Hi techspot, I'm having trouble with BSOD/s occuring only during my first startup. I have consulted technicians for help and so far, these is what they have done. NOTE: BSOD/s already occurs before these changes were made. Intel Core2 Quad Q8300 @ 2.50GHz's 2 pcs of Kingston 2Gb Memory Modules were tested. * Memory Modules have been checked numerous times and they turned out ok. (MEMTEST) * Found a bad sector in previous hard disk and replaced it w/ a new hard disk. * Suggested that the BSOD may be due to the PSU and so I have availed a better PSU. >Video Card, Hard Disk, PSU have been replaced and have been checked. OS Windows 7 64bit format in the new Hard Disk. I thought, these should have solved my BSOD problems. Surely enough, they did not. BSOD still happens during the first startup of my PC. I'm running out of options and so I would like to ask for your help. I have attached the dump files that have occurred lately after these changes were made.
