There may be a question like this, but my situation is different.
I am on an:
HP Pavilion dv3
Windows 7 32 bit
3 GB RAM
286GB Hard Drive
Intel Core 2 Duo P8700 2.53 ghz
Nvidia Geforce G 105M
The computer is unmodded and stock.
The computer seems to crash after a few minutes of playing games like Minecraft or World of Tanks. When it blacks out and crashes it makes a 0.1 second long whining sound high pitched.
Also, during normal usage (no games) (im doing web browsing) the fan runs hot and pretty high pitched too.
