Atapi.sys and Netio.sys BSOD.

A morning freeze may occur by a number of reasons.

Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

Check if the Power Supply Unit (PSU) supplying adequate power to the computer or not.
eXtreme Power Supply Calculator
Also let us know the wattage of the PSU.

Plus, a dismantle, cleaning up and re-seating of hardware may help a great lot.

Also I will eager to see what Britton30 suggests.

Windows 7 requires bit of more system resources than XP to run flawlessly.

Let us know the result of memtest.

Should I try re-installing windows 7?

Not a bad idea.

At least it will let us know whether it is a hardware issue or a software issue.

Ugh...
I just did a fresh install of Win 7 and ran Prime95 and it only ran for one hour and 15 (or so) minutes before it crashed , but it didn't report any errors (in Prime95) :), and it didn't BSOD, so there are no dumps to analyze .

At this point we need to know the system temperature. Is the computer hot? Report us the heat of the computer after a couple of hours of your normal usage. Upload a screenshot of the summery tab of Speccy. Alternatively, you can publish a Speccy snapshot too: Speccy - Publish Snapshot of your System Specs .

It is not sounding good, if there is not an information gap.

Before taking a big decision, can you spend some more time on attempt to troubleshoot?

First run 8 more passes of Memtest86+, if it is free from errors again, enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

   Information

Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

   Warning

Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

   Tip

• If you fail to get on the Desktop because of DV, Boot into Advanced Boot Options > Safe mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
• If you cannot boot in Safe mode too, do a System Restore to a point you made earlier.

Let us know the results, with the subsequent crash dumps, if any.
