This is really puzzling me. I never shut down my PC, when lately I noticed that my monitor goes black on random. Thinking it might have gone into standby ( I DON'T use standby or Hibernate) I try moving the cursor or tapping keys on my keyboard to no avail. I can see that the monitor switch is on and also the switch on the tower. The only way I can get my monitor working is by holding the on/off switch for several seconds and then the PC shuts down. Then I restart my PC. Anyone know a solution for this? Thanks SallyG I'm new and I'm willing to learn and I'll give you advice when it's my turn

Try another graphics card in there for a while, maybe your current one is giving up. Good luck :^) P3-949Mhz 640Mb PC133@146 GeForce4 64Mb PCI 36.5Mhz

I suspect it is going into sleep mode. Try tapping the power switch (do not hold it in, just a firm push and release) that usually wakes it up. Another way of waking it up is by pressing the "Alt" and "Tab" keys together. I assume you tried to move the mouse or press the "Enter" key on the keyboard? as that also sometimes works. Final one to try is go into: Start > Control Panel and Select Power Management Change Power schemes: to be "always on" and Change System Standby: to never. ___________________________________________ ☺ When everything else fails, read the instructions.

As far as the graphics card, I think mine is integrated into my board. Also mosaddique, I changed the setting in my Power management and I'll see how that works out. Thanks, I'll post back if all is ok. My eyes are blue when I think of you My eyes are brown when you are a clown

Thinking about it, I had a PC awhile back that used to hang if it went into sleep - there was a key on my keyboard I'd occassionaly press by accident. Almost as bad as that "windows" key when I'm playing games, lol. P3-949Mhz 640Mb PC133@146 GeForce4 64Mb PCI 36.5Mhz

The thing is, if you read my post at the beginning you can see I don't have anything set to put my PC into sleep or hibernation. That's what's puzzling me. I tried mosaddique's advice by turning my Power schemes to be always on....I had them turned off for almost 2 years. Now, when the monitor goes black I can hit any key on the keyboard and it takes a few seconds, but my monitor comes back on? Strange that this should start after 2 years? Anyone else have any idea as to why my PC goes to sleep? My eyes are blue when I think of you My eyes are brown when you are a clown

Did you change any BIOS settings? Did you add any new hardware? Usually it is one off these that cause these kind of changes. I believe it is something to do with ACPI compatibility. Look here for more information or google for ACPI. ___________________________________________ ☺ When everything else fails, read the instructions.
