Fixing a Broken Gaming PC That Won't Post

Fixing a Broken Gaming PC That Won't Post or Boot. Today we will take a look at a real scenario where a new computer won't POST or Boot, but fans are spinning. We will need to troubleshoot and diagnose this PC to find out whether what hardware has failed so we can RMA the item. We will use the swap out method with known good hardware to see if we get post to BIOS. This means we need to test PSU, RAM, Motherboard, CPU and GPU.

Can we fix it? Drop us a LIKE 👍

[@TimsComputerRepair]

Well sometimes you roll snake eyes when you assume everything will be fine. It happens to the best of us. Good video.

[@Britec09]

Yeah, normally test.

[@thomasburns1846]

My son built a computer that would not post. Both memory sticks worked, but only one at a time in one slot. I pulled the CPU and found a tiny bit of thermal paste in the underside of the CPU, on two pads. I cleaned the underside of the CPU with alcohol. I used a small paint brush with just a little alcohol and carefully cleaned the pins on the motherboard. Put it all back together and it worked properly.

[@ratix98]

damn, I have this exact same motherboard type. B550 tomahawk and it will no longer post no matter what I do. According to the LEDS on the board where the power cable connects to the board stays solid on VGA and have no video, I also have a speaker connected to the speaker header to give beep codes, 1 long and 2 short. I've tried at least 2 different video cards and the third onboard option and still can't get it to post. i've tried different memory sticks as well. In an act of desperation i even removed the M2 drive then used the EZ flash to reset the bios. i think its safe to say my mobo took a dump on me. The only thing I haven't tried yet is a different power supply. I had the PC for 3 years and it just started not posting the other day! Thanks for reading my comment.

[@hiitsy.gobble]

thank you so much! my pc was not posting after a unexpected crash. all i had to do was try a single stick of ram then it posted!

[@TekNeil]

Opinions? I dug out my first ever PC, a Fujitsu Siemens from circa 1996/97. I powered it up for the first time in what must be 10-15yrs or so and it just woke from the dead like it had never been in storage! Booted with WinXP which I updated it to not long after buying it. Still runs superbly with the IDE drives (Master/Slave), 56K modem and all LOL! No GPU. Question is: What do I do with it? As it stands it's just a sentimental thing really.

[@Britec09]

Not really worth anything in my eyes, but some people like old retro computers and may pay some good money for it.

[@TekNeil]

@@Britec09 Yeah, I'll maybe clone the drives (If I can figure out the master/slave thing) and then clean it up and decide what to do with it. Keep up the good work on the channel.

[@pibbles-a-plenty1105]

My first computer is a first generation Pentium that ran Windows 95. It got updated to Win 98 when an IT guy couldn't figure out that the 56K modem card was bad preventing it from completing boot. He didn't see Brian's video. LOL!

[@TekNeil]

@@pibbles-a-plenty1105 Ha, and that was a big loss back in the ol' dial up days! Good times. But thank God we've moved on...Good to reminisce though.

[@andyk7217]

My initial guess was that it was an unsupported CPU and the BIOS needed updating with an older chip. It just goes to show that although brand new mobo's are rarely faulty, sometimes they can be. Personally I've had the most problems with MSI boards so I never use them any more but as you say, it happens with all manufacturers from time to time.

[@welshtony1]

good troubleshooting video as always :)

Heya Britec! Do these fixes only apply for gaming PCs or can I also use this on my workstation device?

[@Britec09]

Never seen a pc that post. No mail or package, nothing.🤣🤣🤣

I see where your going with that lol

Usefull i really appreciate these kind of troubleshooting videos thank you

[@Britec09]

Glad it helped

[@EastAngliaUK]

did you get it replaced?

[@marcushopkins2290]

Your CPU could have a bad memory channel. I let a repair shop convince me my mobo was defective. I replaced it only to find out my CPU was no good.

[@33lex55]

Had that issue years ago, with a cheap mobo. Turned out the manual was wrong about the primary memory bank.... Sometimes it pays to fiddle around with these things.

I’m not sure if you’ll read this but what if the pc is like this (fans spinning, gpu working, mobo lights are on) but u check the mobo and still doesn’t work? ( pc was fine (7hours+ use on average, daily) and suddenly this happend

[@lukasgustin4631]

Did you fix it I m having the same issue? Need to know if it’s motherboard cpu or psu

[@ejuskoo1837]

Hello, i got a similiar problem with old pc. When i turn on the pc fans will spin fast and black screen. If i want to turn off the pc power button doesnt work and i have to pull off the plug. I have tried changing ram, positions, with or without GPU, taking out CMOS battery, changing disk sata connection and nothing worked. Is there something else i could try?

[@vPA1N]

I have the same problem now. Did you find any fix

[@ejuskoo1837]

​​@@vPA1NYeah look at the pins on the cpu socket many od them were smashed beyond repair. Hope this will help and if i am correct GL.

[@cosmiccouplet]

I am going through this right now with a Z790 Edge Wifi DDR4. 2 dead slots. 4 week RMA, each way. RIP my work flow. Back to old crusty. This PC running at 45% is waaaaaaaay faster that crusty.

[@rebjorn79]

Thanks. Don't feel obliged to reply but I'm currently struggling with a GPU here. I was unlucky enough to yank the hdmi cable one day and it went all black. Unfortunately I've tried many things, reinstalling windows, properly uninstalling drivers in safe mode, reinstalling new ones etc .. just can't get the 1080 to work - HOWEVER, I do get this old Radeon 5770 to work. The system runs just fine with it. Do you think it may have happened that the PCI slots were slightly damaged but only such that the much older card will work - but the 1080 just won't? By this I mean, do you think it may be that the power flow to the motherboard/PCI slots were somehow compromised in such a way that the more power hungry 1080 just won't work but the older, less power hungry one will? Again, don't feel obliged to answer. Just felt like throwing this one out there in case you or someone immediately recognizes an issue.

[@Britec09]

Very hard to say with full diagnosis of the system

[@rebjorn79]

@@Britec09 Thanks for reply. I'll likely end up bringing in another GPU with higher power req than the 5770, perhaps on par with the 1080 or higher - if that one works then there's probably unfortunately an issue with the 1080. At least then I won't have to replace the whole thing just to test the 1080. I've been unable to determine issues with other parts of the setup. Anyway keep up the good work!

[@pibbles-a-plenty1105]

My first rule for building and repairing PC's is build and maintain more than one PC. The additional ones will keep you "on the air" and work as tools to diagnose and repair the bad one.

[@nav2009]

Please note you can remove the bios chip . Flash and it works

[@xtremezone987]

Couldn't you just avoid using that 1 slot since it has 4 of them ? I know some boards like you to use certain order slots for dual channel but wouldn't it at least boot ?

[@mncdssctn9110]

Usually you can, but the motherboard is still faulty, and you will want it replaced while the warranty is still good, because at some point you may want to have four sticks of RAM in there.

[@northwinds9155]

I assumed they test all the parts from the factory before packing it up, still we can receive items with factory defect

[@Boboboy55]

Ye true happened to me

[@SuperFredAZ]

I'm not sure why you didn't just move both ram sticks over one slot. Most users don't use 4 slots.

[@alanarmstrong2323]

Also check for latest bios as well.

[@Britec09]

probably a bad trace.

[@discordmarauder]

I’ve been having similar issues but the tv I’m using as a monitor won’t recognize the pc

[@jaojmnhzhzm]

I just got a Gigabyte B760M DS3H DDR4 and I had this EXACT problem. Going to do a couple more tests just to make sure and then it's on to customer support *sigh*.

[@Del_UK]

Rookie mistake. Building fully in case without a full outside of case test. The cause may be, that there is a short between the memory slot and the case. Yes, I have done this myself by placing a motherboard post in the wrong place. Great video and hopefully people will learn. 🤓

[@Britec09]

When doing as a business, I do power on self test every time. When its for KZbin, not so much...why? it takes a long time filming and getting things right, so I skip power on self test, which I shouldn't, but do as I say and don't do as I do lol.

[@user-qc6yq1jh4j]

i got a computer that post most the time, but sometimes don't and after a few times pressing the reset button it works again.
