PC Hardware Diagnostic Error codes

[Fyrie]

Hello,

I've had my computer randomly crash sometimes. So I ran the PC Hardware Diagnostics for Windows and came across some failures. ROM TEST failure with no error codes given and IRQ test failure with the code: RGFQX3-72293K-MFPV61-88CU03

I cleaned my computer not too long ago. Cleaned the insides as well as use CCleaner once a month or so. I've also defragged some time back. I've 8GB memory and do use my computer every day. My warranty has expired but I've a spare hard disk. Should I replace the hard disk or can I fix or refresh my current one?

Thank you

Oddly, that error Code translates as 

Network Card IRQ Failure

So it is apparently not the hard drive but perhaps some Windows system error or a problem with the wireless or wired ethernet card. Those could easily cause a crash while you are accessing a local netork or the internet. Nothing will lock a computer up faster than two devices trying to occupy the same interrupt. This was a problem in the Windows 3.1/95 days but rarely happens now. 

Open an elevated command prompt (run as administrator) and enter sfc /scannow and see if you return any Windows system file errors. 

Post back with any other questions and please accept as solution if this is the info you needed.

I thought that could've been it because I did switch out my network card Realtek to a broadcomm BCM94352HMB. I wanted faster speeds and it was doing the job. But after reading the reply, I switched back to my realtek card, reinstalled the driver, and ran the diagnostic again.

Although the ROM test passed this time but the IRQ test failed again with the same error code:

RGFQX3-72293K-MFPV61-88CU03

Any other solutions?

I finally figured it out. I realized that my ethernet driver was disabled and was giving me the error code for that. After enabling it, the test does pass. Hopefully that wasn't the cause for the random computer crashes.
