Computer locking up shortly after boot

Nolan314 · 25 Nov 2013

I'm having some difficulty diagnosing this one, but I think it's the graphics card. Shortly after booting and logging in, the computer locks up on a fairly random basis. The only known way to get out of it is forcing a reboot. I tested the hard drive, ran Windows through a system test, updated the drivers, and tested the RAM, and all of it passed. The HDD test did tell me that the drive overheated once, but it passed the long test, and Windows SFC found no violations.

Download HWMonitor CPUID - System & hardware benchmark, monitoring, reporting and use it to check your voltages, your PSU may be faltering.

Here's a GPU test.
Some hardware tests to run.

Graphics card test:

Video Card Stress Test with Furmark

Will this test an integrated card?

It can test the Intel integrated graphics but it's more for a dedicated card. The test runs badly on integrated graphics usually under 10-12 FPS.

I replaced the PSU, and it's still locking up. The only thing I really have left to test is the processor and mobo. Any ideas for how to do that?

Did you run the GPU test I linked earlier? The motherboard can't be tested per se, but you can test the RAM and slots and hard drivethis way:

Hard drive(s)test(s):

Pick one for your HDD brand or use Seatools.

RAM (memory) test:

This will require memtest on a bootable CD or USB stick.

RAM - Test with Memtest86+

The graphics card test seemed too much for the graphics card to handle. It's the built in card. I can't remember what motherboard it has, but it has an i3.

Also, I already tested the RAM and HDD. Those were my first steps. I also tested the OS, and no integrity violations were found.

You can Hardware - Stress Test With Prime95 to test the CPU, but please watch the temp, it can stress an i3 a lot. I recommend Core Temp instead of Speedfan though.

What are the spec of what you're working on?

Nolan314 · 19 Dec 2013

I already have Core Temp installed. The system has an Intel i3, Asus P8H61 mobo, Cruicial Ballistix Sport 4GB RAM, Samsung Spinpoint 1TB HDD, and an Antec VP-450 PSU.
