Windows 7: Computer Freezes ACER Aspire M5300 windows 7 home premium 64 bit

Hi!

My computer freezes randomly 1-5 times a day. The only event I could connect with freezing is a fast mouse movement but sometimes it freezes with no activity from my side at all. The computer is frozen and do not answer on Ctrl-Alt-Del n o mater how long I am waiting. The only way is to press on-off button and restart the system.

No BSOD at all.

Graphic card is new, changed by the ACER service.

I run Memtest86 - passed no errors. Memory 6GB.

I am occasionally running LINUX from CD or USB and the computer newer freezes in LINUX only in Windows 7. I am running different LINUX flavours mostly UBUNTU.

Talked several times with Acre support in UK (despite the fact that I am in Sweden) and reinstalled the system several times to the factory state.

Antivirus up to date, AVG Free 2011 and AdAware. No signs of infection.

I have run the system diagnosis tool from control panel and there are only 2 errors in test report:

• The device, PS/2 Keyboard, is reporting tv_ConfigMgrErr24 Plug and Play-ID ACPI\PNP0303\4-4E6C81F-0

• Microsoft PS/2 Mouse, reporting tv_ConfigMgrErr24 Plug and Play-ID ACPI\PNP0F03\4-4E6C81F-0

I have USB mouse and keyboard attached to the computer now but at the beginning used PS/2 units via a mouse/keyboard/monitor switch.

I installed again PS/2 mouse/keyboard and uninstalled according to runes but the same errors are again in the report.

I am running mostly MS software on the computer except the e-mail program which is Mozilla Thunderbird in Windows XP SP2 mode.

All drivers are up to date. The audio driver, network card driver and video card driver are downloaded from the producers.

Is there any idea what to do?

Thanks and regards

hi i can say go to acer website download the latest bios an flash your machine. its not the software as i have the same machine and running the software on my other machine with no problem.

hi yes it is the bios

I have the same problem as above, same computer,specs and everything.. However, I updated the BIOS.. still not solved the problem.

hi download a new copy of the bios file M5300 not m7300 but they is all the same from acer website with no antivirus on system back your old bios up and try reflashing your bios in dos mode. and with no antivirus software on your machine after which restore the computer to factory default. and see it that work

Hi did you upgrade your machine to s 6 core

I can't get past the boot-block so I am not sure wheter or not it has been upgraded succesfully.

Well I have the same problems (freezing) with an Acer Aspire 5738G also never fixed by the acer fix service

Acer,
Maybe I'll try the ubuntu live usb and see if it crashes maybe it's the hdd ??!

Hi if you are flashing bios in windows. one the right bottom cornner of bios rom panel thick the box that says (do not check rom id) and it will work. hi have you upgrade you machine to a 6 core cpu. if yes your motherboard is the problem because up grading to a 6 core you will need a new motherboard. they are two motherboard model that looks the same but they are not the same the motherboard that will run 6 core cpu. the board must have( 6C )at the end of the part number (6C is for 6 core) acer will not tell you that but that is what i found out. and board is about euro130 to euro 140
