Freezes, crashing and random restarts (very few BSODs)
Hi,
I'm getting frequent crashes on my HTPC in Windows 7 usually without a blue screen of death (I have had maybe one or two BSODs). Sometimes the computer will crash almost as soon as I switch it on (i.e. when I'm using internet explorer), sometimes it crashes when watching a bluray in media center and sometimes when doing nothing at all. The system was stable, however about 5 months ago I installed a new CPU and cooler, and about a month or so later I started getting these problems. I have tried the following: - Virus scan - Memory check (memtest86 multiple passes) - CPU stress test (prime95) - Hard drive check disk - Graphics card stress (furmark) The graphics card did show signs of overheating and the PC crashed shortly afterwards, however I have since tried the onboard graphics card and the problems are still there. The fact that the PC can crash shortly after booting also suggests its not this. I can only think of three things that it can now be: - Power supply (no idea how to test this, the power supply is a good quality Corsair, with more than enough power for the components and like I said, the system used to be stable). - Motherboard (could be this I guess - potentially I damaged it when I installed the new CPU) - Windows 7 (hence the reason I'm here!) In trying to fix the PC I have used a registry fixer by a reputable company (I forget which one). I can find two mini dumps on the PC (both from yesterday when I was doing some testing) with the following strings: 010211-12573-01.dmp 05/06/2011 16:33:25 DRIVER_IRQL_NOT_LESS_OR_EQUAL 0x000000d1 00000000`00000070 00000000`00000002 00000000`00000000 fffff880`0418e2c0 usbehci.sys usbehci.sys+72c0 x64 ntoskrnl.exe+70740 051511-56066-01.dmp 05/06/2011 16:20:39 KMODE_EXCEPTION_NOT_HANDLED 0x0000001e ffffffff`c000001d fffff880`00000000 00000000`00000000 fffffa80`04474800 aswSP.SYS aswSP.SYS+15501 x64 ntoskrnl.exe+7fd00 I've tried searching for information about these, but there is nothing particular clear or relevant to my situation, so I'm all out of ideas - any help would be gratefully received!

So for first step remove avast and for now download and install MSE http://www.microsoft.com/security/pc-security/mse.aspx ----------------------- Wait and... Please post back with any results! |

Thanks for your help, I've uninstalled avast and installed the M$ version - for a brief moment I thought you fixed it - the PC worked for a while so I took the opportunity to run some virus scans (all came up clean), but during one of the scans I had a crash.
No BSOD - just a white screen with lots of artifacts on it - required a reboot to fix. I'm thinking this is a hardware problem but would love to be corrected. |

Hi Panais,
Sorry for the delay in reply - I couldn't try this until I got home from work this evening. I reinstalled the graphics driver, and to my disbelief it seems to have worked! I haven't managed to crash it since, and I've been trying! Hopefully this is the end of my problems and I'm not speaking too soon! Thanks ever so much for your help - its really appreciated. I owe you a virtual pint ![]() |

Unfortunately I spoke to soon - crashing is back. I don't think it can be the video card, as I have the same problem with both my HD 4550 in the PCI-E slot, and with the HD 4300 on board graphics.
I think it must be hardware - I'm assuming its the motherboard as I can't see it being the power supply, although happy to be corrected...! I have some other odd things occuring - one thing is when ever I log in using logmein, the computer often crashes, and when I click whilst logged in this way,things happen twice (like a click on a program, and it will load up to of the same program etc). The whole things seems really odd - I'm tempted to do a reinstall to see if this improves the situation. |
