Chris-W- Posted July 26, 2011 Posted July 26, 2011 My Dell workstation seems to be haivng a bit of trouble lately with video playback. Its a Precision T1500 (specs: here) with an i7 860, 4GB DDR3 Ram, Nvidia Quadro FX580. When attempting to play video, be it embedded flash, DVD, mkv file, whatever; it always blue screens when I either have two or more videos being processed, or occasionally just one open with other general apps (office, chrome, etc). Having used WhoCrashed the dump files show 'Video Scheduler Internal Error' often with watchdog.sys or mctkmd64.sys being listed as the culprit. I've tried updating the Gfx drivers (even tried a different card with no luck) thinking they could be the cause but to no avail Anyone got any ideas? Btw: Re-install Windows would be my last option... Cheers!
jamesfed Posted July 26, 2011 Posted July 26, 2011 Maybe check for a BIOS update or a dodgy stick of RAM?
Chris-W- Posted July 26, 2011 Author Posted July 26, 2011 I've already put the latest BIOS on it, and I've run memtest for an hour with no problems reported
Chris-W- Posted July 26, 2011 Author Posted July 26, 2011 When I get into work in the morning I'll run a full dell diagnosis for a few hours and report back.
jamesfed Posted July 26, 2011 Posted July 26, 2011 One other thing to try is if you have multiple RAM sticks try taking one out and running the system - if it still dies then try the other stick. Although RAM tests are good sometimes the good old process of trial and elim works better
Chris-W- Posted July 27, 2011 Author Posted July 27, 2011 (edited) Ive done a quick test this morning, removing various components to try and determine if its a hardware issue, and have noticed that although the RAM is good, when I remove the graphics card, the system does not boot (even though its got onboard graphics), I just get 6 short beeps . I reckon the graphics/memory controller is nackerd? EDIT: Dell diagnostics has finished, no errors found. Edited July 27, 2011 by Chris-W-
Chris-W- Posted July 28, 2011 Author Posted July 28, 2011 Quick update. I've been on the phone with Dell and, apparently, the Precision T1500 is designed not to work without a dedicated graphics card installed! Surely that can't be right? Why would anyone design a computer that although has onboard graphics, cant actually use it!?
3s-gtech Posted July 28, 2011 Posted July 28, 2011 The i7-860 does not have an integrated graphics core - so although you have outputs on the board, there's nothing to run them. There's no graphics capability on the board anymore - in fact, the Northbridge on Intel boards doesn't have a memory controller either now. 1

The system has got a H57 chipset which does have integrated graphics.
3s-gtech Posted July 28, 2011 Posted July 28, 2011 The integrated graphics on H57 stem from the CPU - that's i3 but not i7. It's not actually in the chipset.
Arthur Posted July 28, 2011 Posted July 28, 2011 All of the second generation (LGA 1155) Core i7 processors have integrated graphics though. 1
