Translation: Why can't I change my screen resolution? (English). You video adaptor limits the resolution you can choose. If you right click on the desktop you can pick the graphic settings you want and it will give you 15 seconds to see what it looks like, before it restores to what it is already.

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.

Hi Two most likely causes for this error are First: the memory module, DIMM3 has worked its way loose and needs to be reseated firmly in its slot with both catches firmly engaged. Second: The memory module DIMM 3 has become faulty and needs to replaced. If reseating the DIMM doesn't work try swapping slots with a module of the same size in a different slot and see if the fault follows the module or goes away. If the fault follows the module, eg to DIMM 1, then it is most likely that the module is faulty. Hope this is helpful, if so would you please register that with Fixya Cheers

It sounds to me like you lost the computer power supply. They cam be purchased at a Best Buy or on Ebay. Make sure you get one with the corredt connections. Draw a diagram of where everything plugs into prior to disconnecting it, and take it along with you. Hope this helps.

PXE == Pre Execution Environment Your computer can "boot" from various devices: * floppy-disk * CD-ROM * USB memory stick * DVD drive * hard-drive * over the network If you don't have a "network boot server" somewhere on your network, you will get that "boot failed" message. Enter BIOS SETUP mode, and disable "PXE boot over network", and make sure that the hard-drive and/or the CD/DVD drives are listed as candidates to be eligible boot-devices.

I know this sounds stupid but make sure the monitor is plugged in and turned on. If it is then either your monitor is bad, or your graphics card is bad, if you have access to a different monitor hook it up, if it works you know it\'s not your graphics card, if it doesn\'t then it\'s probably the graphics card

BIOS or login screen password? if login what windows Version?

An Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Remove the main battery and try again, no change! remove the ram memory one at a time, testing as you go making sure there is one ram stick in the slot at all times. If none of these work, the motherboard is the likely problem and you will need a technician to access.

Most of the Dell desktops have a set of 4 lights mainly in the back of the computer where the ports are (usb). In this model i am not sure where they are, but these lights indicate a problem with e.g memory, hard disk, graphics controller, etc. Also see if the lights in front of the computer show some activity. According to your experience you can remove the cover to get inside and remove the memory first and turn the pc on. if you don't see anything at all or hear some beeps you might need to replace the memory. This pc should be taken to a technician.

Slide the side cover off and look for a quarter and remove it get number and put in a new one.

It is likely a wire hitting the cooling fan. If you open the case and look withing it will be fairly obvious. Otherwise, sometimes clicking noises can come from the CD tray, or the hard drive. If the hard drive is grinding, (and that would be more of a grinding noise) you would be wise to back data up, as that can mean your hard drive is on its way out.

Is there a specific error message? In any case, you may need to boot from the original CD and choose "repair"

Try starting your computer in Safe Mode To do that Turn off your computer then turn it back on and immediately press and tap the F8 key on the keyboard even though there's no display yet on the screen the one that will appear on the screen should be "Windows Advanced Boot Options" and safe mode is there you just need to choose it by the arrow keys on the keyboard then once you selected it just press enter you computer will go to Safe Mode
