I've been having a number of issues getting my computer to power on.
The short version is that when I go to power it on, the fans/lights kick on for about 2-5 seconds, and then it powers down and restarts the process again. It will loop like this endlessly unless manually powered down during the breif window when it has power. At no time during this does the monitor react at all (no bios, nothing, it's like the comp is off)
There are a great deal more details though. I have had this issue previously, and replaced my psu at that time to correct it. Interestingly, there was a noticable preformance boost after replacing the psu, and it seemed to work fine for about 2 more months. Gradually though, the problem has returned. A few weeks ago, when restarting the computer it started doing that same 'loop' again, but after a few tries it came on and seemed to work normally. After restarting it today though, it won't get past it.
Additionally, and possibly related, I've had microphone issues in the past with this system, before the first time this restarting issue has occured. A loud buzz when speaking into the microphone, which would go away if the case was touched. I believed this to be a grounding issue, and checked everything I could think to for connection issues, as well as different power outlets, ect. This problem seemed to clear itself up a few weeks before I first had the problems with the restarting.
I'm including specs, however I've seen this same identical issue mentioned online at several different sites with people who have a wide range of hardware.
I'm pretty much down to replacing the motherboard, which isn't a simple option to take when you're a broke college kid. And I absolutly need the system working for school. Any advice that could be offered would be appreciated.

It's not the power button. It's something else.It's dropped so there are a lot of problems inside the computer. Get it serviced. If the technician says that you need a new motherboard, then buy a new computer instead because motherboards are expensive.
Perhaps it is time to change or recalibrate your battery, some of these particular issues, came from a old or faulty battery. other that that, its a motherboard capacitor blown issue, it can hold electricity, but the capacity to do it came to and end.
The things to check when your system will not post are RAM (make sure it is in all the way) Hard Drive (make sure it is properly connected) Your CD/DVD drives (again check connection) and your video connection (if you have onboard graphics, this may not apply, if you have a seperate video card make sure it's properly secured in the PCI slot)
Once you've checked all of these things, if you still have a problem, listen for the beeps that come from your computer's motherboard and remember the order of short and long beeps. Respond with the beep sequence and type of computer you are using.
Without the model number, it is not possible to research this issue. However... My first suspect would be with the software driver. Some system settings do not like to be oscillated too quickly. (I.E.Going in and out of sleep mode for the computer too quickly, or to and from power save for the monitor too rapidly.) This was a problem especially for older versions of windows. (Vista and prior.) Increase power-save to more than 5-10 mins, and check for driver updates. Being that you were able to get it running without unplugging or turning off the monitor, I do not believe it is a monitor issue. (Outside of the RARE possibility of a hardware or firmware conflict between the monitor and video card/chip set.)
On your computer, click Start
Click Control Panel
Select the Dell Printer
Restart your computer
Turn the printer on
Allow the computer to reinstall the device-device for the printer.
Print a test page.
It is probably in "lower power mode". First try hitting enter a couple times and moving the mouse.
If that doesn't do anything try unplugging the power cord for a couple of seconds and plugging it back in.
If neither of those work the next steps will involve opening the computer (only do this if you're familiar enough).
First unplug the PC before all of these steps...
Open the PC and check to be sure the RAM sticks are securely seated.
Try taking the CMOS battery out for a few seconds then putting it back in. The CMOS battery will be onthe motherbard. It is a small silver coin-shaped battery sometimes used in watches and cameras and other gadgets. Be sure to put it back in the same way it was when you took it out.
If none of that worked check to be sure any other components are firmly seated in their slots.
If none of this has worked I would say call dell support to see what they say.
take a volt meter and check the power at the end of the power adapter, sounds like it may be a power issue. if all is ok on that end does it still work on the old system? you may have to hook it back up to a working system and see if there is a firmware upgrade for it. Best of luck
