Need help figuring out a couple problems with my PC...

#1SychosisDragonPosted 8/28/2013 5:20:58 PM
I recently took my PC into the shop for upgrading, maintenance and fixing. The motherboard, CPU and RAM have all been replaced. But since then, a couple concerns have arisen.

The first problem I'm having, is that my CPU is showing up as a dual-core when it's actually a quad-core, in both the device manager and the BIOS. I just had the CPU replaced so I was thinking maybe the drivers are not updated. Regardless, I'm not sure what CPU is in there now, and if the PC guy didn't actually replace it, I need to beat him up. How can I find out for sure what CPU I have, without having to remove the heatsink?

The second problem, which doesn't seem like much but I don't want to ignore it just in case, is that the first day I had my PC back, after about 4 hours of being turned on, randomly shut itself off. Upon attempt to turn it back on, it turned on for about 5 seconds, then shut itself off again. I kept trying to turn it on with the same results. After a while, I noticed the num lock light on the keyboard was always on, even when the PC is off, which either I've never noticed before, or that's a problem. So I tried shutting off the power in the back of the PC, waited 20 seconds, flipped that back on, and now the PC boots up fine. I haven't had a problem booting up since, but to be safe, I wanted to address it. Is this significant?

Any help would be appreciated.

Download CPU-Z to find out more about your chip without taking it apart.

Random restarts could unfortunately be caused by a broad array of things. That is going to require that you return everything to stock settings and slowly eliminate what could be the problem.

I plan on buying a new hard drive and installing a new OS and starting from scratch on that. By 'restore stock settings', would that constitute as a solution?

Yes, on some things, no for others. For example, your CPU overclock has nothing to do with windows...that's set up in the BIOS of your mobo. I'd recommend going into BIOS and restoring everything to default when you begin troubleshooting.

I had a feeling it might be that as well. I haven't changed any BIOS options but when I put the new HDD and OS in, I'll restore it to default. Still not sure how to go about finding the problem once I do that. I know some things but that's out of my area of expertise.

Google "event viewer" and after a crash, pull that up. If it tells you there was a sudden power lose, it's probably the PSU.

As far as checking the CPU; like the other guy said, download CPU-Z and it will tell you exactly what kind of CPU is running.

Basically, when you start over, set everything at default for a few days. See what happens. If nothing, you either replaced what was causing the problem, or changed the conditions that were causing the problem. From there, you want to change only 1 thing at a time, so that if weird stuff starts happening, you only have 1 factor that recently changed and you can isolate the problem area more easily. I'd start with the CPU overclock, since it is one of the most likely things to blame...either instability or getting too hot can make your PC crash or shut down. Then the GPU overclock, then other smaller settings in the BIOS and Windows.

If you get everything how you want it, you can test stability further using a program called AIDA64. It has a 30-day free trial. You can run a stress test on everything, or just a certain part of your PC with the program, as well as monitor temps and voltages while it's going on.

Thanks guys. Getting on this right now.
But am I wrong on the keyboard thing? If the PC is off, shouldn't all the lights on the keyboard be off as well?

Upon looking through Event Viewer, the only errors it shows before my PC crashed is that some programs were trying to access my D: as a hard drive, though my D: is a DVD burner. My E: used to be set as D:, but when I had my motherboard replaced, the PC guy switched the labels. Now D: is E: and my D: is a burner. I guess some programs are still associated with the D: and think it's the HDD. Would this cause a crash and problem booting back up though? And would replacing the HDD with new OS, and reinstalling any programs fix this?

You can very easily change which drive letter goes with which drive.

-On the desktop, right click My Computer and choose 'Manage.'
-Then go down to Disk Management (under Storage)
-Right-click on the drive you want to change and choose 'Change Drive Letter and Path'
-Change it to whatever available letter you want. If it's not available, another drive is using it and you'll have to temporarily name it to P or something to free up the letter D.

Typically, in any modern BIOS, you get to set your priority boot device, so you can set it to your HDD or SSD if you have one, instead of your disc drive.
