Hello Recently my computer started to hangs up (locks up) and I had nothing to do unless to press the reset button. It happens randomly no matter what I do. Before it became to this state of randomly freezing sometimes when I played game I got error from the display driver. I reinstalled drivers it was same. And now I have my PC to locks up randomly with no error or BSOD (And no dump files). My specs are: OS: Windows XP (SP2) CPU: Intel Celeron D 351, 3200 MHz (24 x 133) Motherboard: Biostar PT880 Pro-A7 Combo (4 PCI, 1 AGP, 1 PCI Extreme, 2 DDR DIMM, 2 DDR2 DIMM, Audio, LAN) Ram: 1GB DDR2 Graphic card/GPU: Nvidia GeForce 7300 LE (512 MB) Also I tried to reinstall the OS and it keeps hangs up randomly. Please write what to do. Thank you in advance.
