I run a Dell Vostro 220 with windows Xp 32-bit. I have a nvidia GeForce GT 430.
Recently when using my dell desktop, i have been playing games. After either a period of minutes or hours my desktop will spontaneously go into power saving mode. I cannot exit from this mode by pressing keys or by pressing the monitor on or off again. However on this mode, i can hear sound. I noticed this a couple of weeks ago and have had this desktop for about 5 years.
I have tried to look online at solutions but they never seemed to solve the error. The solutions i tried to do where these:
- Dust insides, this had no effect on my PC
- Check the monitor to see if power cable loose
- I have also checked to see if my graphics card is exceedingly hot but it operates under what it should.
Generally these errors occur on games that are more demanding of your graphics card. I have had no problems other than when i have been playing games for the desktop. I have exhausted all possible solutions and it would seem that it isn't a hardware problem and i was wondering if any of you may have a solution to this annoying problem.
"Power save" means simply that your desktop is not sending any video signal to the monitor. So your video card may be bad. One thing I have found from personal experience is that the tiny cooling fan on the video card can sometimes get dusty and cause the whole thing to blank out. So check that. These things are very fragile so dust with care using one of those compressed gas cans.
If that doesn't help, my recommendation would be to upgrade the card.
