I'm having an issue with Windows XP Pro. Freezing up. I just put together a custom build for a small office and the PC I built is freezing whenever put under a load. To start off I used: -MSI H61M-P23LGA LGA 1155 Motherboard -2GB OCZ RAM DDR3 10666 (2x1GB) -160GB HDD Seagate 7200 RPM -Power supply 480 watts -Processor Intel i3 2100 (1155) Sandy Bridge -Multicard reader (Generic) -Logitech mouse (optical) USB, HP keyboard PS2 -Microsoft Windows XP Professional (32 bit) (SP3, all Updates, & DirectX 9.0c) -Using on board VGA (this is an office PC, no need for a powerful GPU) -Microsoft security essentials I have had an issue with the computer freezing up after I attempted to install adobe acrobat reader 10. However, I was able to install Windows XP Professional all required drivers, updates, and even service packs including directX without any issues. However, when I attempted to install Adobe acrobat reader 10, the screen developed a fuzzy 2" line from top to bottom using green and black. There were 3 of these lines approximately 3" apart from each other. When this happens the computer locks up solid. Control+Alt+Delete does nothing, the mouse cannot move, and even the keyboard lock keys (Caps, scroll, number locks)are non responsive. I am wanting to know if there is a compatibility issue with Windows XP 32 bit and the Intel i3 2100. I have attempted changing out the RAM and the power supply. The hardware seems to be in good shape but now the computer is locking up if I try to run a program that puts it under a load such as doing a Virus Scan or even if the computer sits at idle for 10 minutes, its locking up. Please I need some help on this.
