Today, I noticed my computer was having some random crashes during regular and non-intensive tasks, so I figured it was overheating and needed its usual dusting out.
I utilized a small paint brush after grounding myself, and carefully went over the fan-blades as I usually have. I then put the case back together, took the PC back to the room it was in, plugged it in - and lo & behold, it will not power on at all.
Regretfully, I can't even turn it on to run my favorite CPU-z and give the computer specifics to you.
Off-hand: It's an Intel Quad-Core at about 2.93 GHz, 4GB of DDR2 Ram, an NVidia 9800 GT 1GB graphic card, has a 550 Watt power-supply (hasn't been an issue, so I don't think a faulty PSU is the problem - though who knows).
I've gone over and made sure everything inside is nice and tightly plugged in/secure to no avail. I apologize I'm not able to give more specific information, barely able to post this from a cousin's Nintendo Wii, haha.
Any advice or possibilities you can offer would be greatly appreciated. Thanks again.
