So a few days back, my 5 year old computer was really dusty and I needed to clean it out. I know all the precautions, like make sure you’re not charged with static electricity, use compressed air ect. All I wanted to clean out was the heatsinks, the fans and where the dust mostly settled. I started with the CPU fan/heatsink and blew it with compressed air canister, then moved on with the GPU (And this is were I think I screwed up). I took out the GPU from my mobo and unscrewed the heatsink with the fan, thoroughly cleaned the heatsink with compressed air then I tried taking out the dust around the memory and around the core. I put everything back together, cleaned the rest of the computer and tried operating it again. Everything worked fine as usual, until I tried playing Call of Duty: Modern Warfare 3 and noticed a huge performance drop, I have the same settings and used to have a constant 60 frames per second, now I’m not even getting over 40 frames. I tried other games like Crysis 2 and noticed massive performance drops, from 60 frames to nothing higher than 20 frames! I have my GPU updated to latest driver; 310.70. I tried reseating my GPU, RAM and other components and nothing worked!
Now this is something I should mention: a few days before I started cleaning, I couldn’t properly boot up my computer, everything would run when I press the power button, I could hear all the fans and Harddrive working but the monitor had no signal and my mobo would start beeping after a minute. Everything was plugged in and I managed to fix it by opening up the case and restarting. All my games were running fine, I played Battlefield 3 pretty smoothly. This problem often occurs now after I cleaned up my computer, but differently; after probably 10-15 seconds no signal on the monitor, windows boots up normally, no beeping noise.
My PC specs:
Geforce 9600gt 512mb
2gb RAM DDR2
Intel Core 2 Duo E8400 3.0ghz
Windows 7 Pro 32-bit
I know this hardware is old stuff but for 5 years it has been serving me well.
I have cleaned out my computer before and it worked normally.
I have overclocked my GPU before but I returned its clock speeds back to stock settings.
I haven’t spotted any graphical artifacts or glitches, no crashing or anything.
I don’t reckon my GPU is overheating while playing games, my computer wasn’t beeping from temperature warning.
So please anybody who knows whats going on, please help me :[
