I don't know how this may help but my friend has a laptop which lags for certain games. Unbelievably it lagged for CS 1.6 which demands very less resources. His laptop was an 3rd Gen i5 with 4GB RAM and some decent AMD 1GB graphic card. He found out that the reason of the lag was that the game was using the integrated graphics and not the AMD card. Wierd. He used to get 80+ fps but it dropped to 25 during max load. Could it be that only certain games are lagging? You said the whole system lags...that happens immediately upon booting?
Is your senario like this? You start the PC - it works fine - run a CPU intensive (or resource intensive) application - the application laggs - you shut down said app. - but the system still lags.
P.S. My freinds laptop started lagging (later on) when playing DotA 2. Was getting under 20 fps. He opened it up and cleaned all the dust. Now it works fine 😀
got a can of compressed air blew all the dust out and no fix
🙁 seems as though i have tried everything.
Well you've checked the temperatures, ran a mem-test, changed the battery, cleaned out all dust. Seems like the suggestions aren't the source of your problem. Looks like your hardware is failing, now your best option is to give it to the service center....
