Hello!
Specs:
CPU - i7 940 @ 2.93 GHz
MOBO - asus p6t7
GPU - evga gtx 580
cooler - H80 corsair
PSU - antec earthwatts 500w
RAM - 64 GB
4 TB HDD
So, today I decided to clean the inside of my PC since there was a lot of dust in there. I started off by opening up the case and using a low powered leaf blower. A LOT of dust came out immediately, and I made sure not to physically touch the end of the leaf blower to any parts of my PC in order not to risk any electric failure. I also held down the fans with my free hand in order not to cause overspinning of the fans. After using the leaf blower, I disconnected my 6 and 8-pin power connectors from my GPU and took out the GPU from the case. I opened it up and dusted the heatsink with a can of compressed air. (I know that this voids warranty, but I have done this on numerous occasions in the past without any problems). After dusting my GPU heatsink and GPU fan, I put the cover back on it again and put the screws on. Lastly, I decided to replace the 7 year old thermal paste on my CPU with some of the thermal paste that I bought (I got the thermal grizzly kryonaut). I have done this process in the past, albeit on several other computers. After dusting around the CPU and applying fresh thermal paste on the clean CPU surface, I put everything back together and powered on my PC.
This is when I knew something was wrong. Every time I powered on my PC prior to today, my PC cooler radiator fans would run at 100% power for around 1-2 seconds before quickly dropping to 20% power or so. Then I would see the windows logo and my PC would boot normally. My keyboard also has this annoying blue light that turns on automatically by itself every time I boot on the PC. But today, after I pressed the power button, my fans jumped up to 100% power and stayed at that speed. My keyboard light didn't turn on and my monitor only shows the message "dvi no input signal".
Things that I tried doing:
- I double checked that I put my CPU back into its socket correctly. I made sure the corner arrow of the CPU is aligned with the arrow on the mobo socket.
- I checked my CPU radiator fans, my GPU fan, and my PSU fan and all of them are spinning.
- I checked that all wires are connected and are securely in place.
- I tried putting my my dual link dvi cable into the 2nd port of my evga gtx 580, but I still get the dark screen and the same message.
- I randomly noticed that my 8-pin power connector to my GPU has 1 missing pin in the corner. I don't know whether it fell out today during the cleaning process or it's supposed to be missing, but my GPU is powered on and it is getting enough power to have its fan spinning, so I think it's not that big of a deal?
- I reseated my RAM sticks, even taking all of them out with the exception of only one.
*Take note that my GPU has been "acting up" for several years now with occasional overheating and crashing (my screen would randomly go black, I would put my hand to feel how much air is coming out from the back of my GPU only to find out that the fan stopped working entirely). However, after installing MSI afterburner and setting my own fan curves, my GPU now idles at 51*C and runs at around 67-75*C under load. My GPU fan runs at 85% speed under high load, which is the maximum speed it can go to. On the other hand, my CPU has been running flawlessly for the past 8 years or so under cool temperatures (35-40*C).
Any help would be appreciated in figuring out what could be causing this. Could it be the motherboard going faulty after the dusting?
