steam crashes my whole computer

Either hardware related or driver. Windows technically can also crash the computer but most times its the other two.

You'll need crash dump files posted if there are any or something else to go on of similar nature than the nothing that you have.

Hi Julian. I'm Greg, 10 years awarded Windows MVP, here to help you.

2) Update your drivers and BIOS/UEFI firmware from the PC or motherboard maker's Support Downloads web page, using the full model number, Serial Number or Dell Service Tag on sticker. Compare the latest drivers available for download with the ones presently installed in Device Manager reached by right clicking the Start button. Make sure you have the latest BIOS or UEFI firmware, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

Updating drivers from the Device Manager or Windows Update is rarely enough. The most basic thing we need to learn to maintain a PC is keep the latest manufacturer's drivers installed from their Support Downloads web page. Everything else depends on this.

3) Go over Windows using this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 16 to test a new Local Admin account to replace yours which may be corrupted. Then if necessary continue with the other steps to go over your install most thoroughly.

4) If nothing else works then do a Repair Install, by installing Media Creation Tool, open tool and choose to Upgrade Now. This reinstalls Windows while keeping files, programs and most settings in place, is the most stable method to advance to the latest version, and solves most problems.

Julian, Where are the results of the steps I gave you which most often work for the problem? I am standing by here to help you further, but I need to know the specific results so I know what else to try.

This is an interactive process. I give steps to perform, you do each one and then report back results until something works, so I know what to suggest next. If you need help performing any step, just ask back. But please do not skip any steps. We often find out the skipped step is the fix.

I have a video now of it crashing you want me to show it to you
