Windows 7: Unknown Hardware problem. Desktop won't POST properly.

Hello once again Sevenforums.

For the last few days, i have had a rather frustrating problem with my system. It doesnt want to POST.
Let me explain this; Turning the computer on is a mystery. The initial startup seems pretty standard, except that there is no beep, Fans run at 100%speed for a few seconds, and nothing appears on the screen. If i then turn it off via the ON/OFF button, and start the system anew, it will first turn on for a second, then go off again. Waiting 4-5 seconds, the System "magically" starts itself up, with the same symptoms as mentined before.

This all has happened after a recent LAN party, where a power shortage apparently may have been the sinner. Just mentioning, i am writing this using that system, as it can still BOOT using a few primitive measures. Removing the source of power to the computer ( by first removing the power cable, and then turning off the outlet before re-inserting it ) and consecutively turning it on, it will 50% of the time POST and start up as usual.



One thing to note also, is that recently, every time i have / have been opted to save a file on my local hard drive, the system has made a loud BEEPing noise similar to the one coming at the strtup.

Sounds like you have a hardware issue. I've had RAM cause an issue that sounds just like that. You won't hear beep codes everytime there is a problem. Considering you said that you had a power outage not too long ago then I would suggest looking into your hardware.

If you have multiple sticks try swapping them out. Same thing with your GPU and hope your PSU didn't burn up.

I tried removing the ram sticks and tesing the system without, with 1 and with the other.
No changes to the startup behaviour.

Just today, i also had another problem. The image on my screen went black, and the screen reacted, as were it not connected to anything. i have double checked my cable, and its working fine.
