    It's the same except the orange light is steady and the Hypercool fan goes like crazy. Nothing else happens.

The Dell GX620 as well as SX270/280 GX280 computers are a few models of many that suffered from Faulty Capacitors on the motherboard which regulate power supply. When they totally fail, about 4-6 of them on the board, the power light will be orange and the system will not post. Other systems also include reaching a BSOD (Blue Screen of Death) before Windows loads, or even random BSODs while running windows.

IF you have decent soldering skills, you can order capacitors from badcaps.net and replace the 2200uF 6.3v caps on the board and the system will start fine.

I have done about 40+ such repairs can confirm with 90% confidence this is the cause of your orange power light and non-booting issues.

An Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, 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.

My Dell gx 280 keeps saving that i'm missing a ntldr, how can I fix this problem


Start the pc with your rescue disc as there is a boot file error. When you get it started, in safe mode, run CHKDSK/F to find the error and attempt to fix it.

Sound problems after reinstallation of windows


Did you install it to the factroy default installation or did you install windows anew? 

You need to install the Dell sound drivers. They're found on the dell home page or on your media that came with the Optiplex. 

Also, check the system control / administtration / hardware section to see if windows potted a problem with the hardware.

Problem withe dell gx280 fan and display


Unfortunately this seems so be a motherboard problem, Dell's solution is to replace the motherboard I'm not sure there's much you can do at home or work to fix this - if it's still under warranty get dell to replace the motherboard if not im afraid its the bin for it sorry
