Possible that it's caused by a faulty hardware or a computer virus on your computer. For us to isolate the issue we must start troubleshooting with the hardware

1. Remove all the connection at the back of your computer
2. Power cycle your computer tower by pressing the power button for 15 seconds
3. Plug the power cord back in and monitor cable at the back of your computer tower (if it turned on, meaning that one of the device plugged at the back of your computer is the one's causing the problem, for you to pin point the problem, try plugging it one-by-one and turn on the computer each time you plug a device)
4. If it keeps on doing that, open up your computer tower (be careful to unplug the power cord and power cycle it to avoid static electricity)
5. Reseat the video card, turn on the computer again, if it's still occurring
6. Reseat the IDE/Sata cable of your hard drive and try to make sure it's properly plugged in, turn on the computer again, if it's still occurring
7. Reseat the memory, turn on the computer and test it again if the same thing
8. If you have 2 memory chip inserted in your computer tower memory slot, remove the other one and turn on the computer, do the same thing to other memory and each slot
9. If all else fails, restart the computer and keep on pressing F8 before the window welcome screen comes up - to go to advanced boot options
10. Boot to Safemode
11. If you are able to boot to Safemode
12. Login as administrator
13. Click start
14. run
15. type msconfig then press enter
16. click on startup tab and click on disable all button at the bottom part
17. Restart the computer and let it start normally
18. if the same thing happen, boot to safemode again
19. Login to administrator again
20. Right click my computer
21. Click on properties
22. Click on Advanced Tab
23. Click on settings button under Startup and Failure
24. Uncheck the Automatically restart under System failure
25. Restart the computer in normal mode
26. Tell us if you see any blue screen error, if so, post the error here

if all else fail, your operating system needed to be reinstalled and you should have the cd for the operating system if it's XP or Vista or Windows 7.

Where does a dial up modem go in a Dell optiplex 760?


The dial-up modem would install inside the computer in a PCI slot. VERY easy to install but a couple considerations before doing so... There are different sizes depending on whether the OptiPlex is a mini-tower or small form factor case. Also - you would need drivers for the modem that are compatible with the operating system you have installed on the computer.
