Gaming PC cut out, doesn't turn on again - LFC#327

My friend's computer died and wouldn't turn back on. Fairly simple problem, here's how I go about sorting it and tidying it up while it's in bits.

The best computer repair channel on the Tube. Others are always building ...not repairing. Thank you Graham.

It's always great when you do a desktop repair!

I absolutely love his DESKTOP PC troubleshooting videos.

Haven't watched one of your videos in a bit. My loss because now I remember how good you are at your job.

Hi Graham, regarding cleaning like you ive always gone the extra mile, sometimes appreciated sometimes not! however depends how far and what the issue is when you have repaired hundreds of PC`s becomes second nature and assists with visual checks on componants. peace of mind that you present the customer with a healthy build, and clean! 80% of my customers did notice and appreciate! keep up the good work buddy, I had two shops and a mobile video/DVD rental ....retired now but 35 years in the business, I have learnt a few thing watching your channel and love predicting the outcome!!!! well done.

It's been a while since you had a gaming desktop on your LFC series, great clip as usual.

8:53 - Off topic, but the way the two camera feeds are set up for this section just makes it look like Graham's got a tiny head on a normal-sized body, and I had a chuckle.

Nice little computer that came with that dust collection 😂

Great to see a PC repair video after a long time. Love your content and keep up the great work.

Awesome way to hook up a friend. I agree when I disconnect any cables that I might as well do a clean down of the PC with air and a cloth.

Found Graham when my pc developed a fault and was looking how to repair it. Found myself having watched every one of his videos 2 weeks later due to the sheer enjoyment I got from watching them. Great channel, great information, great presentation. Keep it up Graham! Also his live streams on the second Chanel adamant it 2' are fun to watch and partake in. Even though carradog can blow my eardrums out once the ciders kick in. 😂

What a great job you have done with that PC! I hope your mate appreciates it - well done. It's so good watching your methodical approach giving clear explanations of what you are doing throughout. Thanks

Graham, The 👏video quality is really amazing. In addition to your excellent repair information, the quality/clarity of the video is superb! You really have mastered your video camera techniques👍

Power supply repair may well be complex however I would always check the fuse for a quick k win be it external access or inside cage.

[pekitivey]

Really enjoy these type of videos. Especially when discussing the economics of running a repair shop.

[hansensor]

I find your videos relaxing. And if I do nod off I always watch it twice...

[uglybob]

I just love all of the DIY and dust on that PC interior. Too busy gamin' to give it a good clean ;-)

[randy]

FTR. I thought I was subscribed but I wasn't. I am now. I love that you go to so much effort in your videos even down to flashing rom chips and sometimes replacing them.

Great video but I am unsure why people get so hung up on dry thermal paste. A decent paste will transfer heat when dry.

The single most important job of thermal compound is to fill in the microscopic imperfections in the metal in both the heatsink and CPU heatspreader. So that there is proper contact. Thermal paste can and does do this dry. It needs to be moist so that it can be applied, but once in place, a decent dried up paste does the job just as well as a newly applied moist one.

Thought the best advice from the start is to tell the customer or friend that good all round maintenance, like keeping dust levels down and general air blasting their system from time to time would be half the battle. I enjoyed the great content though :)
