When my laptop comes out of standby, the CPU fan is on full and won't stop (the air is cold), this has happened after a reinstall on win7.

As I don't feel like doing another Windows reinstall to stop this, does anyone know what's causing it and how to stop it, also a restart does nothing, I have to shut down and reboot for the fan to "be normal", my previous install (original) was bogged down with too many programs/crap and never did this.

Compaq C700,

CPU->T8300, 2GB Ram, GPU-> Intel GMA X3100 (yea I know it's getting on, but it's ok for my needs)

Any Windows 7 guru's out there that can help.

Fan full of dust?

Lazy is such an ugly word, I prefer to call it selective participation

No, it's pretty clean, it's not running hot, the air coming out is cold.

Same with my laptop. Not a speck of dust but sounds like a boeing preparing for take off.

Hopeless bios on a dying motherboard is my unexpert diagnosis.

Did you install the drivers for your chipset/motherboard?

Thanks

Hmm, just found and installed drivers for "chipset" from the recovery partition for Vista (yep Vista) installed fine on Win7, just have to reboot and let it go into standby and wakeup a couple of times to find out. will let all know later.

No, this has not worked,

I have no idea other than a windows reinstall, until then, the laptop is either on or off, no standby then, but it is ok when it comes out of Hibernate though.
