cooling fan problem on laptop, can anyone advise??

[rob70]

Hi guys, am new to the site and must tell u am not a PC specialist or expert in anyway.
i go a laptop acer intel core 2 150 ghz, 2gb ram.160 hard drive.it was at origin pre loaded on vista. A friend of mine replaced the vsta with xp professional and later carried out a partition, loading up both vista an xp so I have the choice when I boot my pc.
the problem is that since I got both systems loaded up , when my pc is turned on and set on vista or xp It often times turn off by itself. THE reason being because the cooling fan does not work properly and I notice that sometimes it stay silent and stationary that renders my pc overheated and ultimately turn it off by itself all of a sudden.I think the 160gb hard drive was split roughly as follows; 87gb n vista and 61gb on xp.
Please note that for as long as my pc was loaded with ONE SYStem ONLY (i.e xp)I never experienced this hassle, it only started giving this problem once my pc got pre loaded with the 2 systems. can anone explain why and how I can fix this?? thanks in advance

It's because the motherboard needs drivers to control the hardware.

When you reload the OS's you need to install the motherboard drivers for each OS.

There is hope for your Vista partition, as your laptop came with Vista installed, so the computer manufacturer will have all the Vista drivers you'll need.

The problem with putting XP on that machine, is that the manufacturer may not have offered your hardware with XP on it, so there may not be drivers.

You'll need the exact model number to find the correct drivers.

hanks a lot for ur advice, sorry my lack ofxpertise but what OS stand for ??
my model, by the way is ASPIRE 5720.
also can u explain why at some point the same pc was loaded on XP only and there was no sign at all of experiencing this problem, I mean why It only began this cooling fan hassle from the very time I preloaded it with 2 systems at the same time???
what would u suggest to fix this problem ??

OS meaning Operating System. (Windows XP, Windows Vista, etc)

I believe you need to install the Chipset drivers in order for your motherboard to be able to control your fans(s).

All Vista drivers for your machine are located here:

As for XP, they didn't offer that computer with XP so there are no drivers listed for Windows XP.
