Windows 7: High DPC with fan spin up and ACPI issues

High DPC with fan spin up and ACPI issues

Hello everyone! I hope someone can help me.

I recently reformatted my laptop (Toshiba P100- PSPA6C-SD802E - Satellite P100 product contents) and I am having a lot of trouble playing computer games or even watching youtube. Every few minutes or so the entire system would lock up for a few seconds and the CPU fan suddenly spins up and then is free again. This makes watching videos and playing games impossible!

I used xperf to try and figure out what's wrong and I found out that my ACPI.sys is what's locking up the system. I used a DPC Spike Checker Tool (TC Electronic) and it's spiking around 8300 microseconds...I'm not sure if that's helpful.

What I'm finding really curious is that at the exact moment my computer freezes, the fan spins up to 100% and then back down to normal. It is VERY irritating.

I've tried reinstalling all my drivers, updating BIOS, even trying modded graphics drivers to see if it would fix the problem but nothing has worked so far.

Any ideas?

Thanks in advance!
