Sorry if in wrong place. hi all, got a prob thats bugging the hell out of me, built a new pc around xmas last, with following specs Operating System MS Windows 7 Ultimate 64-bit SP1 (Downloaded from link from here) installed on date below, had 32 bit since xmas. CPU AMD Phenom II X4 Deneb 45nm Technology RAM 4.00 GB Dual-Channel DDR3 @ 439MHz (6-6-6-15) Motherboard ASRock N68C-GS UCC (CPUSocket)44 °C Graphics Generic Non-PnP Monitor (1280x1024@70Hz) ATI Radeon HD 4600 Series (XFX Pine Group)46 °C Hard Drives 313GB FUJITSU MAXTOR S TM3320820AS SCSI Disk Device (ATA) 313GB Seagate ST332062 0AS SCSI Disk Device (ATA) Optical Drives TSSTcorp CDDVDW SH-S223L SCSI CdRom Device TSSTcorp CDDVDW SH-S223L SCSI CdRom Device Audio ATI Function Driver for High Definition Audio - ATI AA01 MS Windows 7 Ultimate 64-bit SP1 Installation Date: 29 June 2011, 20:25 Serial Number: *****-*****-*****-*****-***** As you can see i am running 64bit OS and its not been installed a month yet, but every day i am getting BSOD's all the bloody time at different times of the day, i have done all the latest drivers for all the stuff i have and all are up to date, CPU is unlocked and oc'd to 4.20g even if it's stock i am still getting BSOD's for different things one time it might be fltmgr or ndis or win32k so as u can see it's not the same thing every time. So would it be the copy of win7 or is it something else?? Have searched the web for answers but their doesn't seem to be a fix for this. Oh this never happened when i had 32bit version installed at all and nothing has changed in the machine. so can anyone shed any light or has any one else had/have this problem too. TIA.
