Windows 7: BSOD after taking in PC to repair shop

I had a chat with Jonathan about this and we agree the next pursuit should be a Power Supply.

Quote:
The post makes me think PSU because it seems to get much worse when a video card is installed, although BSODs exist with only onboard graphics too. I'm guessing the increased power draw of the video card is putting it farther over the edge.

Other than that, motherboard would be my next guess, but if I had to recommend a purchase, it would be PSU first.

The "BOOTMGR is CORRUPT CHECKSUM DOES NOT EQUAL" error may be due to BIOS/CMOS corruption or boot files.

Have you tried clearing the CMOS again?
How To Clear CMOS
You might need to get a new CMOS battery.

Also try:

What have you done since the memtest86+ test with +1 million errors?

If you have reset your BIOS, are the RAM settings at default?

What are your DRAM and CPU/NB voltages set at now?

Yes I have tried clearing the CMOS.

I have not changed the CMOS battery though...are they the same as watch batteries?

I could make a quick visit to my local store and buy one.

The most common is CR2032.

Shut down your system and unplug it from the wall, then take out the battery from the motherboard and check the number on it to be sure.

I bought a new battery, installed it, turned on my PC and after about 30 mins it crashed.

Do I have to clear the CMOS after installing a new battery?

Go to your BIOS and change the CPU/NB voltage to 'Manual' and 1.200v, and the DRAM voltage to manual and 1.560V.

Run memtest86+ again, for 7 full passes, if you get an error you can stop the test and let us know what happened.

Be sure you are running memtest86+ and not memtest+.

I changed the values, ran memtest+ and no problems.

Been using the PC all day and not a single BSOD.

I'll be gaming on it tomorrow, if it doesn't crash I guess it's fixed?

I'll let you guys know!
