I recently got myself some parts for a new computer, while using a few bits from my old one. My problem is, on startup, mostly if it hasn't been turned on for a while, my computer blue screens a couple of seconds after it says "Windows is starting". It will then restart and offer to try and fix the problem. This doesn't work, so I skip this and it loads up fine. I don't remember it ever crashing in the middle of me doing anything, which leads me to think its not a RAM or overheating problem. Also, it does not always BSOD, only sometimes. Maybe like 1 in 5 after not using my computer for a while. I am using Windows 7 64 bit. I have overclocked my processor to 3.4 GHz. I have: Gigabyte EX58-UD3R Motherboard i7 920 Processor 6GB (3 x 2 Sticks) Corsair XMS3, DDR3 RAM ATi XFX HD 5870 XXX Graphics card 900W Quiet Quad Rail PSU + 120mm Case Fan My error reports are: Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7600.2.0.0.256.1 Locale ID: 2057 Additional information about the problem: BCCode: 50 BCP1: FFFFF80100004817 BCP2: 0000000000000001 BCP3: FFFFF80002ADE19C BCP4: 0000000000000005 OS Version: 6_1_7600 Service Pack: 0_0 Product: 256_1 I have included my .dmp file as a zip because the file is too big to fit within the forum attachment limits. Hope I have zipped it alright. If you need anymore information or for me to run something or take my computer to bits, please let me know. Any help would be really appreciated with this problem.
