CDP import crashes PC

[pfx]

I think this may be related to my previous issues rather than Trainz, but on trying to import a cdp file, everything goes fine initially, then the CPU usage shoots up to 95%+ causing a PC shut down. Has anyone else experienced similar or should I continue to the PC doctor?

Thanks,
Innis

Loading 95% when unpacking the cdp file is fine. Just delete PC doctor permanently and everything will be fine.

And in the future, do not install such crafts, the built-in Windows Defender is enough.

Increase your Windows swap file to at least 1.5 times your installed RAM. This may help with that issue. PC Doctor does use a lot of resources and it's okay to run but not all the time because of that so remove it from your system start up.

Ahhh, lost in translation perhaps. I meant taking my PC to the PC doctor along the road.

Okay, so I altered the the swap file. I noticed that the existing limits were well below what was being recommended, which were similarly below the 1.5 x RAM minimum and 3 x RAM maximum. Once I've tried testing a cdp import, I'll report back.

Thanks fellas.

I tried importing a cdp this morning. Seemed to be going okay then the CPU temp started to go up (still within tolerable levels) and CPU usage hit 100% and PC shutdown.

Back to the drawing board.

Increase the swap file again. Try 2x and see if that works. Sometimes, this is necessary.

Thanks for the advice. I'll give that a go.

I'm taking it into the PC repair man tomorrow. Hopefully he can get things up and running again.

Good luck. Let us know how it turns out.

Curious how large is that .cdp file?

Latest update is the PC guy couldn't work out what was wrong, short of a possible PCU issue but he didn't have one with the correct connections to find out. At least he didn't charge me for it. I'm going to try another place.

@Forester1 the file is 833MB. I installed it before no issue but deleted the files. I've tried a number of cdps and I get the same result every time.

 

[martinvk]

While large, 833 MB is not unheard of these days. What are your computer specs. Since it worked in the past, did anything change since that time. Perhaps less free disk space? New apps interfering?

 

[grazlash]

My PC regularly loads route backups of over 2 gigabytes, unzipped and using drag and drop onto CM (can't use .cdp as the file size is too large). I don't play around with swap files or use dubious external "doctor" apps which seem to do more harm than good. Your PC specs will definitely have an effect on what you are able to do with large files. I have a mid range PC with an AMD Ryzen 5 5600, 32gb DDR4 ram, a GeForce RTX 4060 gpu and lots of SSD and M.2 drives, I also have no problems with very large files. Quoting your PC specs would greatly help with diagnosing your problem.

Now let's ask Captain Obvious. Have you tried another large CPD besides the one that's causing the crash? It could be that particular CDP is corrupted. I've had that happen before requiring me to download it again. Hopefully this isn't a back-up of something of yours that's corrupted.

Sometimes, us tech people get mired down the techy things and forget to try the easy stuff first, been there and done that many times.

 

[pfx]

It's definitely not Trainz. The guys trying to fix it (and I trust them, they've fixed other gear of mine previously) have found a number of software issues, and possibly one hardware issue that is causing the problem. It was news to me that I have two separate operating systems on the PC, on two drives. One was corrupt.

Fingers crossed, these guys should give me back a functioning PC.

The tech lad has had my PC for over a week now and has still been unable to find a cause to this problem. The final attempt will be changing the motherboard so I'm hoping he'll bring me some good news on his next call.

 

[Forester1]

Weird. Is that the only function that causes it?

 

[pfx]

No, it also spins up the fans and shuts down for no apparent reason shortly after booting. Even the tech is baffled and says it's a unique issue.

So after almost three weeks, I finally got the call I wanted from the PC shop. Apparently it's a motherboard issue causing a sudden spike in CPU temperature and a premature shutdown. The guy tried importing the original cdp file using an alternative motherboard and it wall worked as expected. It's a fault he's never seen before.

He also told me what the bill will be for a new board and the work he's undertaken diagnosing the issue. £135! At that sort of price, I've no idea how he hasn't gone bust.

Wow, who would've thought this.

I agree, how does he stay in business with those prices? From what I've been reading, repairs never make any money anymore due to manufacturers obsoleting parts so quickly that it's difficult to get a hold of them. His repair for you is just about the cost of the new motherboard.
