Hey Everyone this is my first computer and has been nothing but problems, My PC specs are, Intel Core 2 Duo E4400 Samsung 400GB 7200rpm ABIT Fatal1ty FP-IN9 BIOS v14 Corsair HX-620HX 620W EPS Modular Power Supply Crucial 4-4-4 EPP PC2-6400 Ballistix 2gb Kit ECS 8600GTS 256MB Now Inno3d 8800 gts 320mb Info I tried to clock the CPU fsb once but theres a problem with the FP-IN9 bios v14 with the E4400, and even if you change the FSB by 1 it won't post. I don't think it damages anything since it doesn't post when it does this (I hope not anyway haha). At the moment everything is at its stock speed. PC is about 2 months old, but has done hardly done any work. Stock intel cpu cooler so it is blowing air down to the northbridge. Windows XP Professional Service pack 2. Video, Bios drivers, and latest Direct x 9c. I sent back the 500g hdd that came with the computer because it was very noisy, i bought a 400g samsung and its a little loud but not that bad. When the computer arrived the motherboard wasn't screwed in, I dealt with the company and I fixed up the computer. I got extended warranty on the MB and got my 8600gts replaced with an 8800gts. The Errors, 0x8e 0x0a 0xd1 0x50 The errors have been from 162.18 nvidia drivers, ntkrpamp.exe, win32k.sys, memory corruption, hardware(realtek onboard audio), explorer.exe, system.exe. I don't have access to my mini dumps at the moment. What i have tried, I have tried using a different ram stick. I have the abit MB program running always monitering volts and temps i never get an alert that there overheating. I have reformated the hdd and installed Windows XP SP2 with an offical disk and installed minimal drivers. Ran memtest, 25 passes no errors. Read through the BSOD crashes to try and pinpoint the problem but it seems so random. I ran a Hotcpu test for 6 hours and it had no errors for my CPU. The Programs, My first crashes were with World of Warcraft, first the game crashed and the sound stopped. I restarted the computer and the sound worked I played the game again and I got a BSOD, and when the computer restarted and windows tried to boot i got another BSOD. Warcraft 3 crashes often with "memory could not be 'read'" but never had a BSOD when playing. The story. I had errors from the start and there was a problem with the computer when it turned up so I got a free upgrade from an 8600 to an 8800 since I thought it was that causing the errors. I changed the 8600 to an 8800 then my motherboard wouldn't boot and the error was that Dram wasn't inserted properly. When I correctly inserted the ram it would start to boot windows but then instantly BSOD. When i took 1 ram stick out it would boot fine. Because the computer crashed so bad with the 2 sticks of ram i sent the ram back to the company to get replacements. So I borrowed a 1g stick of ram (that worked perfectly before now) and put it in my computer (Note: The new ram was 667mhz and i didn't reset my bios before putting it in, i did however check the bios before it booted and checked that the setting was at 667mhz which it already was). It didn't take long and it started BSOD'ing again. I have ran memtest on this ram and i got 25 pass no errors, so i reinstalled Windows Xp pro SP2 with an official disk and only installed the drivers I needed for the computer to run and again I got another BSOD. So I'm thinking that my MB's faulty rather than my ram. But, Could a faulty HDD cause these problems?
