Almost a year ago I replaced my graphics card with a ATI Radeon HD 3400. All was well until a couple of weeks ago when my screen shut down - not the pc that kept on working. Tried all sorts of things, fiddled changed leads, re started several times and although I could hear windows music no screen. Gave up, made coffee, went back two hours later and all well again except I am almost certain that the screen resolution was slightly different but not sure.

Sorry to go on but the same thing happened again today. The screen is now working except it has a flicker. Checked monitor by plugging into laptop and all is fine. Could it be the graphics card or maybe the psu.
Any ideas please.

Right-click on Desktop then go to Properties>Settings check your Resolution, then click on Advanced>Monitor and check Screen refresh rate is 60 Hertz.

Have you tried the Auto-Adjustment function button on the monitor?

Thanks for the replies. Refresh rate is already 60 Herts but will investigate auto adjustment function.
I know you are not going to believe this but when I just switched on my pc my homepage has changed all by itself - from google to jeeves !!

That can happen if you use IE

Download SpywareBlaster and keep it updated

"Removal" approach after your system is already infected.

SpywareBlaster effectively prevents ActiveX-based spyware, dialers, browser-hijackers and
other Malware or potentially unwanted programs from ever installing on your system in the first
place.

Go there is an option to tick, which will stop your home page from being hijackers

The screen flicker has been getting worse so early this morning I again did a google trying to solve the problem but all of a sudden the flickering stopped. Switched off pc and now back on line and of course the screen flicker has returned.
Has anyone had this experience.....

It look like the display card is the problem

Try unseating and reseating the graphics card in its slot.

Still no luck but thanks for the idea.
