computer suddenly freezes up for no apparent reason Results

Sponsored Links:

So I'm just listening to music & browsing the web, when my PC suddenly slows, the music slows down (i think 1/4 speed) and shoots back to normal and slows down again at random intervals for a few seconds.

I go into Task Manager and end the first process I see (ACDaemon.exe). I figure this is part of my webcam software (ArcSoft IS something I installed for my webcam, and this is "Arcsoft Connect Daemon") and could be causing the problems. However, this causes my PC to completely freeze up and it needs to be restarted.

Here's what I could find in Event Viewer:
1:37:18 The computer has rebooted from a bugcheck. The bugcheck was: 0x00000124 (0x00000000, 0x8b4b28fc, 0x00000000, 0x00000000). A dump was saved in: C:WindowsMinidump42310-32812-01.dmp. Report Id: 042310-32812-01.

I figure the "fatal hardware error" may be at fault, although it happened AFTER I restarted my computer (maybe Event Viewer is a bit slow on reporting errors, because there were no errors after restart. Regarding the BugCheck: I never noticed a Blue Screen error. I just restarted my computer manually. Maybe the 1st two errors are somehow tied together).

I have submitted my minidump file from the bugcheck. All the info from the "hardware error" (#2) has been posted above. Attached Files (10.1 KB, 102 views) Share Share this post on Digg Technorati Twitter

Join Date Apr 2010 Posts 39 happened again this morning. computer apparently froze @ 10:30 (restarted too) and was frozen on the login screen when I returned @ 2:25. No idea why, but it came out of sleep mode and did this.

Hi All,

Since about 10am this morning my PC has suddenly started suffering regular BSODs.

Attached are the things requested in sticky, plus some extra info.

The computer will start normally run normally for an hour or more then crash. The crash happens like this:

First whatever I am doing, gaming, photoshop, desktop will freeze. I try to bing up task manager but get an error saying it cannot open (see jpeg error01).

Then if I have the desktop visible all the icons dissappear, like when windows explorer crashes, then normally the PC will crash and either restart, or BSOD then restart.

The BSOD gives no direct info in capitals at the top, and there is no minidump file produced, even though things are configured like in the sticky.

Additional info:

No software installations or changes for a few days excpet updates (last installation the cry editor 4 days ago)

No hardware changes for a long time.

Antivirus - Microsoft securoty essentials.

Here are some additional images of errors that come up before the BSOD =

This just suddenly started happening today, apparently for no reason, I am worried it could be very serious... more than just a memory that needs replacing. (

PC =

GIGABYTE Motherboard Z68X-UD4-B3
Intel i7 2600K SB (x38 OC)
nVidia Geforce GTX 580 (normal clock)
16 GB RAM @ 1600Mhz
3 Drives (C: and F: drives crucial SSD, D: WD HDD)

Like I said, no changes or installations... the PC has been fine like this for ages. PC can also work fine for over an hour before any problems. RealTemp shows nothing out of the ordinary... PC is a little dusty, Ive been meaning to clean it, but its not THAT bad, I've seen far worse.

Please can someone help? I also just lost my job recently and have no income, so I really cant afford to take this to a store to get it looked at (

Thanks in advace,

Join Date Jul 2012 Posts 9 Re: Please, Please, Please help me! :((( Major BSOD I just found this thread, where the person (as best as I can make out) says that the problem could be caused by the battery.

Could the battery dying really cause a crash after 30 mins or an hour after the PC has been turned on?

However through the whole thread, causes are cited as either, battery, RAM, HDD, or corrupt installation... which doesnt get a whole lot closer to an answer (just add faulty CPU or GPU and that covers everything!!)

There is also this which talks about the minidump file not getting saved correctly.

The problem is I am not sure I really understand what hes saying about it... is it something to do with my C:/ drive being an SSD drive? When my PC was put together a year ago the person who installed windows didnt bother changing IDE to ACHI in the bios, so I had to enable the drivers manually in the regisrty... but i did that well over six months ago and its been running fine.
