Hi Linus Tech Tips.
My girlfriend ran into a rather strange error after cleaing out some dust from her PC.
First of all, we tried to fix one of her headphone jacks on the front ot the PC so we had to open it up, and realized it needed some cleaning.
We used a vaccum to get out the large amount of dust collected and a dry whipe of the interiors to get out the really heavy dusted areas.
This included wiping the circuit board of the GPU very gently with a cloth towel (dry).
We cleaned all the fans in a simmilar mannor.
After this, we put everthing back together and the PC started like normal.
However, the preformance had a significant drop, for example, her framerate in League of Legends dropped from a constant 60 to about 15-30 at the same settings as before.
We have tried to find out where the error might have occured so we tried running a video file, and it seems rather slow.
There has also been random shutdowns of her system, either while playing games or just using the computer as normal, they seem random.
We have also tried various benchmarks to try and find where the error might be located with no success yet since every is reporting normal figures.
We dont know what to do, and what we did wrong.
The drivers are all up to date.
Her system specs are as follows:
Windows 7 Home Premium 64bit.
MotherBoard: MSI H55M-ED55 Socket 1156
CPU: Intel i5 760 2.8GHZ
GPU: Geeforce GTS 450
Memory: 8GB Kingston ValueR 1333mhz DDR3
PSU:Silver Power Sp-SS400 (400w)
