My pc doesnt load every time I want to turn after i boot the power and press 1st, 2nd, 3rd and 4th boot... in the screen I can see Dell is loading but doesnt move, i try to press F12 for boot and the...


Are you Sure that the computer model is Dell Optiplex GX260? Because looking at the manual diagnostic lights are found at the back. and the fault can be determine If the ABCD lights are yellow or green. But None the less 2/3 Depicts a hard drive problem while 3/4 depicts a memory issue.

Hard drive Issue:

1. Disconnect all non essential cables at the back of the computer. Leave only the mouse, monitor and keyboard. See if it boots up normally
2. If it boot up fine. try plugging one peripheral at a time until you find which peripheral causes the computer not to POST (Power on Self Test)
3. If you still getting problems, Follow these steps
4. To access the BIOS you must tap F2 or delete key upon turning the computer on
5. Try to look for the Hard drive if it is detected by BIOS if not got to step 9
6. Look for Boot Sequence or anything that is associated Boot
7. The Order boot of must be 1st: DVD Drive, 2nd: Hard drive, 3rd: Network etc.
8. Save the changes and Restart
9. If you still get the same message I suggest that you take out the hard drive and put it back in until it is detected in BIOS
10. If Step 9 did not work I think you need to replace the Hard drive

Memory Issue:

1. Open the chassis of the computer
2. Try taking out all memory modules
3. Rub the metal contacts of all memory with a pencil eraser
4. If more than one memory. Put one memory first and turn the computer on. If it turned on add another memory and turn the computer on. Repeat these steps until you determine which memory is faulty or all memory module contacts needs cleaning

Compaq Presario S3040SE PC Desktop was working fine. when i turned it on next day screen says operating system not found. restart. now monitor wont kick on and hard drive light doesnt come on. only power...


Normaly when you get the error that the operating system cant be found, it is a indication that the hardrive has either gone bad, or somehow some of the system files got deleted. I would say though since the hard drive light wont come on it could be the hardrive has shut down completely. But you still should see the company image of your computer when you start it up, (the bios screen)

A bad hardrive would be my first guess, 2nd problem if its not your harddrive would be a new power supply.

Had trouble booting the computer over time. Sometimes power light would come on and nothing else. By unplugging, waiting 15sec it would power up. Over time this stopped working. Eventually power light...


Time to look for a new computer. That and take out your hard drive to copy your files over.

Sounds like motherboard problem. Probably not worth repair.

I've got an HP desktop with similar problems. It turned on one day just fine. The next day not. I don't even get the boot up screens. Disconnecting Hard Drive and CD/DVD components do not help. I should at least get some BIOS POST beeps and a Hard Drive Not Found or such. I do not. On occassion it will boot to a blank screen with white cursor in upper left. Most the time no screen at all. On rare occassion it comes right on and boots Windows. I guess it could be the power switch ... but I doubt that.

Only shows compaq on screen


I work with Compaq computers now and usually your problem points to the hard drive. I know Compaq's will stay on that screen if the hard drive has failed. Try another hard drive would be my suggestion.

Hope this helps.
