1 Answer

Dear Sir, I am first time share my problem in this forum & I hope I will learn much more. I have dell computer minitower gx620. I am using this computer from 2 years, Now problem is, When I connect power cord in to wall socket then automatically power LED goes ON as orange color and CPU cooling fan also automatically goes RUN. If I want to shut off from power button, not possible. Actually, my PC was off from one month. After this period I start my pc then above mention problem occurred then I opened side cover and see some thing. I found some wet area on mother board then confirmed that that was RAT URINE because my pc back side PCI empty slot cover was not available so one rat goes into my pc and drain urine on it. I wash my mother board with good quality contact cleaner and start but now same said problem. Kindly give solution to remove my problem.

Sorry to say but any liquid other than mineral and vegetable oil will permanently damage a motherboard. So the urine may have caused the damage, or the contact cleaner could have. The Orange/Amber lights on Dell systems mean either the RAM is not seated properly which is usually an easy fix, just take them out and put them back in, but if that doesn't work your motherboard is dead, and you will have to inquire dell for a replacement. Good Luck, and thanks for using Fixya as your Go-to source for information.

Optiplex gx620 2 beeps on start up, displaying 123.

If windows 7 you need to burn a repair disc & run it. Go to Maintenance, creat repair disc (use one CD & mark it with Dell gx62 on top, repair disc run first on bottom)
Restart your computer and hold down escape, F1 or F2 to get into the settings in the CMOS. You must chang the boot order of your startup. In CMOS use arrows to right to Boot to change to CD ROM then HDD so your CD will go into repair before starting the HDD. Each CMOS is different but usually you can use the f5 or f6 to change the order and f10 to exit & save the setting. Restart your computer after you put the repair disc in & that should repair your start up.

My screen on my dell gx620 goes off when booting but I can get in in safe mode?


It sounds like you have a corrupted Video Driver. Safe Mode uses defaulted video drivers that are in the operating system and are not specific to your video driver.

Boot into Safe Mode, go into Device Manager and UNINSTALL the video card from the PC (this is removing the info about the video card - DO NOT REMOVE the actual card from the PC).

Go to Control Panel and uninstall any video drivers or programs that are associated with your video card. There are two video card options for your Dell - an ATI and an Intel. If you see any ATI programs, go ahead and uninstall them as they may be corrupted as well.

Reboot the computer normally and it should boot correctly but with a very poor looking display. Go to the dell web site and download the drivers and install them. This step will likely require a reboot.

Sound not produce when audio is played


You do not say if the sound was working before.

You do not say which operating system you are using.

Install the Audio Driver from the Dell Drivers & Utilities CD that came with the computer or download them from here, selecting your operating system:

Sound of my pc removes after 5 mins from installing drivers. my pc is dell GX620

if you have reinstalled corect drivers from the dell website
or the cd that was supplied with it, there shouldnt be a problem.

If your using a operating system that was not made for these cd drivers you could have conflict issues, search for card make and os that you are using now maybe there is update.

Since the card does work for 5 minutes, and then stops it could be a possible short in the wiring to speakers or amps. make suire there is no shortages that can cause the card to over heat and trip out. hope this helps

For this solution I would suggest contacting Dell, or checking Ebay. You may find an Optiplex GX620 on Ebay for parts, that you can buy for a song. (And sing it yourself)

Should a Front panel Cover not be available, (Or too pricey), you may want to look into buying a new computer case.
You can buy a decent, good looking, new computer case, for around $60 to $80
Then transfer your parts to it.
Here are examples,
You might also want to check Ebay for this too.
