Possibly it is overheating, which would depend on how often it runs, and how fast. During startup, it is normal for a fan to run at high speed, but if it's on constantly in sleep mode, I would look towards an overheating problem. Open it up, check for, and clean any dust around the heatsink / fan, and power supply fan. Also make sure that outside the PC there is plenty of space to allow airflow.

Try hitting F8 key to access the windows boot menu, Choose safe mode. If you can not get in to windows that way, you will need to reinstall windows.

Problem on Dell OptiPlex 780 Desktop


You are going to need to start your computer in safe mode and find the XP drivers that will work for your motherboard manually from the web (Assuming that there are any created for XP for that board)..

That blue screen you keep getting is because you don't have the correct driver loaded for something on the motherboard that it needs to boot correctly and your XP install couldn't find it on the web to install automatically.

Start your PC and press F8 several times until the boot menu comes up. Then select "Safe Mode with Networking".

Now start looking for your drivers here:

I have a Dell Optiplex 780 and when I am logged in and walk away for 15 or more minutes it will go to sleep, I will then come back wake it up, log in and the screen will go black and I cannot get in unless...


This problem is ongoing because you have it configured to sleep turn the sleep mode off. What it is doing is attempting to load drivers again and not saving to cache when in sleep mode you may have not enough storage allotted for the sleep mode to save information go and increase the storage memory to store the data so that when it sleeps it can store the data and wake up with your screen as it was when you left it.
Personally I do not use sleep mode never have, never will. It is nothing but a problem for me anyway. I always keep my machines running with the exception of a lap top. So my suggestion is turn sleep mode off. I also log out and then log back in same principal really. Or just close the machine totally power it down. Sleep mode was a wonderful concept along with shutting down hard discs etc. However you will often times be more into a hassle than just leaving it on or shutting it down. Less work for a computer is better just my humble opinion.
Last but not least, my last resort would be to re-install operating system again once I start getting to many things going wrong with my machines I do them over solving all sorts of problems that are behind the scenes that take hours sometimes to repair individually. This would be after you retrieve your lost files from the drive. John
