Hi all who read This is my first post so please bare with me. I have recently found myself using the site alot for reference however have hit a bottleneck and don't know where to turn next, please help if you have any advice - it is much appreciated System Spec Thermaltake Soprano ATX Case – VB1000BWS 520W Coolermaster Real Power M520 Modular PSU GigaByte GA-8TRS350MT Motherboard Intel(R) Pentium(R) 4 CPU 3.00GHz 2Gb (2X1Gb) Corsair Value Select DDR PC3200 (400) nVidia GeForce 7600GS APG8X 256MB DDR2 128bit (M) 80Gb Western Digital Caviar SE, SATA300, 7200rpm, 8MB Cache, 9 ms ( S ) 80Gb Seagate Barracuda 7200.7 80, Ultra ATA/100 HP DVD1040i Lightscribe DVD±RW Writer Windows XP Professional SP2 System History I have recently upgraded alot of parts on my system..previously I was running the Gigabyte motherboard and cpu with two IDE drives, 512MB Ram and a 300W PSU. I then bought the nvidia gfx card as new from a friend and had this running on the old system for about a month with no problems. I then upgraded the case, PSU, RAM, SATA drive and DVD drive just after christmas. Since then I seem to have problem after problem. The Problem/Problems Since the upgrade, I have had various BSOD while doing different tasks and programs randomly closing on me with the usual windows error message. There seems to be no link between the BSOD as they can range from windows drivers to gfx, sound or mcafee software. More recently the BSOD has not been appearing as often, however program crashes are becoming more frequent. I started to log the errors and what I was doing at the time, I will attach this with a few minidumps to check over. What I have tried As mentioned I have used the site quite a bit recently, so have done the usual things you see posted on various similar threads. I have formatted more than once (with a copy of windows I have not used before) and installed all the upto date drivers available (Chipset, lan, sound, sata drivers from gigabyte - video driver from nvidia). All setup processes run through fine with no problems. I ran Win Memory Diagnostic and Memtest86 on seperate occasions with no fails...details can be found in the log. I ran 3DMark6 numerous times with no crashes and a score just short of the best for similar systems. I ran various anti-virus software - Trend Micro, Mcafee, Kapersky with no real threats detected. Altho with the formats I have done i doubt this is virus related. I have checked cpu temperature at various times and it always seems to be around 40 degrees..the case is well ventalated and i doubt this is caused by overheating. Plea for Help Like many people who experience the same thing, this is becoming a real annoyance - not only from the BSOD but the fact I splashed out to upgrade, however my system is now worse than before. Please Please help if you can - Thank you to anyone in advance!
