I have had this problem for a while now. I have tried an new video card and a new monitor to resolve this with no sucess.  has anyone else had this problem?

fifer1791 ...... Perhaps you might like to explain in detail exactly what is happening..... for example, what do you mean by "frequent monitor resets"?

How long has this been an issue?

What operating system are you using ?

Do you have all the applicable service packs and updates installed ?

I am running XP and my pc checks for updates regularly, every morning at 3 am.  This problem has been happening for a year or so.  The PC is about 5 years old now.  The PC is mostly used for the internet so I don't run any power hungry programs.

What I call a reset is when the relays in the monitor or what sounds like a relay clicks a couple of times, usually twice while the screen is blank and the display comes back.The screen also freezes and locks up. Sometimes it resets on it own. Other times I have to go to the task manager which initiates a reset (ctrl alt del)  I also get some display problems.  Sometime a screen won't completley clear when I close a window and I  will be left with traces on the screen. 

I even tried the minimum resolution and set the refresh frequency at 60 HZ
I am wondering if it is a heat issue?  then again I have tried cooling the PC with a 14 " fan and no difference. I know that computers are quite cheap for what I requre but I am frustrated that I can't pin point the problem.

Reset the refresh rate to 75...

Do you have another monitor you can borrow for a few days to determine whether it's the monitor or the video card that is causing the trouble ? ?

I purchased a new LCD monitor thinkibg this was the problem.  No luck, same problem.

So am I, anything special about your environment?

What are your motherboard and videocard temperatures?

Were these both LCD monitors? Does the same one come from the same vendor and is it part of the same series?

What kind of Internet security is installed? What videocard drivers are you using?

Smells like a failing power supply.
I would suggest you D/L and run a free monitoring app like SpeedFan and post the power outputs.

The D/L "button" is in the second paragraph.
