Yesterday my laptop of five years surprised me.
The screen had become less focused and I thought it was just because of an outdated graphics driver.
My best description of the issue is random cyan/pinky/yellow coloured pixels appear all over the screen. Like snow. I can still use it, but it's not ideal.
Another important point is that this issue happens right at the boot screen (when it's all black and white writing)
I use this laptop for work so it's really important I get it back to normal as soon as I can.
Never had this issues before.
Alienware R4 17
Geforce M770 graphics card
On going issues/changes to the system -
Random restarts about once ever three hours, unless I'm playing a good quality computer game
Recently replaced the old battery
What I have done so far:
Ran the Intel Diagnostics - nothing
Updated Graphics Drivers - no change
Windows update - nothing
Scaled graphics right down - nope
Plugged into an external monitor - fine on external but still pixelated on the laptop
Plan for tonight:
- Try turning the laptop on and maybe magically it had realised how annoying this issue is and fixed itself.
- Try to re-enable the intel on board graphics card (it is currently disabled and grayed out in the BIOS... not sure how to "Switch it on". Does not come up when I scan for new hardware)
- Disassemble the laptop and check the screen connection and wipe off any excess thermal paste (last part worked for someone else on the internet).
Could anyone suggest anything else I should try?
Or if they had a similar issue?
