Hello all! I'm new to the forums here, and I hope I'll meet some nice and helpful people. Well, to start with my problem. For about a month or so I have been experiencing BSOD errors every time I play games, no matter which. It happens at random times, but when computer is idle, I don't get any errors. I was looking around Event Viewer and found this. This is the most recent one: The computer has rebooted from a bugcheck. The bugcheck was: 0x00000077 (0xc0000185, 0xc0000185, 0x00000000, 0x00edb000). A dump was saved in: C:\WINDOWS\Minidump\Mini073111-02.dmp. Every error starts with 0x00000077, but the numbers in brackets are changing. It's like: 0x00000077(0xc0000185, 0xc0000185, 0x00000000, 0x00e74000) x0x00000077(c0000185, 0xc0000185, 0x00000000, 0x00dd9000) 0x0000007a (0xc03deae4, 0xc0000185, 0xf7ab9d8a, 0x22fc2860) 0x00000077 (0xc0000185, 0xc0000185, 0x00000000, 0x00f68000) 0x00000077 (0xc0000185, 0xc0000185, 0x00000000, 0x00f29000). I just copy pasted some of it. And on the top of BSOD window it says: Kernel_Stack_Inpage_Error Here, I'll include the minidump file of the most recent error. I'm using Windows XP SP3 CPU Type Intel Pentium 4 506, 2556 MHz (20 x 128) Motherboard ASRock 775V88+ (5 PCI, 1 AGP, 4 DDR DIMM, Audio, LAN) DIMM1: TakeMS BD512TEC500A 512 MB PC3200 DDR SDRAM (2.5-3-3-8 @ 200 MHz) DIMM2: M2G9JA8AMK9F081CAD 512 MB PC3200 DDR SDRAM (2.5-3-3-8 @ 200 MHz) Graphic Card: ATI Radeon 9550 256Mb Hard drive: WDC WD5000AADS-00M2B (465 GB) Power Supply: ATX, FRONTIER, PSU-400W I checked the HD health with Western Digital Data LifeGuard Diagnostics - WinDlg (DLGDIAG for Windows) and it says: Too many bad sectors detected. I did a S.M.A.R.T. scan too. I will include the picture of it. Could it be my HD since it has bad sectors? Or my Power Supply? Or my RAM because I'm using two different brands? The RAM tiles are placed near each other. Like you know how two DIMMs are split up with 2 on one side and 2 on other part of MBD. the RAMs are in the first two slots. If i take one RAM out and put it In the 3rd or 4th slot, my computer recognizes only 512Mb RAM. If I put the RAM tiles near each other, in 1st and 2nd slot, it works normally. Im not sure if you understand me... But Please can I get some help. Thanks!
