Question about Toshiba Qosmio X505Q896 Q4 PQX33U052025 PC Notebook

3 Answers

I have what appears to be an extreme video card overheating problem on my Qosmio 505 quad core i7. after some use (usually 2-3 hours) the screen will, A) freeze with slight static coming from speakers, B) screen will freeze with regular system and game sounds still playing in the speakers, C) screen black out with no sound coming from speakers, or D) screen turns red and there are no sounds. In all cases the computer is rediculously hot above the keyboard in front of the screen. I have a laptop cooling pad and that did not seem to help. As silly as it sounds, even though the pad is beveled with the intake on the back, i turned it around so that the intake was on the front because the Qosmio's fans exhaust the heat out the back and with the cooling pad intake back there it was just circulating hot air. This seems to be working at the moment but I was hoping for a less make-shift solution. Would upgrading my grafics card lower the heat if it was not working as hard or is there a really good cooling pad available? Your assistance in this matter is greatly appreciated. Thank you.

I would tend to believe that the issue is not necessarily an overheating graphics card as much as an overheating processor. If you live in an enviornment with alot of dust or pet hair, this can get caught in the heat sink that sits on top of the processor, and this doesn't let the fan adequetly cool the processor. I've done these types of fixes before. I would recommend buying a can of compressed air and blowing it through the exhaust ports on the laptop. blow it from both sides (intake and exhaust) and see if anything comes out. If it is pet hair, then i would recommend taking the laptop apart and seeing if there is debris in the heat sink. You would be surprised what builds up inside the laptop over time. I hope this helps you.

I've had this same problem. A couple of things I did:
Switched to a solid state drive - the fan seldom even comes on now.
This is obvious, but have you blown out the vents with canned air? Is the GPU fan spinning?
Check the Toshiba site: there may be a BIOS update. You can also look in your BIOS to check the temps.
I also, highly recommend going to the LaptopVideo2Go site and looking for the newest WHQL drivers for your card - a lot of times this is misconfigured drivers.
Good luck - I know how frustrating this problem is!

Sounds like it would be a good idea to have your laptop serviced by a computer engineer, there are things that can be done to reduce the heat over the GPU...for instance...in most laptops the heatsink is shared by the CPU and the GPU with (in most cases) a small heat pad on the GPU to draw the heat away, this small pad can be replaced with a copper shim and heatsink compound which makes a big difference, also while the engineer is in there he/she can remove any fluff and dust from the fan which might not be helping the matter. A senceable engineer should be able to do this for around £30-40.

Hope this helps

INTEL CORE 2 QUAD Q9300 GRAPHIC MEDIA


The Core 2 Quad Q9300 does not provide any graphics hardware, only newer CPUs, e.g. Core i3/i5/i7 (and not even all of these) do.

You need to buy a dedicated graphics card and put it into your computer. Installation instructions and driver software usually come together with the card and are specific to the exact brand and model you choose, plus is dependent on your operating system.

Without more information on the exact hardware and software configuration of your computer I cannot give you more help.

Which is the best cpu that can i buy? i have the gigabyte 8ipe775-g rev 1.1 thanks


Well that is kind of a far off question. Do you want to know the best processor on the market or the best processor for your motherboard?
The best one I would say for your motherboard (LGA775) would be Intel Core 2 Quad or Intel Core 2 Extreme (The extreme is just an unlocked and overclocked Core 2 Quad)
The best Processor on the market however would be on the LGA 1366 and LGA 1155 Sockets as teh Intel Core I7.

The processor is too weak - get at least an i5, best would be a quad core i7; the hard drive will be filled faster than you thing - bigger is always better; get some faster memories - at least 1666 MHz, 4 GB is bare minimum, get a 64bit OS and 8 GB for real performance; the power source is at the limit - for best result get one of 600W; as for the video card the best for photoshop is Nvidia Quadro CX, even ATI Fire will be better than any gaming card.

The onboard ethernet card just stopped working. There is no fix I can find. I reinstalled windows and the drivers. once you instal the driver it only will start in safe mode.


Reboot your PC and hit F10 or F2 or any key it shows on your screen and go into BIOS setup and there should have one entry you can disable the onboard ethernet card.

File setudd.sys coud not be loaded the error code is 4


This error code has to do with a hardware fault which is probably the RAM. Remove the RAM sticks and replace one at a time. After the OS is installed try installing the remaining RAM sticks. If the RAM removal doesn't solve the problem then try changing/reseating the video card if you are not using the onboard video connector. Steve Medley
