Dell optiplex GX280 tower machine, pc reboot again and again, fan run so fast and make alot of sound, also power light blink red instead of green, i have changed rams but facing same problem, what sho


Hello here is the home page:

I think you have some kind of a virus or malware on your system.

Install this program and make a full scan:

http://www.malwarebytes.org/products/malwarebytes_free/

You maybe have to start the pc in failsafe mode by pressing F8 while you reboot.

Install also a better FREE antivirus program:

http://www.microsoft.com/en-us/download/details.aspx?id=5201

Please uninstall any other antivirus programs before you install microsoft security essentials. Run a full scan when installed and updated.It`not great to have more than one anti virus program installed. Most antivirus programs have a background scanner running to protect you from virus vhile you surf on the internet open a file etc.With more than one antivirus program the pc`s performance will be decreased.

There are a lot of things that can cause a computer to shut down.This could also be the power supply.Try also to renew the thermal grease between the cpu and the fan but BE CAREFULL not to damage the cpu.
If you are unsuccessfull at resolving the problem visit a computer repair shop.

When you talk about checking memory, it's the physical RAM stick inside the computer. RAM does not have sectors like a hard disk drive. If it does happen to be bad I'd replace it with at least 1GB to 2GB. 512MB is really low.

Good luck

Hi my computer dell gx280 didn't work. It keep show "no boot device available". i try to replace with new hard drive but it still show same thing. Can you help me figure out what is problem with it please?


Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";} To install new version of XP. Insert XP CD into drive, reboot pc pressing F1 button.. This takes you into BIOS, change your primary boot device to CDrom, save changes and reboot. Select boot from CD once this appears and wait for files to be installed. Select the part of the hard drive you wish to use for your operating system (usually the largest) and select partition this drive. Delete any previous os, and reformat hard drive. (Be aware this removes everything saved on your hard drive, so always back up first) Re boot afterwards and reinstall operating system.
Try the above solution and let me know how you get on?

Hd keeps rebooting. I swapped drives, battery, memory and still the same so it must be something with the motherboard. Any suggestion. It's a Dell Optiplex GX280 desktop


It could also be the processor, either its overheating or it has simply packed up first check that the heatsink above it has been correctly installed and is resting directly on top of the processor and that the fan on the heatsink is functioning. If that doesnt work then replace the processor completely.

Dell Optiplex GX280 restarts suddenly? all files closed and . the restart could be after 2,3 minutes of power on. I don't know why its behaving like this?


Hi, sounds like a crash, do you get any report messages after reboot? Try starting in safe mode; press Del button during initial bootup, once in safe mode you can reset to a time before the problem started. Hope this helps, if not come back to me?

Dell gx280 wont run I installed new video card in pci e slot


I had exactly the same problem on my friends Dell GX280. It will only let you use the onboard card or the new radeon card not both together. In the end we had to buy a Radeon card that was made specifically for two monitors and disable the onboard card on BIOS. It would not let us use the two seperate cards in unison.

Dell GX280 will not boot into OP. Keeps looping back to the Safe Mode screen over and over. Anyone know whats up?


This looks like a software or hardware conflict. Try running 'chkdsk' from WinXP setup cd (or Vista's), (after booting, choose option to repair).

If disk check does not help, then you will have to back-up your data manually, format the harddrive, and re-install OS.

Computer keeps restarting


im assuming your computer running windows, does it go inside windows b4 it will restart? common causes regarding this problem are corrupted operating system or over heat on your processor and incompatble softwares such as firewalls and antivirus.
