my sons laptop is running smoothly on games then quite quickly it starts to lag badly. It then might run smoothly for about 20 seconds and then back to lagging.
He has an Asus gaming laptop with 2 hard drives. He was running vista ultimate and all his games and software on one hard drive, and the other HDD wasn't used. After about 8 months of use this problem started with games that had been running really well before.
last weekend we loaded Win 7 on the unused hard drive and it still has the same problem.
So, i think it can't be a registry, or virus, or knackered hard drive problem.
CPU:core 2 extreme qx 9300
Graphics: Nvidia geforce 9700m gt
2 500gb HDD's
1 with Vista Ultimate
1 with Win 7 Ultimate
I just thought I would post it in case anyone else has a similar one.
I had another look around the net googling various things and found a few possibilities. I thought it was going to be a hardware problem.
There was one thing that came up that I thought would not solve it, but I tried it.....the suggestion was to blow compressed air through the fan vent. So I went in and gave a couple of good blasts through the vent and came back to google.
I didn't test it till later on, but it worked fine and is still working fine now. So the problem was dust build up in the heat sink and fan. This must have caused a slight increase in temp above the max running temp and the machine had to slow down to deal with this.
