Question about Dell OptiPlex GX280 PC Desktop
Ok Cross71 maybe you can help me out, I recieved advice to purchase a new moterboard. I did so and installed it. I know little about this kind of stuff so i just installed it the same way it was on the old motherboard. turned it on and still have the same problem (Amber light on front amber on motherboard) So i recieved advice to check power supply by running a jumper, Did so and I am lost from here because i do not know what the hard drive is. This was supposed to kick on when i ran the jumper. How do I know.
COMP FROZE UP THE OTHER DAY AND I POWERED IT OFF. WHEN I REBOOTED IT CAME UP FINE BUT THE MOUSE AND KEYBOARD DIDN'T WORK AT ALL. SHUT IT DOWN AGAIN AND WHEN I TURNED IT BACK ON IT SOUNDED LIKE A 747 LANDING (CPU FAN) WAS SPINNING UNGODLY FAST. FAN IN PSU IS WORKING AS WELL. I SWITCHED OUT BOTH THE PSU AND THE CPU FAN INTO ANOTHER COMPUTER IN THE OFFICE THAT WORKED (EXACT SAME MODEL) AND FOR A SECOND THE FAN ROARED AND THEN ALL WAS WELL SO I'M ASSUMING NEITHER OF THESE ITEMS ARE THE PROBLEM. WHEN I BOOT I GET FAN NOISE, POWER BUTTON STAYS AMBER, LIGHT ON MOTHER BOARD IS AMBER (IS IT SUPPOSED TO BE GREEN?) WHEN I UNPLUGGED THE PSU THE CPU FAN RETURNED TO NORMAL VELOCITY. DON'T HEAR HARD DRIVE, MONITOR IS BLACK AND SAID IT'S NOT RECEIVING ANY SIGNAL AND GOES AMBER AS WELL - COMP IS 4 YRS OLD AND HAS WORKED FINE UNTIL THE OTHER DALY. THIS IS MY WORK COMP AND I CAN'T ACCESS ANYTHING, THEREFORE I CAN'T DO ANY WORK AT ALL - ANY ADVICE???
take the PSU (Power Supply Unit) from a known working computer, preferable to be the same model and test with it. when you do so make sure you disconnect any peripherals e.g ( Printer, CD-ROM, Floppy).
Look closely at the memory bay for any bent pins, and test with one memory at the time.
Let me know if this is still an issue.
