Question about Dell OptiPlex GX270 PC Desktop
You can overcome many PC problems if you can at least start the PC, whether the problem is due to a bad driver, incorrect monitor settings, flaky hardware, or a troublesome program. In these cases, you may be able to fix the problem by starting Windows in Safe Mode, or by using an emergency boot diskette (see "It's Just Not Normal" or "What To Do When . . . You Need To Create A Boot Disk" in the "See Also:" section below). If that still doesn't solve your problem, keep reading.
Most boot problems are hardware-related. There are many agents that may have contributed to your PC’s apparent demise. There may be external factors that are causing your PC to misbehave that you can rectify quickly. First, check the power supply and all connections. If everything looks to be connected correctly, the next step is to listen to see if your hard drive is spinning but nothing's on. If this is the case, check to make sure your monitor is turned on and/or unplugged. If you still haven't made any progress with your PC, you may have a Hardware hang-up that's a little more serious (such as your CPU, Motherboard, or a number of other items).

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty
One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive
Test all leads that attach to your hard drive including electrical extensions,IDE,SATA
the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they are probably old and faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error
hope this will help
