I am experiencing random BSOD restarts on my Windows 7 PC since I bought it a couple of months ago. These are my specs and the steps I have tried. Configuration: Processor: Intel Core i3 530 Processor 2.93 Ghz Tested with Intel's diagnostic tool, and did not find any problems. DDR3 1333MHz Memory 2X2GB RAM Details: Brand: A-Data I ran the system on a single module at a time, but the restarts continue with each of the modules. Then I ran memtest, it passed. i even used a Corsair 2GB stck instead of these 2 sticks, but no results. ATi Radeon HD5450 Graphics Card Removed the graphics card, uninstalled the ATi drivers, and ran the PC on onboard graphics, using Intel graphics drivers, still the problem persists. Seagate Barracuda 500GB Hard Disk Used another hard disk, but no results. Windows 7 32-bit (Latest Drivers and Updates Installed) Re-installed 3-4 times with different discs, updated, no use. The PC restarts with a BSOD even on a clean, fresh installation, with just the basic drivers installed. Power Supply: Make/Model: Intex Smart IT 2045S+ Wattage: 450W My dealer used another power supply, but the problem continued. Motherboard: Intel DH55TC Thought it was the culprit and got it replaced, but to no avail! Despite all these steps, I am experiencing blue screen restarts at random intervals, such as Internet browsing, playing music, transferring files to phones and USB drives, or when working with office documents. However when I used XP, the BSODs stopped! What might be the problem, and how can I solve it? I am exasperated with this issue.
