Hello, i've bought a pc not long ago and it was running windows 7 (64bit) Running PERFECTLY , never a single freeze or a bsod. Yesterday i went to my brother's office 2 play some games and i didnt take my monitor with me. There was plenty of monitors in the office so i took the first one and plugged it to my pc. Surprisingly windows loaded with a black screen and i could move mouse but nothing was happening. So i restarted same thing black monitor nothing's happening, i plugged another monitor and another but all had same problem. Black screen after loading right where the username and password supposed to come. So i went home took my monitor and hell black screen, i decided to wait and i waited for about 15 minutes and black screen disappeared windows loaded, i thought nightmare was over but after that when i entered "starcraft2" i got a blue screen of death and pc restarted. For last 16 hours i was trying to fix this problem but nothing is helping. Windows is restarting whenever it wants , either if i enter a game such as "fallout 3 ,starcraft2, half life 2, or similar" or even when im just browsing internet. First i get message IE has stopped working windows is looking for a solution. I enter world of warcraft i get critical error game closes few minutes bsod again. I reinstalled windows 7, bsods were still coming, i formatted drive and installed windows XP sp2 updated all drivers and still i get critical error and system restarts. I upgraded winxp to windows 7 and after installing all drivers from ATI and MSI i still get bsods i formatted drive again and install windows XP again. But im giving up, reinstalling windows and drivers just doesnt help. There must be something more advanced which a simple user cant know.. Such as maybe default onboard video card is causing problem or automatic bios update with msi live update 4 did something to the computer. I m guessing its possible to read some info from dump file but i dont understand anything there. Can somebody help me? Here's the current condition of the computer System Information ------------------ Operating System: Windows XP Home Edition (5.1, Build 2600) Service Pack 2 (2600.xpsp_sp2_gdr.100216-1441) Language: English (Regional Setting: English) System Manufacturer: MSI System Model: MS-7636 BIOS: Default System BIOS Processor: Intel(R) Core(TM) i3 CPU 530 @ 2.93GHz (4 CPUs) Memory: 3064MB RAM Page File: 283MB used, 4665MB available Windows Dir: C:\WINDOWS DirectX Version: DirectX 9.0c (4.09.0000.0904) DX Setup Parameters: Not found DxDiag Version: 5.03.2600.2180 32bit Unicode ATI Radeon HD 5600 Series ATI Technologiec Inc.

Im going to install a fresh new copy of windows 7 right now and hopefully it will work but if it doesnt then i will upload a dump file. If anybody had similar problems i would appreciate any advice.
