Hello, I've been having troubles with my laptop lately and I wonder if you could give me hand.
I'm having poor performance when I'm playing games. I get like massive lag spikes, which makes gameplay impossible. Then, when I run the task manager, I can see that many processes have a lot of cpu usage, and many processes are very random, so this is very annoying and I think it's hardware-related. I also reinstalled windows last night and problem is still there (it's not a virus problem because my windows came with norton 360 for free, and I think is a good antivirus)
Anyway, my specs:

Cpu: Intel Pentium Dual CPU T2390 1.86 ghz
RAM: 2 GB
OS: Windows Vista Home Basic 32 bits
Video: Intel GMA 965 express family
120 GB HDD
BRAND NEW OS, NO MALWARE

Oow, yes, almost forgot, my computer heats up a lot, when not doing anything, average temp is around 60º C, when playing, average temp is around 90ºC (It once reached 100ºC)
I hope you can help me.
Thanks anyway.
