random crashes in BIOS + games

Specs: Windows Vista 64, below
Hello, Im having a weird and frustrating problem, wasn't sure where to post this!

Anyway, the problem started with a 3d game (cod4); my system would randomly crash after a few minutes of play - the monitor would go into power save mode and I would have to manually reboot with the power button to get back into windows, and if I didn't wait a few minutes after switching off the pc before repowering it would often crash into the same blank screen on the windows boot.

Then this started happening while in the menu of the game, not actually playing. And now it's occuring in the BIOS! At first after about 2 minutes in BIOS the pc would crash in exactly the same way as it did in cod4 (monitor goes blank, have to reboot), but now as soon as I enter BIOS it will crash (within 5 seconds). Temperature is normal btw. Before the BIOS crashes began I suspected it was power supply problems, overheating or driver related, and I reinstalled everything short of a full reformat. I also removed an X-Fi soundcard that I got recently in case it was power related but that didn't help... and now since the crash is occuring in the BIOS (i was in there to disable onboard soundcard) I have no idea what to do, I'm worried it's a virus or something, although a full system scan with Kaspersky doesn't turn anything up.

If anyone could give me a hint on what to do now I would be very happy, as I am really very frustrated and I am totally out of ideas. Even a reformat seems useless since the crash (which started when playing a 3d game) is now happening in BIOS!

ps: Windows works fine - the only times I've experienced this crash is when I'm either playing cod4 or in BIOS (?!).

Thankyou very much in advance, system specs below:

If it's happening in the BIOS, it's most likely NOT a virus. You say the temp is normal, yet fail to back it up with any numbers. I guess we can safely assume your CPU idles under 40C then?

Looks like your board is a Gigabyte GA-965P-DS3:


And your CPU is a "2.40 gigahertz Intel Core 2 Duo" with "Bus Clock: 266 megahertz" so it's probably an E6600:


You have 2GB of RAM but there's no info on make/model or speed. And I don't see anything listed about the graphics card or power supply. The power supply specs are very important because random reboots are often caused by an inadequate unit. Post back with the make/model, wattage & amperage ratings on the +3.3v, +5v & +12v rails.

Yes sorry about that, Im a bit of a noob to this.

Hopefully this information is what is needed:

Power supply says:
Antec Model Neo HE430
430 Watt output

AC input 100V - 240V~ 7A : 50HZ / 60HZ

DC Output Voltage +3.3V +5V +12V1 + 12V2 + 12V3 -12V + 5VSB

Max Current 22A 14A 16A 16A 16A 0.8A 2.5A

Available Power 72.6W 70W 384W 9.6W 12.5W

Total power 430W continous output @ 50 degrees temp

RAM is: Kingston HyperX DDR2

THe processor is Intel® Core™2 Duo Desktop Processor E6600. Thermal design power 65W, VID Voltage range 0.85V - 1.5V

Vid card is: NVIDIA GeForce 7950 GT

Also the monitor is a bit old and is generic:

CMO CMC 19" AD [Monitor] (19.1"vis, May 2005)

I hope this is okay, thanks very much for the reply!

Oh and also, the temperature was 43 degrees, but BIOS crashed even if the computer has been switched off for a long time, within seconds of booting into BIOS.

Also, I have flashed my bios this morning, the flash worked perfectly but the problem is the same.

Your PSU is 430W, is very low for your computer specs, specially for that 7650GT.

Seems to me that your machine is starving for power.

At least a 600W PSU should be fine.
