Hi,

My LCD Screen is flickering once every 2 seconds, it cant be the inverter on my screen as it doesnt flicker on POST Mode all the way upto Logon, its just when my credentials at logon are accepted in windows xp is displayed!

I have tried altering the refresh rate and that doesnt do anything, I have tried scanning my system with an advanced system care utility and still the problem persists. I have also looked for a driver update for my display adapter, and again, no update available!

Do any of you have any resolution suggestions to this annoying problem?

Thanks in advance!

I'm having the same problem, is yours a Samsung by any chance? I think it's the fluorescent back lighting that is finally burning out (in my case). After it warms up (after about 5 minutes) the problem goes away.

Hi Matt,

No my lcd is an Acer, its funny because my LG monitor i had previously has the exact same problem, even more funny that I both bought my current monitor and old monitor from the same store.....Tescos!

My problem is the opposite to yours....when it warms up it flickers! lol

Alex, I would try a different video card if you've had both monitors do the same thing. Could be related to a video card issue when it warms up rather than the monitor. Also check that the cooling fan on the video card is working properly or at all (assuming your video card has a fan). These problems can be reminiscent of overheating. You could also check your system heat such as the CPU in case its fan isn't working properly. I recommend doing a thorough clean out of your motherboard, blowing all dust out of fans and components (of course taking care at the same time). If you aren't confident to do this then take it to a repair store as I don't want to be blamed if you blow it up :) :) :)

Hi Ken,

Your definitely right about cleaning my pc, I am very confident with pc's as I have built a good few pc's in my time, so I thankfully I know what I am doing.

I can actually say that my PC doesn't appear to get a fresh intake of air often as it is wedged in between the left of my wardrobe and right of my pc desk, with a big bulky work top above it.

As for the flicker problem, I have never come across this before hence while being so baffled by the problem.

Anyway, first thing is first, I'll do what you recommend and I'll be back if it doesn't improve lol!

Thanks Ken!

Alex

PS. I will only blame you if it works! lol

I had a graphics card problem around 3 months ago. It went like an old tv with no signal. Black and white slight fizzle and coloured lines down it.

Changed the graphics card and it was fine. So just make sure you investigate before you just to the complusion its the monitor or the CPU or whatever. We don't want you chucking out perfectly good kit.

A good thing to try is connect the monitor up to another computer. Perhaps a friends or at work etc etc. Then that will tell you if its the monitor of the CPU. If its the CPU it'll be most likely a graphics card issue. My replacement cost around 40 fitted. If its the screen then you'll have in fork out a little more for a new one.

Hope that helps, best of luck with the diagnosis.

Well,

Within the last half hour or so I followed Kens advice!

I took the case apart, and to my (not so) surprise the case was......caked!

The CPU fan had a layer of grey spongy dust layered over the fan grill and blades, my display adapter card also had this grey spongy cakey dust blocking just about everything, my poor old card couldn't breathe!

Well the paint brush and hoover was on the attack and sucked the **** out of my pc case.

Put everything back together, and hey presto!!!!!

My PC doesnt have the problem.....and it seems to work faster? Weird!

So many thanks to all you guys for you help!

I am happy boy now!

And cheers to ken again! Im blaming you for it working now! lol

Whew! Thank goodness for that. It probably works faster now because the data isn't being blocked by the caked dust :)

Nice outcome, good advice Ken.

Hey, now I know what my problem is, it isn't the monitor at all, it's all the dust in my head I haven't cleared, no wonder I see the monitor flicker. :) :) :)

New procedure, clear dust from brain first, then turn on monitor. :)
