Okay so leading onto my issue.

It happened again today while playing CS, tracked it down in the Event log and found this, can anyone make any sense of it?? :S

The device, \Device\Ide\iaStor0, did not respond within the timeout period.

Well iaStor is part of the Intel storage drivers for your SATA drives, so it would seem one of your drives was polled and it failed to respond, most likely due to it being busy.

Have you monitored it with Resource Monitor yet?

Have you updated your chipset drivers?
Also do you have an SSD?

Not a clue and yes, my OS, PS2 and CS:GO are on my SSD

@Phattie - it just says system with a huge amount of data being written

The second tab under Disk called "Disk Activity" should show you exactly what you need. Sort it by the Write column and you can see exactly what file is being written to.

Okay, ill check it tonight again and post my findings

Btw I'm assuming it's a write-intensive process that's causing your issue, but it may very well be read or a combination of both. Try the Total column as well.

I also have a bit of a strange issue with my Graphics driver, I run Win7 Ultimate 64 bit version, the problem is every time my PC is re-started once it has fully loaded I have to re-install my driver before playing PS1 , if I don't do this it takes ages to load sanc and if I go to desktop then want to get back into game it also takes ages to get back to the game screen ?

I have yet failed to find the cause for this behaviour, if anyone has any idea why this is , I would be very grateful.

P.S. I would also like to know where exactly my old drivers are located as when I re-install them there is quite a long list of old drivers which I no longer need on my SSD drive. Thanks.

Does it happen with any other game?
What gfx card do you have and what driver?

No it only happens with PS1 my Graphics card is the GTX 560Ti driver version 4052.

You should update your driver anyway, you're using one from over 6 months ago. Uninstall your current driver and install the new one (if your computer doesn't do it automatically for you).
Latest one for your gfx card: http://www.nvidia.co.uk/download/driverResults.aspx/81905/en-uk

If that doesn't help at all you can just download your old driver if that worked better.

How long has it been happening?

Thanks Ryoka, I installed the new driver but I still have the same issue of having to re-install it once my PC has fully loaded before Playing PS.
It's always done this ever since I had this PC.

If I were you I'd reinstall PS1, it seems like the game is having the issue not your PC. If all other games work then that's the only real possibility.
