New gaming PC problems

boomstick76 · 10 Dec 2025 at 20:38

I ordered a new gaming PC from Overclockers on 8-11-2025 using the configurator on the Overclockers website. The spec I ordered included:

AMD Ryzen 7 9700X Eight Core 5.50GHz (Socket AM5) Processor - Retail
Asus TUF GAMING B850-PLUS WIFI (Socket AM5) DDR5 ATX Motherboard
Asus GeForce RTX 5070 Dual OC 12GB GDDR7 PCI-Express Graphics Card
Build Stock Microsoft Windows 11 Home Advanced - Systems

The PC was delivered on the 26-11-2025. I unboxed, plugged everything in and connected my monitor via HDMI cable to the HDMI port on the GeForce RTX 5070 (my monitor doesn't have a display port).

First problem:
I powered on the PC for the first time, and the monitor shows me a message saying there is no signal. I disconnected the HDMI from the HDMI port on the graphics card and plugged it into the HDMI port on the motherboard, whereupon the monitor kicked in and I got a screen. I then went through the Windows 11 setup process and got to Windows desktop. From desktop I went into Device Manager and then the Display adaptors setting only to find no entry for the GeForce RTX 5070. The only entry present was for the internal motherboard graphics card (AMD Radeon(TM) Graphics.). I select View > Show hidden devices, and an entry for the GeForce RTX 5070 appears, but is "greyed out". I right-clicked on the GeForce RTX 5070 entry and select Properties and the status says

"Currently, this hardware device is not connected to the computer. (Code 45)
To fix this problem, reconnect this hardware device to the computer."

So my first thought was maybe the graphics card drivers aren't installed and so I downloaded the latest drivers from the Nvidia website, but couldn't install them because Windows doesn't know there's a graphics card there! I then restarted the PC and got into BIOS to check the main GPU was set to PCIE, which it was. I also update the BIOS to the latest version using the official download from the Asus website. After restarting the PC I get back into Windows but still no graphics card. After a short while the PC locks up and becomes unresponsive. I manage to restart the PC, but it boots into Windows safe mode and attempts a recovery!

Second problem:
I manage to get the PC to start up again and go into Settings > System > Storage > Advanced storage settings > Disks & volumes and can see that SYSTEM FAT32 EFI system partition says "Full repair needed"! I used CHKDSK to check the NVME drive upon restart but during this process the PC hung and I had to do a hard reset. Eventually the PC started up and I got into Windows. The partition still has the "Full repair needed" message, but this time the GeForce RTX 5070 appeared in Device Manager! At this point I installed the full Nvidia drivers for the graphics card and all seemed to go correctly.

Third problem:
I restart the PC and it gets back into Windows. The EFI partition still says "Full repair needed", and the GeForce RTX 5070 adaptor is shown in Device Manager. I then decide to connect my XBox controller via Bluetooth to the PC, which completely fails. I try with my phone and work phone, and nothing connects. I turn the Bluetooth off from Windows taskbar, and the Bluetooth button vanishes. After a restart I look at the Bluetooth properties in Device Manager and there is an entry for a generic adaptor, which appears to be working. I go to Settings > Bluetooth & devices and it says "Bluetooth is turned off" even though the slider is in the On position. I try to add the XBox controller again and nothing happens. I turn the Bluetooth slider to the Off position, and then back to the On position and the Bluetooth settings vanish completely. I try to update the Bluetooth drivers to the official Asus ones from their website, but I still can't make connections to any other Bluetooth device.

I also check the Display Adaptor settings and see that the GeForce RTX 5070 is no longer listed!

So, at this point I have a brand new gaming PC configured by Overclockers that:

Does not work out of the box, right from day one!
Often boots without recognising the GeForce RTX 5070 graphics card, reporting Code 45.
Has a corrupted EFI boot partition.
Has no working Bluetooth irrespective of using the Windows generic drivers or those produced by Asus, and in Device Manager often reports Code 43 in the Properties.
PC often hangs and restarts in safe mode.

I raised a support ticket with Overclockers support on 5-12-2025 and have had no response yet. Their phone lines are down and I can't communicate with anyone there. I've seen all the notices about Black Friday and "We're experiencing a high volume of tickets..." but Black Friday was 12 days ago!

Can anyone suggest anything else I can try with my PC to fix some of the issues while I wait for Overclockers support to do something?

Many thanks.

Correct power leads connected to the graphics card ok?

You could check if the power cables for the GPU haven’t become lose, at either the gpu or psu ends, you could also try reseating the gpu as sometimes stuff could come loose in transit.

Have you checked to see if you need to configure any settings in the bios for Bluetooth since you did update the bios?.

Do you have the WiFi antenna connected as you’ll need that for Bluetooth.

This is the second thread involving a new pre build that doesn't work.

I thought the idea with pre build was to avoid these issues as you are supposed to be buying a PC built by a qualified technician and fully tested, ready to plug and play out the box?

If I was to hazard a guess at this stage it would be some kind of logic corruption. Is the system overclocked? Possible over tightening of cpu cooler, memory settings etc.

Either way I wouldn’t touch it till overclockers gets involved.

This, but I'd pull out & re-seat the GPU and the Ram in their respective motherboard slots. Honestly a partly connected GPU or Ram could easily cause all your other issues.
Moving the ram to the other pair of ram slots might also diagnose an improperly seated CPU, which I definitely wouldn't touch without OC involved.

To be fair we also don't know how these deliveries are treated during Christmas.

I take deliveries often here and the back of the vans and trucks often look like they rolled with boxes all over the place.

My last delivery was 10 fans, left next to a bin and I was lucky it wasn't raining, delivered days early, and no attempt to deliver to the neighbour who was in and which was on the delivery instructions if I wasn't.

Thanks for the replies and ideas so far

The PC was built by Overclockers and has the Phanteks AMP GH 850W 80PLUS Gold ATX Power Supply Modular. I'm sure this is more than enough power and am presuming Overclockers have used the correct cables.

As far as I can see everything is plugged in and connected. I've checked BIOS and the primary GPU is set to the PCIE option, and BIOS is enabled. The WiFi antenna is also attached. WiFi works fine, except in Windows Safe mode, even with network support enabled where the PC won't connect to the home network.

The system isn't overclocked as far as I know, it's not something I asked for and I don't have enough knowledge to do that sort of thing.

Apparently the phone lines are working now.

My first (and only) guess would have been the power cable for the GPU may have been dislodged by the expanding packaging.

Have tried removing the cable and plugging it back in fully?

I wonder if it's the same 'qualified technician' building/testing it as the guy with the 5090 pre-built?
Getting output via the graphics card via plugging a DP/HDMI cable in, is about as basic as it gets.
Shocking if it wasn't checked, considering how long it takes to 'build' the system and dispatch it.

Yeah I see that the phone lines are unavailable message has been removed, so I'm hoping someone from OC contacts me tomorrow as the ticket has been in the queue for nearly 7 days! I've not tried removing the graphics card or cables yet and re-seating them, but even if that worked I'm not sure why this would be interfering with the Bluetooth or result in the EFI partition needing a full repair.

I also thought that as it states on the configurator web page "Expertly Built, Optimised and Tested." That is definitely not my experience so far!

Dinerty · 11 Dec 2025 at 17:48

Absolutely shocking to read mate, I was thinking about getting a new pre-built from here to.

I would still phone them and not wait for them to contact you.

Try reseating the cable only until you speak to OCUK.

Not sure how they go about testing the system but wonder if when they have finished, they reset Windows and that has somehow corrupted the EFI partition.

May be easier just to reinstall Windows, but again speak to OCUK first.

Did you try and ring them/they ring you @boomstick76 ?

I phoned support yesterday and spoke to someone, it didn't seem like anyone had read the web ticket I submitted 7 days ago
So I explained the problems and was told it's probably best to refund it, which isn't really what I want to do, especially considering the prices have gone up so much in the past week or so, but with the system being as unstable as it is a refund is probably the safest option.

I'm so sorry that you've had such a bad experience, this really isn't on, let alone when buying a new system.
I hope that you get it sorted.

Crazy seems Ocuk standards have dropped you expect far better pretty bad.

This is negligence at it's finest.
There are no excuses if the competitor can fulfil all expectations, regardless of the 'time of year/sale on'.
Despite buying smaller items, I'll never trust OCUK for anything of value, let alone an RMA - there's a reason many of us use the alternatives, and have long before the business was bought out, but even before, they had issues others didn't and often overprice and still charge delivery, of which if you pay for next day, is only honoured 'if' the orders put through that day, which as we see time and time again, isn't.

boomstick76 · 23 Dec 2025 at 12:00

As an update I can confirm that after contacting OC support on the phone and explaining the problems I had, I was offered a full refund rather than a repair. The PC was collected by DPD on 15th December and sent back to OC. I received notification on the 19th December from Paypal to state I had received a full refund from OC. So, all in all the matter was resolved and I got my money back.

However, I can't help but wonder what has actually gone on with this whole scenario and why the OC service has taken what seems to be a huge hit over the past few months. I am grateful to the OC support guy I talked to who arranged the return and refund, that aspect of the service was fine. But my confidence in the business has taken a hit as there was clearly issues to be warry of.

The PC configurator webpage clearly states "Expertly Built, Optimised and Tested", but I disagree with the optimised and tested whole heartedly. The physical build itself looked fine, as in no damage to the case, loose cabling or rattling etc. The PC was clearly not optimised (not to be confused with overclocked as I had not asked for that), but out the box the Nvidia, Bluetooth and BIOS were all not up to date based on the software versions available before I received the PC. I would have thought at the minimum optimisation would involve all the drivers for all the components to be updated to the latest available versions.

As to the testing the PC didn't work out the box from day one upon initial power on. So what testing was actually carried out? Windows identified the GPU intermittently so it would only have taken 2-3 restarts to see that the GPU was missing in device manager. The onboard Bluetooth never worked with any device trying to connect, so this was not tested. The fault on the EFI partition was there from day one, so no Drive 0 testing could have taken place and been okay with that surely!?

I've not had any further messages from OC about the return, they haven't even sent a message from themselves to say a refund was on the way, that message came from Paypal. I've no idea what diagnostics were attempted on the PC or what the actual problems were. It's almost as if the whole order has been written off.

Fortunately the PC was not a Christmas gift so there's no "Oh woe is me Christmas is ******!" from me. But I am left wondering what to do now, and where actually to spend my money to get a decent rig?

Final thoughts:

Return process went well when the phone lines were re-opened and a full refund has been issued.
Very low confidence in the "Expertly Built, Optimised and Tested". Clearly not the case.
Was the system built "as new" but using returned or second hand components? Don't know, but this has been suggested.
Black Friday may have been a busy time for OC and they took on more than they could handle, but considering the negative reviews over the past 8-weeks I'd say they have lost an awful lot of reputation as a result. Was it worth it?
Turning support lines off is not a good strategy at all, irrespective of the situation.
I only just closed my original support ticket as it was still open after 18 days HAHA! Shouldn't OC have done that after the refund??

Thanks for reporting back, I'm glad to see you got your refund.

My guess is that shipping damage to the graphics card, or to the PCIE slot are one of the more common issues in pre-built PCs, just due to the sheer weight of these things nowadays, so the fault might not have been evident at the time?

Code 45 is often something that pops up with a hardware fault.

boomstick76 said:

Obviously I can't say if it was present before it was shipped, but this (WIFI/BT issues, including random cease to function) seems to be a common fault, across multiple boards.
