Dell Optiplex GX280 boot problem

I have a Dell Optiplex GX280 that is having startup issues. It appearsto be a thermal issue as the fan comes on mostly at full speed and make a whirling sound on switching and does not boot.

    hey , i have exactly the same problem. The first time it happened i turned it off, and when i turned it on again it worked fine. Turned it off and the next day it did the same thing. Only each time i turn it of i have to try to turn it on more times untill it actually works. So the system isnt completely fried. There is something stopping it from booting and its getting more and more damaged. Dunno what it is. Ive replaced the cmos battery. Any solutions?

    My Gateway GM5088 has been flaky on booting up after being turned off. After about 15 months of use, it stopped rebooting on first try, then it took many attempts and NEVER rebooted when Microsoft downloaded an update that required a software reboot. Last week, after the computer was off for two weeks, it would not start at all.



    In the past, when startup failed, the main system fan would not spin. Now, if I turn the system on, the main system fan runs continuously at high speed. In either case, the boot fails without recognizing the monitor, the keyboard, or the mouse. The startup test seems to spin both optical drives, and I believe the hard drive spins, too.



    Most of what I've seen on various sites on the Internet suggest the problem is not all that rare. Blame is usually placed on the motherboard or the power supply, but some people who replaced both have had no success in fixing the problem. The CMOS data corruption, and perhaps the small lithium clock/cmos/bios battery are also possibilities. Is a puzzlement...

I just repaired two Gateway systems with similar behavior (turn on power, fan runs at full speed, no boot), and both needed replacement system boards. (These were a different model, but the symptoms are typical of a dead system board.) I got the boards from a company called Blue Raven Technology (www.blueraven.com).

Before deciding the main board is bad, try another power supply to make sure that's not the problem. Also you might try clearing the CMOS memory on the system board (either by moving a jumper usually found near the backup battery, or by removing the battery itself). Sometimes corrupted CMOS data will keep the system from booting.

HI If your sysem completes the start up and runs normally then obviously nothing is wrong! Some PC's always startwith the fan on high speed, a little like auto-chooke on a car

Sounds like a classic case of overheating. Check the thermal compound under the heatsinks and replace it with Arctic silver 5

May be a cpu problem. Make sure the fan is on the cpu and that it is running. If the fan is running you may need to change the thermal compound that is between the cpu and heat sink. If that doesn't work , the next step would be to try to use another cpu that you know is good and see if it fixes your problem.

Dell optiplex gx280 makes loud fan sound at startup and enters windows screen, but will not finish booting and freezes up.


You may have a problem with your power supply(the loud fan noise) and eventually it may get too hot and will cause problems like not fully booting.

the problem description is
Ithr
Smm mode is initializing the thermal probes.

problably the system is running at high temperature because of improper fan speed, so try to clear the nvram if its not working flash the bios if still the issue persists, replace the heatsink assembly and the motherbord.

Dell Optiplex gx280 shuts down and orange power light blinks


It happens because the power supply is overheats and computer goes to standby. The power supply is 160w or lower. Specially it will happen if you put more devices in such as video card or sound card. So the only solution you have is to place a small 1or2 fans toward the power supply to make it cooler. And 1 more thing the power for the fans should come from other sources.
