Problem,

OS system freezes up. Can not move mouse,ctrl/alt/delete does not work,sound goes dead. Only solution is to pull mains power out and reboot.

Happens no matter what program is being used, maybe after minutes or hours,but happens in daily light usage.

What I have tried so far without any success.

Memtest ran for 24 hours and no errors.

Had Motherboard exchanged.

Brand new Seasonic x 80 gold plus psu

Tried running OS on another hard drive

Installed latest drivers including,

Catalyst 10.2

I had this built as an HTPC for mainly media usage, play hd movies and music and occasionaly browse the web.

I had a problem with the case touch screen going dead and I changed the origanal motherboard and did a few minor upgrades, this solved the screen issue, but now it freezes up?

Any one know what else I can do? It has been driving me nuts for months.

I have been having this problem since I upgraded my mother board, graphic card, ram and power supply.Every thing else forinstance the amd 9500 cpu was fine on the old mb.

I have managed to open the event view, but can't work out how to publish the screen shots.

However I found 9 critical errors, and I have pasted them here:

Can anyone tell me what the problem could be from this? I am thinking it sais power becuase I have to turn mains power offf to get it working again?

I've been running my Lenovo T61p for 2 years using XP w/o lockups.

I did a full install (not an upgrade) on a new harddrive a week ago.

Win7 Pro 32.

It ran fine up until yesterday.

I had installed some gadgets & a couple of programs (Adobe Acrobat & MPLAB).

Last night my machine locked up & needed a hard reset.

This morning it locked up/froze twice more.

IE is sluggish...

My hardware is fine.  This isn't a memory issue... I ran the tests w/o fail.

WinUpdate failed this morning for the first time ever... it was a Broadcom Bluetooth update.

I hope some figures this out soon.

I'm having the same problem as JakeyDood.

System specs:

CPU - Intel i5 Core 750

Mobo -

GPU - GeForce 9600 GT

4 GB DDR3 Ram

1 x Samsung 500 gb hdd

1 x Western Digital 80gb hdd

Windows 7 x64 Pro, installed on 80gb drive, one partition, C drive.

Ran fine when I installed it with my new hardware (mobo, cpu, gpu) after an upgrade on Monday. Last night (Wednesday) I got hold of the Left 4 Dead 2 Demo on Steam, downloaded no problems, played it for a good hour or two. Turned on my pc this morning, have a list of things to do - install antivirus, install games, updates, patches etc. Opened Windows Media Player to get some music going while I did all this, OS started staggering, music was staggering, playing for several seconds and then stopping, repeating this process.

After a minute, it locked up completely. It took several minutes to respond at all, but keyboard and mouse input was unaffected (cursor on-screen moved, capslock, numlock lights were responsive). After a few more minutes I got blackscreened. Again, mouse and keyboard were fine. After half an hour my desktop background came up, keyboard and mouse still going. After another hour of waiting, nothing else happened. I rebooted, checked logs - no problems.

I installed AVG, Spybot S&D and Malware Bytes, tried running scans one after another - OS froze as described previously after only a few minutes of logging in.

I have left the login idle after restarting previously, it too froze after a few minutes.

Tests I have performed since:

Ran safe mode - runs fine, no freezes so far.

Anti-virus, anti-malware, anti-spyware scans - reporting no problems

Updated drivers (mobo, gpu)

Updated windows 7

Removed previously installed software (Call of Duty 4, Steam platform)

Attempted reinstalling, OS freezes

Checked running temperatures - everything is running within normal temperatures (no more than 30 degrees celcius)

Used system restore to a restore point created Tuesday 3rd November 09 - still getting freeze issues.

I have tried rolling back drivers and even a format and reinstall - still getting this freeze problem.

Occasionally I hear one of my drives making a 'click' noise, but it has done this a lot recently, not entirely sure why it does that. Old drive I guess.

Update: While I've eben typing this out, my comp has frozen up in safe mode at login screen. Not very happy about this at all.

OS runs very well, loving it up til now. hope there's a fix for this later.

Thats exactly what I get.....
