Hello, this is my first post here, and i am quite frustrated by my computer problem lately. In order to cut a long story short, i have the PC since mid 2005, and it ran superbly till now (as in 2-4 weeks ago). The last month, i have been, installing, configuring, reinstalling, trying different drivers, etc. to put it short, I've done everything i could in order to find out exactly where the problems comes from, and at last i am certain it's a hardware related problem, however, during the last few days I've tried to pinpoint the exact failing component at no avail, so here I am, asking for a bit of help in reading my memory dumps. My PC has the following configuration: Operating System: Microsoft Windows XP Professional OS Service Pack 2 0CPU Type: Intel Pentium 4, 3000 MHz (15 x 200) Motherboard: Asus P4P800-E Deluxe System Memory: 1024 MB - 2x OCZ4001024ELDCPE-K 512 MB PC3200 DDR SDRAM (2.0-3-2-5 @ 200 MHz) Video Adapter: Asus V9999/TD GeForce 6800 128 MB DDR2 256 Bit AGP 8x Audio Adapter: Creative SB0350 Audigy 2 ZS Sound Card Disk Drive: Seagate ST340014AS (40 GB, 7200 RPM, SATA) Disk Drive: Maxtor 6B200M0 (200 GB, 7200 RPM, SATA) Optical Drive: TEAC DV-W516GB PSU: Thermaltake Purepower ATX 12V 2.0 - 460W Case: Thermaltake Lanmoto VA1000 BWA As a note, the crashing does occur all the time (however in a few minutes when running 3D applications or games, and at several hours when not). So far i have tested both HDD's (installed windows alternately on both), I also ran the memory sticks one at a time, I also cleaned the CPU and heatsink yesterday (replaced the conductive paste also), which lowered the running temperature back to normal (it was running pretty hot 60C - 70C since the problem started). If they help, i took the components temp right before a crash while running a game and they were: Motherboard 37 °C (around 33 no load) CPU 54 °C (around 41 no load) GPU 57 °C (around 52 no load) GPU Memory 66 °C (around 51 no load) The voltages are all in limits as well (+- 0.1 to 0.2). Frankly i suspect the motherboard or the video card, one of these 2, i will also run more tests on the memory, if any more information is needed i will be glad to give it. I am also attaching the dumps, and mention again that the PC was fine for 1 year and a half (and i really stressed it out, since it's a gaming platform), luckily enough i still have warranty on all the components. Thanks in advance, and hope for some answers pretty soon as i have a lot of exams these weeks and i really need the PC. P.S. The previous errors of which dumps i don't have anymore were usually PAGE FAULT errors and IRQ errors in different modules.
