Computer freezing, crashing, failing to restart... HDD suspected

Hi there, I've been having troubles with my PC on and off for the past few weeks now, and I cannot pin down what is causing it. Just before while using Photoshop I got error 36, which occurs "when reading or writing to the scratch disk", causing it to crash. Right after, all applications began to fail until Windows Explorer went and I had to restart. The error code 0xc0000185 comes up again and again;

"The instruction at xxxxxxxxxx referenced memory at xxxxxxxxxx.

The required data was not placed into memory because of an I/O error status of 0xc0000185."

This would keep on occurring immediately after starting up. When I got the chance I ran the WD lifeguard diagnostic tool, which failed immediately with error code 02 - due to a hard or soft reset.

I opened the case up and pointed a fan in for a while with the PC off, and it is now working fine - the HDD passes the test. To give a bit of background, this is the latest of a litany of problems. It has been crashing with Kernel error 0x0000007A, then been unable to detect my HDD when booting up (0xc00000e9) - usually it needs to be left off for a while - I do use my computer for up to 10-12 hours at a time, but rarely anything intensive and I haven't discovered any overheating problems. It has crashed and said it was an issue with the display drivers, which I have uninstalled and reinstalled. I have tested all the RAM individually with memtest, as well as all RAM slots, which have passed, though doing a test shortly after a crash also yields errors, as with testing the HDD. I have also wiped the HDD and reinstalled Windows 7.

I've looked around the Internet, but the issues seem to vary from thread to thread, so I'm kind of at a loss. The HDD does seem to be a recurring factor, but I can't know for sure. Have you guys and girls got any suggestions? Anything is welcome! Cheers.

The temperature seems to be fine. If switching the cables does not work, the best thing you can do is just to borrow a HDD from someone and attach it to your system and see if it will work. If the problem persists you can do the same with the PSU. You just need to rule them out one after another as a cause for the issue. Anyway, I would place my bet on the HDD.

Hi there max7773,

As the HDD is a possible cause of the issue, I would advise you to back up the important data that is on the drive as soon as possible.
Apart from that, I/O(input/output) error could be caused by some connection issue. So, you can start by swapping cables and connecting the drive to another port.
After everything works fine when cooling it with a fan, I would suggest that your issue may be heat related(dust cleaning may be a good idea). You can download some software in order to check out the HDD temperature. Another thing that suggests overheating is that the computer should be left off for a while before working again.

Cheers,

@netnavi: Hadn't really considered that - it seems like a possibility. I looked into testing that though, and it seems the only real way is to buy a tester and measure it. I'm not that savvy, but I'll definitely keep it in mind should nothing else turn up. The PSU is as old as the machine, so, 6 years.. wouldn't be surprising if it's on its way out. Cheers!

@D_Know_WD: I'll give that a try for sure. And yup, got it all backed up, which is a massive relief. The HDD seems to hover around 35 degrees celcius, which I believe is normal (?) I've also cleaned it out recently, so the airflow is pretty good. I ran a chkdsk /r today, but I wasn't around to see the results. However, the computer crashed within 5 minutes of starting again, after being left off for almost an hour, so I guess it didn't do the job. I'm starting to lean towards a power supply issue after looking into it (making this thread in the wrong section I guess!), but who knows. I'm going to run some more tests over the next few days and see what that yields - I'll keep you up to date of what happens. Thanks for the reply!

Hey, just want to give a quick update just in case anyone has similar problems (I hate reading threads and finding things unresolved at the end). I've tried switching the HDD cable, and also unseating and reseating the graphics card, and as of a few weeks now, my PC is behaving fine! I also disconnected a DVD R/RW drive which had been causing errors in the Event Log. So, any one of these things could have been responsible in some way or other. Thanks for taking the time to answer - 'tis much appreciated.
