default and check if it makes any difference. Sarosh
