BSOD in Flash and games, computer forgets BIOS and time when off

I imagine you get a lot of problems like this, but I haven't been able to find any which correspond to what's been going on with my computer.

Briefly, a few months ago it started badly misbehaving. Flash videos normally caused a BSOD, and certain games also produced a blue screen, although the error it came up with was almost always different. Sometimes the games just froze up with or without strange graphical error, and I needed to restart. Very occasionally it would blue screen without any provocation, just when logging on or something.

In addition, whenever the computer is off for more than a few minutes it gives an error on booting saying that it has lost its BIOS settings, and when I log on I need to update the date and time as it resets to 2001.

I have tried reinstalling graphics drivers completely using driversweeper, and have replaced the motherboard battery with a new one. I also did a clean reinstall of Windows (I do one anyway every now and then, to keep things tidy).


The computer is useable but all these problems are quite annoying. As far as I can remember they all started at once.
I have attached the stuff mentioned in the BSOD thread.
Computer is 4 years old, self built, ran fine before. Windows 7 Home Premium 64bit, Full Retail.

PLEASE HELP!

You need to replace your CMOS battery. A classic sign is "forgetting" BIOS settings and time when off. We need your system specs to be of any more help.

As I said, I replaced the BIOS battery when it started with no success. I've just tried that again with one that definitely works (new, tested in a calculator) which hasn't done anything.

Older versions of ASACPI.SYS are a known BSOD problem on Windows 7. Update the driver by:

1. Going to the Asus motherboard support site
   When you reach the website:
2. Scroll down the page and click Utilities
3. Hold Ctrl and press f (ctrl+f) to enter the browser's find feature
4. Search for "ATK0110 driver for WindowsXP/Vista/Win7 32&64-bit" (without quotes)
5. Download and install the driver.
6. After installation is complete, verify that it installed correctly.
   
   • Click Start Menu
   • Click My Computer
   • Go to C:\WIndows\System32\drivers\
   • Verify that the ASACPI.SYS file is dated 2009 or newer (2010,etc.)

Thanks to JMH and zigzag3143 for the above information.


Your crashes primarily indicate hard disk problems. This could mean hard disk corruption, bad sectors, a failing hard disk, Windows files or registry corruption, viruses, or memory problems.

• If you are overclocking any hardware, please stop.
  
  
• Run Disk Check with both boxes checked for all HDDs and with Automatically fix file system errors checked for all SSDs. Post back your logs for the checks after finding them using Check Disk (chkdsk) - Read Event Viewer Log (you may need to search for wininit instead of chkdsk).
  For any drives that do not give the message:
  Windows has checked the file system and found no problems
  run disk check again as above. In other words, if it says:
  Windows has made corrections to the file system
  after running the disk check, run the disk check again.
  
  
• Run the short and long tests with SeaTools for HDDs.
  SeaTools for Windows
  
  SeaTools for DOS
  
  
• If you have an SSD, make sure the following are up to date:
  • SSD firmware
  • BIOS Version
  • Chipset Drivers
  • Hard disk controller drivers/SATA drivers
  • If you have a Marvell IDE ATA/ATAPI device, uninstall it in device manager and see if the system performs better.
  
  
  
• Check Windows for corruption. Run SFC /SCANNOW Command - System File Checker up to three times to fix all errors with a restart in between each. Post back if it continues to show errors after a fourth run or if the first run comes back with no integrity violations. Use OPTION THREE of SFC /SCANNOW Command - System File Checker to provide us with the sfcdetails.txt file if errors occur.
  
  
• Download and install Malwarebytes, update it, do not start the free trial, and then run a full scan. Also run a full scan with your antivirus software installed on your system. If you do not have antivirus software installed, see the Good and Free system security combination. for better security steps and scanning tools. Make sure to update the security software before running the full scan.
  
  
• Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).
  
     Warning

  Before you proceed with the following, answer these two questions: Are you still under warranty? Does your warranty allow you to open up the machine to check hardware? If you are unsure of the answers to these questions, contact your system manufacturer. WARNING: The steps that follow can void your warranty!!!
  
  For Part 3: If You Have Errors: If you swap any memory components, follow these steps for ESD safety:
  
  1. Shut down and turn off your computer.
  2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
  3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
  4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.
  
  Once these steps have been followed, it is safe to remove and replace components within your computer.

For your BIOS/CMOS issue: keep in mind that this may indicate a failing motherboard. It may also be indicative of another hardware failure. We may have to do further debugging to determine the problem.
