755A My PC worked until 4pm this afternoon, when I power the unit on now it takes forever to post and detect any drives unable to access the bios, but once drives are detected they are set up properly, it was working fine since I built it 3 weeks ago. Any suggestions?

I don't think it's corrupt bios, maybe a virus or malware.
But if you can go to the computers maker website and download bios and install them the way they tell you to install them.

Download the latest BIOS update from your computer manufacturer's website onto a USB flash drive. Refer to your user manual to obtain the manufacturer's website address.

If the downloaded BIOS file is a zip archive, unzip the contents onto your USB flash drive.

Jumper settings may need to be reconfigured on some motherboards to enter BIOS recovery mode. Most Intel-based motherboards have a jumper setting or switch near the on-board

CMOS battery.

The procedure for setting the jumpers will vary depending on your motherboard make and model, so refer to the motherboard documentation for specific instructions.

Power on the computer and press "F2" to access the Setup Mode menu.

If you are unable to access the setup menu, you will not be able to proceed with this repair. Take your computer to a repair shop, as the motherboard may need to be replaced.

Use the arrow key to select "Boot Priority" or a similarly named field. Press the "Enter" key.

Scroll down until "First boot priority" or "First boot drive" is selected and press "Enter."

Select the USB flash drive as the first boot priority device. Press the "F10" key to save this setting and exit from the setup menu.

Connect the USB flash drive to an open USB port on your computer.

Then let your computer fully reboot.

The USB flash drive should be detected and the BIOS should update automatically.

When the update is complete, you may be prompted to restart your computer, or it may reboot automatically.

If you are able to use your computer without any further problems of overheating or failure to recognize drives, your failed BIOS update has been resolved.

hope this helps

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

Hard drive is not detected. Change the Boot sequence in BIOS

1. To access the BIOS you must tap F2 or delete key upon turning the computer on
2. Try to look for the Hard drive if it is detected by BIOS if not got to step 6
3. Look for Boot Sequence or anything that is associated Boot
4. The Order boot of must be 1st: DVD Drive, 2nd: Hard drive, 3rd: Network etc.
5. Save the changes and Restart
6. 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
7. If Step 6 did not work I think you need to replace the Hard drive

Thanks for Choosing

1. You shouldn't need a driver for the hard drive
the Bios ( Basic Input/output system ).
2. You mother board should detect the driver
3. You will have to go into the BIOS setup to see of your hard drive is detect then set the BIOS to boot from the hard drive
4. If your pc takes SATA ( Serial advance technology attachment) then a IDE ( Intelligent drive electronics) will not work with the system without an adapter.
5. Your PC mother board instruction manual will have instruction on hard to access your BIOS settings
Caution: Any changes in the BIOS will not allow some devices attached to your PC to work properly is not properly addressed in the BIOS setup.

is that before or after your bios posts

if after, it could be a bad hard drive (sitting waiting to boot from it, but unable to or taking forever)

if before, well, enjoy your new laptop you get to replace this one

try to install with other sytems and check the data cable

the above assumes IDE drives...

POST ( Power On Self Test ) will take place even with a faulty drive.. it will (should) warn that either no drives detected or drive is faulty.

Rather unplug all deviced not needed and leave only screen and keyboard.

Inside the machine unplug everything except you hard drive, unpleg DVD,CD,Stiffy drives.

Also if you have an onboard graphics on your motherboard then remove the grpahics card you have as well.

Also remove all but 1 of the RAM modules.

If the PC boots now gr8.. you may just have had a bad connection. Now reinsert the RAM modules you have removed. Then start the PC again.

If your PC doesnt boot you may have a faulty/damaged Power supply, motherboard or CPU

Keep plugging back all the components one by one untill they either all are back in and everything works ( bad connec5ion the cause then) or until you get to a point where you attach/plug something in and it doesnt boot...that component is your culprit. And remember it can be anything, from RAM to your mouse..

just no other solution except upgrading BIOS properly

try replacing ram
